Feb 2020 Update

As a follow up to the Feb 2020 Monthly Update Video below are some additional details on our two priorities: year has been off to a tremendous start for The OAN. Over the past two months we’ve continued to progress quickly and we’ve achieved multiple milestones towards our two key focuses for 2020; launching a consumer application that solves a vital platform problem and increasing the global awareness of Aion.1) Building a Consumer-Facing AppAt the current state of maturity in the blockchain ecosystem, we need to directly own our relationship with end users in order to achieve product-market fit. If we rely solely on third parties, we cannot develop empathy for our audience and establish rich feedback loops. As such, we are scaling our product teams to develop a consumer-facing application, leveraging The OAN tech stack. This focus enables us to control our adoption strategy and showcase how The OAN can solve real problems within platform economies.After months of product discovery, we’ve identified significant gaps in the accessibility and affordability of basic products and services for gig-workers. In the U.S, over 35% of the workforce participated in the gig-economy in 2019. Despite the massive growth of gig-workers and the platforms they operate on, basic services such as insurance, pensions, and credit remain difficult to access, unaffordable or ineffective. If the pace of this growth continues by 2027, 50% of the U.S workforce will be participating in gig-work. We believe that new bottom-up solutions focused on the individual can increase the financial mobility, security and well-being of this rising workforce.You can read more about the gig-economy and our thoughts below:Fixing the Unintended Consequences of the Gig EconomyHistory Repeats Itself For Gig Economy Workers — And Not In A Good WayFreelancing in America: 2019 — by UpworkIn order to build this solution, we have established and grown our product development team to eleven people including a mix of technical development, research, design, and product management. The product development team has been focused on product design and validation as we approach our private alpha testing this spring.The marketing team has begun the new brand development for the app so we’re very excited to share initial branding elements with you soon!2) Building Aion Awareness & ValueIn order to scale the security of the network, Aion must continue on the path to establish itself as a leading digital asset. Supporting and growing the value of Aion is critical to the sustainability of network operations. We have established a Growth team exclusively focused on Aion marketing, ecosystem development (exchanges, custodians, validators) and relationship management (stakers, miners, investors). This team, in collaboration with external partners, will grow global awareness and access to Aion.A few recent milestones in the Aion ecosystem:New exchange listing with Bithumb KoreaOver 120 million Aion staked with 40+ validatorsAdditional Binance pairings of Aion-USDT & Aion-BUSDBlockchange Ventures doubled-down on its Aion investmentHired 3 new marketing team membersKorean Telegram community grew from 194 to 2724 in February (1404%)WeChat Official account following grew from 147 to 1009 in February (686%)Looking ahead, we’re very focused on our two key priorities that we can rally the team around and we’re excited to share more updates with the community throughout the year.Feb 2020 Update was originally published in Aion on Medium, where people are continuing the conversation by highlighting and responding to this story.

The Making of: The OAN & Aion

The Making of The OAN & AionThe launch of The Open Application Network and the updated Aion brand on November 4th was a significant milestone for both the project and our team. This launch included both a new POV and strategic direction as well as a major brand update. Although publicly the new brands appeared abruptly, their creation was months in the making so we wanted to share some insight with our community into the strategy and decisions we made to build these brands.Last week Matt Spoke wrote a blog post explaining our new strategic direction which will give you more context before we jump into the branding below.Branding The Open Application Network.The branding for The Open Application Network was inspired by the Swiss Style used by IBM during the late 60s and early 70s; the dawn of the personal computing age when the promise of what technology could bring felt equal parts exciting and science fiction.We didn’t want the brand to feel like yet another tech company with a two-syllable name set in a lowercase sans-serif typeface hell-bent on being the cool new thing. Instead, we embraced a simple, warm, utilitarian style with an aesthetic rooted in a deep sense of purpose before beauty.Even calling the brand “The Open Application Network” was a decision made to help reinforce the idea that The OAN isn’t just another tech start-up but a public utility. A longer, more official sounding name reminiscent of organizations like the Metropolitan Transit Authority or the Environmental Protection Agency helps reinforce how developers should think of this public infrastructure.The Open Application Network’s Primary Brand LogoPrimary OAN LogoThe Open Application Network’s primary logo is set in Aeonik. This typeface seemed almost kismet given the official digital asset of The OAN is Aion. How could we say no to that? The word-mark’s accompanying icon is comprised of an “O” an “A” and a stylized lower case “N” nested within one another. These three letter forms disassemble to work on their own as a secondary mark for The OAN. The idea of being able to work both separately and together is a core value of The OAN. The circle, triangle, and square work as simple shapes that represent the building blocks of the network infrastructure.The OAN Primary Logo and Seconday Mark in HarmonyAion’s New Brand Logo and Currency SymbolPrimary Aion LogoAion is the digital asset of The Open Application Network. The Aion brand has established equity, especially with the coin-holder community, so we kept the name and updated the visual identity to work seamlessly with The OAN master brand identity. Rather than complicating the system with a secondary mark that would double as a currency symbol we integrated the symbol into the main word-mark for better comprehension and brand recall.The capital “A” in the new logo is made up of the peaked frame of the uppercase “A” which doubles as a chevron pointing upwards to symbolize prosperity. The cross bar was replaced by a circle the same size as the dot over the lowercase “i” to symbolize a coin. Like traditional currency symbols, the Aion symbol was designed to be simple enough to write with a pen using only strokes and dots. The result is a currency symbol that is incredibly easy to write or type in a variety of weights, and a simple word-mark that feels perfectly at home in the parent brand’s overall look and feel.Aion Currency SymbolConclusionNone of this would be possible (including this blog post) without the help of our branding and design agency Conflict. Conflict was instrumental in the strategy, design, and execution of these brands and will remain a trusted partner of ours moving forward. They led the creation of our assets from the New York Times full-page open letter to the animations on our Twitter, including a comprehensive brand guideline document. The brand guidelines and logo assets are publicly available to guide our community and partners to make images, videos, and memes on-brand (we love when you do!).We hope this gives some insight into why these brands look and feel the way they do. We love how creative and engaged our community is, so please send pics of any branded SWAG you make and remember to follow the guidelines as best you can.The Making of: The OAN & Aion was originally published in Aion on Medium, where people are continuing the conversation by highlighting and responding to this story.

