58:37 Share

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
