Project introduction

Existing block chains have been focused on the fact that they are not modified once they are written to the block, but their interest in the reliability of the input data is relatively low. It is a project that proactively verifies the information recorded in the block chain through the iCash protocol based on the Proof of Trust to provide confidence in data entry.

Blockchain is only half of ...

Immutable data itself is not as helpful as we thinkThe only reason that blockchain is innovative is because it takes data, distributes it, and uses unbiased code to make sure everyone plays by the same rules in keeping or changing that data. Immutable data storage — that’s it. Nobody can go back and say something was recorded when it wasn’t. The tokens, smart contracts, side-chains, lightning networks, automation, and hype, all stem from the “Trust by Computation” that makes recorded data immutable once it’s in a blockchain.So when we say that Blockchain is going to change industries, yes we’re right, but really immutable data itself is not as helpful as we think. While data storage in a blockchain is technically and mathematically trusted, there is still a significant obstacle in being able to actually use blockchain to innovate the many industries targeted.Primarily, what happens when you put the wrong information into an immutable record? Let’s not make the mistake of assuming that just because data is permanent, that it’s correct.An immutable ledger is not trustworthy if the data contributed to it is not reliable. What if, for example, you have permanently tattooed the wrong person’s name on your arm? It would actually better if the record was NOT immutable, so you could go back and change it when needed.The evolution of blockchain Smart Contracts opens new business opportunities by enforcing rules and automatically executing transactions when coded parameters are met. The parameters and the preset/agreed outcome are both stored immutably on the blockchain, waiting for a signal of its fulfillment to execute.A simple example would be the case where a Smart Contract is created to remit payment to a recipient when a particular action is done. Let’s say I’ll pay you 5 bitcoin to review this article. The Smart Contract would hold the parameter of “Review the article” and the outcome “pay 5 bitcoin”, and will automatically pay you the 5 bitcoin when you’ve reviewed my article. That means no more accounts payable/receivable processing — a huge potential cost saving for businesses!The ProblemWith just blockchain, Smart Contract parameters (and therefore payment) could execute erroneously, without parameters being met in the real world, i.e. you didn’t really review my article, just set up a bot to open the page and clap 4 times, but the smart contract would still pay you my 5 bitcoin. And because Blockchain is permanent and immutable, the invalid transfer of my 5 bitcoin would be irreversible.No sophisticated party [like myself] would take the kind of execution risk that exists today with blockchain. Many different bots can be created, or malicious actors in the real world with access to Keys or API’s, to attest to misinformation without proper systemic contestation, recourse or rectification.This raises a key question in the blockchain ecosystem: As Smart Contracts enforce predetermined outcomes, how can distributed consensus validate Contract settlement before it’s immutably posted to the blockchain?Given the nature and scale of the operations being executed, trustworthy inputs are crucial. The disconnect between real-world confirmation and Smart Contract validation is of primary importance for instituting daily and industrial applications of blockchain Smart Contracts.The other half (data input)To gain enterprise (and my) adoption of blockchain systems, they must be integrated with systems validating data input. While blockchain has great value, it still needs to be applied with the right systems and measures to make sure that its data is valid before being immutably recorded. As anyone working in IT can tell you, “dirty data is dangerous”. This has never been more true than in the case of Blockchain. For serious users to be able to trust Blockchain, they need a type of checks and balances for cases of misinformation or nefarious inputs, to ensure that Smart Contract inputs can be validated before being irreversibly recorded.In my case, before paying you my 5 bitcoin, I want the ability to contest settlement if necessary, and have it validated. Because the contract parameters contain a live, verifiable event, there are a large but finite number of actors that could validate (or contest) the event actually happening. Incentive mechanisms must be put in place for immediate and long-term effects ensuring the distributed participants can be trusted on a larger scale.The SolutionDigital [nonhuman] inputs like RFID or satellite feeds can help, although even these technologies are not tamper-proof. Human actors in expert networks that have financial and reputational stake can help, although people work in erratic ways at times. So, as with most real-world solutions, the real answer will likely be a combination of both.The team at iCash saw this opportunity and set out to create it.iCash proposes the Proof of Trust (PoT) protocol to allow distributed validation of Smart Contract inputs, to be able to ensure, and potentially insure, valid settlement.PoT works concurrently with any blockchain system as a mechanism for assessing, auditing and affirming data inputs to execute with distributed trust. The integration of iCash’s PoT in the technology stack of IoT data sharing bridges the critical gap left between real world inputs and blockchain’s immutable records.With a network of accountable participants acting as decentralized oracle inputs (Delegates), PoT uses an algorithm to create, monitor, and report reputational trustworthiness over time, along with financial stake on majority consensus. Delegates can be both digital and human inputs. Smart Contracts are broken down to binary logic and voted on for majority consensus before being executed on the blockchain. To reach validity probabilities of a near-zero chance of incorrectness, Users are given the ability to contest even the Consensus determination of the Delegates and raise the query to SuperDelegates who have proven perfect reputation by always inputting correct determinations.This development aims to support reliable institutional services within a decentralized framework, and take full advantage of the trust and efficiency that blockchain has the potential to avail. By adding a layer of Trust to the application layer of data input, further advances in blockchain scaling and IoT device integration can realize the future we envision for technological development.The next article will address the different types of existing distributed oracle solutions proposed in the marketplace, and why iCash is uniquely positioned to succeed.Now that you’ve read and reviewed my article, I can send you the 5 bitcoin — just need your private key :)Blockchain is only half of the solution was originally published in iCash io on Medium, where people are continuing the conversation by highlighting and responding to this story.

