[Bug] Transaction hash changed to another after some time

What happened?

2022-06-22 about 17:30 i sent some Chia to address: xch1uk9a4fdyhacrg9y8kqqan3rw4fwefzszyjpzruj7tmuhm32h0ksq59xwkz

Then the transaction hash was as follows: 0x22240f1ce00cef8d2f8c89e85f79c2d9657108772485fb2f9f55ce31e86a8dbc Now after a few days Chia wallet shows different hash for the same transaction: 0x9a968ba9f2a0f552e4c0d845fae4f682d1f845930a3bd016b8ac0b8b21a610c4

The transaction is still visible in the block explorer under the old hash, and there is no information about the new one. So why has the hash changed over time? How can we uniquely identify a given transaction if the transaction hash is not reliable?

Did you resync the wallet DB in the meantime?

Chia doesn’t have transactions per se - it has coins. For record-keeping, the notion of a transaction is solely a local wallet construct and represents the hash of the entire spendbundle submitted to the chain. The chain itself (and the various explorers) do not allow viewing this spendbundle hash as a transaction. You cannot view this transaction on chain, you can only view coins

However, if you do chia wallet send... that transaction id (and spendbundle) is stored in the wallet DB and shouldn’t change - however, this spendbundle as submitted to the chain is ONLY stored in the wallet db . It should remain there and allow you to query it based on the ID, as long as you do not resync the wallet. Once you resync the wallet however, you lose all the information about these spendbundles and the transaction id will no longer be available.
