Improving the money of the future A discussion on ways to improve instant transactions

A collaborative and highly-technical three-day workshop with the goal of improving instant transactions for Bitcoin Cash. Attendance was limited to active developers, researchers, and key stakeholders.

The workshop's main focus was to develop strategies for improving instant transactions that can be implemented over the short term (addressing the fast-respend and reverse-respend vulnerabilities). Examples include double-spend relay, super-standard transactions, and double-spend proofs. A secondary focus was on longer-term ideas, such as those based on pre-consensus techniques, to address the double-spend vulnerabilities that involve miner collusion.

The workshop included round-table discussions, working groups, and technical presentations.