5 Key Takeaways from Devcon4

Here I will cover the highlights of my trip to Prague for the Devcon4 conference. This conference was a showcase for all major players involved in building blockchain technology.I started off the day with an interview with Sasha at BIG Crypto about iCash. We covered a variety of topics: his entertaining story on how he first heard about the iCash team while at Consensus Singapore, an in-depth look at the most prevalent trends in blockchain technology, and how iCash will scale it’s Proof Of Trust (PoT) protocol for dispute resolution.We’ll be providing a link to the full video clip as soon as it becomes available.At the end of the discussion, I was asked to predict the 5 most important discussion points gained from attending the conference. I will now share those points after an amazing week of being surrounded by, and learning, from the best of the best. It should also serve to give readers a better insight as to the goings-on within the Cryptocurrency and Blockchain communities:1. The Future of Privacy and Scalability: ZK StarksZK StarksThe most packed talk of the conference was the Starkware lecture about ZK Starks.In a room that typically fits 150, I sat/stood with over 300 people crammed in to the space, listening and getting the firsthand knowledge of the latest development in ZK Stark technology.Meeting Starkware CTO Oren KatzI learned that they have a partner program where Starkware actively helps projects design their protocol. Oren also asked me more about how iCash uses ZK Snark technology to build the privacy layer for smart contract contestations.Starks will be commonplace, and a scaling solution for Ethereum. Given the right partnership opportunity, we would not hesitate to build our tech robustly to be the best long term dominant solution.2. The need for Decentralized TrustCongress Center, Prague, Czech RepublicHandshake (HNS)I noticed a rising interest in Decentralized DNS. There seems to be a recurring theme that a secure network system should be built with proper first principles.In order to truly decentralized the internet, built from the ground up using first principles; trust must be established at all layers in the protocol stack starting with root.In the case of HNS, the root or backbone of their protocol is the Domain Name System.This idea has been around since the early days of Bitcoin. Handshake (HNS) is a relatively new project headed by Joseph Poon that has both raised significant funding - as well as donating generously to open source software foundations that have been around since the early days.I learned that it exists today as a fork of bitcoin with a different approach to mining:Handshake works seamlessly with the existing DNS system. The domain names of the top 100,000 websites on the internet are being set aside for their legitimate owners to claim on Handshake [3].Handshake PaperThe fundamental issue that Handshake is solving is that in order to trust any website, one must also trust the Certificate Authority that generated the TLS or SSL certificate that validated the authenticity of that particular website to the user’s browser.Ethereum Name ServiceEthereum Name Service (ENS) is the domain name service that gives an alphabetic character name to your Ethereum address or dApp. They announced that apart from the .eth domain, two other top-level domains (TLDs) are becoming available in the next weeks: “.xyz” and “.luxe” are purchasable via traditional DNS registrars.At the Congress Center in Prague, bright and early overlooking the 2nd floor.Origin ProtocolWe talked about a mechanism which enables smart contracts to allow interactions from reputable people. They have submitted a proposal for ERC725 tokens to allow for that trusted transfer.Origin Protocol Co-Founders Matt Liu and Josh Fraser.Day 1 Closing ThoughtsIn order to truly decentralized the internet from the ground up using first principles, trust must be established at all layers in the protocol stack starting with root.Therefore, for Smart Contracts to be fully trusted and decentralized, they too must have a protocol to secure incoming and outgoing data (parameters, execution logic) such that the authenticity or validity can be proved in a deterministic manner. In light of this, there exists a deterministic way to contest and reclaim value that otherwise would have been lost.A blockchain system must properly decentralize trust in all layers in the protocol3. Vitalik Buterin TalkDevcon4 Day 2, the future of EthereumVitalik talked Ethereum 2.0 (Serenity), and the centerpiece of his talk was about a blockchain system called the “beacon chain”. The beacon chain is the “main chain” of the PoS system.Devcon4 Day 2, 10:45 am, main stageThe beacon chain’s 3 core functions serve to:Store and maintain the set of active, queued, and slashed validatorsProcess crosslinksProcess its own block-by-block consensus, as well as the finality gadget.My notes for the talk:Vitailk Buterin SpeechWhat this means for iCash is that we are on the right track. I’m getting confirmations from multiple sources, such as my in person meeting with Parity VP of Product, that Beacon chains and relay chains are the future of scalability in the near term.The Smart Contracts of the future will be more likely written eWASM over Solidity.eWasm is based off of WebAssembly(Wasm), a new Assembly standard being built for the web. The main advantage of using Wasm is performance (both speed and size).Wasm is a kin to LLVM IR and Low Level Instruction Set Architectures (ISAs). It is an defined as an Abstract Syntax Tree (AST) which has a textual representation using s-expressions. As an AST it has some higher level semantics than pure hardware ISAs. Including functions and basic flow control. Wasm is not finished a specification and still in flux. This EIP suggest using a subset of wasm to allow us to tailor the semantics to Ethereum. This spec is designed so that the minimum amount of changes a wasm VM would need to be implemented. This should make existing implementations of wasm easy to integrate and provide a way to run Ethereum-flavored wasm on an unmodified wasm VM.Source: EIP-140The EIP first came out in May, since then it has been additionally pushed forward by Dr. Gavin Wood (Ethereum cofounder) and his team at Parity. eWASM will make Smart Contract development more secure, cheaper, faster to develop (being able to re-use existing libraries that have been around for 30 years), and most importantly, will improve runtime performance of the Ethereum Virtual Machine (EVM).4. CTO Investor DinnerI participated in an exclusive dinner for blockchain CTOs during Devcon 4.There I led a discussion on iCash’s Proof of Trust Protocol, dispute arbitration and its importance in the ecosystem, how Security Tokens bring extreme value to user-based, top-down platforms built on blockchain, securities in blockchain, and more.What went downThis event brought together the best and brightest of the space, to enjoy a night away from the hectic schedules of Devcon 4 attendees. It created an intimate setting where after every conversation, a CTO could walk away feeling like they could freely express their ideas and learn from each other, without the daily pressures of business and competition.Devcon 4 CTO & Investor DinnerAttendee thoughtsFrom left to rightEugene Joo, CTO at Blockcrafters CapitalZane Witherspoon, CTO at Dispatch LabsIt was really great to discuss the idea of network liveliness with the VP of Eng of Algorand and technical leads of different investment firms~ Zane Witherspoon, CTO at Dispatch LabsMakoto Inoue, CTO at Ethereum Name Service (ENS) and Kickback center leftMesbah Sabur, Cofounder of Circularise center rightI talked with Makoto from ENS team and talked about its use case for IoT. The ENS team was interested in discussing my suggestion for IoT further since ENS team is concurrently looking for added use cases.I am planning to reach out to Nick Johnson to talk about this. Circularize CEO and I had very interesting conversation on implementation of blockchain to build circular economy, and he is looking for blockchain network to develop it. He might come to Korea next year in March where a future relationship can be nurtured.~ Hyungsuk Kang, Ethereum Foundation Research Scholar5. Adoption and PartnershipsAlgorand MeetupAlgorand is a first-of-its-kind technology that fulfills the promises of blockchain technology, through a platform that solves the “blockchain trilemma” — offering the decentralization, scalability and security necessary for both businesses and developers. They are often compared to Dfinity (a well-regarded decentralized and high throughput blockchain).Meeting with their Algorand founder Silvia and VP of Engineering Naveed discussing the technical details of their projectAlgorand sees themselves as a platform that can handle accounts and transactions as well as smart contracts. Their founder is an MIT professor who actually came up with the concept and methodology of their consensus 20 years ago. Algorand may be a public permission-less blockchain (that can be configured to be private permissioned) that can handle the scale and complexity that we require at iCash. We also agreed that projects like Algorand are always proactively looking for end use-case DApps and Protocols to be built on their platform.Currently, they are in the infrastructure phase. They need desktop wallets, mobile DApps, DEX’s, Centralized Exchanges. Currently their testnet supports sending (signing) and receiving Algorand native currency transactions. It also supports their model of non-binding provably fair staking method of block production.ConclusionThere will be ideas exchanged, and partnerships forged, that completely change the trajectory of the space as a whole. With many of the best and brightest attending this event, I’m grateful to celebrate and learn from this collection of amazing human beings as we move blockchain technology one step closer into the mainstream.5 Key Takeaways from Devcon4 was originally published in iCash io on Medium, where people are continuing the conversation by highlighting and responding to this story.

