nonce

The #blockchain is maintained by a #PeerstoPeers network of nodes. Nodes validate and broadcast transactions, each storing a copy of the blockchain for ownership verification.
do not act as nodes but they communicate with nodes as miners also group and broadcast new transactions into blocks to be validated by nodes.
In order to be accepted by nodes, each block must have a proof of work - involving finding a #nonce number.
The proof of work is simple to verify but hard to generate.
#proofofwork is the foundation of $BTC decentralized consensus mechanism, i.e. agreeing on which transactions to commit to be valid without a central authority.
