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 surface, underneath a coherent vision for a new Ethereum that will scale near infinitely has emerged. We ...

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 networks carried too much risk, and lacked needed features like privacy. While much of the hype has subsid...

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 Coil Founder and former Ripple CTO Stefan Thomas and Coil Co-Founder Ben Sharifian to discuss their amb...

We’re joined by Monica Quaintance, Head of Engineering and Adoption at Kadena. While most companies providing enterprise solutions focus primarily on permissioned systems, Kadena is building both a public network protocol and private blockchain infrastructure. Their Chainweb protocol will soon launch as a public network and smart contract platform. The company claims their novel approach to proof of work offers enormous gains on transaction throughput, even at scale, while benefiting from the sa...

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 dedicating their time and expertise while getting little in return. Both open and closed-source projects...

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 networks. We were joined by Tezos co-founders Arthur and Kathleen Breitman to discuss the history of th...

Public blockchains produce enormous amounts of data. In theory, anyone can access the raw contents of transaction and blocks. In practice, however, querying blockchains can prove to be a daunting task. The difficulty lies in the fact that blockchains are particular types of distributed databases and thus carry several limitations. Most, if not all, blockchains lack the most basic SQL querying capabilities supported by nearly every off-the-shelf database system. Take Bitcoin as an example. Its AP...

The expectation has become widespread that blockchains will end up underpinning major societal infrastructures. The narrative in the blockchain space is that networks are decentralized and trustless and thus regulation should not apply to networks directly. Legal scholar Angela C. Walch has been questioning terms like decentralization and trustlessness and argues that blockchains shift the need for trust rather than remove it. Her controversial ideas include that key developers of open-source pr...

Dispute resolution is the process by which contracting parties settle disagreements. Whether in the form of litigation, arbitration, or other means of mediation, every contract defines a dispute resolution mechanism and jurisdiction. It is the metaphorical Lady Justice, measuring the strength of each party’s arguments, and reaching a decision based on evidence. Smart contracts are unique in this sense. Unlike traditional contracts, they are rigid and deterministic. Written in computer code, nuan...

Until now, proposals to improve blockchain scalability have addressed the problem in one of two ways. One seeks to increase efficiency by optimizing the blockchain or improving the consensus algorithm. The other comes in the forms of layer-2 solutions such as payment channels or side chains. However, none have addressed the core bottleneck to scalability: TCP/IP network limitations. Improving the speed at which blocks propagate through the network is the layer-0 problem few people consider when ...

Privacy and scalability are arguably the most challenging issues blockchains face. Scalable privacy-preserving state machines are inherently difficult. While cryptocurrencies like Zcash have proven trustworthy for simple transactions, privacy in smart contract platforms is an entirely different animal. We’re joined by Guy Zyskind, CEO of Enigma, a platform for scalable decentralized apps which preserves privacy. The Enigma network treats Ethereum smart contracts as “secret contracts” and can per...

One of the key scalability challenges with public cryptocurrency blockchains is that their size grows linearly with the number of transactions. Mature blockchains such as Bitcoin and Ethereum contain >170GB and >1 TB of historical data respectively. New nodes joining these chains need to download this data and verify it in order to become a “full node”. The number of full nodes is a key measure of decentralization, and difficulty becoming a full node translates into future centralization. ...