Beginner’s guide to Proof o...

Trust — it’s one of the promised attributes of the Blockchain. While most have proven useful to ensure trust between parties, not many have addressed the issue of trusting oracle inputs into a Smart Contract. With hopes of wider Blockchain adoption, trust is becoming an increasingly necessary component.Blockchain and Smart Contracts are fairly secure technologies to store and execute diverse information. An innate, immutable environment without any central authority or intermediary is regarded as the biggest advantage. But not enough attention is paid to the negative impact of incorrect or malicious data.What happens when a Smart Contract is executed based on manipulated, or faulty inputs and the result is forever recorded to the Blockchain?iCash’s Proof of Trust Protocol was born from that logical skepticism; to enable real-world inputs to be validated. After a party in the Smart Contract contests an outcome and requires adjudication, the PoT Protocol evaluates and pre-validates the information entered into Smart Contracts to safeguard transactions ranging from a few bitcoin to thousands of them.Here’s How the Proof-of-Trust Protocol WorksA layer, or stage, of the PoT protocol is added to a Smart Contract. Whenever data input is contested by one of the Smart Contract parties, a decentralized network of qualified participants validate the data before the execution of the contract. Those participants, called Delegates, could be a person, a group, or a company, with the relevant proven experience to provide validation.To ensure accountability, each Delegate must go through an agreed-upon KYC process. Once on-boarded, Delegates will be able to use a dedicated internal portal to set up open APIs for database query/responses like below. iCash admins may also use this portal to send notifications or inquiries to the Delegate community. With total anonymity to prevent collusion, Delegates stake their iCash tokens and reputation each time they take on contract adjudication.Delegates are asked to escrow iCash Tokens which are used as collateral in a familiar PoS fashion, but relative to the size of contract that they may adjudicate. For instance, a Delegate that escrowed 100 iCash Tokens when on-boarding may participate in validating a contract worth 1,000 iCash.What incentivizes the Delegates to take part in the majority consensus is the Reputation reward. Based on the result of voting for each Smart Contract query, a Delegate’s Reputation can either be retained or degraded. Fluctuating Reputation directly impacts financial reward and input capability for future contracts. For example, Delegate 1 in the case below will receive more rewards than others for maintaining the perfect Reputation.This algorithm also “punishes” a Delegate with the wrong input by lowering his/her reputation score, hence significantly reducing the rewards the Delegate receives. If a Delegate’s reputation score is below 75% then they cannot participate in any validation until certain time and tests have passed.SuperDelegates, on the other hand, are actors in the PoT network with impeccable reputation by always inputting consensus-driving Smart Contracts determinations with close to one hundred percent accuracy. SuperDelegates have reputations in the highest percentile and they maintain their rank by voting honestly consistently over time. To reach even lower chance of incorrectness, this additional layer would provide indelible majority consensus, and thus be considered valid.Delegate selection is random, which means it is exploit and collusion resistant. The specific Delegates that will execute the contract will be chosen by a combination of reputation, their escrowed stake, and the chronological order in which they entered. Optimized for gamification, the iCash Delegate selection is similar to the Uber model, in which Delegates are rewarded based on honest behavior.While many corporations have been searching for opportunities to utilize this new technology, there has been a risk of trust. Automated, immutable processes of Smart Contracts with possibility of loss cannot be trusted, or at least not until the data input is proven trustworthy.Collective intelligence to assure the validity of Smart Contracts — it’s the perfect solution.The iCash teamBeginner’s guide to Proof of Trust was originally published in iCash io on Medium, where people are continuing the conversation by highlighting and responding to this story.

Processes for Arbitration o...

