Introducing DoDream Services & DRM

Hello! We are DoDreamChain:)DoDream is an integrated study abroad support program that provides various services for international students and related institutions as well as Korean culture and Korean language education, study abroad information, and study abroad review sharing.Today, we’re going to talk about Dream Guide and Do Play.Start of DoDream study abroad service — Dream GuideKorea’s study abroad environment is not that bad compared to other countries. In addition, the number of international students is exploding due to the trend of K-pop and the policy of the Ministry of Education. However, many problems such as financial damage caused by unverified brokers, inefficient document management, and formal support for international students have also emerged, leading to a decline in satisfaction with studying abroad, and some are concerned that studying in Korea may become a trend.The first service we have prepared to address these issues is the Dream Guide. Dream Guide is a personalized study abroad design service. It discloses information from about 300 universities, designs appropriate courses according to the conditions and circumstances of international students, and helps students preparing to study abroad gather fragmented information to check it quickly and easily. Through this, it prevents damage from unverified brokers, reduces the cost of studying abroad, and guides students to counseling to a verified study abroad center if they need it. Dream Guide, which can directly design the study abroad process, will be a reliable partner to rely on more than anyone else in the preparation stage for studying abroad.Content-based study abroad support services — Do PlayDo Play helps international students get used to local culture by providing contents that they can enjoy in Korea. It provides various information from Korean traditional culture such as Korean holidays and hanbok to the latest trends such as photo attractions, local restaurant information, and concert information. Foreigners and Koreans have different views, but Do Play is managed by Dream Maker, which consists of 13 foreign students. These contents will be more familiar to international students. They share their daily tips, such as grocery shopping and receiving packages in Korea, and produce content related to Korea. As such, Do Play and Dream Maker serve as a bridge between Korea and students who are considering studying abroad.As such, Dream Guide and Do Play not only make it easier for foreigners who want to study abroad in Korea to access and prepare information, but also allow them to interpret and accept Korean culture and trends from a foreigner’s perspective. Through this, international students will be able to save money and time to prepare for studying abroad and start studying abroad in Korea more comfortably.DRM token to maximize DoDream’s cross-service synergyDoDreamChain’s core partner, Dain Leaders, is a company with expertise in the study abroad market. All services provided by the DoDream study abroad platform are designed and provided for effective connection between international students, educational institutions, companies, and study abroad institutions. The DRM token is used to accelerate the value chain of these study abroad industries more effectively and to benefit from network effects. We are evolving with a focus on building structures that realize value along with the actual growth of the platform.Furthermore, DoDreamChain is planning and implementing a program that can manage its studying abroad life and even afterwards. In the next article, we will talk about Do TOPIK and Do Talking for this purpose.

Syntropy Stack Launches Chainlink Integration

Easily launch and manage Chainlink nodes with built-in security and performance optimization using Syntropy Stack.Following the release of our Syntropy+Minecraft integration, we’re now excited to launch a Syntropy+Chainlink integration, which makes it easy to deploy and manage secure and optimized Chainlink node infrastructure.Our Syntropy+Chainlink integration:Helps adoption—It becomes easy to deploy Chainlink infrastructure. A complex process gets reduced to a few steps. Operators can deploy dozens of nodes in minutes.Increases security—Creates encrypted private connections between each and every chainlink node service in the infrastructure.Improves reliability and performance — Nodes use Syntropy’s multi-provider network, ensuring stability even if one cloud provider fails. Easy service integrations make monitoring and troubleshooting fast and simple.These advantages are applicable to most blockchain infrastructures, and additional integrations to support other networks and applications are in development.Click here to follow Syntropy+Blockchain integrations on GitHub.Syntropy+Chainlink IntegrationRunning blockchain infrastructure can be cumbersome. It requires a lot of setup, like launching a docker, creating directories and environment files, establishing an Ethereum client or third party, and connecting remote databases. Real-time monitoring and troubleshooting pose additional challenges.This complexity limits the number of people who run blockchain infrastructure like Chainlink nodes. It also poses reputational risks for existing node operators. In blockchain, node consistency and reputation are paramount. All behavior is recorded. If a Chainlink node misses requests, returns bad data, or goes dark, it may no longer be used in transactions.Given these high stakes, technology like Syntropy Stack can help reduce time and risk for participating node operators.https://medium.com/media/cc645d5affb65b2a2b97f120c9c11716/hrefWith Syntropy, setting up a Chainlink node only requires a few commands from start to finish, most of which are simple inputs into a prompt. Much of the process is automated, with easy access to service integrations that make real-time monitoring and troubleshooting possible.A Chainlink node operation in action using Syntropy StackApart from easy setup, the Syntropy+Chainlink integration provides several additional benefits to node operators.Encrypted Traffic — Built-in WireGuard tunneling provides security, stability, and performance to participating Chainlink nodes.Connecting Services — To establish a Chainlink node, many services need to be connected and secured. This infrastructure, which includes firewall creation and certificates, is a lot to manage. Syntropy Agent facilitates these connections out of the box.Redundancy Facilitation — Easily integrate tools like Nomad, Terraform, and Ansible to automatically set up a multi-cloud and multi-availability zone node system that ensures stability even if one cloud provider fails.SmartRouting — Connections made via Syntropy Stack ride on the Syntropy network, which includes 500+ locations across 150+ providers. This allows your traffic to travel through every possible path between nearly every global cloud network, resulting in tens of thousands of unique paths, protecting your node’s reputation as a fast validatorSyntropy Stack makes the process of creating and managing a Chainlink node (shown above) easier, faster, and more secure.We have great respect for the Chainlink team and the technology they’ve built. With such an important role in the blockchain ecosystem, we believe the Syntropy+Chainlink integration can further enhance their system’s node infrastructure.This is just the start. Our technology can be used to secure and optimize anything connected to the internet, including decentralized applications and networks. We’re working to make Syntropy the default network for building blockchain infrastructure.Interested in using Syntropy Stack to launch and manage Chainlink nodes?

The Third Storeman Group Begins February 1st, 2021 — Don’t Forget to Register Your Node!