Unity Staking Interface Live

We’re very excited to announce that the Aion Staking Interface is now live and ready for delegation! As of today, Aion holders can select and stake their Aion with the available Staking Pools on the interface. Over the coming week, Staking Pools will be continuously onboarding onto the interface leading up to the Unity upgrade on November 19th-20th (block time dependent). Once the Unity upgrade has taken place, the production of PoS blocks will begin. This new Aion Staking Interface is your one-stop-shop for all staking services for The OAN.Please note that until the Unity upgrade has taken place, no PoS blocks are produced and therefore no rewards are distributed to pools or delegators.The Aion Staking Interface features the ability to access your account through Ledger, key-store, private key, and mnemonic phrase. The desktop application is available on Windows, Mac, and Linux for key-store, private key, and mnemonic phrase.Key Features:Delegation A coin holder can delegate Aion to a staking pool that runs node infrastructure on the network. When the staking pool that you have delegated to produces a block on the network, you earn a share of the rewards.Un-Delegation A coin holder can un-delegate their stake at any point in time. There is a lock-up period of approximately 24 hours (based on block times) after which the stake is transferred to the staking account.Withdrawal Rewards are distributed for successful block production among delegators of a stake. A coin-holder can withdraw these rewards anytime instantly to their account.Last week we announced our initial list of staking pool partners, you can see the full list on the Aion Staking Interface as they register, and you may choose to delegate to one, or multiple pools. If you have any questions, please visit our community social channels or submit a ticket on our official support otherwise start delegating today!Important LinksStaking InterfaceSupporting DocsCommunity SupportAion Support (2–3 days)Unity Staking Interface Live was originally published in Aion on Medium, where people are continuing the conversation by highlighting and responding to this story.

Unity is coming

It’s coming. Miners and Stakers working together. Unity is a major milestone in both hardware and economic security models for blockchain network consensus. It brings together the unique characteristics of each of these models to provide a security design that doesn’t sacrifice availability, unpredictability or decentralization.Leading up to the hard fork on November 19th-20th, 2019 the Unity — Aion Kernel will be upgraded by node operators. As soon as the upgrade is complete, Unity will be live and a new stake-based type of block production will be introduced into Aion. This marks another major milestone, Aion will be one of the first major networks to migrate from PoW and introduce a new consensus design on a live network. Coordinating this type of upgrade is only possible due to the amazing community of node operators around the world that run Aion’s infrastructure. Once the network is upgraded, Aion holders all over the world will be able to participate in the security of the network and be rewarded for their efforts. Holders can stake privately or through an ecosystem of world-class validators (to be announced shortly) that have come together to support the Aion community.In advance of the upgrade, documentation will be released to guide holders through the delegation experience and using the amazing staking interface which will be your home-base for all staking related functions. In addition, we will be releasing the Unity Economic Overview which outlines changes to the block rewards and Aion issuance.For more information on Unity see the links below:Unity White Paper PDFUnity Non-Technical OverviewUnity Consensus Proof of ConceptUnity Staking Contract OverviewUnity is coming 🎉 was originally published in Aion on Medium, where people are continuing the conversation by highlighting and responding to this story.

Unity Staking Contracts Ove...