The Importance of GovernanceGovernance is one of the unsung pillars of the blockchain. Along with the other core pillars such as scalability, privacy, security, and decentralization, some would say governance is the most important problem to solve. Governance pertains to a blockchain ecosystem, in which a near perfect process is in place that allows automation and a self-sufficient economy to survive. Many have come up with variants from the initial Proof of Work to Proof of Stake, Delegated Proof of Stake, Federated Byzantine Fault Tolerance, but we are at a stage where evolution is occurring and there has yet to be a winner.With the many pillars such as governance and decentralization that Blockchain Technology is comprised of, there is a shift from traditional structures to transact in new ways that previously required trust in a centralized entity. Blockchain solutions with the most efficient governance will be the most trusted, thus the most dominant and widely accepted.Blockchain Governance IssuesRecent issues around EOS have emphasized how challenging the governance issues may become. EOS was built on four pillars: flexibility, usability, governance, and scalability; of which, the governance pillar was tested foremost.Certain users fell victim to a phishing attack, they, in turn, sent private key information resulting in stolen funds. In response, the EOS Core Arbitration Forum (ECAF) alike to a centralized government body, directed block producers to not process these transactions without supplying logic behind such decisions. EOS attempted to resolve issues by offering to take back power from ECAF, furthering confusion.Processes for Arbitration on Smart ContractsThe blockchain community criticized the ECAF for overstepping their boundary on what they could enforce in the EOS ecosystem. Initially, they were only responsible for arbitrating on decisions guiding the direction of the EOS blockchain as a whole.Now, having the power vested in ECAF to vote on whether individual transactions may take place effectively goes against the basic decentralized decision-making process which blockchain was meant to address.Following this event, Dan Larimer proposed a revised draft of the EOS Constitution. He stated that arbitrators shall extend only into disputes regarding the intent of the code, as opposed to overseeing users’ assets.In a world where protocol-level dispute resolution is limited to fixing bugs in the code, how does one protect against fraud and theft of keys? The answer is to opt-in to a banking Ricardian contract which controls the tokens on behalf of their owners.Transfers within the Smart Contract are subject to dispute resolution where the contract-appointed arbitrators have the power to reverse transactions and freeze tokens. Any withdrawals from the banking Smart Contract would be subject to a 3-day delay after which it would not be reversible.Furthermore, he revised the EOS constitution to incorporate the following changes:If there is a dispute on the intent of the code, then intent shall be determined by a supermajority vote of elected producers or an arbiter mutually agreed to by the parties to the dispute and enacted by producers. A supermajority may, at their discretion, freeze a contract during an active dispute until such time as the code to fix the contract is available. The parties to the dispute must produce proposed replacement code. The producers may charge a fee and/or place other requirements on the parties to the dispute. A supermajority is defined as 2/3+1.The Impact of ArbitrationArbitration is a process of dispute resolution between two parties, led by an independent third party. The third party can be one or many arbitrators. The goal of arbitration is to obtain a fair resolution of the dispute without unnecessary costs or delays. Generally speaking, the dispute may arise in any situation. One common example is when business A has a written agreement with business B, they dictate the terms into the contract. When the contract needs to be enforced, the arbitration clause comes into play.As most people understand Smart Contracts being self-executing that the terms of the agreement are represented by lines of software code; in the advent of blockchain technology, we imagine permissionless Smart Contracts shall quickly replace traditional contracts. Discounting a few examples (e.g., contracts used for raising capital) for the vast majority of contracts, this has yet to come true.Hereinafter, to illustrate a few examples. A Services Agreement is a contract used for employers to set forth terms and conditions for vendors or contractors. It seems from a first glance that blockchain Smart Contracts would be a perfect use case for a decentralized Upwork. Using continuous integration, a bounty is placed on a company’s open source Github. When a developer successfully creates a pull request that passes all of the verification tests, that developer is paid out the bounty automatically by the continuous integration system. All of these events are verifiable on the blockchain — so why hasn’t it become a prevalent use case yet?At some point, human intervention is required in deciding whether certain terms have been satisfied for a subjective and just stance. For instance, our software service, even if the verification tests passed, the submitted code could still be of poor quality, runs slowly, or simply does the bare minimum in order to pass the tests. Successful service marketplaces such as Airbnb and Uber thrive on the fact that it is very simple