The Third Storeman Group Begins February 1st, 2021 — Don’t Forget to Register Your Node!The Storeman Group has been running for more than two months since the first group open on November 21st, 2020. According to the cycle parameters, the third Storeman Group will begin its selection on February 1st, 2021.Make certain to prepare your node if you want to participate in the third group, or to register to withdraw if you are a current Storeman node and wish to withdraw.Read more below for details.DetailsSelection Time: 4:00 AM UTC, February 1st, 2021–4:00 AM UTC, February 7th, 2021Negotiating Time: 4:00 AM UTC, February 7th, 2021–2:00 AM UTC, February 9th, 2021Working Time: 4:00 AM UTC, February 9th, 2021–4:00 AM UTC, March 9th, 2021Amount of Storeman Nodes: 21 (including one Foundation node)Threshold of Storeman Node: 10,000 WAN, the Partner In mode is supportedRules To Win The Selection: The top 20 Storeman nodes with staking amount will enter Storeman GroupDelegation Fee Rate: 10%Deposit Rate: 150%Delegation Ratio: 1:5wanBridge: The Storeman Group at this cycle is applicable to Wanchain-Ethereum wanBridgeNote: If you are currently operating a Storeman node and do not wish to participate in the second group, you must register to exit before January 31st, 2021 — in order to withdraw when the current period ends. But we highly recommended that if you do not wish to participate in the second group, you can withdraw as early as you can. If you withdraw, staked funds will be returned to your wallet on February 10th, 2021. Rewards will be issued daily as usual during the withdrawing period.Nodes who do not register to exit before the end of the current period WILL be included in the selection process for the next periodHow To Create A Storeman NodeIn general, the rewards rate of running a Storeman Node is about 50% higher than the rewards rate of being a delegator. To set up a node, users need to at least well prepare the following two things:You need to have enough WAN to stake to the Storeman node you created. Those WAN coins can be either totally contributed by yourself or partly from partners and delegators through the way of Partner In and Delegation. In short, the top 20 Storeman nodes with staking amount will finally enter to the Storeman Group.You have to buy the cloud service on AWS, Google Cloud or Ali Cloud, etc, and deploy your node on the cloud.For the detailed operations of how to set up a Storeman, please go to Wanchain 5.0 Mainnet Storeman Setup Guide.Increasing Amount of Staking Assets & Converted Assets13.45 Million WAN Staked!The total staking amount of current Storeman Group has increased significantly, from 2.2 million WAN on November 15th, 2020 to 13.45 million WAN as of January 27th, 2021.Over $3.25 million in Cross-chain AssetsThe value of cross-chain assets including wanBTC, wanETH, wanEOS, wanUSDT, wanUSDC, wanUNI, wanLINK, which now exceeds 3.25 million USD.Besides, the Ethereum-based DeFi application WanFarm will soon start its staking & mining. Stay tuned.A Major Upgrade For Wanchain’s Cross-chain Mechanism in Q1, 2021For Wanchain 5.0, there is a one-to-one correspondence between a wanBridge and a Storeman Group. Therefore, to connect any two public chains, at least one Storeman Group must be created between the two. Under this mechanism, if a Storeman node wants to participate in multiple wanBridges of connecting different public chains, the node operator must run multiple Storeman nodes in different Storeman Groups. Obviously, this situation increases the difficulty of operation for node operators. The deposit funds among different Storeman Groups are independent and cannot share the cross-chain quotas with each other. So, the utilization rate of the deposits is low, which results in the intensive economic bandwidth of busy wanBridges and wastes economic bandwidth of leisure wanBridges. Theoretically, this mechanism has a small security risk of collusion among Storeman nodes.For the reasons above, considering the efficient utilization of resources, the improvement of cross-chain security and the optimization of user convenience, the Wanchain cross-chain mechanism will undergo one more major upgrading on the basis of 5.0. It is expected that the upgraded Storeman Group mechanism will be launched in Q1 2021.Currently, the new cross-chain mechanism is being developed and tested in an orderly manner.At that time, a Storeman Group will uniformly manage all wanBridges which connect two different public chains, and the staking deposits will also serve as the common deposit for all wanBridges in the entire cross-chain network.For more details on the new generation of Wanchain’s cross-chain mechanism, please see the article Universal Multichain Bridges with Shared Staking Assets written by VP of Engineering, Dr. Zhang Weijia.About WanchainWanchain is the infrastructure connecting the decentralized financial world. Wanchain’s live cross-blockchain solution is EVM-based, includes optional private transactions, and provides a decentralized, permissionless, and secure approach for interoperability.

