Jonas Nick & Tim Ruffing, bitcoin researchers and contributors at Blockstream rejoin me on the show, this time to chat about half signature aggregation. This is a scaling technique that can help scale Bitcoin and enable more transactions inside a block or help with L2 protocols. We discuss:
- How this idea came to be
- What is half aggregation vs ‘full aggregation’?
- What kind of savings are possible?
- What are the downsides?
- How would this work in practice?
- Is a soft fork required?
- Next steps for discussion, research, contributors
