BlockStamp (BST) is a new digital currency intended to store user data in blockchain. It is based on Bitcoin peer-to-peer technology to operate with no central authority. To distinguish from Bitcoin, BlockStamp uses hashes of blocks beginning with the most significant bit set to one (0x80000000.... instead of 0x00000000...).
The blockchain will be used to offer cheap transactions for time-stamping of documents. The BST-client will enable the submission of the hash of a document or the whole document in a transaction to be recorded on the blockchain.