Подготовка среды разработки Mac OS для использования с Syntropy Stack

Время, которое вы потратите на правильную настройку вашей локальной среды разработки определенно окупится в ближайшем будущем. Это максимизирует эффективность и снизит количество повторяющихся задач в вашей рабочей деятельности. Уже сегодня я разработал несколько проектов с использованием Syntropy Stack. В большинстве случаев при первоначальной настройке таких проектов не требуется выполнять какие-либо новые действия. Здесь все однообразно, поэтому я пошагово разберу этот процесс. Вот полный список того, что мы рассмотрим:Создание токена агента в аккаунте Syntropy StackУстановка Python ≥ 3.6Установка интерфейса командной строки Syntropy и конфигурации Syntropy «Сеть как код»АутентификацияУстановка Ansible и Syntropy Ansible CollectionСоздание виртуальных машинSSH ключиСоздние токена агентаВаш токен агента — это ключ API, который вы будете использовать со своими агентами Syntropy, чтобы они могли пройти аутентификацию и присоединиться к экосистеме Syntropy. Вы можете сгенерировать токен агента с помощью пользовательского интерфейса Syntropy. Если у вас еще нет учетной записи Syntropy Stack, вы можете запросить доступ на официальном веб-сайте проекта. Как только вы войдете в систему, щелкните по выпадающему списку рядом с вашим именем пользователя и выберите Agent tokens.Создание токена агентаНажмите на кнопку[+] New Agent Token , чтобы создать свой токен. Я предпочитаю создавать по одному токену для каждого проекта. Таким образом, если ваши учетные данные каким-то образом были получены третьей стороной, вы можете уничтожить токен такого проекта, не затрагивая другие проекты, которые могут быть подключены к сети в данный момент. Не забудьте изменить дату истечения срока действия (Expiration date), поскольку по умолчанию она соответствует текущему дню, а это означает, что если вы оставите ее как есть, токен станет недействительным на следующий день.Установка Python ≥ 3.6Зависимости для консольного клиента Syntropy требуют Python не ниже версии 3.6. Mac OS по умолчанию поставляется с Python 2.7, поэтому нам может потребоваться установить Python3.Прежде чем что-либо делать, убедитесь, что у вас установленpython3:$ which python3/usr/local/bin/python3$ python3 --versionPython 3.8.5Если он не установлен, вы увидите следующее:$ python3 --version-bash: python3: command not foundМы будем устанавливать Python3 с помощью Homebrew (менеджер пакетов для Mac OS). Если у вас возникли проблемы, вам может потребоваться установить утилиты Xcode, вы можете сделать это, следуя этому руководству. Если у вас не установлен Homebrew, вы можете установить его, скопировав и вставив следующую команду в свой терминал:/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"Хорошо, теперь давайте установим Python3.brew install PythonТеперь проверим, что все установилось как надо:$ which python3usr/local/bin/python3Чтобы установить пакеты для python3 мы будем использовать pip3. Вы можете проверить версию pip3 следующим образом:$pip3 --version pip 19.3.1 from /usr/local/lib/python3.9/site-packages/pip (python 3.9)Установка интерфейса командной строки SyntropyВ основном мы будем использовать две отдельные утилиты, которые являются частью интерфейса командной строки, syntropyctl(Computational Topology Library — Библиотека вычислительной топологии) и syntropynac(Network as Code — Сеть как код). Если вам понадобится дополнительная информация, обратитесь к документации Syntropy Stack. Мы можем установить эти утилиты следующим образом:pip3 install syntropycli && pip3 install syntropynacПрежде чем вы сможете сгенерировать токен API, вам нужно добавить в SYNTROPY_API_SERVERвашу переменную среды ENV. Вы можете скопировать и вставить команду в терминал, а затем нажать return, но я рекомендую добавить ее в ~/.bashrcили ~/.zshrc(в зависимости от того, какую оболочку вы используете). Не забудьте создать исходный файл после его добавления, чтобы переменная среды ENV была доступна в вашем текущем сеансе.export SYNTROPY_API_SERVER=https://controller-prod-server.syntropystack.comАутентификацияНам нужно сгенерировать токен API, который позволяет нам аутентифицировать команды интерфейса командной строки. Не путайте токен API (формируется с использованием интерфейса командной строки) с Токеном Агента (ключ API, сгенерированный с использованием пользовательского интерфейса Syntropy).Сгенерируйте токен API, войдя в систему с помощью интерфейса командной строки:syntropyctl login <your_syntropystack_username> <your_syntropystack_password>Эта команда выведет буквенно-цифровую строку (например, ваш токен API). Скопируйте токен API, который выводит эта команда, и добавьте его в переменные среды ENV вашей системы. Я поместил свой токен в .zshrc (потому что я использую zshell вместо bash, но вы также можете разместить его в своем .bashrc). Кроме того, вам необходимо добавить имя пользователя Syntropy Stack и пароль, а также SYNTROPY_API_SERVER в переменные среды вашей системы.Отредактируйте ваш .zshrcили .bashrc. Как пример vim ~/.zshrcи добавьте к нему следующее:export SYNTROPY_API_TOKEN=”your_syntropy_api_token”export SYNTROPY_PASSWORD=”your_syntropy_password”export SYNTROPY_USERNAME=”your_syntropy_username”Не забудьте получить файл из текущего окна терминала, чтобы переменные стали доступны в ваших переменных среды ENV.source ~/.bashrcили source ~/.zshrc.Вы можете проверить переменные среды env, просто набрав envв окне терминала и нажав return.Установка Ansible и Syntropy Ansible Galaxy CollectionAnsible — это самый простой способ автоматизировать приложения и ИТ-инфраструктуру. Развертывание приложений + Управление конфигурацией + Непрерывная доставка.Мы будем использовать Ansible для настройки хостов наших виртуальных машин, установки необходимых зависимостей, развертывания наших агентов и служб, а также для создания наших сетей. Установка Ansible проста и может быть выполнена с помощью pip3диспетчера пакетов Python. У Ansible отличная документация, поэтому обязательно ознакомьтесь с ней, если вам интересно на что он способен, или если вы не уверены в том, как это работает. Мы будем использовать Syntropy Ansible Galaxy Collection. Ansible Galaxy содержит контент, созданный сообществом Ansible. Коллекции содержат пригодные для использования сценарии, роли и модули, которые мы можем включить в наши собственные сценарии.Для начала установим Ansible.pip3 install ansibleУбедитесь, что установка завершилась успешно.$ ansible --versionansible 2.10.4 configured module search path = ['/Users/craig/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules'] ansible python module location = /usr/local/lib/python3.9/site-packages/ansible executable location = /usr/local/bin/ansible python version = 3.9.1 (default, Nov 1 2019, 02:16:32) [Clang 11.0.0 (clang-1100.0.33.8)]Следующее, что необходимо сделать, это создать глобальный файл конфигурации, чтобы упростить чтение журнала, выводимого из интерфейса командной строки Ansible. Создайте файл конфигурации Ansible и поместите его в ваш домашний каталог.