When a block is transmitted, each node that receives it can decide to append this block onto its most extended chain. (This is the default behavior in bitcoin, which guarantees that we can achieve consensus.) Then the node can start mining a new block linking to this latest addition as its previous block. We can say that a transaction is accepted when a specific number of nodes have added this block onto their freelance blockchain developer chains. As blockchain technology continues to disrupt, blockchain-related jobs are flooding the market.
