Interview with Roman Mandeleil of Ether Camp at DEVCON1 in London
In this interview, I chat with Roman Mandeleil, core developer at the Ethereum Foundation. He leads the development of EthereumJ (Java implementation of the Ethereum yellow paper), Ether Camp Ethereum Block explorer, Ether Camp Integrated Development Environment and Hack Ether Camp Hackathon.
Roman walks us through:
His background and the work he has done with Ethereum Functionalities of the Ether Camp IDE The upcoming Distributed Ethereum Hackathon on December 1.
Check out the video and consider participating in the hackathon. The hackathon itself is managed by the Ethereum blockchain, and this automates the judgement process and payment of rewards. It is a really cool concept.

For many the promise of decentralized applications and DAOs is to be beyond the limitations and rigidity of the existing legal system. There is no question that where DAOs can roam freely, innovation can accelerate. But can the law, courts and regulations be left behind so easily?
Lawyer Stephen Palley joined us to discuss what happens when the new and old worlds collide and how courts will look at what goes on in the land of DAOs and DApps.
Topics covered included:
- Whether trust is reduced, removed or just shifted elsewhere in blockchain systems
- If creating decentralized applications could create liability risks
- Why courts will impose a legal structure if a formal one doesn't exist
- The concept of jurisdiction and how it could affect DAOs
- Why one should be careful with saying a DAO provides insurance

From BitShares to his central role during the inception of Ethereum Charles Hoskinson has continually influenced key projects in the blockchain and cryptocurrency space. After departing the Ethereum project in 2014, he has recently stepped back into the limelight by pledging support and resources to turn the fledgling Ethereum fork ETC into a viable project.
Charles joined us together with Alex Chepurnoy, a developer at his company IOHK. Besides Ethereum Classic, we talked about IOHK and Scorex, IOHK's modular blockchain framework project that Alex Chepurnoy has been leading.
Topics covered included:
- The vision and activities of IOHK
- Scorex: A Modular Blockchain Framework
- Conflicts of vision that lead to Charles' departure as original CEO of Ethereum in 2014
- Why the hard fork broken Ethereum's social contract
- Why ETC should differentiate and find its own path
- The role governance could play in ETC's future

The lack of an explicit governance mechanism has created deep problems for Bitcoin. Ethereum, with the DAO-related soft/hard-fork discussions, may face similar challenges ahead. Yet, already in 2014 Arthur Breitman quietly started working on cryptocurrency network Tezos that has an explicit mechanism to let coinholders vote on protocol upgrades.
Our discussion with Breitman centered around how explicit governance could lead to a more secure and evolutionary protocol. We also discussed Tezos' approach to smart contract that tries to prevent bug-riddled and insecure smart contracts such as the DAO which has thrown Ethereum into a deep crisis.
Topics covered included:
- Why stakeholders voting on forks can prevent consensus attacks
- The mechanics of Tezos' governance
- How an upgrade mechanism could allow Tezos to rapidly and radically evolve
- Why the programming language in which smart contracts are written is crucial for security
- Why a functional language that allows formal proofs such as OCaml is more suited for smart contracts than Ethereum's solidity
- The road ahead for Tezos

I talk to Christoph Jentzsch of Slock.it, an ambitious German startup that is merging IoT with the Ethereum blockchain. Slock enables owners of smart devices to rent out their devices using smart contracts on Ethereum. This automates significant sections of the sharing economy.
In addition, Slock is designed as a Decentralised Autonomous Organisation (DAO). Our conversation focused on:
The vision behind Slock
How blockchain and IoT are synergistic technologies.
The technical architecture of Slock.
Some monetization ideas
Watch the video to see an amazing service that clearly demonstrates how the blockchain can take IoT and the sharing economy to the next level.

Years into the controversy around how to scale Bitcoin, there have been many challengers to Bitcoin core's dominance. After XT, Classic and others have faded, Bitcoin Unlimited has been gaining traction and emerged as plausible new way forward.
Bitcoin Unlimited wants to make the block size a parameter that is set by miners and nodes, but not fixed at a network level. They argue a natural fee market would emerge, allowing Bitcoin to rapidly scale and realizing its promise of electronic cash as well as store of value. The project is also member-driven, with democratic decisions driving its development decisions.
Core developer G. Andrew Stone and Bitcoin Unlimited President Andrew Clifford joined us for the episode.
Topics discussed in this episode:
- How Stone and Clifford first got involved in Bitcoin
- The history of the blocksize debate and Bitcoin core alternatives
- Why the Bitcoin block size should be determined by miners not developers
- The natural fee market that would arise controlling the size of Unlimited blocks
- How the non-profit organization behind Bitcoin Unlimited works
- How a transition to Bitcoin Unlimited could look like

Mehdi Medjaoui (Co-founder and COO) & Elie Chevignard (CMO) are the two guys behind Oauth.io, a service which aims to provide a simple and standardized way for developers to implement Oath. Working in digital identity management, they have an interesting proposal on how to build personal identity management into the blockchain. This proposition would effectively take the power away from centralized single sign on services like Facebook and Google and make them decentralized.

In the crowded race to become the leading ‘Bitcoin 2.0’ platform, Counterparty has stood out by avoiding fancy crowdsales and instead building a platform that works. The protocol, which sits on top of Bitcoin and thus benefits from the security of its mining power, allows issuing assets, paying dividends or trading in a decentralized way. Over the past year, it has been the platform of choice for many crowdsales and is also what powers LTBCoin.
Co-Founder Robby Dermody joined us for a discussion of the features and evolution of the project.
Topics covered included:
- Why they create the initial XCP supply by destroying bitcoins
- What the different components of the Counterparty system are
- What distinguishes embedded consensus systems like Counterparty
- Why crowdfunding has become a major use case for Counterparty
- Why Counterparty’s Ethereum-style smart contracts will play an important role in the future
- Their new company Symbiont, which aims to commercialize Counterparty's technology