$ vim ~/.ansible.cfgДобавьте к нему следующее (убедитесь, что ansible_python_interpreterустановлен на результат вывода вашей команды which python3 ):[defaults]stdout_callback=yaml# use stdout_callback when running adhoc commands toobin_ansible_callbacks = Trueinterpreter_python = auto_silentremote_tmp = /tmp/ansible-$USERansible_python_interpreter = usr/local/bin/python3Вывод журнала без настроек конфигурации выглядит следующим образом:TASK [create_docker_network : Create Docker network] *****************************************************************ok: [broker] => {"ansible_facts": {"docker_network": {"Attachable": false, "ConfigFrom": {"Network": ""}, "ConfigOnly": false, "Containers": {"1893dcb898d5299c5dd9cf5a2219f2e2f08956507afc56d86bfe64cb96e18837": {"EndpointID": "7b9ec7d78666c965795c34db03465562e4bb7f5bdfa21de71d5f69824c3b48a7", "IPv4Address": "172.20.0.2/24", "IPv6Address": "", "MacAddress": "02:42:ac:14:00:02", "Name": "mosquitto"}}, "Created": "2021-01-11T17:10:29.613448381Z", "Driver": "bridge", "EnableIPv6": false, "IPAM": {"Config": [{"Subnet": "172.20.0.0/24"}], "Driver": "default", "Options": null}, "Id": "9e6daec0c1bb385fc2d6459655602ab5ce127505e7e6eaea091c9e5af7b5a1f0", "Ingress": false, "Internal": false, "Labels": {}, "Name": "syntropynet", "Options": {}, "Scope": "local"}}, "changed": false, "network": {"Attachable": false, "ConfigFrom": {"Network": ""}, "ConfigOnly": false, "Containers": {"1893dcb898d5299c5dd9cf5a2219f2e2f08956507afc56d86bfe64cb96e18837": {"EndpointID": "7b9ec7d78666c965795c34db03465562e4bb7f5bdfa21de71d5f69824c3b48a7", "IPv4Address": "172.20.0.2/24", "IPv6Address": "", "MacAddress": "02:42:ac:14:00:02", "Name": "mosquitto"}}, "Created": "2021-01-11T17:10:29.613448381Z", "Driver": "bridge", "EnableIPv6": false, "IPAM": {"Config": [{"Subnet": "172.20.0.0/24"}], "Driver": "default", "Options": null}, "Id": "9e6daec0c1bb385fc2d6459655602ab5ce127505e7e6eaea091c9e5af7b5a1f0", "Ingress": false, "Internal": false, "Labels": {}, "Name": "syntropynet", "Options": {}, "Scope": "local"}}После добавления настроек конфигурации он будет выглядеть следующим образом:TASK [create_docker_network : Create Docker network] *****************************************************************ok: [broker] => changed=false ansible_facts: docker_network: Attachable: false ConfigFrom: Network: '' ConfigOnly: false Containers: 1893dcb898d5299c5dd9cf5a2219f2e2f08956507afc56d86bfe64cb96e18837: EndpointID: 7b9ec7d78666c965795c34db03465562e4bb7f5bdfa21de71d5f69824c3b48a7 IPv4Address: 172.20.0.2/24 IPv6Address: '' MacAddress: 02:42:ac:14:00:02 Name: mosquitto Created: '2021-01-11T17:10:29.613448381Z' Driver: bridge EnableIPv6: false IPAM: Config: - Subnet: 172.20.0.0/24 Driver: default Options: null Id: 9e6daec0c1bb385fc2d6459655602ab5ce127505e7e6eaea091c9e5af7b5a1f0 Ingress: false Internal: false Labels: {} Name: syntropynet Options: {} Scope: local network: Attachable: false ConfigFrom: Network: '' ConfigOnly: false Containers: 1893dcb898d5299c5dd9cf5a2219f2e2f08956507afc56d86bfe64cb96e18837: EndpointID: 7b9ec7d78666c965795c34db03465562e4bb7f5bdfa21de71d5f69824c3b48a7 IPv4Address: 172.20.0.2/24 IPv6Address: '' MacAddress: 02:42:ac:14:00:02 Name: mosquitto Created: '2021-01-11T17:10:29.613448381Z' Driver: bridge EnableIPv6: false IPAM: Config: - Subnet: 172.20.0.0/24 Driver: default Options: null Id: 9e6daec0c1bb385fc2d6459655602ab5ce127505e7e6eaea091c9e5af7b5a1f0 Ingress: false Internal: false Labels: {} Name: syntropynet Options: {} Scope: localЭто вызывает гораздо меньше беспокойства! Помещая файл .ansible.cfg в домашний каталог ( ~/), вы делаете его глобальным. Вы можете поместить дополнительный файл .ansible.cfg в корень вашего проекта, и он переопределит любые настройки, которые перекрываются с глобальной конфигурацией.Далее установим galaxy collection:ansible-galaxy collection install git@github.com:SyntropyNet/syntropy-ansible-collection.gitПерейдите в локальный каталог ansible, например в Mac OS:cd /Users/{user}/.ansible/collections/ansible_collections/syntropynet/syntropyУстановите зависимости Python.pip3 install -U -r requirements.txtСоздание виртуальных машинКаждой запущенной виртуальной машине желательно находиться в инфраструктуре отдельного облачного провайдера. Вы можете использовать любого облачного провайдера, который в настоящее время поддерживается Syntropy Stack. Ознакомьтесь с официальной документацией для получения полного списка провайдеров. Использование различных провайдеров не является обязательным требованием, но мы делаем это, чтобы продемонстрировать гибкость, совместимость и простоту использования при работе с Syntropy Stack на просторах Интернета. Итак, если вы не хотите использовать трех отдельных облачных провайдеров, попробуйте разместить ваши виртуальные машины в разных географических регионах. Самое главное, чтобы ваши виртуальные машины не использовали общедоступный IP-адрес. У меня есть 3 базовых виртуальных машины от Digital Ocean, GCP и AWS. Я использовал этих провайдеров, так как у меня уже есть там учетные записи и я знаком с их услугами. Я настроил свои виртуальные машины следующим образом:FluentD: Digital Ocean, Тип: Базовый, 1vCPU, память: 1 ГБ, ОС: Ubuntu 20.04Elasticsearch: Google Cloud Platform, Тип: e2-micro, 2vCPU, память: 1GB, ОС: Ubuntu 20.04Kibana: AWS, Тип: t2-micro, 1vCPU, память: 1 ГБ, ОС: Ubuntu 18.04Все три варианта находятся в одном ценовом диапазоне (около 5–6 долларов в месяц) и их достаточно для целей данного примера.Настройка каждой виртуальной машины на конкретном облачном провайдере выходит за рамки этого поста, но я разместил ниже несколько ссылок на руководства, чтобы вы смогли с чего-то начать, если не знаете, как приступить к созданию виртуальных машин. Вам нужно будет добавить свой открытый ключ SSH, чтобы вы могли получить доступ к виртуальным машинам из терминала с помощью SSH. Я бы рекомендовал установить Ubuntu в качестве вашей операционной системы, чтобы вы могли просто скопировать и вставить команды, которыми я делюсь. Конечно же, если вам комфортно работать в других версиях Linux, то, безусловно, вы можете работать и в них. Факт того, что Syntropy Stack использует docker, означает, что мы не зависимы от дистрибутива!Creating an AWS EC2 instanceQuickstart using a Linux VM | Compute Engine DocumentationHow to Create a Droplet from the DigitalOcean Control Panel | DigitalOcean Product DocumentationQuickstart - Create a Linux VM in the Azure portal - Azure Virtual MachinesSSH ключиЛично я предпочитаю создавать отдельные пары ключей SSH для разных проектов или задач, в зависимости от области применения. Например, у меня есть выделенная пара ключей syntropy_rsa, которую я использую со всеми своими виртуальными машинами Syntropy.Если вы хотите создать новую пару ключей, вы можете использовать следующую команду. Флаг -N просто создает пару ключей без ключевой фразы, что полезно для некоторых автоматизированных задач (например для рабочих процессов GitHub). "user@host"– это всего лишь способ определения пары ключей. Вы можете использовать что-то вроде syntropy@local.$ ssh-keygen -t rsa -b 4096 -C "user@host" -q -N ""Enter file in which to save the key (/Users/craig/.ssh/id_rsa): /Users/<user>/.ssh/syntropy_rsaДалее авторизуем этот новый ключ на виртуальных машинах. Добавьте ваш новый открытый ключ в каждый из authorized_keys файлов вашего хоста. Вы можете сделать это из командной строки вашего локального компьютера для разработки. <host>будет публичным IP-адресом вашей виртуальной машины, а <user> — именем пользователя Linux для этой виртуальной машины. Например, в AWS пользователь EC2 по умолчанию — это всегда ubuntu.Напримерssh-copy-id -i ~/.ssh/syntropy_rsa.pub <user>@<host> -fВы также можете сделать это вручную, если у вас нет ssh-copy-id. Просто подключитесь к своей виртуальной машине по SSH и добавьте открытый ключ в файл ~/.ssh/authorized_keys. Вы можете скопировать открытый ключ в буфер обмена следующим образом:pbcopy < ~/.ssh/syntropy_rsaПросто имейте в виду, что в зависимости от вашего облачного провайдера вам, вероятно, придется добавлять открытый ключ SSH через их пользовательский интерфейс/консоль, прежде чем у вас будет доступ по SSH. Например, в Digital Ocean открытый ключ добавляется через Settings > Security.Добавление открытого ключа SSH в Digital OceanПоследнее, что вам может потребоваться проверить, это то, что порт 22 открыт для входящего трафика. Опять же, в зависимости от вашего облачного провайдера, вам, возможно, придется установить его вручную или настроить брандмауэр, чтобы разрешить входящий трафик на порт 22. Далее пример настройки моего сетевого брандмауэра облачного провайдера Digtial Ocean в разделе Networking > Firewalls > Rules.Настройка правил для входящего трафика в брэндмауэре облачного провайдера Digital OceanБонусКто-то из тех, кто смотрел запись моего экрана, спросил о моей IDE и настройке терминала. Я использую iTerm2 как замену своему терминалу Mac OS, а также zshell в качестве оболочки по умолчанию. В iTerm2 я используя цветовую тему Google Material Design от Мартина Зилера (ссылка ниже).MartinSeeler/iterm2-material-designЧто касается IDE, то существует множество IDE для разработки, но на мой взгляд код Microsoft Visual Studio, безусловно, лучший.Visual Studio Code - Code Editing.

