Here are some simple animations showing some design features of RaiBlocks.

Block lattice visualization

RaiBlocks has one block chain for each account which is controlled by the account's private key and each block chain is replicated to all peers in the network, we call this arrangement a block lattice.

Balances are transferred between block chains through send and receive blocks. Send blocks reduce the balance of an account and marks the delta as receivable by an account number. At a later time the receiving account creates a receive block which increases the balance of their account by the delta.

Ledger pruning (in development)

Since each account operates on its own block chain, lite peers are able to do much more selective and aggressive pruning of the block chains. Only bootstrap or peers interested in doing full ledger validation actually need to store the full ledger history.
