Stay ConnectedEpicenter brings you in-depth conversations about the technical, economic and social implications of cryptocurrencies and blockchain technologies. Every week, we interview business leaders, engineers academics and entrepreneurs, and bring you a diverse spectrum of opinions and points of view.
Epicenter is hosted by Sebastien Couture, Brian Fabian Crain, Friederike Ernst, Meher Roy and Felix Lutsch. Since 2014, our episodes have been downloaded over 8 million times.

Bitmain is one of the most well known, and one of the most polarizing companies in the blockchain space. The largest ASIC manufacturer and operator of several mining pools, Bitmain is the center of many controversies and discussions around centralization in the space. But not only is it the subject of discussion, Bitmain breaks out of the “passive miner” stereotype and is very active in many of the discussions in the community, most notably the Great Scaling Debates.
In this episode, we sit down with Nishant Sharma, Head of Community Relations, who is responsible for acting as a bridge between the Bitmain company and the many communities it interacts with through its mining and ASIC operations. We explore the origins of Bitmain and its founders, the economics of ASIC production, its past and current relationships with different communities, and the future of the company.

As the cryptocurrency space has grown, exchanges have become the dominant juggernauts of the industry. One of the earliest and most reputable exchanges is Kraken. From the company's formation in 2011, Kraken has grown to 4m users and almost 1,000 employees.
We are joined by Kraken Founder and CEO Jesse Powell. We dove into the history of Kraken, their values and the vision that's driving them.

The vision of a world computer on which anyone can deploy smart contracts has captured our imagination since the publication of the Ethereum whitepaper. But while Ethereum demonstrated the viability of the concept, its shortcomings in terms of capacity and throughput prevent it from realizing the vision. Today, throughput has become a major bottleneck for widescale adoption of decentralized technologies.
Many projects have set out to deliver where Ethereum 1.0 falls short. Most projects, including Ethereum 2.0, aim to create some kind of sharded network with many interoperable chains. Solana may be the only project that went the other way. Through identifying every performance bottleneck for a single blockchain and developing novel ways of removing them, they target to achieve throughput of 50,000 tps.
We were joined by Solana creator and CEO Anatoly Yakovenko to discuss Solana's approach to building a web-scale blockchain. We covered some of their novel ideas including proof-of-history and parallelizing smart contract execution.

Blockchain and cryptocurrencies have the potential to change the world in meaningful ways. And this change may drastically impact people’s lives – both for the better and for the worse. While ethics are often discussed for technologies like AI, the ethical considerations around blockchain technologies have received less focussed attention.
We’re joined by Rhys Lindmark, Head of Community and Long-Term Societal Impact at the MIT Media Lab’s Digital Currency Initiative. Previously the host of the podcast “Creating a Humanist Blockchain Future,” Rhys’ approach to blockchain was always about considering its potential impact. Since joining the DCI, his podcast, now “Gray Mirror,” continues to explore these questions. He has also recently started teaching a blockchain ethics course with the DCI’s Director, Neha Narula.

This past year, we have witnessed what some are calling a “Cambrian Explosion” in zero-knowledge proof systems. New proof systems based on a variety of cryptographic assumptions are popping up every week. And while zero-knowledge systems are known for their privacy-preserving characteristics, they have proven particularly useful for scaling blockchains through off-chain computations.
We're joined by Eli Ben Sasson, Co-founder and Cheif Scientist in the East at Starkware. His company is developing a full proof-stack, which leverages STARKs. Pioneered by Eli, STARKs are zero-knowledge cryptographic proofs, which are succinct, transparent, and post-quantum secure. StarkWare has demonstrated how zkSTARKs may be leveraged to provide off-chain scalability by generating proofs of computational integrity which may be verified on-chain.

We’re joined by Yoni Assia, Founder and CEO of eToro. The concept behind this world-leading social trading platform is users invest smarter by automatically copying the top traders in the community. With over 10 million users, over a trillion dollars traded on the platform just last year alone, this fascinating approach to trading is making huge waves. A decade after its original launch, eToro entered the crypto space with eToroX, their crypto exchange. More recently, they added cryptocurrencies to the growing list of assets that users can add to “Copy Trades.” Yoni shares his long-term vision in which he sees the tokenization of all traditional asset classes eventually taking place.

Those who have been in crypto long enough remember the not-so-good-ol’ days when an air-gapped machine was the only way to store private keys securely. Thankfully, the wallet space has come a long way from that era. But we still live in a world where the seed phrase is the single atomic point of failure. Enter threshold signatures schemes (TSS), a multi-party computation (MPC) where different parties generate a key and are all required to create a valid signature.
We’re joined by Omer Shlomovits and Ouriel Ohayon, Co-founders of ZenGo. Their product is a ‘keyless’ crypto wallet, which means users never need to generate or store a key which gives them access to their funds. Keys are created with an MPC, where both ZenGo and the user are required to sign a transaction. TTS opens up exciting new possibilities like social recovery, user permissions for teams, and inheritance planning schemes. The important distinction between ZenGo and existing multi-signature wallets is that they achieve this using only cryptography, and do not rely on on-chain elements like smart contracts or op_scriptSig in Bitcoin.
Topics covered in this episode:
- Omer and Ouriel’s respective backgrounds in academia and online consumer-facing products
- What lead them to want to build yet another crypto wallet
- The state of custody in the crypto wallet ecosystem and the challenge which remain unaddressed
- A quick refresh on cryptographic primitives and multi-party computations (MPC)
- The building blocks of cryptographic signatures and threshold signature schemes (TSS)
- How TSS is different from Bitcoin multi-sig and smart contract multi-sig
- TSS in ECDSA vs. Schnorr signatures
- Applications and use cases for TSS
- ZenGo’s on-boarding, restore process and use of biometrics
- The future of wallet interoperability in a world of proprietary cryptographic schemes
