  • EB52 – Paul Snow & Peter Kirby: Factom, Proof of Existence, Proof of Process, Proof of Audit

    Today's episode is all about Factom, an open source project which aims to solve three core problems which apply to all Bitcoin 2.0 applications: Speed, Cost, and Bloat. Rather than writing every transaction to the blockchain, Factom allows decentralized applications to write blocks of transactions to Factom blocks, which themselves get hashed and stored to the bitcoin blockchain. At its core, Factom provides Proof of Existence, which allows for any digital artifact to be reduced to a hash that proves that artifact's existence at a specific point in time.
    We are joined by Factom CEO, Paul Snow, and President, Peter Kirby, to explore the different applications of Factom as well as the technical workings of this very interesting and promissing project.

We talked to David about the recent whitepaper he co-wrote titled “The General Theory of Decentralized Applications, DApps” which defines the different types of DApps and a number of best practices with regards to funding, token distribution, business models, etc. We also discussed the DApps Fund, BitAngels Network and the Master Protocol, and his involvement with those projects.

      • Meni Rosenfeld: Mining Pool Reward Systems, Bitcoin Economics, Bitcoin in Israel

        Meni Rosenfeld is Founder of Bitcoil and Chairman of the Israeli Bitcoin Association. Having organized several meetups and conferences in Israel, he is a very active member of the Israeli Bitcoin community. Meni has been studying mining pool reward methods for several years and in 2011, wrote a paper titled “Analysis of Bitcoin Pooled Mining Reward Systems”. This research gave him a broad understanding the reward system landscape and the issues with many of the methods used by pools. He later wrote proposals for alternative non pay-per-share methods and which would render pool hopping impossible: the geometric method and double geometric method.
