Abstract. One of the descendants of Bitcoin, Fluttercoin sets itself apart as the first
crypto-currency to provide transactions as a proof of participation. Proof-oftransaction
adds an additional layer of blockchain and transactional security by allowing
economic participants to prove they were involved in a transaction. This system verifies
the coinbase of every proof-of-work block, and validity of a proof-of-transaction reward
or lack thereof. The result, secures the blockchain as all unmodified nodes will reject
invalid blocks that should or shouldn’t have included a proof-of-transaction rewards.