At the heart of the Unity Consensus are the staking and stake delegation mechanisms, which are responsible for managing staker registrations and stake updates. In this article, I will walk you through the design considerations we’ve made and the implementation details. The source code is available at This article is an overview of the current state of the Unity Protocol Contracts, which are still in their infancy stage and are constantly evolving.Design ConsiderationsAny Proof-of-Stake(PoS) based system needs a way of managing the stake state, i.e. the registered staker list and the amount of stake of each staker at any time. This piece of information decides the eligibility of a staker to produce a PoS block, and has to be agreed on by the whole network.The stake management is traditionally implemented within the client (software that a node uses to connect to the network), using purpose-specific transaction types, with the utilization of databases or data storages. This is mainly due to the lack of programming capability above the protocol. The consequence of such a design is to make the protocol itself heavy and fat. As a result, it’s very difficult to implement such a system, given that there might be multiple clients in different programming languages.In the Unity Consensus, we implement the staking and stake delegation mechanisms in AVM smart contracts. Such a design choice gives us two advantages:The execution and storage model of a smart contract is well defined, so it will be cost-free to ensure consensus on the stake state;The user interaction will be simple, as a user can interact with a smart contract using existing transaction infrastructure (no extra tool is required).Staker Registry ContractFirst, let’s take a look at the staker registry contract, which is the endpoint to all users for participating in staking. A staker needs to be registered in this contract before it can produce a valid PoS block. A coin-holder can vote/unvote for a registered staker and even transfer stake between two stakers.The internal structure of the staker registry is shown in the picture below. One staker registry is associated with a collection of registered stakers, pending unvotes and pending transfers. To understand the state/lifecycle of coins, I refer readers to the Section 2.4 of the Unity Engineering Specs. A copy of the coin state transition diagram is also attached below.Structure of the staker registry contractCoin states and state transitions from the perspective of the staker registryThe staker registry contract is privileged, in a sense that the kernel depends on it for deciding the validity of a PoS block. Despite being privileged, this contract is designed to be simple and the kernel-contract interaction is limited to just one stateless method call (a stateless method call doesn’t change the state of a smart contract during execution). This method is getEffectiveStake(signingAddress, coinbaseAddress), which returns the effective stake of a block producer.Register A StakerAnyone can register a staker by calling the registerStaker method of the staker registry, which has the following parameters.identityAddress — (unique) An address used to identify a staker;managementAddress — The address of the management key used when updating the staker, e.g. updating signing address;signingAddress — (unique) The address of the key used for signing a PoS block;coinbaseAddress — The address used for receiving block rewards;selfBondAddress — The address used for calculating the self-bond stake of a staker (self-bond stake of a staker is the stake from its owner).Separating the stake of staker owner from the stake of other voters gives us additional benefits and flexibility. For example, we can then apply self-bond percentage requirement and min self-bond requirement.VoteVoting is the process of converting liquid coins into stake. To vote for a staker, a coin-holder needs to call the vote(staker) method, with a specific amount of coins being passed along. The coins will be in the custody of the staker registry contract after voting.UnvoteTo revoke a stake and retrieve the coins, one needs to call the unvote(staker, amount) method, which will cancel the stake, lock it for a pre-defined period of time, i.e.UNVOTE_LOCK_UP_PERIOD, and return a unique PendingUnvote ID, if the request is valid. It’s only after the lock-up period that the user can really get its coins back, by calling the finalizeUnvote(id)method.Transfer StakeThe staker registry also allows a voter to transfer stake from one staker to another. This allows voters to swap stake between block producers without going through an unvote-and-vote process, which would involve the unvote lockup period.To transfer stake, one needs to call the transferStake(from, to, amount)method, which returns a PendingTransfer ID upon valid request. The user needs to call the finalizeTransfer(id) method to complete the stake transfer, after another lock-up period, i.e. TRANSFER_LOCK_UP_PERIOD.Pool Registry ContractWhile the staker registry is easy to interact with, many coin-holders would prefer to delegate their stake to a pool rather than to maintain a node and stake on their own. We call this group of people delegators. A pool receives stake from and re-distribute the block rewards to its delegators.In the Unity Consensus, a decentralized stake delegation system, as in PoolRegistry smart contract, is designed and implemented. This is made possible by the following conditions:The staker registry is a smart contract which allows the pool registry to interact with via the inter-contract CALL;An efficient reward distribution algorithm (F1 fee distribution) is proposed by Dev Ojha.Unlike staker registry, the pool registry is un-privileged and implemented purely based on the existing framework provided by AVM. An architectural view of the design is shown below.Pool Registry ArchitectureAt the very front is the PoolRegistry, which is the endpoint for all pool owners and delegators. For each registered pool, the registry maintains a PoolState , which is associated with one PoolCoinbase, one PoolCustodianand one PoolRewardsManager.The PoolCoinbase is smart contract instance, in the control of the pool registry, whose only purpose is to receive block rewards;The PoolCustodian is another smart contract instance, in the control of the pool registry, which is the custodian of the pool owner’s stake;The PoolRewardsManager is an internal object, which calculates the share of rewards of each delegator to a pool.Register A PoolTo register a pool, the owner needs to go through the following steps:Publish the meta data, e.g. name and description, in a JSON file at a publicly accessible URL (the scheme of the JSON file is being actively defined).Call the registerPool(signingAddress, commissionRate, metaDataUrl, metaDataContentHash) method of the pool registry, where signingAddressis the address of the signing key to be used for block production, comissionRate is the service charge in percentage that the pool owner wants to take, and metaDataUrl and metaDataContentHash are the URL and hash of the meta data respectively.After these two steps, the pool can start accepting stakes from delegators, including the pool owner itself. As long as the min self-bond stake requirement is satisfied, the pool owner can use the signing key to produce blocks and earn block rewards.An interesting implementation detail is that the registerPool method is convoluted. It creates a staker in the staker registry, instantiates a PoolCoinbase and aPoolCustodian, and configures the staker properly. This will ensure that all block rewards of the pool go to the pool registry.DelegateTo delegate stake to a pool, one just needs to call the delegate(pool)method along with some amount of AION coins to stake. The pool registry uses the received coin to stake in the staker registry.UndelegateTwo steps are required to cancel a delegation. First, the delegator needs to call the undelegate(pool, amount) method of the pool registry, which will initiate an unvote operation and return a PendingUnvote ID. Second, it has to call the finalizeUnvote(id) method to finalize it after the unvote lock-up period.WithdrawWithdrawal is the process of claiming back the block rewards one delegator has earned so far. This is being done by calling the withdraw(pool) method, which will transfer the rewards to the delegator upon a valid request. For how the contract decides the block rewards, check the F1 fee distribution scheme.Redelegation and Auto-redelegationRedelegation is the process of delegating to a pool using the earned block rewards from that pool. This is essentially a combination of withdraw and delegate.Auto-redelegation enables one delegator to allow others to redelegate its block rewards. This is implemented by introducing an auto-redelegation market. If a delegator sets an auto-redelegation rate, then anyone can call the pool registry to auto-redelegate the delegator’s rewards on its behalf. The caller will get a portion of the rewards as incentives based on the auto-redelegation rate.How Do Coins Flow?In case someone is interested in how the coins flow in the delegation system, an overview is provided below (boxes with shadow background are smart contract instances). Intuitively, all delegator’s stake and PoS block rewards are in the custody of the Pool Registry contract; all pool owner’s stake is in the custody of the Pool Custodian contract. If the coins are for delegation, then they flow to the Staker Registry.Flows of coins in the delegation systemThat’s It!Now, you’ve gone through an overview of the Unity staking and stake delegation contracts.

Unity Consensus — Proof-of-...