to computationally verify whether a driver has driven from point A to point B or, whether a residence had a vacancy for guests. When verification is easy, quality of service can be standardized and the app becomes capable of solving problems on a global scale. When verification is challenging and without human’s discernment, self-executing contracts would still miss a crucial piece that renders them successful in the supposed decentralized world.iCash’s Proof of Trust (PoT) Protocol is an Automated Arbitration Mechanism that is Subjective in Nature and Objective in Function.iCash2–1There are countless amounts of contracts that require subjective human intervention. A Smart Contract for an insurance policy with a single input source in verifying whether an event (e.g., natural disaster) has occurred is one example which demands human intervention.A financial derivative contract requires an accountable party to give the closest floating point precision price for the underlying asset at an exact moment in time. Both of which are multi-billion dollar industries.At iCash, our vision is to bridge the gap between subjective and objective Smart Contracts using automated arbitration. iCash’s Proof of Trust (PoT) protocol arbitrates conflicts before events are verified and prior to being recorded on the immutable blockchain. This allows for contestation before settlements deemed irreversible.Who verifies these inputs? A network of Oracles being delegates that have a proven legitimacy. They are incentivized by the financial gain in verifying the Contract and held accountable via staked iCash tokens and in the KYC registration process. These delegates are ranked and tracked by an algorithm that ensures consistent performance of these delegates. This way, trust is distributed among trusted agents creating a happy medium in the decentralized world with a system of checks and balances without having the power be vested in ECAFOnce parameters are entered into a Smart Contract on the blockchain, 50 basis points (in iCash tokens) are placed into an escrow. If there is no contestation to the initial determination of the Smart Contract, then it enters into the blockchain; and, the funds in escrow are released back to appropriate parties.If the original Smart Contract determination is contested, the matter is elevated from the Smart Contract, and a full network call is incited. In this case, 25 basis points are paid to delegates. These delegates validate the data in a Boolean voting process (i.e., True/False, 1/0).If there is no agreement, a second layer of contestation would take place, wherein delegates with the highest trust score (called SuperDelegates) for a given Smart Contract domain will then vote again to reach consensus. If approved by these SuperDelegates, then the prior arbitration is overturned. The decision of the SuperDelegates is what’s ultimately recorded on the immutable ledger.Based on correctly voting, delegates are given a PoT score on their accuracy. The vision of the iCash team is to enable delegates in providing non-binary or continuous data entries and determinations with respect to probabilities. These determinations become automated, requiring minimal intervention, and offer scalability.Conclusion: Blockchain’s Governance Authority and Decentralization OutlookWe have seen that this key value of blockchain can be a double-edged sword. Both EOS and Ethereum have identified that it is of utmost importance for transactions to flow freely without a central authority. As Smart Contracts increase in complexity and prevalence, we will continue to witness this issue being tested. It is an issue of where one draws the line between having a secure user experience v.s. true decentralization.In June 2016, Ethereum’s governing body, the DAO was compromised and millions of ether were stolen from a Smart Contract. That smart contract was intended to operate a certain way; however, due to human intervention (quite literally) it was exploited and operated in a way that directly goes against the contract’s intended purpose. Like EOS, Ethereum’s core members made the decision to reverse the transactions of the stolen ether, and effectively overstep the system of checks and balances.During this process, the major decisions on governance shall be created, and many more prior decisions will likely be overturned. These situations will continue to occur as the blockchain community matures and properly defines the standards for governance. Through the process of clearly defining the factors for which each decision is judged on, we utilize prior decisions as precedents to assist in assessing future decisions. This is the start of a standardized process, meaning having a protocol for arbitration, where we make a decentralized arbitration offer consistent, transparent and impartial settlements. With reliable decentralized arbitration, we can then trust Smart Contracts to operate as intended. The Proof of Trust protocol is built so that blockchain governance can evolve to fully exemplify the fundamental values of the blockchain.In essence, iCash is able to protect users from nefarious data inputs having incorporated a layer of trust and assurance inter-operable across the Smart Contract blockchains. Confidence in the system is hence achieved, paving the way for widespread adoption.Author: Ling Meng, CTO iCashProcesses for Arbitration on Smart Contracts was originally published in iCash io on Medium, where people are continuing the conversation by highlighting and responding to this story.

