Each NFTs represents a DecBC Genesis Block Account. The DecBC blockchain consensus is based on Proof of Participation, and accounts registered in the genesis block are allowed to run a node of the peer-to-peer network. DecBC Genesis Block Accounts are sold as NFTs, and owners can trade and sell them until 30 November 2022, and personalize them until 20 December 2022. After that date the NFTs will be frozen, and it will be always possible to match the blockchain genesis block with the minted NFTs. This guarantees that the genesis block has not been tampered with.
