Oracles are a key part of blockchain infrastructure. They enable communication between the external world and on-chain environments in a trustless manner. Oracles are vital for many parts of the blockchain industry including decentralized finance (DeFi) and Web3 applications. An optimistic oracle like UMA's uses a “true unless disputed” pattern, with a tokenholder vote to resolve disputes. Anyone can propose an answer to a data request, and it is accepted as true if it is not disputed during a verification period. The “optimistic” design differs from a price-feed oracle, where prices are streamed on-chain and are instantly final. This optimistic oracle design concept has been in development since 2014, when Vitalik first published on the matter. There have been several iterations over the years since then. The optimistic design pattern introduces the opportunity for human intelligence to weigh in. This is important for Web3 projects as they require arbitrary data that is not always possible to turn into code. Today, the OO provides flexible, unique dispute resolution involving any kind of question or data with human input, as compared to price feed oracles, which can only push regular price updates onto chains.

UMA was founded in 2018 by Allison Lu and Hart Lambur, two ex Goldman Sachs traders, with the goal of making global markets universally fair, accessible, secure and decentralized. The team drew inspiration from traditional finance derivatives to define an open-source protocol to allow anyone, anywhere, to design and build trustless financial contracts.

WAX network’s DPoS consensus is secure against the corruption of a significant minority or producers. Token holders can select WAX guilds by voting in a continuous approval system. They can get an opportunity to produce blocks and token holders can persuade other token holders to vote for them. A block gets produced on the WAX blockchain every 0.5 seconds; as such, one WAX guild gets authorized to produce a block at any given point in time. If a block does not get produced at the scheduled time, the block for that time slot is skipped. When one or more blocks end up getting skipped, another gap in the blockchain of 0.5 seconds or more is added. WAX guilds do not receive WAX rewards if they produce 50% or less of the scheduled blocks, which discourages skipping blocks. WAX has created a full suite of blockchain-based tools that allow anyone to trade digital or physical items instantly and securely.

WAX (WAXP) has a circulating supply of 1,513,825,734 tokens as of February 2021 and a maximum supply of 3,770,303,327 WAXP.

WAX features a WAXP-to-Ethereum ([ETH](https://coinmarketcap.com/currencies/ethereum/)) bridge that allows WAXP token holders to convert their tokens into WAXE, which is an Ethereum-based ERC20 utility token. Users willing to participate in WAX tokenomics need to burn their WAXP tokens in order to get WAXE through the Ethereum bridge. They will then need to stake the WAXE tokens on the Ethereum distribution contract. WAXG is an Ethereum-based ERC-20 governance token that is distributed to WAXE stakers. The distribution is based on a set timetable and is proportionate to the percentage of the WAX Economic Activity pool. The token holders can govern the allocation and distribution of economic value on the platform as a result. The WAX Economic Activity pool is a smart contract that accumulates a percentage of generated WAX fees and can be converted into ETH for distribution to WAXE stakers. It can also be given to WAXG token holders that decide to burn the tokens they already have.

WAX was co-founded by William Quigley and Jonathan Yantis. William Quigley studied at the University of Southern California, and then worked at Disney. After leaving Disney in the early 1990s, he got an MBA at Harvard and became a venture capitalist. Over time, he became the managing director at Idealab. Alongside creating WAX, he is also the managing director at Magnetic. Jonathan Yantis works as the chief operating officer at WAX and as the chief operating officer at OPSkins.

WAX (WAXP) is a purpose-built blockchain, released in 2017, that is designed to make e-commerce transactions faster, simpler and safer for every party involved. The WAX blockchain uses delegated proof-of-stake (DPoS) as its consensus mechanism. It is fully compatible with EOS. The custom features and the incentive mechanisms developed by WAX are intended to optimize the blockchain’s utility specifically for use in e-commerce, with the goal of encouraging voting on proposals. To make this possible, WAX created a suite of blockchain-based tools which decentralized application ([DApp](https://coinmarketcap.com/alexandria/glossary/decentralized-applications-dapps)) marketplaces and non-fungible tokens can be built upon. Services such as WAX Cloud Wallet, SSO and OAUTH support e-commerce operations, the latter being a native RNG service and a developer portal. WAX’s blockchain architecture supports 500-millisecond block time and zero-fee transactions for customers. It also makes use of voting rewards to incentivize participation in the selection of block producers and improvement proposals.