With all growth stories there are tales and times of struggle. Purity is beautiful, motivating, and timeless in its seductive allure. It also limits growth. The meteoric rise of Crypto and the Blockchain has, perhaps inevitably, produced simmering debate between growth and purity.We at ICash see both sides of the debate, and even internally, we have key players that lean in the two opposite directions. The siren song of a secure, immutable web, freeing folks to commerce, anonymous, rule-based engagement, and expanded access and transparency, is loud and sweet. Broadening and deepening this to include billions, presently underserved is a powerful draw as well. But, there is that trade-off between purity and reach?iCash is dedicated to building out the community. Our Proof of Trust protocol seeks to deliver speed and assurance of smart contract input accuracy. Why? Our experience, research, and advisory network have turned our eyes to a key and underexplored area. Distributed ledgers are potent, efficient and secure at recording and securing information. This has broken open a wide range of new possibility and opened access to billions.However, there remain real and pressing issues with what we are chiseling into the digital tablets. Before we make it indelible, let’s make sure we make sure it is correct. Solving for accuracy in inputs to ledgers and facilitating fast and low cost transactions brings diversity and scale to Crypto.Adding a layer of verification and authentication offers a major stride forward for the distributed ledger. There may be an increment of sacrificed purity. To absolutely minimize the loss of purity, we strove to use trust — not simply sanction — to build veracity of input and ability to appeal outcome. The trust layer means faster, further and greater use of distributed ledger. Yes, there is a touch of centralization in selecting criteria and voices to serve as assurance of accuracy and ability to appeal inputs. We think a simple, transparent and artful layer of trust building can largely preserve decentralization, while vastly increasing the community. Hence, Proof of Trust was born.Our CEO likes the turn of phrase, measure three times and cut once. Proof of trust is this philosophy in digital action. We have been building scoring and sorting capabilities to allow fast, inexpensive, and secure data. We have also begun to build. We would love to add you to the community. We may not have achieved purity, but we act with purpose.Building Out from the Secure Core was originally published in iCash io on Medium, where people are continuing the conversation by highlighting and responding to this story.

What is the Global Blockcha...

Despite Blockchain’s decentralized nature, there are several areas vying to be Blockchain hubs. Even though New York granted only the fifth Bitlicense in existence recently, the city is quickly becoming the leading global hotbed for Blockchain tech and commerce.Yet, there are other locales vying to be the next hub including Silicon Valley, Chicago, Austin, and Boulder. Blockchain, also known as Distributed Ledger Technology (DLT), is looking to set up shop elsewhere with Bermuda, Seoul, Hong Kong, Tokyo, as well as Estonia and Malta, all emerging as prominent contenders. It seems Blockchain technologies are more mainstream overseas than they are in North America.In order for the movement to legitimize itself in the eyes of institutions, it must have a settled and acceptable regulatory framework. The biggest problem market participants and potential entrants face are the seemingly ever-changing decisions regarding jurisdiction and enforcement, as well as different regulatory agencies producing diverging guidance. Here at iCash, we operate in multiple jurisdictions and presently work with 25 different law firms across the world. In close concert with these advisers, we constantly strive to adhere to regulations that are in flux.These regulatory decisions will have far-reaching network effects. Geographies with regulatory clarity and consistent guidance will see higher capital inflows and larger numbers of Blockchain businesses, largely because these jurisdictions are trying to solve a big sector issue. Market participants that are drawn to these locales involve everything from Blockchain users, exchanges, firms, along with hedge funds bringing innovation, employment, tax revenues and media attention. The question as to whether or not “Blockchain is going mainstream” is being answered every day in dollars and cents.We think going “mainstream” — both in terms of intention and applicability — are two different things. DLT’s applications, acceptance, and mainstream use are certainly gaining momentum, and this is a development we are at the forefront of.Blockchain topics now have an entire slot on the calendar as evidenced during New York Blockchain Week, evolving from singular events like Ethereal and Consensus 2018.Today it is no longer a question of “if”, but rather “when” Blockchain goes fully mainstream, and the answer is growing increasingly apparent. The more people living outside of our “Blockchain world” who can understand “What is Blockchain?” and “What is cryptocurrency?”, the greater the certainty we all have knowing that this movement will become widespread and embraced globally.To learn more about our Token Offering, visit us at iCash.ioWhat is the Global Blockchain Community? was originally published in iCash io on Medium, where people are continuing the conversation by highlighting and responding to this story.

    세일물량 미판매분은 소각하나요?

  • 맥쓰봉 Nov 22. 2018

    상장하긴 하나요?

  • odyssey9 Nov 12. 2018

    아직도 출금할수가 없는데 ... 무슨 이유때문인가요?

  • 갓동이 Oct 26. 2018

    11월 초 거래소 상장이 확정되었다고 지연될일이 없다고 하지않으셨나요??
    리퀴드거래소에서는 왜 프리세일기간이 지연되고 늘려진거죠? 해명바랍니다

  • 갓동이 Oct 12. 2018

    아래질문의 예전 정정 답변입니다...

    안녕하세요. 정정드립니다.

    총 발행량 : 2억개 (200,000,000)
    하드캡 : 8천만개 입니다. (80,000,000)

    총 발행량의 40%는 세일 물량으로 진행됩니다.
    8천만개가 세일수량이며 프라이빗 물량이 포함되어 있습니다.

    자세한 내용은 백서 확인 부탁드립니다.

    iCash Person in charge Oct 12. 2018


    10억개 중 2억개가 실제로 유통될 물량입니다.

    하드캡을 수량으로 안내한 점 실수가 있었습니다. 정보 확인에 혼선을 드린 점 죄송합니다.

    아래의 질문에도 답변드렸습니다.
    확인 부탁드립니다.

  • 갓동이 Oct 12. 2018

    자꾸 답변이 바뀌어서 마지막으로 재 질문드립니다.

