Zeppelin Co-Founder and CTO Manuel Araoz joined us to discuss his journey from building one of the first non-financial Bitcoin applications in 2012 to improving development and security practices for Ethereum smart contracts. We discussed the OpenZeppelin framework, a library of audited smart contracts as well as their new project zeppelin_os. Through on-chain, well-vetted and upgradeable smart contracts zeppelin_os aims to make developing Ethereum applications both easier and more secure.Topics discussed in this episode:Manuel's journey in the blockchain space from proof of existence to BitPay to Streamium to ZeppelinWhy Manuel moved away from a pure Bitcoin focus to working on EthereumWhy Zeppelin focuses on smart contract securityHow smart contract security evolved since the start of EthereumThe OpenZeppelin framework of audited Ethereum contractsWhy zeppelin_os and standardized, upgradeable on-chain contracts are the next evolutionary stepThe core component of zeppelin_os: Kernel, SDK and markeplaceThe ZEP token and its role in zeppelin_osLinks mentioned in this episode: Zeppelin WebsiteOpenZeppelin Frameworkzeppelin_oszeppelin_os WhitepaperSupport 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.tvYouTubeSouncloudWatch or listen, Epicenter is available wherever you get your podcasts.Epicenter is hosted by Brian Fabian Crain, S?ƒbastien Couture & Meher Roy.
