Wakacoin Blockchain

The block chain provides a public ledger of Wakacoin, an ordered and timestamped record of transactions. This system is used to protect against double spending and modification of previous transaction records.

Each node in the Wakacoin network independently stores a block chain containing only blocks validated by that node. When several nodes all have the same blocks in their block chain, they are considered to be in consensus. The validation rules these nodes follow to maintain consensus are called consensus rules.
