Epicenter - Learn about Crypto, Blockchain, Ethereum, Bitcoin and Distributed Technologies

In the early days of Bitcoin, much of the community’s focus was around payment and getting merchants to adopt cryptocurrencies. Although the technology and narratives have evolved, some projects continue to embrace that original vision of peer-to-peer business, where merchants and their customers interact directly, and if they so wish, anonymously. We’re joined by Brian Hoffman and Washington Sanc...

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...

Artificial Intelligence is often misunderstood. And much like blockchain, those who fiercely stand by the technology believe it will change the world for the better. Others fear the negative repercussions it could bring it and would rather see it disappear. We’re joined by Ben Goertzel. Ben’s interest in AI and robotics date back to his childhood and he has made these his life-long passion and wor...

We’re joined by Alexey Akhunov, an independent Ethereum researcher. Alexey has been working on an ambitious project called TurboGeth. As the name implies, it is a version of Geth which features a number of speed and performance optimizations. Alexey also leads the state rent working group of the Ethereum 1.x project. Ethereum 1.x came out of Devcon when core developers began to realize that the fu...

When the Lightning Network (LN) was conceived in 2015, it was quickly embraced by the Bitcoin community as the way to dramatically scale Bitcoin’s capacity. There was an expectation of LN being available quickly. Instead, development proceed more slowly in the background with different teams contributing to a standard specification. That spec is now almost ready and last year interest and early ac...

We’re joined by Jameson Lopp. Jameson is the CTO of Casa, a company providing key storage solutions. Previously, he was an early engineer at BitGo. However, to most people, he is perhaps known for his Twitter presence and his excellent writing. Over the years, Jameson has written extensively about Bitcoin development, cryptocurrencies, and personal operational security. A self-proclaimed “Professi...

The concept of DAOs has been captivating to many in the crypto space for years. When “The DAO” was created in 2016, in the few weeks of its existence and despite obvious flaws, it gather tremendous momentum and amassed 14% of the entire ether supply. Since then the technology has matured and Martin and Matan argue that the time for DAOs has finally arrived. We were joined by DAOstack Founder Matan...

Epicenter turned 5 years old this month – that’s a long time in the blockchain space! When the podcast began in January 2014, the entire ecosystem was made up of only Bitcoin and a handful of altcoins. Soon after, the Ethereum white paper was published which ushered in a new era of crypto assets and decentralized applications. Since then, we have released 270 episodes and interviewed some of the l...

We’re joined by Joseph Lubin, Founder and CEO of ConsenSys. Joseph founded ConsenSys as an Ethereum development studio on the heels of the Ethereum crowd sale in 2014. The company has since grown to a distributed organization of over 1,000 people. Over 50 companies and projects have emerged from ConsenSys, including Metamask, uPort, Gnosis, and GitCoin, to name only a few. Today, the company conti...

When token sales and ICOs took off in 2017, most projects chose to push ahead despite large regulatory risks. One of the few that went the other direction and put compliance first was CoinList. The platform made its debut by running the massive Filecoin token sales in which $205m was raised from accredited investors. CoinList also played a major role in popularizing the SAFT and creating tools to...

Lending is one core pillar of the economy, enabling one person or company to be entrepreneurial with someone else’s capital. However, in the traditional banking system processes in lending are often opaque and the barrier to entry into this market is high. The emergence of easy to use Decentralized Finance is one of the hallmarks of 2018: To date, DeFi has brought us crypto-collateralized stable c...

Since the rise of digital currencies and cryptocurrencies, central banks are considering the role these new forms of money may play in our evolving digital economy. One of the ideas studied is the notion of a central bank digital currency. While people and companies can hold central bank liabilities in the form of cash, only licensed banks have access to digital cash accounts with central banks. W...

While trustless interactions on Ethereum are native to the protocol, trustless interactions between the Ethereum blockchain and other blockchains are difficult to implement. Interoperability protocols heavily rely on atomic swaps, which typically come with a free option problem. For this episode we’re joined by James Prestwich, CEO at Summa. Summa designs and implements cross-chain financial contr...

We enter dozens of trust relationships ever time we interact with the Web. Browsers, ISPs, DNS providers, cloud hosting companies, all the way down to the handful of people who control certificate root keys; we rely on the integrity of these intermediaries to serve reliable, and accurate information. The concentration of power by any one of these actors threatens to compromise the very foundationa...

The Ethereum vision has always been to create a world computer. But its scalability and performance limitations have meant that it has fallen far short of that vision. Yet, work on scaling Ethereum has exploded in breadth and complexity over the past years. From variants of PoS, to Plasma / Plasma Cash, sharding, EWASM, BLS signatures, everything has been on the table. While confusing on the surfa...

Most observers of the ecosystem will probably agree that 2015-2017 were the years of the enterprise blockchain. It was during that time that many startups catering to enterprise were founded and funded, including Monax and Stratumn (where Brian and Sebastien previously worked). For the permissioned blockchain camp, adoption would come in the form of enterprise use cases, arguing that public networ...

The difficulties of compensating content creators for their work has been a driving force of the web for decades. It gave rise to advertising-driven tech giants like Google and Facebook and contributed to the decline of industries like music and publishing. Coil aims to change this and leverage blockchain and the Interledger Protocol to build a new business model for the web. We were joined by Coi...

It’s that time of year again, Devcon time! Just as the conference was wrapping up, we sat down at the Prague Congress Center for a Devcon4 recap.

Their Chainweb protocol will soon launch as a public network and smart contract platform. The company claims their novel approach to proof...

Building open source software is a collaborative process which relies on good faith and willingness of volunteers. While most of the software we use daily relies heavily on open-source libraries, incentive models are broken. Repo maintainers are eager to see their projects evolve, but have little leverage to encourage developers to contribue. And projects contributors create enormous value by dedi...

CoinFund is one of the earliest crypto-funds to have taken shape, forming in early 2016. The fund is well known for running an active Community Slack, conducting great podcast interviews with cryptocurrency projects and an emphasis on building network nodes / services. We are joined by Jake Brukhman, CEO, and Alexander Bulkin, Chief Alchemist, to discuss their latest thoughts on investing in the c...

The Tezos whitepaper, published in 2014, anticipated several areas that would become major issues for blockchain networks. Especially around governance and smart contract security, Tezos proposed original solutions. The project later went on to raise $232m in the biggest token sale at the time. Recently, the Tezos network launched as the first of a wave of innovative next-generation blockchain net...
