Keep3rV1 Keep3rV1 is an Ethereum-based platform that utilizes KP3R, an ERC-20 governance token. This means that it relies on the Ethereum blockchain to validate any on-chain KP3R transactions. Ethereum uses a proof-of-work consensus algorithm in which miners compete among each other to add new blocks to the blockchain and a majority of all nodes in the network must confirm a record for it to be posted.
