Bitcoin Tech #4 - Wrapped Bitcoin & Sidechains with Shinobi & Nadav Kohen

“Blockchains solve a very specific problem, that’s their big innovation, but they suck at pretty much everything else.”— Nadav KohenLocation: RemotelyDate: Tuesday 27th AprilCompany: Block Digest, SuredbitsRole: Host, Software EngineerSince Bitcoin’s inception, scaling has been a divisive topic. The very first reply to Satoshi Nakamoto’s email introducing the bitcoin whitepaper stated that “We very, very much need such a system, but the way I understand your proposal, it does not seem to scale to the required size.”The scaling debate came to a head in the block size wars. Part of the community wanted to scale bitcoin by increasing the block size. However, a larger section believed that scaling was better handled on other layers, culminating in 2017 with the BCash fork.Four years on and the market has decided that layered scaling is the preferred solution. Today, there are several approaches to off-chain settlement, and by experimenting with these on higher layers separate from the protocol, the security of Bitcoin can remain robust.These different second layers offer additional functionality and programmability not found on the Bitcoin base chain, but they do come with tradeoffs. Users should consider who or what they are trusting, be it a peg, a federation, a protocol, or a combination.In this interview, I talk to Shinobi, the host of Block Digest and Suredbits software engineer Nadav Kohen. We discuss Bitcoin scaling, the Lightning Network, wrapped Bitcoin and Liquid.This episode’s sponsors:Gemini - Buy Bitcoin instantlyBlockFi - The future of Bitcoin financial servicesSportsbet.io - Online sportsbook & casino that accepts BitcoinCasa - The leading provider of Bitcoin multisig key security.Exodus - The world's leading Desktop, Mobile and Hardware crypto wallets.Ledger - State of the art Bitcoin hardware wallet-----WBD342 - Show Notes-----If you enjoy The What Bitcoin Did Podcast you can help support the show by doing the following:Become a Patron and get access to shows early or help contributeMake a tip:Bitcoin: 3FiC6w7eb3dkcaNHMAnj39ANTAkv8Ufi2SQR Codes: BitcoinIf you do send a tip then please email me so that I can say thank youSubscribe on iTunes | Spotify | Stitcher | SoundCloud | YouTube | Deezer | TuneIn | RSS FeedLeave a review on iTunesShare the show and episodes with your friends and familySubscribe to the newsletter on my websiteFollow me on Twitter Personal | Twitter Podcast | Instagram | Medium | YouTubeIf you are interested in sponsoring the show, you can read more about that here or please feel free to drop me an email to discuss options.
