Proof-of-Contribution consensus mechanism for blockchain and its application in intellectual property protection

作者：

Highlights：

• A new consensus mechanism Proof-of-contribution was proposed for public blockchain.

• User behaviors were quantified as blockchain contribution values through an algorithm.

• The highest contribution node gets the right of bookkeeping in each consensus round.

• PoC exhibited many advanced properties than PoW and is applicable for public blockchains.

• The design of an intellectual property protection blockchain applied PoC was described.
