GUEST Jonas Nick

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