As one of the earliest blockchain solutions, Storj’s token has liquidity. Over fifty exchange platforms have $Storj listed in pairs with other major currencies and cryptocurrencies, including [Coinbase Exchange](https://coinmarketcap.com/exchanges/coinbase-exchange/), [Crypto.com](https://coinmarketcap.com/exchanges/crypto-com-exchange/) and [Binance](https://coinmarketcap.com/exchanges/binance/). You can make a direct conversion of USD and Euro on [Kraken](https://www.kraken.com/) as well. Learn how other platforms are leveraging the Ethereum blockchain to drive innovation [here](https://coinmarketcap.com/alexandria/categories/blog).

Storj Labs Inc., uses its Tardigrade software installed on node computers to create and secure user data. This network of anonymous nodes removes the need to trust cloud storage service providers to secure the privacy of our data. The system is also peer-to-peer encrypted, which means that each file is encrypted before being dispersed to the network of independent hosts. Each node only receives a random fragment of a whole file with decryption keys split among each node and the host, making it almost impossible to hack. Node operators get rewarded for hosting data as well confirming the safety and retention of the hosted files randomly in a process known in the crypto world as mining ([PoW](https://coinmarketcap.com/alexandria/article/proof-of-work-vs-proof-of-stake)). The Storj token is used for this purpose. Individuals or organizations who want to store their data on the network provide the Storj tokens paid to nodes This system ensures that user data are protected against hacks and other malicious attacks. It also removes the risk of storing data in a few isolated data storage units — which can be subject to a planned, coordinated attack, leading to mass loss of user data.

Initially about 500 million [$Storj](https://storj.io/blog/categories/tokens) tokens were minted on the [Ethereum](https://coinmarketcap.com/currencies/ethereum/) blockchain. After Storj Labs hosted a token sale, 75 million of these were burned. Now the total tokens available in circulation is just short of 425 million. In 2017, before the token sale, the company locked up 245 million tokens in a reserve. The token sale itself had 70 million tokens released into circulation.

As a decentralized cloud storage network, Storj is unique in more ways than one. For one, unlike traditional cloud storage solutions that store data in huge data centers, Storj runs on a network of thousands of independent computers. Anyone with a few extra terabytes of space can become a node on the platform by installing Tardigrade. All that is required is a strong and consistent internet connection. The efficiency of the network means that hosts pay far less for the storage of their data than when employing traditional cloud storage services.

Storj was founded by Shawn Wilkinson in May 2014. Wilkinson was a software developer based in Atlanta. He saw how blockchain technology could be leveraged to build a decentralized cloud storage network. Together with his co-founder, John Quinn, the first white paper was published late 2014. Since then, the concept and details have changed. The current version of Storj, V3, was launched in the middle of 2019. In addition to being a blockchain enthusiast, Quinn had extensive background in business development. Prior to founding his own projects (including Storj) he had been involved in the investment banking industry. The concept was finally incorporated as a company — Storj Labs Inc. in May 2015. At the company’s inception, Wilkinson served as CEO. Later, he stepped down for a more experienced hand to take the wheel, with Ben Golub currently serving as CEO. Wilkinson is now the chief strategy officer (CSO), while Quinn serves as the chief revenue officer (CSO) as well as a member of the company’s board. The platform was able to raise 910 bitcoin worth about $460,000 in 2014 in a public crowd-sale. They raised $3 million in a seed funding round three years later and then held a token sale, generating an additional $30 million that same year.

Storj, pronounced as “storage,” is an open-source cloud storage platform. Basically, it uses a decentralized network of nodes to host user data. The platform also secures hosted data using advanced encryption. In a white paper published in December,2014, Storj was first introduced to the world as a concept. It was to be a decentralized [peer-to-peer](https://coinmarketcap.com/alexandria/glossary/peer-to-peer-p2p) encrypted cloud storage platform. Two years later, an updated white paper was published. Here, a decentralized network — connecting users who need cloud storage space with those who have hard drive space to sell — was described. The platform was launched in late 2018. People with hard drive space and good internet connectivity can participate in the network. They become a unit in the network, called a node. Space providers are rewarded by Storj tokens.

One of the most popular exchanges where API3 can be purchased include [Uniswap](https://coinmarketcap.com/exchanges/uniswap-v2/), where it is paired with Wrapped ETH. It’s also available against USDT on Huobi Global and KuCoin, and paired with ETH on OKEx and 1inch. [Learn more about how to convert fiat currencies to crypto in our handy guide.](https://coinmarketcap.com/how-to-buy-bitcoin/)

API3 is an [ERC-20](https://coinmarketcap.com/alexandria/glossary/erc-20) token, meaning that it’s based on the [Ethereum](https://coinmarketcap.com/currencies/ethereum/) blockchain.

