What is the replace-by-fee (RBF) policy?
The RBF policy was introduced in the Bitcoin protocol to provide flexibility to users who want to speed up their transactions or modify the fee in response to network constraints.
High transaction fee selection
Users may intentionally choose a high transaction fee for quicker confirmation or due to a fee miscalculation.
RBF policy
Under the replace-by-fee policy, users can replace an unconfirmed transaction with a higher-fee transaction to ensure faster confirmation.
Sender’s unawareness
The sender may not have been fully aware of the network conditions or the consequences of their actions, leading to a significant increase in transaction fees.
Which blockchain networks support RBF?
RBF is supported by Bitcoin Core, the reference implementation of the Bitcoin protocol. However, not all wallets and services within the Bitcoin ecosystem may adopt or offer this feature. Users should confirm the compatibility of their wallet or service with the replace-by-fee policy.
How does the replace-by-fee policy work?
The effectiveness of RBF depends on the state of the network, miners’ rules, and support from participating nodes and wallets. The process involves initiating a transaction, adjusting fees, including a replace-by-fee flag in a new transaction, broadcasting it for miners’ consideration, and confirming the replacement transaction if included in a block.
How to enable and disable RBF?
To enable RBF, users must ensure their selected wallet supports this feature and enable it in the wallet settings. Disabling RBF can also be done through wallet settings. Specific instructions may vary depending on the wallet being used.
Disadvantages of replace-by-fee policy
RBF raises concerns about double-spending and can complicate the user experience. It also impacts transaction reliability and predictability, as well as the overall efficiency of the network. Misuse of RBF can lead to fraud and financial exploitation, highlighting the need for careful use and user education.

It allows for faster confirmation and gives users control over their transactions. However, RBF also comes with disadvantages. It raises concerns about double-spending and can complicate the user experience. It may impact transaction reliability, predictability, and network efficiency.