Unity Consensus — Proof-of-ConceptIntroductionIn this article, I’m going to walk you through the Aion Unity Proof-of-Concept (PoC) implementation. If you haven’t heard about Aion Unity, read this “zero-to-hero” blog post.The PoC comprises of four components:A stake registry contract which manages the staker registration and handles stake/unstake requests,A new block structure, along with a set of validation rules, to account for two block types — PoW blocks and PoS blocks,A staking client, analogous to mining software, that eagerly generates PoS blocks when it is eligible to do so,An implementation of the difficulty adjustment algorithm and fork choice rule.The objective of the PoC is to validate the key metrics presented in the Aion Unity paper and to simulate different attack scenarios. The metrics studied include block time, block reward distribution, and orphaned block rate.The PoC ImplementationStake Registry ContractThe Stake Registry Contract is the smart contract that manages the staker registration and processes vote/unvote requests (a.k.a. stake/unstake respectively). Any coin-holder with a minimum balance is allowed to register as a staker to participate in Unity consensus. Others can vote or unvote for a registered staker. Liquid coins become locked stake after a vote operation, and return to being liquid after an unvote operation, subject a to lock-up period.The source code of the stake registry contract is available here. Although the smart contract is written in Solidity, it will later be rewritten in Java, to run on the AVM. Also, the enforcement of minimum registration stake and the unvote lock-up period are not implemented in the PoC.Extended Block StructureIn Aion Unity, the blockchain structure is a singly linked list of PoW blocks and PoS blocks, with no intervening requirement. To distinguish a PoS block from a PoW block, we extended the original Aion block structure with additional fields. Specifically,A sealType field is added to identify the block type;For a PoW block, the seal field consists of a nonce and an EquiHash solution;For a PoS block, the seal field consists of a seed and a signature of the block header from the staker.We have a new set of validation rules for PoS blocks, as follows:Validate the block header using the existing PoW validators, but skip the seal field validation.Validate that the seed is a valid ED25519 signature of the seed of the previous PoS block, and recover the signer’s address (let’s call it signer1).Validate that the signature is a valid ED25519 signature of the block header, and recover the signer’s address (let call it signer2).Validate that signer1 and signer2 are equal.Look up the signer’s stake from the state database and compute the PoS block generation delay.Validate that the delay is lesser than or equal to the duration between this PoS block and the previous PoS block.Staking ClientTo generate a PoS block, a staker needs to actively look up its stake and compute the block generation delay. When it’s eligible to generate a block, it creates a block template and signs it.We call the software that performs this lookup, waiting, and block production a staking client. It needs to be able to:Manage the staker’s private key,Check the PoS block generation delay by communicating with a full synced node,Sign block templates created by the node.The full PoC implementation of a staking client is available here.Fork Choice RuleAion Unity uses a different choice rule to deal with forks on the network. It always selects the chain with the highest product of total mining difficulty and total staking difficulty. The total mining difficulty is simply the sum of the difficulties of all the PoW blocks on the chain; the total staking difficulty is that of the PoS blocks.The way the fork choice rule is implemented in the PoC is to keep track of the total mining and staking difficulties of each block. When a new block is imported, either the total mining difficulty or staking difficulty is updated, as appropriate.Difficulty Adjustment AlgorithmTo maintain a targeted block time, the difficulty should be adjusted dynamically as miners and stakers join and leave. The mining/staking difficulty increases if the block time is too small, and decreases if the the block time is too large. Check here for the PoC implementation.The PoC ResultsKey MetricsTo test how the PoC implementation works, we set up the following cluster:8 nodes connected via an intranet;4 of them are mining (1 Nvidia GPU each);The other 4 nodes are staking (1000, 2000, 3000, 4000 nAmp respectively).We let the network run for 2500 blocks, and then calculated the following statistics:Block time statistics between block #500 and block #2500Orphaned blocks between block #500 and block #2500The mining difficulty over timeThe staking difficulty over timeBlock reward distributionBy analyzing the collected data, we found that the key metrics for the PoC implementation match what has been presented in the Unity paper:The average block time is very close to the targeted 10 seconds;The difficulty adjusts from 1 to the right level within 200 blocks, with the given network configuration;The number of PoS blocks and PoW blocks are roughly the same;The block rewards of a miner are proportional to the mining hashrate, while the block rewards of a staker are proportional to the amount of stake.Network Partition AttackIn this experiment, we assessed the ability of the network to recover from a period of broken connectivity. To test it, we partitioned a cluster into two groups for a period of time, and then rejoined them.By observing the weight growths of the chains of the two partitions, we found that both partitions could progress independently (liveness is maintained). When the connectivity issue was resolved, the network chose the chain with a higher weight. The experiment helped us identify some syncing issues in the kernel implementation, which were fixed.What’s Next?So, what’ next after the Aion Unity PoC implementation?The Aion Unity economics design will be published soon. The Engineering team is busy productionizing Aion Unity.

Dashboard Updates

The Aion Dashboard UI and API are key pieces to providing visibility into the Aion blockchain. The Dashboard UI allows users to view transactions, token transfers, analytics and other activity on the Aion Smart Contract Platform. The Dashboard API allows developers to access data for accounts, blocks, and transactions from within their apps.Motivation for the updateThe motivation for this update was to achieve feature parity between Java and Solidity on the Dashboard. A new controller versioning convention was implemented on the API to eliminate breaking changes on the Dashboard. This allows developers going forward to be certain that new dashboard releases will not contain any breaking changes.New FeaturesBlock rewards are now supplied by the Aion Kernel rather than being calculated by the API.ATS tokens written in the AVM Scripting Language can now be read by the Dashboard.ATS token transfers and balances can now be read by the Dashboard.A new controller with the new endpoints /v2/dashboard/block and /v2/dashboard/transaction was added.Bug FixesThere was an issue which caused transactions that contained token transfers to return an incorrect value. This has been fixed.Breaking changesUsers of the Aion Dashboard ETL will need to perform a full network sync in order to update to the new version of the ETL.Users of the Aion Dashboard API will now need to parse the tokenTransfers field in the transaction to view the token transfer value.You can now view the updated Mainnet Dashboard and Mastery Testnet Dashboard.You can also view the Dashboard API docs.Dashboard Updates was originally published in Aion on Medium, where people are continuing the conversation by highlighting and responding to this story.