As of January 2020, CoinMarketCap data suggests that there are 13,847,549 API3 in circulation — out of a maximum supply of 100 million tokens. While 15 million tokens have been distributed among pre-seed and seed investors, a further 20 million tokens were reserved for a public token distribution event that took place over the first two weeks of December. The founding team was allocated 30 million tokens, with 10 million going to partners and contributors. And finally, 25 million went to an ecosystem fund. Tokens sold during a public sale are unlocked, but seed investors and founders are subject to a vesting period of between two and three years.

In the world of blockchain and crypto, we all too often hear about projects that are aiming to bring this technology to established industries such as real estate and finance. One of the most compelling attributes of API3 is how it’s aiming to fix some of the problems that have emerged within the blockchain space itself. APIs are crucial because of how they supply blockchains with off-chain data — without it, these decentralized ledgers wouldn’t have a clue about how much coins should be worth. In setting out why API3 is unique, Vanttinen explained how decentralized APIs can “provide superior data transparency all the way to the factual data source level, compared to existing decentralized oracles, which do not consider the data source API to be within the scope of their solution.” Light and robust middleware called Airnode has been created to make API3 a reality — and the distinctive qualities of this tool concern how it can be deployed in minutes, enhancing transparency and substantially reducing transaction fees in the process.

Three people have come together to bring API3 to life. The first is Heikki Vanttinen, who has written extensively about the project and what it hopes to achieve. He previously worked as founder and CEO at CLC Group, a blockchain lab “developing real-world connected smart contract solutions for a more trustless, efficient and secure future.” Vanttinen also served as chief marketing officer at Zippie, a mobile operating system that aims to help blockchain technology achieve mainstream adoption. Vanttinen has been joined by Burak Benligiray. He also worked at CLC Group, serving as CTO. Benligiray has previously written posts highlighting the merits of ChainAPI, which serves as the integration platform for API3. This has been described as the “spiritual successor” to Honeycomb, which was one of the innovations that had been pursued by CLC Group. And last but by no means least, the third co-founder at API3 is Saša Milić. As well as serving as a sessional lecturer at the University of Toronto, where she taught core curriculum courses to computer science students, she’s also worked as a software engineer for Facebook, and as a simulation data scientist for Gauntlet.

Smart contracts often struggle to access dependable data, but application programming interfaces ([APIs](https://coinmarketcap.com/alexandria/glossary/api)) have been touted as a solution to this problem. API3’s stated goal is to allow decentralized versions of APIs to be built, managed and monetized at scales. As blockchain technology plays an ever bigger role in the economy — from decentralized finance to supply chain management — the team behind this project says it has never been more important for smart contracts to provide “timely, reliable real-world data.” The whitepaper for API3 was unveiled in September 2020 and set out the main problem that’s associated with APIs at present: connectivity. At present, there’s no way for smart contracts to establish a direct connection with APIs for the latest data — and this has led to an explosion in the popularity of oracles. Although this has helped solve the problem to some extent, the industry has since been grappling with the “Blockchain Oracle Problem.” Oracles are a form of middleware that sit in between APIs and smart contracts — increasing costs and centralization. API3 intends to get around this problem by enabling API providers to operate their very own nodes. API3’s token went live at the start of December following on from a token sale that generated tens of millions of dollars.

The VeChainThor network relies on a proof-of-authority ([PoA](https://coinmarketcap.com/alexandria/glossary/proof-of-authority-poa)) consensus mechanism, which allows it to validate transactions more swiftly. Not only that, the foundation of the blockchain is heavily influenced by the Ethereum Virtual Machine ([EMV](https://coinmarketcap.com/alexandria/glossary/ethereum-virtual-machine-evm)), and uses some of the main concepts employed by the Ethereum blockchain. VeChainThor is not built on [Ethereum](https://coinmarketcap.com/currencies/ethereum/), but is its own separate blockchain. The PoA consensus relies on approval from an Authority Masternode (AM), which is selected by the VeChain Foundation. Authority Masternodes have to disclose their identity and build their reputation before the VeChain Foundation approves them as a validator. Both VET and VTHO tokens are a special class of [ERC-20](https://coinmarketcap.com/alexandria/glossary/erc-20) coins, which means they are versatile and can be stored in a number of hot and cold cryptocurrency wallets.

