Three years ago, a mysterious txt file signed by a pseudonymous Tom Elvis Jedusor was dropped in the Bitcoin-Wizards IRC channel outlining a proposal called Mimblewimble. It proposed a novel way of combining many ideas from Bitcoin research in order to create a new blockchain protocol that will be highly scalable and increase privacy, while still using the same cryptographic assumptions as Bitcoin. A few months later this project was picked up by another pseudonymous individual who started working on an implementation he called Grin. Grin slowly began to draw attention from the Bitcoin community and got a lot of traction. We join Michael Cordner (Yeastplume) and Daniel Lehnberg, two of the core developers of the Grin blockchain. In this episode we discuss some topics around Grin's cypherpunk origins, privacy and scalability features, no-premine fair start, and interesting monetary policy. Topics discussed in this episode:Origins of the Mimblewimble proposal and the prior work it draws uponAndrew Poelstra's contributions to improving and fixing the original proposalScalability and fast sync times achieved through mimblewimble's UTXO set compressionHow UTXO compression when combined with the Dandellion p2p protocol can increase privacyChanges in user experience from Bitcoin to MimblewimbleBeginning of the Grin project as an implementation of the Mimblewimble protocolComparision to BEAM, a competing Mimblewimble implementationInnovating on fair Proof of Work through dual Cuckoo CycleGrin's Monetary Policy and the Mining Fair Start Links mentioned in this episode: MimbleWimble OriginAndrew Poelstra's Improved PaperIntroduction to GrinGrin for BitcoinersGrin NewsletterMichael Cordner on TwitterDaniel Lehnberg on Twitter Sponsors: Azure: Deploy enterprise-ready consortium blockchain networks that scale in just a few clicks Support the show, consider donating: BTC: 1CD83r9EzFinDNWwmRW4ssgCbhsM5bxXwg (https://epicenter.tv/tipbtc)BCC: 1M4dvWxjL5N9WniNtatKtxW7RcGV73TQTd (http://epicenter.tv/tipbch)ETH: 0x8cdb49ca5103Ce06717C4daBBFD4857183f50935 (https://epicenter.tv/tipeth) This episode is also available on :Epicenter.tvYouTubeSoundcloud Watch or listen, Epicenter is available wherever podcasts are distributed.