Announcing VeChain Sync 2 — Unlocking Revolution For The Entire Blockchain dApp Industry, Enabling…

Announcing VeChain Sync 2 — Unlocking Revolution For The Entire Blockchain dApp Industry, Enabling Seamless User Experience Across All PlatformsToday, almost all internet users are familiar with the concept of web-based applications, whether email, e-commerce or teleconference platform. Thanks to the development of modern web browsers, web applications are readily and easily accessible across multiple platforms, irrespective of OS or device type.Blockchain dApps, however, are not so simple. Using dApps can often prove restrictive, forcing users to choose specific browsers to access certain wallets. Users may also have to switch wallet apps depending on whether they’re using a desktop or mobile device, resulting in an inconsistent user experience. Furthermore, dApp users have to manage crypto assets, pay gas fees and carry a certain level of technical expertise to use decentralised platforms. The complexity, cost and awkwardness of current dApp infrastructure severely hinders their potential for mass adoption.Sync 2, our newly developed digital wallet app, in tandem with key protocols such as VIP-191 (fee delegation) and VIP-201 (DaaS) provide the missing pieces of critical infrastructure in enabling the true mass adoption of dApp technology.With Sync 2, users are no longer restricted by browser type, mobile or PC usage. Using dApps becomes as simple and intuitive as any other web-based application. In combination with VeChain’s native fee delegation protocols, users will no longer need to manage crypto to pay gas fees. Instead, dApp owners or DaaS service providers can fund gas fees on a user’s behalf.Put simply — Sync 2 is the missing jigsaw piece that enables a truly seamless dApp experience, paving the way for the mass adoption of decentralised applications by removing all barriers to entry. A first for the entire blockchain industry.Announcing Sync 2Sync 2 is the brand new digital wallet developed by VeChain’s blockchain team. It is designed to address the above problems and accelerate the mass adoption of dApps built on the VeChainThor public blockchain by creating a truly seamless user experience irrespective of OS or device:Sync 2 is designed to work with all mainstream web browsers (e.g., Chrome, Safari, MS Edge, Firefox, etc), allowing dApps to be accessed by ever-greater numbers of usersIt can be installed as a local app on your desktop or mobile device, or used simply as a web application with no installation requirement, providing maximal flexibility and consistent user experienceHow Sync 2 LooksThe following animation illustrates how Sync 2 may interact with dApps in practice. Whenever a dApp requests its user to sign a transaction, it will automatically invoke the Sync 2 wallet app to pop up from the background and let the user sign the transaction.Note that if the dApp does not find the existence of a local Sync 2 app, it will try to run Sync 2 as a web application, or more specifically, a single page application (SPA). Simply speaking, there will be a pop-up web page that loads and runs Sync 2 right away.With Sync 2, user experience becomes as simple and intuitive as any traditional web application.Opening Up Seamless dApp Usage Across All PlatformsThe main advantage and purpose of Sync 2 is the massive simplification of dApps and dApp usage. All editions of Sync 2, no matter whether the native app built for desktop or mobile, or the automatically invoked SPA version, are designed to appear and function pretty much in the same way, therefore providing a consistent and comfortable user experience for users across different OS and devices. For instance, if a dApp is built around Sync 2 and is mobile friendly, users can use the web browser installed on their mobiles to access the dApp and have a similar user experience as they would on a desktop.Connex 2: Javascript Library for dApps to Interact with Sync 2Besides the superior user experiences Sync 2 is going to bring to us, the VeChain’s blockchain team is also releasing the Connex 2 JavaScript library to make it highly efficient for developers to integrate their dApps with Sync 2.Connex 2 provides APIs for developers to interact with VeChainThor. Moreover, it provides an efficient way for developers to utilize VeChainThor’s unique features such as the multi-task transaction (MTT) and fee delegation protocolsIt allows dApps to invoke Sync 2 through a simple API callIt implements the VIP-201 protocol, paying the way for dApps to adopt the VIP-191 fee delegation serviceIt is designed to be backward compatible with the previous Sync desktop wallet app, allowing existing dApps to upgrade from previous versions of Connex to Connex 2 without affecting their current usersAs an example, the lead developer of Sync 2, Bin Qian, shows how to build up a dApp using Connex 2 and Sync 2 with just a few dozen lines of code.Alpha Testing for Developers Open NowStarting today, the VeChain Core Dev team has publicized the codebase of Sync 2 and Connex 2.Please note: Both Sync 2 and Connex 2 are still in the alpha testing stage and should strictly be used for development purposes only, and are not recommended to be used in a production environment to handle live digital assets. The Beta version for general users approximately will be available in Q2 2021.In addition, if you are not a developer, it is NOT RECOMMENDED to be used as your daily wallet and fund management tool. Please refrain from using it — VeChain will not be held responsible for any losses for your digital assets in the event of any bugs or glitches.To experience how Sync 2 interacts with dApps, please visit https://lite.sync.vecha.in/#/, you can also try the faucet app deployed on the testnet and begin experimenting.

