Package relay is a proposed feature for Bitcoin relay nodes that would allow them to send and receive packages of related transactions which would be accepted or rejected based on the feerate of the overall package rather than having each individual transaction in the package accepted or rejected based only on its own feerate.| Bitcoin Optech
Transaction pinning is a method for making fee bumping prohibitively expensive by abusing node protections against attacks that can waste bandwidth, CPU, and memory. This can make fee management more difficult in multiparty contract protocols (such as LN).| Bitcoin Optech
Anchor outputs are special outputs in LN commitment transactions that are designed to allow the transaction to be fee bumped. An earlier name for the proposal was simplified commitments.| Bitcoin Optech
Child Pays For Parent (CPFP) is a fee bumping technique where a user spends an output from a low-feerate unconfirmed transaction in a child transaction with a high feerate in order to encourage miners to include both transactions in a block.| Bitcoin Optech