Aion Community Commitment

One of the best parts of the Aion Network is the strength, passion, and engagement of its community. From around the world this eclectic group comes together every day to explore, build, debate, and learn more about the future of the internet. The foundation has a great appreciation for the community and often leans on its members to echo our announcements, test our network, knock down doors for us, and hold us accountable to our promises.As we grow, so does our community. This growth requires an increasing amount of attention and resources for us to properly foster and engage the community. Part of that time and attention is to keep things friendly, respectful, and non-judgmental. We believe that these qualities will in the long term foster the kind of atmosphere required for innovation.To dateFor those that haven’t always been with us, we’ve gone through a few variations of community management that have involved full time resources in Telegram, to other formats with moderator proxy groups. We’ve learned a few things as we’ve grown and we want to renew our commitment by doubling down on what’s working and proposing some new initiatives that we think will benefit the project.Going ForwardWe want to commit to a few initiatives that will involve participation from everyone and enable two-way communication.Weekly Community Reddit AMA 👇r/AionNetworkThe Weekly AMA is a reoccurring opportunity for the community to engage with the Aion Foundation team in a Q&A format. This is the most frequent and easiest way for your questions to be answered that aren’t addressed in blog posts or other Foundation communications. We aim to rotate in members from different pods to provide varying perspectives from the Foundation.We’ve been doing this for five months now and will continue to support it and let it evolve. We don’t expect employees to be in Telegram everyday so this is an ideal format for them to engage directly. The more questions you ask, the more we can share!Monthly Video Update from Matt Spoke Monthly Video Update is a summary of the main project updates from the month, including some additional commentary from Matt Spoke and other Foundation members. The Monthly Update Videos are posted to the Aion YouTube.We all appreciate these videos. Since the inception of the project they’ve kept us in the loop with what is going on at a high level and offer a unique perspective most projects are not providing the public.Quarterly Financial DisclosureHow We OperateThe Aion Foundation believes in holding itself to the highest standards in governance and accountability. Releasing quarterly financial reports is a major part of our commitment to transparency. All reports can be found here.This is a cryptocurrency leading initiative that sets precedent. We will continue to put these reports out, and expect more from our peers when it comes to financial transparency. Create the world you want to see!Quarterly Video AMA from teamThe Quarterly Video AMA is designed to be a more personalized and engaging format for the AMA. The Video AMA follows the same Q&A format as the standard weekly AMA.This is new, and will aim to be a larger, more inclusive live AMA to field questions, share asks, and get aligned across multiple areas including network security, integrations, development, accessibility and more.Quarterly Community SurveyAlthough we currently gather suggestions from community discussions, the quarterly survey will provide a quantitative and fair approach to hear from each member of the community on a regular basis. Following results analysis the survey results will be published along with our resulting action items.This is also new. We field a lot of suggestions, concerns and feedback from many sources. It’s not always easy to sort signal from noise and we’re looking to focus on high leverage, big impact items. If and when you have specific asks that we implement, we have a process in place to track those asks to outcomes and report back to you on the end result.Community Rules of EngagementIn addition to the structured communication plan above, we’ll also continue to provide public updates through social media. Please do not expect foundation employees to respond to you 1:1 via Telegram— and if they don’t, please don’t take it personally. We need to both streamline our communication and avoid inconsistent information.Please also note that we’re often limited in our ability to share information due to many factors (Legal, NDAs, Regulatory, etc.) and as such we cannot comment or answer questions which would introduce risk to the project.Finally, we have worked with community moderators to draft a “Rules of Engagement” list that includes how to interact with the Foundation and it’s employees, community moderators and other members in Aion community channels. This list is simple, straight forward and is guided by a simple ethos: be a good person to others and have respect for the work we’re all doing together.⛔️Aion Official Channel Rules⛔️1️⃣ Be Respectful. Treat others as you would want to be treated. Personal attacks, harassment, trolling, and foul language are prohibited.2️⃣ Be Truthful. Cite to sources of information whenever possible. FUD, hype, fake news, and misinformation are prohibited.3️⃣ Keep it High-Quality. Add value to the conversation. Referral links, trading groups, phishing websites, advertisements, shilling, and duplicate content will be removed.4️⃣ Keep it Aion-Related. This is a channel to discuss Aion Network news, announcements, technology, and ecosystem partners. Promoting projects unrelated to Aion is prohibited.5️⃣ No Price Talk. Discussion about trading, market, and price discussion is welcome only on Aion_Trader Telegram or Aion Trader Reddit.6️⃣ Do Your Own Research. Answers to many frequently asked questions can be found using AionTGbot and AionNewfeed in the Aion Telegram channel or on the Aion Reddit Wiki.7️⃣ If You See Something, Say Something. Speak up if someone is violating the rules and notify admins for enforcement (reply to the offending message with “@admin”).Channel LinksTwitterRedditYouTubeTelegram, Telegram Info Bot, Telegram NewsfeedFacebookLinkedInDiscordGitterWish ListThere are a number of ways the community helps drive the Aion project forward. One way is to help get Aion on the radar of relevant publications (blogs, podcasts, etc.) who haven’t covered the project yet such as:The BlockEric from Proof of WorkLaura from Unchained PodcastEpicenter PodcastZero Knowledge PodcastArthur Falls from The 3rd WebOn May 4th we launched the public draft of the Unity Whitepaper outlining our proposed hybrid PoW/PoS consensus algorithm. We’ve created a simple form for your Unity specific feedback here.Lastly, our Ecosystem Pod has been hard at work creating new documentation that we welcome feedback on via GitHub:End to End IntelliJ TutorialA fully updated tutorial on how to write, compile, deploy, and call a Java contract using IntelliJ.Ethers.js ExamplesA bunch of example functions you can do with Ethers.js. Includes a sample contract.Web3.js ExamplesA bunch of example functions you can do with Web3.js.Node OverviewA quick overview of what nodes are and what they’re used for.Digital Assets OverviewWhat digital assets are, and how they can be designed.Thank You.We genuinely want to thank you for your on-going support. We know it isn’t easy to be so dedicated and passionate about a project without full visibility into the decisions and actions being taken around it but we’re doing our best to be transparent. We’re working hard to rebuild the internet and are very grateful that you’re pushing along with us.Lastly, a big shout out to the community moderators! Although the community moderators are not Aion Foundation employees, without them, none of this would be possible.

Ethers.js selects Aion as i...

The most popular wallet implementation and Javascript Framework (and Typescript) API for Blockchain development is now available for Aion developers with support for Java smart contracts on the new Aion Virtual Machine (AVM).Ethers.js makes it easy for Blockchain developers to interact with the Aion Blockchain through a lightweight, well-maintained, well-documented, and robust typescript library that is tailored for front-end use.Apart from being significantly smaller than other Blockchain frameworks at only 88kb compressed, Ethers.js is focused on developer-friendliness. The main features include:Keep your private keys safeCreate JavaScript objects from any contract ABI, including ABIv2 and Human-Readable ABI for FVM Contracts and AVM ContractsAutomatically connect to a NodeSmith endpointFully TypeScript ready, with definition files and full TypeScript sourceCreated under an MIT License including ALL dependencies; completely open source for you to use as you pleaseWith a variety of smart contract platforms emerging, why choose Aion? The author of Ethers.js Richard Moore, stated:“With the Aion Network adding a Java-based smart contract Blockchain, it enables a whole industry (especially enterprise) of developers along with their tool-chains to get involved. The Java ecosystem has been around for quite some time, and has fostered a well-established collection of talent, debuggers, libraries, build-systems and knowledge-base of practices and security which will benefit the Blockchain space quite nicely.”Ethers.js initially launched on the Ethereum network in 2017 as a much-needed alternative to the Web3.js library for Blockchain developers. The Ethereum community seems to be split on Web3.js vs Ethers.js; however, Ether.js was released to the community almost two years after the release of Web3.js and it has quite notably generated much more interest and usage in a shorter time span.“I am still quite focused on Ethereum as a whole, but there is huge value in having a larger and more diverse community of blockchain developers.” — said Richard Moore.A grant was issued by the Aion Foundation to Richard Moore to support this integration to continue to improve the developer experience on the Aion Network.If you are interested in learning more:Check out the Aion Network Ethers.js tutorials and documentationSee the official Ethers.js documentationView the Ethers.JS x Aion GitHubRead Richard Moore’s blog post on the Ethers.js integration with Aion NetworkFollow Richard Moore on TwitterEthers.js selects Aion as it’s next platform was originally published in Aion on Medium, where people are continuing the conversation by highlighting and responding to this story.

