    TokenScript

    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

    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.

    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.
