Why Altcoins are Technically Flawed with Nadav Kohen

“You don’t want to use the blockchain unless there’s actually some kind of dispute; all cooperative transactions in the world can exist off of the blockchain and there’s no reason to actually use a blockchain for them”— Nadav KohenLocation: RemotelyDate: Friday 25th JuneCompany: SuredbitsRole: Software EngineerBitcoin's proof-of-work blockchain solves a specific problem: achieving consensus of a distributed ledger without a central authority. Out of this decentralised network, new properties emerge like censorship resistance and probabilistic finality.Bitcoin's success led to an explosion of altcoins, with most claiming to improve upon Bitcoin somehow, whether it's speed, privacy or scalability. However, blockchains are a delicate balance of specific tradeoffs, and these altcoins pale in comparison to Bitcoin's decentralisation and censorship resistance. While changing a parameter might seem to add functionality, it can also introduce unintended consequences. To resist influence and attacks, Bitcoin must remain decentralised by allowing for easy validation.Can we achieve sufficient privacy and functionality on the second layer? And why are other consensus methods, like proof-of-stake, flawed?In this interview, I talk to Suredbits software engineer Nadav Kohen. We discuss why blockchains must scale with second layers, proof-of-stake vs proof of work, and tradeoffs of privacy technology.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 walletRevolut - A better way to handle your money-----WBD369 - 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.