$DIGG, 3x Bitcoin Price, What Is It? How Can You Earn It Through Mining?

What token is the most expensive token in the crypto world? BTC? YFI? ALL NO! It is DIGG which just goes live for 4 days. Starting at $51,194, $DIGG soared to $93,637 ATH, which is 3 times of $BTC price.(Source: Coingecko)After weeks of anticipation and a closely-watched series of preparatory steps, BadgerDAO’s synthetic rebasing Bitcoin, $DIGG, is now live and claimable for qualified addresses on Ethereum mainnet.We introduced BadgerDAO, $badger and $DIGG in this article Badger= BTC + AMPL + YFI? Bring Bitcoin into DeFi! on 7th Dec. At that time, $BADGER price is just $3, now it is $16. At that time, $DIGG has not lived yet, but we have introduced to you that DIGG is a very important part of BadgerDAO. Those users who have read our article about BadgerDAO before and used it once must be very happy because you guys all got $DIGG airdrop!What is $DIGG?$DIGG is the synthetic rebasing Bitcoin issued by BadgerDAO. It’s an elastic supply cryptocurrency that’s pegged to the price of Bitcoin.How does $DIGG peg with Bitcoin?There are 2 parts of the mechanism that made the $DIGG pegged to Bitcoin.$DIGG distribution for Sett holders$DIGG elastic supply mechanism to adjust the supplyLet’s look at the first part — $DIGG distribution for Sett holders first.There are 2 Setts in BadgerDAO, Digg Sett and Badger Sett. (What’s $Badger?)The green box is the Badger Sett; the Yellow box is the Digg Sett.When DIGG price is at the peg, 50% of DIGG emissions go to DIGG Setts, and 50% go to Badger Setts.If DIGG is at 80% of BTC price or below it, all DIGG emissions go to the DIGG Setts.If DIGG price is at 130% of BTC price or above it, 70% of DIGG emissions go to Badger Setts and 30% to DIGG Setts.The $DIGG will be pegged to Bitcoin due to the below assumptions.Incentivizes DIGG holders to LP and Stake when the price is below peg. The higher APYs for DIGG Setts also create the necessary demand for DIGG to move its price closer to peg.Motivates Badger Setts users to support the price of DIGG, as it allows them to receive larger rewards.Incentivizes DIGG LPs and stakers to move the price lower when it’s above peg to receive a larger % of DIGG emissions.Second part — $DIGG elastic supply mechanism to adjust the supply.Rebasing is the mechanism that adjusts the supply of an elastic supply asset to promote price stability. Rebase period is every 24h.DIGG is currently pegged to 1 BTC, and uses a custom oracle to determine the necessary change in supply.If DIGG price is above 1.05 BTC, DIGG supply increases. This is known as a positive rebase.If DIGG price is below 0.95 BTC, DIGG supply decreases. This is known as a negative rebase.If DIGG price is between 0.95 and 1.05 BTC, DIGG does not rebase.Every DIGG holder gets the same increase or decrease in supply every rebase. However, this increase or decrease is offset by the subsequent increase or decrease in price.Currently, $DIGG has completed 2 rounds of rebase.Round 1 = Positive Rebase of 120.145%. This equates to a 12.01% increase today across the entire supply.Round 2 = Positive Rebase of 142.6%. This equates to a 14.26% increase today across the entire supply.How Can You Participate in the $DIGG Mining?Currently, 600 $DIGG has been airdropped to BadgerDAO users. Congrats if you follow us and use BagerDAO before! Check your wallet to claim the $DIGG airdrop!If you fail to catch the earliest chance, don’t worry. You can still participate in the $DIGG mining through the Digg Sett and Badger Sett.For Digg Sett holders, your profit contains 3 parts:$DIGG distribution for Digg Sett holdersSushiswap/Uniswap Digg LP token liquidity supply profit$DIGG rebase profitFor Badger Sett holders, your profit contains 4 parts:$DIGG distribution for Badger Sett holders$Badger Sett mining profitSushiswap/Uniswap Badger LP token liquidity supply profit$DIGG rebase profitYou can choose the Sett you want, stake in the pool and start your mining.The green box is the Badger Sett; The yellow box is the Digg Sett.No $BADGER or $DIGG to start? You can buy $BADGER in Huobi (centralized exchange) or Uniswap and Sushiswap (DEX). For $DIGG, you can only attain it in Uniswap or Sushiswap for now.What Will Happen to BadgerDAO and $BADGER?Now you must have understood that there are 2 tokens in BadgerDAO — $BADGER serves as its platform governance token and $DIGG serves as its Bitcoin pegged token.The black spot line indicates the $BADGER token priceLook at the social signal, it has started to increase since 26th Dec because of the intense discussion of WEN/When will $DIGG goes live.Social signal indicates the level that the project/token is being discussed in social network. You can see the high correlation between BadgerDAO social signal and its token price.And the expectation for the launch of $DIGG has driven up BadgerDAO on-chain active users amount and transaction amount to a daily ATH at 1.43k daily active users and 2.4k daily transactions. You can see the same growth trend of BadgerDAO on-chain data and $BADGER token price.Social signal and on-chain data reflect what extent people are discussing and joining the project.