Aion Virtual Machine (AVM) ...

The AVM hard fork has officially happened!What an incredible journey it has been to building the world’s first JVM-compliant Blockchain virtual machine. We set out on the mission to build the AVM over a year ago and it has truly been a team effort. Part of that team includes our passionate community who have been supporting and cheering for the project through the crypto winter and into the spring — Thank you!We made the strategic decision to leave the JVM intact so we could fully leverage the mature eco-system around it. Leaning on a hardened language like Java was crucial since a major obstacle for a business interested in Blockchain is the cost and time needed to train their teams on unfamiliar frameworks, languages, and tools. The AVM removes those obstacles and provides developers with a familiar and reliable development experience. We’re very excited about the projects already building on the AVM and can’t wait to see them go live. Aion strives to bring Blockchain to the mainstream and the AVM is the first big step towards that vision.See below for Matt’s monthly update video including the AVM launch with Jeff Disher and also Unity with Yao Sun: you’re interested in the Aion Research & Roadmap Team (ARRT) and/or the Unity project check out Yao’s AMA this Friday.If you, or someone you know is interested in building a dApp on the AVM, check out our Aion Docs for free comprehensive tutorials and tools to get started.Lastly, we’ve written a few AVM-related articles over the last year you might have missed so if you want a deeper dive, check out:Why Java and the JVMDebugging Java Smart ContractsAVM Hybrid StorageAion Virtual Machine (AVM) Live! was originally published in Aion on Medium, where people are continuing the conversation by highlighting and responding to this story.

BloxBean launches two new t...

BloxBean & Aion4jThe BloxBean project is directly aimed at providing Aion Virtual Machine (AVM) support for existing development tools and frameworks to achieve the following goals:Help on-board non-blockchain developers to the smart contract world via straightforward development toolsIncrease the productivity and confidence of smart contract developersLeverage and integrate with existing and familiar development processes instead of introducing drastically different flows i.e. you can use established Java processes such as unit and integration testing, CI, CD, etc.By supporting Java, AVM has already opened the possibilities of using established development tools in the Java ecosystem instead of re-inventing the wheel. In the first release, BloxBean consists of the Aion4j suite of tools:Aion4j Maven PluginAion4j Idea Plugin (IntelliJ IDE Plugin)While Aion4j Maven Plugin provides the command line development tools for AVM, Aion4j Idea Plugin makes those commands easy to use by integrating them directly inside of the development IDE.Suppport for MavenMaven is a popular build automation tool used primarily for Java projects.Maven’s primary goal is to allow a developer to comprehend the complete state of a development effort in the shortest period of time. Most of the modern Java IDEs have in-built support for Maven. So a developer can use any Java IDE to work with a Maven-based project.Aion4j Maven Plugin is a plugin which aims to provide end-to-end tooling support for smart contract development in Java. These smart contracts are executed on AVM via both an embedded AVM and an AVM running in a remote Aion kernel.Some of the key features supported by this plugin are :> Maven based AVM project creation using maven archetype.> Compile & Package> Unit Test> Deployment, test and debug on an embedded AVM during development> Deployment and test on remote Aion Kernel or hosted service like Nodesmith> Interact with Aion blockchain through maven commands(deploy, get balance, get receipt, call, contract transaction, transfer, get logs …)> Client side transaction signing> many more …AVM Archetype The AVM archetype is a template project that developers can build on top of when creating their own project. It comes with a contract and test. The goal is to provide a standard project structure which serves as a starting point for the new smart contract developer. The Aion4j Maven Plugin generates projects based on this template.IDEA Plugin (IntelliJ Plugin)Developers spend the majority of their development time within the IDE, making this tool a core piece of the end-to-end development lifecycle. Aion4j provides smart contract development support for JetBrain’s IntelliJ IDE, which is one of the most popular in the Java community.To make a developer’s life simple, it provides an Embedded AVM execution environment inside the IDE, which allows the developer to deploy and test smart contracts throughout development. Apart from simply installing the plugin on from the IntelliJ IDEA marketplace, developers do not need to install/download any other software to write and test smart contract on an Embedded AVM.Additionally, this plugin supports interacting with a remote Aion kernel straight from the IDE, so developers can deploy, test, and interact with their smart contracts without ever leaving their IDE during the entire smart contract development process. It also provides few editor level features such as “JCL whitelist check” where the editor warns the developer when trying to use restricted or non-allowed Java APIs in the smart contract code. Similarly, the “ABI type check” feature warns developers if any non-allowed data type is used as a parameter or return type in a callable method.The Aion4j Maven Plugin does most of the heavy lifting of interactions with the blockchain and the Aion4j Idea Plugin makes those functionalities easily accessible from IDE. So try out these tools and we would love to hear your feedback and suggestions.Also if you like building developer tools, you may want to contribute to these open-source projects and help in the adoption process.This is just the beginning of the tooling story for AVM …Helpful Resources:Aion Virtual Machine ( Docs: Website ( Maven Plugin ( Idea Plugin ( Archetype ( launches two new tools for Java developers building dApps was originally published in Aion on Medium, where people are continuing the conversation by highlighting and responding to this story.

A Methodology for Roadmappi...

