Tomochain is an innovative solution to the scalability problem with the Ethereum blockchain. Tomochain plans to support horizontal scaling via adding more second layer blockchains with good performance integrated with Ethereum for backup and atomic cross-chain transfer. Tomochain is envisioned to be a network of chains that supports instant confirmation, and near zero transaction fee which will be an ideal solution for decentralized apps, token issuances and token integrations for small and big businesses.
Launched on Dec 25, 2016, Obyte is a distributed ledger based on directed acyclic graph (DAG). Thanks to absence of blocks and miners, access to Obyte ledger is decentralized, disintermediated, free (as in freedom), equal, and open. Obyte is the first DAG based cryptocurrency platform to support dApps. Due to absence of miners and blocks, there is no risk of front-running and other miner manipulation, and dApps are safer and easier to develop than blockchain based dApps. DApps are developed in Oscript - a new language that avoids many unsafe programming patterns common in earlier dApp platforms. Thanks to its safety, Obyte is especially well suited for DeFi apps, some are already available on the platform, such as Discount Stablecoins (https://ostable.org), some are being developed. Other features include: self-sovereign identity, private untraceable currencies, sending crypto to email using textcoins, and extremely small-footprint libraries suitable for small IoT devices.
