DIVA.EXCHANGE in a nutshell: the Iroha Blockchain

Any kind of blockchain is just a simple distributed and redundant data storage. No matter how much complexity is imposed on the data memory (e.g. when programs, “smart contracts”, are stored on the blockchain) – it remains data memory. The sensible thing about a blockchain is its distributed data storage and – only with sufficient distribution – the integrity of the data over time (“fallibility”). Everything else is just smoke and mirrors.
