Description

Harmony is a fast and open blockchain. Our mainnet runs Ethereum applications at a speed of two seconds and with 100 times lower fees. Harmony's secure bridges allow cross-chain asset transfers between Ethereum, Binance, and other chains. Harmony is a platform that allows creators to connect with the community. Harmony's bridges are able to connect any Proof of Work and Proof of Stake chains. FlyClient architecture is completely trustless and extremely gas-efficient. Our bridges for Ethereum or Binance Smart Chain currently secure tens to millions of cross-chain assets. Developers can simply change the Chain ID to enjoy faster executions of EVMs identical at bytecode level. They can easily migrate to Harmony using their familiar Web3 tooling. What about users? Users can use MetaMask and Ledger as usual, but they will now only have to pay minimal fees. Any Ethereum portal or wallet can work on Harmony without any code modifications or new installs.

Description

Create Decentralized Proof Of Timestamp: Ethereum-based certifications of digital content that existed before a certain time. TProof has been designed to support any amount certification. It's primarily based upon two major platforms: Ethereum (or Arweave). Ethereum is where the certification takes place. It stores the hash of your file at a particular timestamp. This combination is represented by an NFT, which you can freely move and trade with. Arweave allows you to upload your file and make it public (and permanent). This optional step is for those cases where you want the file to be visible everywhere in the world, not just the hash. Our Smart Contract can be integrated by any company or Web3 project that requires a cryptographic proof to support digital content.
