ckb 0.112.1 (4b1bcd7 2023-11-21)

Highlights

Here are the highlights of the version v0.112.0:

• Introduce the new method generate_epochs in the IntegrationTest module (#4128)
• Add feature of Replace-by-fee for tx-pool (#4079, #4108, #4232)

We introduce a huge code refactor on the transaction pool module and added the feature of RBF(Replace by Fee) in this release.

Here are two points need to be noted:

1. Double-spending check now will work before any transaction is added to the transaction pool, a transaction that conflicts with current transactions in the pool will be rejected, the only way to add the new transaction into the pool is by improving the fee and if RBF checking passed, transaction pool will remove old conflicted transactions, then add the new one into pool.
2. The RBF feature enables users to replace a transaction with a higher fee rate when pending in tx-pool, which is useful when the transaction is stuck in the tx-pool.

More details about RBF:
The most important rule is fee, you need to pay an extra fee to replace old transactions with the new one. The default min_rbf_rate in ckb.toml is 1500, which means the minimum extra fee rate for RBF, the unit is shannons/KB.

min_replace_fee = sum(replaced_tx_fee) + (min_rbf_rate * size)

The replaced transaction will be removed from tx-pool and with the status Rejected. The RBF may replace a transaction in the status of Pending or Proposed, but the old transaction may still be committed if it was in Proposed.