Loopring 01.27

LRC Tokenomics v2

The Loopring protocol token, LRC, has been part of the protocol since our inception over 3 years ago. It's design and usage have remained largely the same over this time, while the protocol and products have made profoundly important progress. It is time the LRC model pulls itself up to keep pace with — and enhance — the Loopring protocol and product suite.LRC will be used to incentivize behavior that is beneficial for the Loopring ecosystem, have a say in said system, and further ignite the transition to Ethereum L2.TLDRLoopring protocol fees come from transaction volume (economic activities) on Loopring Layer-2 (L2) and are also distributed on L2.The initial protocol fee parameter will be set to 20% of the L2 transaction fee. With the current relayer settings, this means 2 bps (0.02%) for AMM swaps, between 0.8 bps to 4.6 bps (0.008% to 0.046%) for orderbook trades, and $0.01 for transfers.Protocol fees are paid to 3 types of participants: a) liquidity providers, b) insurers, c) Loopring DAO, in an 80/10/10 proportion, respectively.Protocol fees accrued in tokens other than LRC and ETH will be sold on our L2 for LRC and/or ETH; all protocol fees are distributed in LRC and/or ETH.Protocol fees will be paid on a monthly basis.Changes to parameters in the future will go through a forthcoming Loopring DAO.Whereas in the prior protocol version (v3.1) protocol fees went to LRC stakers who locked up tokens for a minimum of 90 days, the new token model rewards LRC holders who use their assets productively for the good of the platform. LRC will be used to incentivize behavior that helps the entire protocol.Protocol fee distribution is configurable by the forthcoming Loopring DAO, but will initially be distributed to participants in the following manner:80% to liquidity providers (LPs) on Loopring orderbooks and AMM. At least 50% of this portion goes to LRC related liquidity.10% to insurers — users who put capital into a safety insurance fund.10% to Loopring DAO — the DAO decides how to spend these funds: buyback and burn, impermanent loss protection, further liquidity incentives, grants, etc.These proportions are configurable by the forthcoming Loopring DAOThese Loopring ecosystem participants collectively act to support and strengthen the Layer-2 network, and for their work, they are rewarded.For the first time on Ethereum, protocol fees are earned and distributed on Layer-2. This represents a significant UX improvement, as it means no wasting money (gas) and time entering staking contracts on L1, nor claiming your rewards. They will be sent to their rightful recipients’ Loopring L2 accounts automatically at the end of every month. [All sub-dollar amounts will not be paid nor accumulated.]A word on Loopring L2 fees in generalLoopring is a zkRollup protocol — a type of secure Layer-2 scaling solution for Ethereum. On a zkRollup, there are no gas fees that can swing wildly. There are ‘normal’ style fees: i.e., a small percentage fee to do a trade or swap, or a small flat fee to do a transfer or withdrawal. These are less dependent on gas prices, so users have a smoother experience, never paying massive surges, and never waiting for confirmations when the network is congested — settlement is instant on the L2.We call these L2 transaction fees.These fees are paid to the operator of the zkRollup, something we often refer to as the Loopring relayer. The relayer is the entity that makes a zkRollup run — it hosts the Merkle tree, creates roll-up blocks, generates the zkSNARK proofs to publish to Ethereum, etc. The relayer must earn fees, as it has significant, ‘legacy world’ and ‘Ethereum world’ costs: compute power for generating the proofs, and gas costs for publishing the blocks to Ethereum, respectively.The L2 fee settings referenced in this article are the current settings, but should not be considered permanent. Loopring relayer must decide the fees based on various factors (activity on the zkRollup, compute cost, gas prices on Ethereum, etc.) and adjust them when necessary.Protocol feesFrom the L2 transaction fees comes the protocol fee. The protocol fee is described as 20% of the L2 transaction fee. That is, 20% of the fee that the relayer charges on every trade and transfer go to LRC liquidity providers, insurers, and voters who participate in the success of the Loopring L2.AMMThere is a 0.25% fee for swaps done on Loopring’s L2 AMM as it stands. Again, please note this is ‘all-in’; there is no gas fee.0.15% of this fee goes to liquidity providers (LPs) for the relevant pool. These are the people who provide the assets in the pool, for users to swap against.0.1% is the L2 transaction fee, paid to the Loopring relayer so the zkRollup can run.It is from this L2 fee of 0.1% that the protocol fee is paid. So, 0.1%*20% protocol percentage = 0.02% (2 bps) protocol fee from AMM swaps.Since LPs earn the 0.15% liquidity fee, plus a portion of the protocol fees, you can see that LPs actually earn >0.15% of their pools’ L2 volume.OrderbookTrading fees on the orderbook follow a maker-taker model.Taker fees are 0.25% (or lower for VIP tiers). Takers are users who take liquidity from the orderbook (they are filled immediately).Maker fees are -0.02% (negative 2 bps). Makers are users who add liquidity to the orderbook (their orders rest on the book for some time). Makers earn rebates to pay them for their service of providing liquidity, just like LPs earn in the AMM pools. Makers earn 2 bps (0.02%) on all of their filled orders.On stablecoin vs stablecoin pairs, taker fee is 0.04%, and maker fee is still -0.02%.Protocol fees are once again 20% of the L2 fee (removing the liquidity incentive for makers first). So, (0.25%-0.02%)*20% protocol percentage = 0.046% (4.6bps) protocol fee from orderbook trading [and 0.004% (0.4bps) on stablecoin-stablecoin orderbook trading].Once again, since makers, like AMM LPs, earn a portion of the protocol fees, you can see that makers effectively earn more than the 4.6bps rebates of their L2 volume.Note: in both AMM and orderbook trading, there are users who have VIP level status. This means they have a lower trading fee (<0.1% to relayer in AMM, and <0.25% to relayer in orderbook). Since VIPs pay less in L2 fees, that means protocol fees (calculated as L2 fees * 20%) would be commensurately lower on those trades. In other words, protocol fee is always calculated from the ‘final figure’, the amount flowing to the relayer.TransfersThere are small fixed fees for L2 transfers for users, currently $0.05. The protocol fee is once again 20% of the amount charged by the relayer, so 1 cent.Summary — the current fees earned by the protocol are 0.02% on AMM swaps, 0.046% on orderbook trades, 0.004% on stablecoin-stablecoin trades, and $0.01 on transfers.The image below depicts the protocol fees from L2 transaction types:How fees are split from Loopring L2 transaction typesIf traders on the AMM or Normal Orderbooks had a VIP tier (stablecoin pairs have no VIP, always 0.04% fee), the absolute figures above would be reduced, but the proportions remain the same. For a look at the overall fee structures on Loopring Exchange & Wallet, please see here, but recognize this is not final, and may change.Just recall that the protocol fee is always 20% of the amount flowing to the relayer. The first thing we do in any fee scenario is remove the piece that goes to liquidity providers (the orange piece of the pies). Of the remaining fees — what we called the L2 fees — 20% goes to protocol fee, 20% to affiliates (referrers or applications that send users & volume to Loopring L2), and the remaining 60% to the relayer. Stay tuned in another post for the coming affiliate program.Note: the protocol fee percentage can be between 5% to 20% of the L2 transaction fee. We have set it at its upper limit of 20% to start. The Loopring DAO will manage this going forward.Recipients of the Loopring protocol feeAs mentioned, protocol fees are earned by liquidity providers, insurers, and the DAO. Let’s learn a bit more about each.Liquidity Providers80% of the protocol fee goes to LPs in AMM pools and makers on orderbook pairs.At least half of this amount goes to LRC related trading pools and pairs. i.e., LPs/makers of LRC-ETH, LRC-USDT, etc., earn 1/2 of the 80% slotted for LPs, effectively 40% of all protocol fees.Loopring recently announced L2 liquidity mining, the second round of which is currently live. It is through this liquidity mining mechanism that protocol fees will be paid to liquidity providers.That means Loopring will be incentivizing LPs of certain pools with funds from the foundation’s treasury, as well as from protocol fees that are generated. The rewards you see in the articles linked above are from Loopring incentive treasury itself, while in the future, they will come from both treasury and fees. You can think of this as one bucket, since all these incentives go to LPs/makers. But in the long term, it is only sustainable that liquidity incentives will be coming from fees generated by protocol activity.InsurersThe Loopring zkRollup, like all zkRollups, are secured by Ethereum and Zero-Knowledge cryptography (validity proofs). There is no need for novel consensus mechanisms, and no new validators to trust. Ethereum simply existing and the cryptographic techniques being sound is all you need to rely on. You don’t need to trust Loopring or anyone else at all for the security of your assets. A zkRollup is 100% non-custodial.All that said, unforeseen bugs are a possibility in any software. In a zkRollup, this would mean some bug in the Loopring smart contracts. While our v3.6 smart contracts have been audited and currently hold approximately 130 million USD worth of assets, that does not mean the risk is non-existent. And given we expect a Loopring L2 economy hosting several billions of dollars worth of assets, a security fund is important.For this reason, we are creating a Loopring insurance fund. Users can deposit LRC into the insurance fund and earn a return on their assets for providing this security backstop. 10% of all protocol fees will go to reward insurers.The insurance fund will exist on L1, since it would not make sense to provide the insurance fund on the L2 that the insurance is set to protect. Rewards accrue to the insurance fund directly, with each insurer’s claim of the pie growing. Thus, insurance is a case where protocol fees are earned on L1, not L2.Our insurance fund will be based on Aave’s safety module, since those contracts are battle-tested, and serve the purpose perfectly. The insurance coverage period will be 14 days. That means the insurer’s LRC will be locked for 14 days in order to earn the corresponding return. Voting of whether a covered incident took place or not will be 3 days (by the DAO, see next section).Stay tuned for more details on the insurance fund, which is set to go live in Q2.Loopring DAOAs Loopring has made tremendous technical progress throughout the years, it has also cultivated an amazing community. And while the Loopring foundation engineers are the ones who predominantly built the protocol and products, it will become more powerful if guided by the Loopring community.The Loopring DAO is set to launch in Q3, and it will be receiving 10% of all protocol fees. What it does with those funds is up to the DAO members (LRC holders) to decide via voting. It can buyback LRC and burn it, use for impermanent loss protection to draw more LPs, distribute to DAO voters, distribute more incentives to LPs/makers, fund grants, etc.LRC token voting will be using Snapshot, a token voting tool that suits the purposes perfectly.It will be interesting to watch the first DAO for a zkRollup protocol take shape. L2 presents many possibilities for DAOs, but also some challenges. The DAO will control and govern several parameters, such as:The distribution proportions of protocol fees to different participantsWhat it does with its own proportion of the fundsThe protocol fee percentage (between 5% to 20% of relayer fee)Insurance fund covered event triggersStill, of course, much of a zkRollup is by definition off-chain, and this means is outside the purview of a DAO (or at least outside the purview in a controlling manner, but can be used to verifiably signal). The relayer is controlled by Loopring, not executable by a DAO. [Note: the relayer can never harm or mishandle user assets, that’s the vital property of a zkRollup].We want to be completely forthcoming about the following facts.Since protocol fees are collected by the relayer on L2 and then paid out according to the methods described in this post (and ultimately by the methods decided by the DAO), there is a level of faith involved in how the relayer will reward these protocol fees. Note: distributions are 100% verifiable on-chain — a crucial property of a rollup — so there is zero possibility of any tricks.Certain parameters are simply unable to be controlled by the DAO for practical reasons. For instance, the L2 transaction fee itself must be set by Loopring, which has a handle on the legacy and Ethereum-based costs of running the relayer.It will be a great endeavor of collaboration between LRC holders/Loopring DAO, and the Loopring relayer that does the off-chain work, and ultimately execute the DAO’s wishes. This is like a legislative and executive branch. In the end, they must work together for a thriving system.TimingThis new LRC model and the corresponding protocol fees will begin immediately, and will actually have accrued retroactively since the launch of Loopring protocol 3.6 (on which Loopring Exchange v2 and the Loopring wallet are based). That date is November 27th. The calculations will take into account all fees since then, but please note that some transaction types didn’t have any fees at instantiation (such as transfers). While the protocol fees and the relative proportions to LPs, Insurers, and DAO will contain all fees since late November, we won’t begin the first distribution of these fees until March 31st. Until then, they will just accumulate for their respective buckets. After then, protocol fees will be distributed on a monthly basis to all participants. If are still in the ‘old’ LRC staking contract (v1) and have questions, please read this post about its sunsetting.We are extremely excited about this LRC model and what it means for Loopring. We have focused on research and development in engineering for so long, and now that our L2 (and L2 at large) is picking up steam, and our products are in the hands of thousands of users, it is time for the LRC economics to play its part. Ethereum L2s are largely regarded to be the environments where users will ‘live’ and transact. They are economies secured by Ethereum. Loopring was the first rollup, is currently the most voluminous and populated, and now LRC will take its rightful position in the centre of the economy and governance structure.We very much welcome your feedback, and for you to join the community in our Discord.About LoopringLoopring is an Ethereum zkRollup protocol for scalable, secure exchanges & payments.

Preparing your Mac OS dev environment for use with the Syntropy Stack

Taking the time to properly set up your local dev environment pays dividends down the road. It maximizes efficiency and reduces the number of repetitive tasks you need to perform . I’ve now built several projects using the Syntropy Stack, most of which share the same initial setup, so I’ll go through the steps for getting yourself squared away. Here’s a list of what we’ll cover:Creating an agent token through your Syntropy Stack accountInstalling Python ≥ 3.6Installing Syntropy CLI & Syntropy NACAuthenticationInstalling Ansible and the Syntropy Ansible CollectionCreating Virtual MachinesSSH KeysCreate an Agent TokenYour Agent Token is the API key you’ll use with your Syntropy Agents so that they can authenticate and join the Syntropy Ecosystem. You can generate an Agent Token using the Syntropy UI. If you’d don’t already have a Syntropy Stack account, you can request access via their website. Once you’re able to login, click the dropdown next to your username and select Agent tokens.Creating your Agent TokenClick [+] New Agent Token to create your token. I like to create one token per project. This way, if your credentials are somehow leaked, you can destroy that project token without it affecting any other networks that might be online. Remember to change the Expiration date as it defaults to the current day, meaning that if you leave it as is, the token will be invalid the following day.Installing Python ≥ 3.6The dependencies for the Syntropy CLI require a minimum Python version of 3.6. Mac OS comes with Python 2.7 out of the box, so we may need to install Python3.Before doing anything, check that you have python3 installed:$ which python3/usr/local/bin/python3$ python3 --versionPython 3.8.5If it’s not installed, you’ll see this:$ python3 --version-bash: python3: command not foundWe’ll be installing Python3 using Homebrew (a package manager for Mac OS). If you find yourself experiencing problems, you may need to install Xcode utilities, you can do so following this guide. If you don’t have Homebrew installed, you can install it by copying and pasting the following command into your terminal:/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"Okay, now let’s install Python3.brew install PythonNow try:$ which python3usr/local/bin/python3To install packages for python3, we’ll use pip3 . You can check the version of pip3 if you want to see it.$pip3 --version pip 19.3.1 from /usr/local/lib/python3.9/site-packages/pip (python 3.9)Installing the Syntropy CLIWe’ll mostly be using two separate utilities that form part of the CLI, syntropyctl (Computational Topology Library) and syntropynac (Network As Code) utilities. There’s more information in the Syntropy Stack documentation should you need it. We can install them using:pip3 install syntropycli && pip3 install syntropynacAuthenticationWe need to generate an API token that allows us to authenticate our CLI commands. Doesn’t confuse the API Token (generated using the CLI) with the Agent Token (An API key generated using the Syntropy UI).Generate an API Token by logging in using the CLI:syntropyctl login <your_syntropystack_username> <your_syntropystack_password>This command will output an alphanumeric string (ie. your API token). Copy the API token this command outputs and add it to your system’s ENV variables. I’ve placed mine in my .zshrc.(because I use zshell over bash, but you can also place it in your .bashrc. Additionally, you’ll need to add the API URL, as well as your username in password, to your system’s environment variables.Edit your .zshrc or .bashrc . Eg. vim ~/.zshrc and add the following to it:export SYNTROPY_API_SERVER=https://controller-prod-server.syntropystack.comexport SYNTROPY_API_TOKEN=”your_syntropy_api_token”export SYNTROPY_PASSWORD=”your_syntropy_password”export SYNTROPY_USERNAME=”your_syntropy_username”Remember to source the file from your current terminal window so that the variables are available in your ENV.source ~/.bashrc or source ~/.zshrc .You can check your env variables by simply typing env in your terminal window and hitting return .Installing Ansible and the Syntropy Ansible Galaxy CollectionAnsible is the simplest way to automate apps and IT infrastructure. Application Deployment + Configuration Management + Continuous Delivery.We’ll use Ansible to configure our host VMs, install necessary dependencies, deploy our agents and services, and even create our networks. Installing Ansible is simple and can be done using Python’s pip3 package manager. Ansible has great documentation, so definitely check it out if you’re curious about what it’s capable of, or if you aren’t sure about what something’s doing. We’ll be using the Syntropy Ansible Galaxy Collection. Ansible Galaxy houses content created by the Ansible community. Collections contain useful playbooks, roles and modules for us to include in our own playbooks.First, let’s install Ansible.pip3 install ansibleCheck that the installation completed successfully.$ ansible --versionansible 2.10.4 configured module search path = ['/Users/craig/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules'] ansible python module location = /usr/local/lib/python3.9/site-packages/ansible executable location = /usr/local/bin/ansible python version = 3.9.1 (default, Nov 1 2019, 02:16:32) [Clang 11.0.0 (clang-1100.0.33.8)]The next thing we want to do is create a global config file. To make the log output from your Ansible CLI easier to read, create an Ansible config file and place it in your home directory.$ vim ~/.ansible.cfgAnd add the following to it (make sure the ansible_python_interpreter is set to the result of your which python3 command output):[defaults]stdout_callback=yaml# use stdout_callback when running adhoc commands toobin_ansible_callbacks = Trueinterpreter_python = auto_silentremote_tmp = /tmp/ansible-$USERansible_python_interpreter = usr/local/bin/python3Without the config, your log output looks like this:TASK [create_docker_network : Create Docker network] *****************************************************************ok: [broker] => {"ansible_facts": {"docker_network": {"Attachable": false, "ConfigFrom": {"Network": ""}, "ConfigOnly": false, "Containers": {"1893dcb898d5299c5dd9cf5a2219f2e2f08956507afc56d86bfe64cb96e18837": {"EndpointID": "7b9ec7d78666c965795c34db03465562e4bb7f5bdfa21de71d5f69824c3b48a7", "IPv4Address": "172.20.0.2/24", "IPv6Address": "", "MacAddress": "02:42:ac:14:00:02", "Name": "mosquitto"}}, "Created": "2021-01-11T17:10:29.613448381Z", "Driver": "bridge", "EnableIPv6": false, "IPAM": {"Config": [{"Subnet": "172.20.0.0/24"}], "Driver": "default", "Options": null}, "Id": "9e6daec0c1bb385fc2d6459655602ab5ce127505e7e6eaea091c9e5af7b5a1f0", "Ingress": false, "Internal": false, "Labels": {}, "Name": "syntropynet", "Options": {}, "Scope": "local"}}, "changed": false, "network": {"Attachable": false, "ConfigFrom": {"Network": ""}, "ConfigOnly": false, "Containers": {"1893dcb898d5299c5dd9cf5a2219f2e2f08956507afc56d86bfe64cb96e18837": {"EndpointID": "7b9ec7d78666c965795c34db03465562e4bb7f5bdfa21de71d5f69824c3b48a7", "IPv4Address": "172.20.0.2/24", "IPv6Address": "", "MacAddress": "02:42:ac:14:00:02", "Name": "mosquitto"}}, "Created": "2021-01-11T17:10:29.613448381Z", "Driver": "bridge", "EnableIPv6": false, "IPAM": {"Config": [{"Subnet": "172.20.0.0/24"}], "Driver": "default", "Options": null}, "Id": "9e6daec0c1bb385fc2d6459655602ab5ce127505e7e6eaea091c9e5af7b5a1f0", "Ingress": false, "Internal": false, "Labels": {}, "Name": "syntropynet", "Options": {}, "Scope": "local"}}After adding your config, it’ll look like this:TASK [create_docker_network : Create Docker network] *****************************************************************ok: [broker] => changed=false ansible_facts: docker_network: Attachable: false ConfigFrom: Network: '' ConfigOnly: false Containers: 1893dcb898d5299c5dd9cf5a2219f2e2f08956507afc56d86bfe64cb96e18837: EndpointID: 7b9ec7d78666c965795c34db03465562e4bb7f5bdfa21de71d5f69824c3b48a7 IPv4Address: 172.20.0.2/24 IPv6Address: '' MacAddress: 02:42:ac:14:00:02 Name: mosquitto Created: '2021-01-11T17:10:29.613448381Z' Driver: bridge EnableIPv6: false IPAM: Config: - Subnet: 172.20.0.0/24 Driver: default Options: null Id: 9e6daec0c1bb385fc2d6459655602ab5ce127505e7e6eaea091c9e5af7b5a1f0 Ingress: false Internal: false Labels: {} Name: syntropynet Options: {} Scope: local network: Attachable: false ConfigFrom: Network: '' ConfigOnly: false Containers: 1893dcb898d5299c5dd9cf5a2219f2e2f08956507afc56d86bfe64cb96e18837: EndpointID: 7b9ec7d78666c965795c34db03465562e4bb7f5bdfa21de71d5f69824c3b48a7 IPv4Address: 172.20.0.2/24 IPv6Address: '' MacAddress: 02:42:ac:14:00:02 Name: mosquitto Created: '2021-01-11T17:10:29.613448381Z' Driver: bridge EnableIPv6: false IPAM: Config: - Subnet: 172.20.0.0/24 Driver: default Options: null Id: 9e6daec0c1bb385fc2d6459655602ab5ce127505e7e6eaea091c9e5af7b5a1f0 Ingress: false Internal: false Labels: {} Name: syntropynet Options: {} Scope: localThat induces much less anxiety! By placing the .ansible.cfg file in your home directory ( ~/ ), you’re making it global.

You can use any cloud provider currently supported by the Syntropy Stack. Check their documentation for a complete list. Using different providers isn’t an absolute requirement, but we do this to help illustrate the flexibility, interoperability, and ease of use when working with the Syntropy Stack across the expanse of the internet. The most important thing is that your VMs don’t share a public IP address. So, if you don’t want to use three separate cloud providers, try placing your VMs in different geographic regions. The most important thing is that they don’t share a public IP address. I have 3 basic VMs from Digital Ocean, GCP, and AWS. I used these providers as I already have accounts with them and am familiar with their services. that I chose to set up my VMs as follows:FluentD: Digital Ocean, Type: Basic, 1vCPU, 1GB memory, OS: Ubuntu 20.04Elasticsearch: Google Cloud Platform, Type: e2-micro, 2vCPU, 1GB memory, OS: Ubuntu 20.04Kibana: AWS, Type: t2-micro, 1vCPU, 1GB memory, OS: Ubuntu 18.04All three of these options are in the same price range (around $5–6/month) and are sufficient for the purposes of this example.Setting up each VM on a particular cloud provider is beyond the scope of this post, but I’ve included some links to guides below to help get you started if you’re not sure how to go about creating the VMs. You’ll want to add your SSH public key so you can access your VMs from the terminal using SSH. I’d recommend installing Ubuntu as your OS to ensure the commands I share translate directly. But of course, if you’re comfortable with other flavours of Linux, by all means, have at it. The fact that the Syntropy Stack leverages docker means that we’re distro agnostic!Creating an AWS EC2 instanceQuickstart using a Linux VM | Compute Engine DocumentationHow to Create a Droplet from the DigitalOcean Control Panel | DigitalOcean Product DocumentationQuickstart - Create a Linux VM in the Azure portal - Azure Virtual MachinesSSH KeysAs a personal preference, I prefer to create separate SSH key-pairs for different projects or tasks, depending on the scope. For example, I have a dedicated syntropy_rsa keypair that I use with all of my Syntropy VMs.If you want to create a new key-pair, you can use the following command. The -N flag just creates a key-pair without a passphrase, which is useful for certain automated tasks (like GitHub workflows, for example). The "user@host" is just a way of identifying the keypair. Feel free to use something like syntropy@local .$ ssh-keygen -t rsa -b 4096 -C "user@host" -q -N ""Enter file in which to save the key (/Users/craig/.ssh/id_rsa): /Users/<user>/.ssh/syntropy_rsaNext you’ll want to authorize your new key on your VMs. Add your new public key to each of your hosts authorized_keys file. You can do this from your local dev machine’s command line. The <host> will be your VM’s public IP and the <user> will be the Linux username for that VM. For example, on AWS the EC2’s default user is always ubuntu .Eg.ssh-copy-id -i ~/.ssh/syntropy_rsa.pub <user>@<host> -fYou can also do this manually if you don’t have ssh-copy-id available. Just SSH into your VM and add the public key to the ~/.ssh/authorized_keys file. You can copy your public key to the clipboard using:pbcopy < ~/.ssh/syntropy_rsaJust bear in mind that, depending on your cloud provider, you’ll probably have to add your SSH public key via their UI/console before you’ll have SSH access. For example, on Digital Ocean, you need to add your public key via Settings > Security.Adding an SSH public key to Digital OceanThe final thing you may need to check is that port 22 is open to inbound traffic.