What is interesting about the VTHO token is that it is directly derived from the VET token. In order for transactions to be processed on the VeChainThor blockchain, a part of a VTHO token is created for every VET token added to the block. In essence, this means that 0.00000005VTHO is generated per VET per block. The maximum VET supply is 86,712,634,466 tokens. Of this, about 74% represents the currently available supply, or close to 64,315,576,989. The VTHO supply is significantly lower at 31,946,532,533 tokens.

VeThor Token (VTHO) is unique due to the fact that it is a VIP-180 Standard token. While VeChain Token (VET) performs as the primary value-transfer token, VTHO is an inseparable part of the operation of VeChainThor. The bi-token design of the blockchain allows traders to participate with both tokens, thus diversifying their involvement with the project. The VeChainThor blockchain boasts increased processing speeds, and an open source design, allowing developers to pool together their efforts. In addition, VeChainThor developed meta-transaction features which allow participants to organize multi-party payments and multi-task transactions. This versatility allows enterprise users of all levels to benefit from blockchain capabilities. In addition, the VeChainThor network benefits from the dual token design, as transactions and [smart contracts](https://coinmarketcap.com/alexandria/glossary/smart-contract) are executed thanks to the VTHO token, which is not directly related to the market value of VET.

[Sunny Lu](https://twitter.com/sunshinelu24?lang=en) is the founder and CEO of VeChain. His professional career took several big turns. In 2009, Sunny Lu took a position as the IT Manager of Bacardi China. One year later, he turned his attention to the world of fashion, becoming the chief technical officer for Louis Vuitton China. In 2014, he switched over to the IT sector of the company, becoming the CIO of the Chinese division. A year later, in 2015, the idea for VeChain was born, and Sunny Lu founded the company. At first, VeChain was a subsidiary of one of the largest powerhouses in China’s blockchain industry — Bitse. Later on, Sunny Lu separated from Bitse, and VeChain became an enterprise of its own. In 2018, the company went through a significant rebranding process, which resulted in creating the VeChainThor blockchain and the VeThor token.

VeThor Token is one of the two tokens employed by the VeChainThor public [blockchain](https://coinmarketcap.com/alexandria/glossary/blockchain). VeChain was initially launched in 2015, but it went through a heavy rebranding process in 2018. While VeChain Token ([VET](https://coinmarketcap.com/currencies/vechain/)) is the native token for the platform, VeThor Token (VTHO) plays an essential role in the overall functionality of the blockchain. The VeThor Token is a VIP-180 Standard token, which represents the cost of using the VeChainThor blockchain. Its primary purpose is to facilitate processes and transactions on the blockchain, and it essentially represents the smart contract layer of the network.

# Grown-Up DeFi. The Cosmos Layer 1 platform for community selected projects creating true value. **Semi-Permissioned** In order for a contract to launch on Kujira, it needs to be voted in via governance. This ensures that the quality, sustainability and longevity of the network are protected. A tight-knit hub of revenue generating products with great UX. "Grown-up DeFi" is not a meme. **On-chain Scheduler** The on-chain scheduler allows protocols to be designed with much less of a reliance on bots. This means there are far fewer wasted transactions. Protocols can be designed to operate more efficiently, and fees which were once required to incentivize bot usage can go back to the users of the network. **Native Token Generation** Smart contract developers no longer need to handle two individual entry points into their contracts, only needing to design for a native denom. In doing so, every token on the network will be a native Cosmos token, and associated liquidation and trading revenue (with more to come) will all accrue to KUJI stakers. **Build with Cosmos SDK** Access the entire Cosmos ecosystem seamlessly in an environment with proven security and interoperability via IBC. **CosmWASM 1.0 Support** Leverage Rust’s expressive type system and Cosmwasm’s best in class architecture to fearlessly build safe and secure smart contracts. **Thriving Community** With 50K+ active users and a very engaged Twitter, Discord and Telegram community, this is a welcoming home to hit the ground running in. **Built to Last** A long term view for real-world use, revenue, and sustainability for builders, validators and users alike.

Launched on 04/04/2019 by a team based in the US, Canada, South Korea, Nigeria, and Estonia, Creditcoin aims to address the lack of credit system among the unbanked in the emerging market. People who cannot access the banking system have to borrow from non-banks. However, credit records with non-banks are not accepted by the banks since they cannot trust the data. The project aims to solve the problem by recording credit transaction history objectively on a public blockchain.