Roadmap format includedThis methodology is a collaboration between Mike Mason and Yao Sun.The blockchain industry is still in its discovery phase, progress and innovation often come in bursts. As with all research driven fields, the environment is often highly entropic and incongruent to expectations of steady progression.The truth: it’s a paradox for us to message the entropy of the environment, then present a concrete and opaque timeline that gives the impression of concrete, steady progression. This practice, followed by many in the industry promote unrealistic expectations about how a research and discovery-oriented industry works and signals more to ambitions than realism.So, how can we promote the truth, keep the community (you) informed, and keep our mindsets clear for the next year?Some context before an answerWe’ve taken inspiration from mainstream and mature open source projects. They’ve got it figured out as their developer teams demand and rely on this being true.Time spent in this field acclimates you to the rate at which technologies that blockchains are dependant on oscillate in progression. To observe this effect we first need to split the scope of projects within the blockchain space between:Tinkerers: Those that innovate use-cases on top of a blockchain platform, using existing tools that are available.Tool Builders: Those that seek to expand the toolbox.For Tinkerers, timelines are often dictated by the time it takes the iron out the use-case, assemble the required components (Smart Contracts, off-chain storage & computation source, user frontend) in various configurations to match the user requirements. In projects like these timelines are often feature based, predictable and based on the scope and feature set of the use case. This is in contrast to timelines of tool builders, which seeks to expand the toolbox, to enable use-cases that would not exist without the expanded toolbox.We believe this is the true nature of progression in the blockchain industry; discoveries that suddenly and fundamentally change the ideas and assumptions of what is possible. A good example of this is the tried and true use-case that Ethereum enables, leading to wide adoption of blockchains for a variety of use-cases. Another upcoming example is that of Algorand, with the introduction of VRFs that is quickly being adopted into other projects and impacts the way on-chain randomization is viewed.In fact, a lot of the most important discoveries are being made by various teams around the world within the last year. The right people, right place, right time make the biggest changes to the industry.If you believe this, then the idea of roadmaps as a list of bullet point and timestamps is jarring and incongruent. In truth, diving into a research field and signalling as such while also providing a concrete roadmap is paradoxical but common within the industry. Too often, the hardest parts of a project get hidden under a relatively mundane grouping. The consequence: the reader is often misled about the complexity of a project and then confused when items don’t come to fruition.The best roadmaps are ones from projects that have a statistically viable sample to draw requirements from, ones that must be diligent and organized about roadmaps for their impact to downstream dependencies. We found similarities within roadmaps for these projects that convinced us of their effectiveness:Thematic ConsistencyRoadmaps should convey clearly an overall theme that guides the overall motivation behind each item within the roadmap. It should be very clear to the reader how each item feeds into this overall theme. This conveys a sense of priority for the audience and encourages a healthy convergence of expectations throughout the year.A Logical BreakdownFollowing on from the theme is a logical breakdown of items within the roadmap as they concern different elements of the system and different parties. This grouping naturally creates a more detailed context about the tasks themselves, who would be performing them and how their scope (from our perspective) relative to the global.Clarity of contentIt should never be difficult for a reader to understand what is being worked on. While predicting the future can often be an impossibility, what is being worked on now and our predictions for future targets should always be conveyed in an easily digestible manner. In fact, the system that worked best for our teams internally is one that conveyed a good sense of progression through the breakdown of items into logical tasks and checkpoints and assigning them priority and perceived difficulty/risk of these items.Secondly, descriptions should account for an increasing level of emergence, depending on the depth the reader is willing to go. This amounts to providing simplified “here’s the gist” descriptions to all users, and providing more in-depth details, examples, and reference content to those interested. Where applicable, readers should be notified how this change impacts them. This is critical to downstream dependencies that may be dependant on changes to the network.Beyond the principles mentioned above, here is a structural format we believe is a good representation of what should be included in a roadmap.The Roadmap FormatFeel free to use it for your project!ConclusionIn the coming weeks we will be releasing our roadmap to the public with this format as our guide. The roadmap takes into account work being undertaken across the Foundation from research, to production development, to ecosystem funding, documentation and more. From all the things we looked at, arguably the most important was “Recommendations”, a roadmap feature we only saw from the React project. This roadmap feature is philosophically in line with how we think about this document in that it is “real talk” aimed at letting you know what this milestone means for you, given you’re developing on the platform. Stay tuned for updates on this in the coming weeks!A Methodology for Roadmapping Public Blockchain Networks was originally published in Aion on Medium, where people are continuing the conversation by highlighting and responding to this story.

Like building developer tools?

We need your help.Apply to build these tools → hereIn 2019, we will shift main support of our Virtual Machine to the Aion Virtual Machine (AVM). A Java VM that will unlock a new development environment and programming workflow for developers building on blockchain protocols. This shift requires a set of self-sustained tools and add-ons to popular Java development tools. If you like building developer tools and would like to get paid for your efforts, we’d like to bridge those two desires. 🙏First off…If you haven’t already, read the following posts about the Aion Virtual Machine (AVM). In them, we walk through why we see promise in the Java ecosystem for our Virtual Machine as well as what a smart contract in Java looks like.Aion Virtual Machine (AVM): Why Java and the JVM?Hello World … from the Aion Virtual Machine!The Java Development WorkflowEarly on in this project, we found it was going to be important to understand how Java developers currently work. We didn’t want to force developers into adopting new workflows or do things that they’re not used to already doing. So we decided to focus on integrating blockchain development into existing Java workflows.From this, we found that there were four logical groupings for development tasks:From here, we isolated areas in the workflow (specifically development, testing, and deployment) that have blockchain tooling requirements where the developer is blocked as well as quality of life experiences that will make development easier.The result was the following list of grants and bounties (all of which are now available).Java Contract standards and templatesWhile we have been working internally on standard Java “smart contract standards and templates” we need help expanding the breadth of these to include other common patterns in blockchain application development.Plugins for IDEsOur research has highlighted IntelliJ and VScode as popular among Java developers, but we acknowledge that there are many more IDEs preferred by the community (apparently there’s a huge bunch of you that still use VIM). We need to build plugins that aid in syntax, linting (class library restrictions), debugging, local deployment/testing, and more. If you’d like to help get coverage on more IDEs, let us know.Command Line InteractionAn easy way for devs to interact with their contracts through the command line. Specifically, compiling, testing, and deploying to the test-net.Build Tool IntegrationsGradle, Maven and stand-alone utils.Other misc workflow improvementsAre we missing something? Feel free to let us know what you’d like to build!👇Aion Blockchain Bounty and GrantsLike building developer tools? was originally published in Aion on Medium, where people are continuing the conversation by highlighting and responding to this story.

