Byteball enables safe contracts that can be trusted to execute exactly as agreed upon. And it works in circumstances where other methods don’t work. And even when they do work, Byteball makes enforcement orders of magnitude cheaper, faster, and more certain.
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.
