In this talk, Andreas speaks about permissionless innovation in Bitcoin's network architecture, and the economics of open systems that enable a festival of the commons. This talk was delivered on January 27th 2015, at the O'Reilly Radar Summit "Bitcoin and the Blockchain" in San Francisco, CA: https://conferences.oreilly.com/bitcoin-blockchain-2015 Video is licensed CC-BY CORRECTION: At 13:12, I said that multi-signature transactions were added to Bitcoin and the first multi-sig wallet deployed in 2014. This is not true. The BIPs for multi-sig were finalized in 2011 and 2012. Multi-sig was being used prior to 2014, but only a very small percentage of bitcoin was held in multi-sig addresses, and no consumer-facing multi-sig wallets were available. BitGo deployed a multi-sig wallet in August 2013.

Blockchain technology presents opportunities for dissonant opinions, fractionalization and internal reform unmatched in the fiat world. Join hosts Jonathan Mohan, Stephanie Murphy and Andreas M. Antonopoulos as they dissect “Voice and Exit,” or the power and necessity of being able to impact a system, whether financial, social or governmental, and if necessary, leave altogether. “Voice and Exit” was popularized by Balaji Srinivasan in 2013, where Srinivasan outlined how voice is attempting to change a system from within, while exit is leaving to create a new one. Crypto has provided new methods to exercise voice and exit. Forks, software or protocol changes that users can choose to upgrade to, are an example of exit inherent to blockchain technology. Forks give the community a chance to decide whether to continue with the upgrade or remain in the old rules; forks have created spin-off currencies like Bitcoin Cash and Bitcoin SV. As opportunities for voice and exit seem to be gradually disappearing, can crypto help those who need them most?

Irreversible transactions and consumer protection. Why would people want irreversible transactions? Will that slow down adoption? The difference between a system of hard promises which can be softened and a system of soft promises which can't be hardened. We're used to operating in a system of soft promises, where your bank can reverse your transactions whether you ask it to or not. These blockchain system involve hard promises, but Bitcoin and Ethereum do not guarantee that a payment will happen irreversibly -- it guarantees that the contract within the transaction will be executed irreversibly. If that contract says "Without second thought, send this money to here and never look back," that is the contract which is going to be executed irreversibly. But that's not the only contract you can put in there. Options: 30-day refund payments, third-party escrows, reintroducing counter-party risk. The difference is that the owner of the money is the only one who can reintroduce those constraints. It is an irreversible guarantee that the wishes you expressed as a consumer within your transaction script will get executed, simulating all of the softness that you want. Right now it's too difficult to do those scripts, but that's an engineering problem just a few rounds of incremental innovation away. We can offer more robust, more predictable guarantees for consumer protection than any system of soft promises. There will be bugs, but you iterate through the bugs.

In this short video excerpt from aantonop's January 2024 Q&A session, Andreas explains that there's no one magic tool to make you 100% secure. Instead security is a matter of probabilities, balancing people, process, and tools. If you'd like to learn more about self custody, check out aantonop's Path to Self Custody Workshop Bundle, with a 14 day money back guarantee. You'll learn about people, process, and tools and get a hands-on demonstration of how to initialize, backup, test, and restore a hardware wallet. https://aantonop.com/workshop COMMENT below and let us know what you think of the video.