Wandx is launching the following products: Aion Coin with Ledger integration within the WandX wallet, a decentralized exchange that has a unique feature called Basket Protocol and node infrastructure for decentralized applications.WandX: A decentralized exchangehttps:/ is organized around the idea of creating smart crypto-instruments for the new-age crypto trader. And to that effect, WandX is building a robust, decentralized multi-blockchain DEX-based trading platform powered by a proprietary Bakset Protocol. WandX’s basket protocol allows token traders to create a composite “basket” of tokens on smart contracts, tradable at one go. This way of token trading helps hedge risks and better manage one’s portfolio of crypto tokens. With the rapid tokenization of the global economy, the key to crypto success will depend largely on the ability of new age crypto asset holders to transact, transfer, and trade easily and smartly, and WandX is working to enable this ecosystem through smart crypto financial instruments.Abhinav RameshAbhinav is the Founder and CEO at WandX, a first-of-its-kind multi-blockchain DEX with a unique ‘basket’ trading protocol that allows one to buy into a collection of tokenized assets in a single transaction.

The Aion Foundation Report

Below is a press release and a link to our first Aion Foundation Report. But before you read it, we would like to briefly explain why these types of initiatives are so important.In 2014, the world was forever changed as a new funding model powered by crypto-currency offered enthusiasts of decentralization the ability to bootstrap the creation of a new ownerless web. Since then, more than 1,000 projects have been funded, and we’ve seen real incremental innovation that keeps us optimistic. However …There have been misstepsFor a variety of reasons, many of these projects have not, or will not, deliver on their vision - leaving members of these communities questioning the movement altogether. For those projects that are still building, many exist within a black box, and their future remains uncertain.What needs to change?We believe reform must come from within, which is why we’re designing and promoting a new standard in transparency and accountability for decentralized projects.We hope that the Aion Foundation Report serves as a meaningful example of good governance. It is also our hope that others follow in our footsteps to lift this technology out of the fog of consumer uncertainty and into an era of mainstream adoption.What’s in the report?Our report opens with a letter from Matthew Spoke, CEO and Co-Founder of the Aion Project and a Director of the Aion Foundation. Matt’s letter speaks to the importance of transparency and why the Aion Foundation has chosen to take this step.The report then goes on to outline the organizational structure and finances of the Aion Foundation, and discusses its role in the broader Aion ecosystem.The Aion Foundation leaned heavily on the wisdom of Deloitte to produce a report that it hopes will serve as a standard for accountability and transparency for the entire industry.How We OperateHave a voice in thisIf you’d like to be an active participant in this conversation, we’ve opened a question period on Reddit to field questions.

Signals from the Void — An ...

Signals from the Void — An IntroductionAdvancing dialogue on important issues in Web3One year has passed since the inception of the Aion Project. In the time that has passed, we’ve grown the project to a headcount that exceeds sixty in regions all over the world. We launched a test-net, and subsequent main network with active miners across the globe. We built the fastVM for increased transaction throughput and bridged the Ethereum Network to the Aion Network. More importantly, we’ve grown up, into an ecosystem of contributors, builders, and maintainers.Along this journey, we’ve been listening closely to our community. A strong signal has formed around the desire for more external inclusiveness into how we think about this space and our role within it. Operating as we have has provided us with the opportunity to focus on our work and deliver exceptional software, however, it has reduced the diversity of thought that comes from a community of stakeholders lending their perspective and opinions on subject matter that ranges from the non-technical to the uber-technical.In the coming months we have big milestones that we’re excited to share, and we’ve decided to publish more of our thinking around why these milestones matter, why we’ve made decisions in the ways that we have, what it means for web3 in aggregate and how you can get involved in the conversation.By communicating a variety of perspectives on technology, operations, marketing, security, engineering, ecosystem growth and more we hope to provide the community with a stronger sense of why we exist and how we view our role as early (but not permanent) stewards of the quest to rebuild a broken internet.When we first approached the community for support in launching the Aion Project one year ago, we committed not only to an unwavering focus on engineering excellence but also to a higher standard of accountability and transparency. In building the foundational technologies that will power tomorrow’s internet, we intend to embed these principles into our organizational DNA, as well as our system design. — Matt Spoke, Founder of The Aion ProjectStay tuned for more in this series of posts under “Signals from the Void” — advancing dialogue on important issues in blockchain.Signals from the Void — An Introduction was originally published in Aion on Medium, where people are continuing the conversation by highlighting and responding to this story.

Aion Joins Open Source Disc...

Messari, an open-source cryptocurrency-focused version of the U.S. Securities and Exchange Commission’s EDGAR database, is launching a disclosure registry for token-issuing projects to publicly share information that might otherwise be difficult to find.The Aion Network joins 11 other diverse, reputable projects all committed to transparency and self -regulation, in voluntarily disclosing basic information regarding our token design, supply details, technology audits, official communication channels, and relevant team members, investors, and advisors. These profiles can then be freely accessed industry-wide, providing a reliable, standardized resource to industry participants that is nonexistent today. Such basic data standards can facilitate diligence processes for crypto service providers like exchanges and wallets, retail and professional investors, and regulators alike.The Messari registry was announced at CoinDesk’s Consensus event and with the launch token projects will finally have a common platform that helps them better communicate material updates with both their existing communities and external stakeholders in a single, standardized interface.In its initial stages, the Messari team will on-board the projects themselves and facilitate disclosure accuracy. However, as the system grows the model will become a self-sustaining platform. Data on the registry will be publicly available, and Messari will even have an open API for free access to the disclosures.“The purpose of documented blockchain transparency is to move our industry towards true accountability” said Matt Spoke co- founder Aion, “and we see this registry as an important step in this process”.As the Aion Smart Contract Platform continues to onboard exciting new DApps and projects, it’s important for developers to know that Aion believes in being transparent, ethical and purposeful in engineering excellence and building the future we want.Aion Joins Open Source Disclosure Registry was originally published in Aion on Medium, where people are continuing the conversation by highlighting and responding to this story.