    1. 총발행량 (토큰개수)

    질문에 보시면 젤처음에 총발행량이 10억개라고 하셨다가, 정정이 2억개라고 하셨다가, 또 다시 10억개라고 하시면 너무 혼동이 되네요..
    금액 말고 토큰 개수로 정확히 총발행량이 몇개인지 말씀해주세요.

    2. 하드캡 (토큰개수)
    정정 답변보시면 또 8000만개의 토큰이라고 말씀하셧는데 이제와서 왜또 8000만불 상당의 토큰이라고 말씀해주시는지요?? 그럼 최대 유통량이 900억 규모가 맞나요??
    정확한 갯수를 알려주세요... 금액 말구요..

    iCash Person in charge Oct 12. 2018

    커뮤니케이션 문제가 있었던 점 사과 드립니다.

    먼저 하드캡/소프트캡은 금액입니다. 저희가 갯수로 표시한 점 사과드립니다.

    토큰 전체 발행량은 10억개 입니다.
    그중에서 20%인 2억개가 실제로 유통되는 토큰이구요. (나머지는 보험등의 용도로 쓰입니다).

    20%에 해당하는 2억개 중 40%가 퍼블릭 때까지 목표 판매 수량입니다.(총 8000만개)

    이번 세일
    하드캡은 $2500만 USD
    소프트캡은 $1250만 USD 입니다.

    1달러 기준으로 토큰갯수를 적용하면 대략 이번 세일을 통해 4천 250만개가 풀리게 됩니다.

    프라이빗 및 프리 때 토큰은 할인된 가격으로 판매되어 수량이 다를 수 있는 점 양해 부탁드립니다.

  • 갓동이 Oct 12. 2018

    총발행량 및 하드캡질문다시드리겠습니다..
    밑에는 총발행량 2억개 하드캡 8천만개라고하는데요
    분석리포트 항목에서는 소프트캡 1250만개
    하드캡 2500만개로 표시되네요
    이번 프리세일에서만 하드캡이 2500만개고,
    전체로 봤을때 총하드캡이 8000만개라는거죠?

    iCash Person in charge Oct 12. 2018

    네 총 하드캡이 8,000만불 상당의 토큰입니다.
    이번 세일의 하드캡이 2,500만불 상당의 토큰이구요.

    보통 캡은 금액으로 표시됩니다.

    다만 세일 하드캡은 8,000만불이며,
    토큰 가격은 1불로 측정되어 있습니다.

    마감된줄알았는데...아직 파네요!
    사려다 계산이 복잡해서 여쭈어봅니다

    토큰뱅크에서 처음 토큰구매하려는데 이더리움으로 사는게 낫나요? 이오스로 사는게 낫나요?
    원화 100만원으로(이오스 또는 이더리움 지금시세)
    아이캐쉬 사면 갯수로 몇개 오나요?

    iCash Person in charge Oct 08. 2018

    안녕하세요. 7일자로 판매 종료되었습니다.
    추가적으로 10일부터 아이캐시 추가세일이 진행될 예정입니다.
    보너스 비율은 이번 세일과 동일합니다.

    1-1차 500 ETH
    1-2차 1,500 ETH

    아이캐시 구매 비율은 이더와 이오스 동일합니다!

  • 갓동이 Oct 08. 2018

    음 갑자기 프리세일 기간이 10/05 ~ 10/07 까지였는데...
    10/10일 까지 연장된 이유가 있나요??...
    설마 ICO 기간도 연장되고... 거래소 상장도 연기되고 그러는거 아니죠? ㅠㅠ

    iCash Person in charge Oct 08. 2018

    안녕하세요. 7일자로 판매 종료되었습니다.
    잠깐 세일 기간이 연장된 것은 저희측 오류입니다.

    추가적으로 10일부터 아이캐시 추가세일이 진행될 예정입니다.
    보너스 비율은 이번 세일과 동일합니다.

    1-1차 500 ETH
    1-2차 1,500 ETH

    *상장은 이미 정해진 사항으로 변동 없습니다!

  • 갓동이 Oct 07. 2018

    프리세일 이후 ICO도 토큰뱅크에서 진행하시나요?

    한국은 판매량이 얼마안되네요 ㅠㅠ

    11월 글로벌거래소 상장 전 마케팅 좀 더 힘써주셨으면 합니다

    국내에도 아이캐쉬 카톡방 하나 있으면 여러가지 서로 홍보가 될텐데 아쉽습니다.
    구글 카카오와같은 대기업과 좋은 협력관계를 유지 하고있다는것을 많은분들에게 알려주세요!

    iCash Person in charge Oct 07. 2018

    안녕하세요. 11일부터 추가적으로 세일을 진행합니다.
