Byteball is a decentralized database with it’s own native cryptocurrency, Bytes, that unlike most does not require PoW or PoS mining and does not have a blockchain nor blocks. Instead, Byteball links transactions by signing the hashes from the previous transactions on the new one. These links between transactions form a DAG (Directed Acyclic Graph). Since Byteball has no blocks, there is no block size issue.
Byteball enables trust where trust couldn’t exist before.
When a contract is created on Byteball platform, it can be trusted to work exactly as agreed upon. Why? Because it is validated by multiple nodes on the decentralized network, which all follow the same immutable rules. The counterparty, even if it is a total stranger, has to behave honestly because only the rules have authority. Such a contract is called a smart contract. See below for examples of working smart contracts available today.
