But, I don’t think anyone’s sent a “poison_microblock” transaction yet, because no one has produced a forked microblock stream. If you look on the block explorer ( ), you can filter the chain’s transaction history by “smart_contract” or “contract_call” transactions – there’s lots of them. But i could not find a block where other 3 transaction types are there. For “coinbase” and “token_transfer”, i found that if these transactions types are there - we need to look for “coinbase_payload” & “token_transfer” : amount. I found in documentation that there are 5 transaction types:“coinbase” “token_transfer” “smart_contract” “contract_call” “poison_microblock”. This isn’t used right now, but it’s meant for storing in-band signaling like votes for activating new features via soft-forks. The coinbase wire format gives miners 32 bytes of “scratch area” to store whatever information they’d like. In most coinbase transactions, we can see “coinbase_payload” as 0. This address “sent” coinbase transactions because it has mined blocks – those coinbase transactions are the coinbases from the blocks it mined. The query above returns all of the transactions sent from SP3MK…VHS4V. Can you explain the significance of these? Generally in Bitcoin blockchain, there is only one (first) transaction which is marked as coinbase transactions but in the above block i can see more than 150 transactions which are marked as “Coinbase”. But i could not find a block where other 3 transaction types are there.Ĭan you please help me understand the meaning of these transactions and also what are the keys i should look for when these transactions occur. I found in documentation that there are 5 transaction types:“coinbase” “token_transfer” “smart_contract” “contract_call” “poison_microblock”.In most coinbase transactions, we can see “coinbase_payload” as 0.For certain types of transactions, also linked resources with type value as field will be included in the payload (example buy and sell). If theres another party, the transaction will have either to or from field. It can be either negative or positive on amount depending if it credited or debited funds on the account. Can you explain the significance of these? Transaction resource represents an event on the account. Generally in Bitcoin blockchain, there is only one (first) transaction which is marked as coinbase transactions but in the above block i can see more than 150 transactions which are marked as “Coinbase”.Hi was checking the transactions array using below API:Īnd was having some questions which i could not get clear answers in the documentation:
