You can build publicly auditable and trusted applications that run custom code, can talk to other services and are accessible through an API, all using a built-in user account system (optional) and real Lightning payments. Above you see a graphical example of a contract with two methods: bet and resolve. Account 74 made a bet with account 12 when both called the bet method (details of the contract and calls are hidden for brevity). Then later an anonymous oracle called resolve and settled the bet. Account 12 ended up with all the satoshis. Contracts are just that: a set of methods, some funds and a JSON state. Calls can be identified or not, and it can contain satoshis or not. -

TokenScript
Smart Token Labs
TokenScript will set a new standard for token composability in a Web3 future where tokens are as ubiquitous as web pages, and where tokens will become primary objects of ownership, identity and interaction. When dApps are used as the token interface, token utility is limited. Transaction and integration logic locked in the dApp layer brings the same composability, security and availability issues that existed in Web2. Token knowledge and smart contract logic in a portable interface dramatically increases token utility. This brings context, security, interoperability and composability to tokens - not dApps. With unlimited logic and endless composability, Smart Tokens will deliver the promise of Web3. A fully-integrated web. A truly frictionless market. -

Truebit
Truebit
Truebit is a blockchain enhancement which enables smart contracts to securely perform complex computations in standard programming languages at reduced gas costs. While smart contracts can perform small computations correctly, large computation tasks pose security risks for blockchains. Truebit counteracts this shortcoming via a trustless, retrofitting oracle which correctly performs computational tasks. Any smart contract can issue a computation task to this oracle in the form of WebAssembly bytecode, while anonymous “miners” receive rewards for correctly solving the task. The oracle’s protocol guarantees correctness in two layers: a unanimous consensus layer where anyone can object to faulty solutions, and an on-chain mechanism which incentivizes participation and ensures fair remuneration. These components formally manifest themselves through a combination of novel, off-chain architecture and on-chain smart contracts. -

Check out the many contributors, collaborators, applications, and backers that make up the Secret Network ecosystem. With blockchain technology, we have the potential to create a more empowering and inclusive internet, what is often referred to as Web3. But current blockchains are public by default, exposing all data to everyone and putting users at risk. In order to enable meaningful use cases and achieve global adoption, users and organizations need control over how their data is used and shared, a concept we call programmable privacy. -

Hyperledger Fabric
Hyperledger
Hyperledger Fabric is an enterprise-grade, distributed ledger platform that offers modularity and versatility for a broad set of industry use cases. The modular architecture for Hyperledger Fabric accommodates the diversity of enterprise use cases through plug and play components, such as consensus, privacy and membership services. Hyperledger Fabric is intended as a foundation for developing applications or solutions with a modular architecture. Hyperledger Fabric allows components, such as consensus and membership services, to be plug-and-play. Its modular and versatile design satisfies a broad range of industry use cases. It offers a unique approach to consensus that enables performance at scale while preserving privacy. One of the many compelling Fabric features is the enablement of a network of networks. Members of a network work together, but because businesses need some of their data to remain private, they often maintain separate relationships within their networks. -

Band Protocol
Band Protocol
Band Protocol is a cross-chain data oracle platform that aggregates and connects real-world data and APIs to smart contracts. Blockchains are great at immutable storage and deterministic, verifiable computations. However, they cannot access trusted real-world information available outside their networks. Band Protocol enhances smart contract functionalities by granting them access to reliable data without any central points of failure. Decentralized Finance applications need price feeds on token swap and loan collateralization process. With Band Protocol’s built-in price oracle, developers can build DeFi with an absolute peace of mind that the price feeds they’re using are robust and tamper-proof. BandChain is designed to be compatible with all smart contract platforms and blockchain development frameworks. In a trustless and decentralized manner, BandChain does all the heavy lifting jobs of pulling data from external sources, aggregating, and packaging them. -

OKT Chain (OKTC)
OKX
The world's first trading chain, a decentralized, borderless, blockchain-based ecosystem for exchanging value. OKT Chain (OKTC) is a public permissionless blockchain that no one fully controls. Anyone can create projects and use applications from anywhere in the world. OKX can neither control nor endorse any projects on OKT Chain (OKTC). The decentralized nature of blockchain may lead to risks. Make sure you're responsible for your financial decisions and do proper research on projects. Research and understand a project before interacting with OKT Chain (OKTC) in any way. Remember that all developers and users can access both main and test networks for free. Distinguish between OKC main and test networks. All assets on the testnet are valueless. Protect your private keys and never share them. Make sure third-party projects are safe before authorizing them. We support MetaX, MetaMask, imToken, TokenPocket and other wallets. -

Oasis Network
Oasis Protocol Foundation
The Oasis Network is a privacy-enabled blockchain platform for open finance and a responsible data economy. By bringing privacy and scalability to DeFi, the Oasis Network expands DeFi beyond early adopters to a mass market. It enables private smart contracts, high scalability, and the ability to tokenize data. This unlocks new use cases like private lending, undercollateralized loans, and private automated market makers. The Oasis Network’s unique combination of confidential computing and blockchain enables a new paradigm called Tokenized Data. With Tokenized Data users can earn rewards by staking their data with apps that want to analyze it or control how their most sensitive information is consumed by the services they use. The Oasis ParaTime scaling architecture supports fast transaction speed, high scalability, and large workloads by separating execution from consensus. ROSE is the native, capped supply utility and settlement token for the Oasis Network. -

Kusama
Kusama
Unprecedented interoperability and scalability for blockchain developers who want to quickly push the limits of what’s possible. Built using Substrate with nearly the same codebase and industry-leading multichain infrastructure as Kusama’s cousin, Polkadot. The relationship between society and technology has deteriorated to the point where large entities routinely stretch and overstep their authority. Kusama is a network built as a risk-taking, fast-moving ‘canary in the coal mine’ for its cousin Polkadot. It's a living platform built for change agents to take back control, spark innovation and disrupt the status quo. Move fast and ship your product. Kusama’s risk-taking and nimble mentality allows developers to move swiftly through the governance and upgrade process, enabling rapid progress and growth. Build on a next-generation, sharded, multichain network, while employing the newest features before they are deployed on Polkadot.
