- krupan 3y agoThe transactions are part of what is hashed, so they have to be chosen before the miner starts trying to win the block
- scotty79 3y agoThey choose transactions to include before they attempt mine a block. Then after they successfully mine a block (which is rare) those transactions become a part of the ledger. Usually they take the transcations from public mempool that contains transactions waiting to be confirmed. But in theory miners could include the transactions that were never put in the mempool. Although they would need to have a significant portion of global hashrate to mine such blocks at any sensible rate, not just very occasionally.
