Bitcoin’s approach to solving the double spending problem is to make a collusion and attack on the network prohibitively expensive. One of the main factors that will determine Bitcoin’s chance of survival in the long-term is whether the behavior that maximizes the profits of miners contributes to or sabotages the health of the network.
The game theory that determines this is complex and our understanding of it still incomplete. But research is increasing and two people who have been at the forefront of this work are , a professor in computer science at Cornell University, and Ittay Eyal, a post-doc at the same department.
They joined us for a fascinating discussion of their work on ‘selfish mining’, the incetive structure that underlies Bitcoin and their recent positive conclusions from the Miner’s Dilemma.

As the cost of computing continues to plummet, the number of connected devices is increasing dramatically. In the future powerful computing capacity will be in billions of devices ranging from the lightbulb to the car door to new wearables. This new internet of things (IoT) will dramatically change our lives.
Paul Brody, a Technology Strategist and the former VP of Mobile and IoT at IBM, joined us for a discussion of where the IoT is going. We discussed their white paper on why a decentralized, blockchain-based internet of things could solve the problems of the current IoT in terms of privacy, scalability, and business models.

The cryptocurrency ecosystem is increasingly divided into different camps. There are those betting and working on the eventual mainstream success of Bitcoin. And there are those who take elements of Bitcoin’s technology and repurpose them to improve existing systems.
Hyperledger is one of the projects firmly in the latter camp. They are envisioning a world where innumerable interoperable ledgers are operated by different parties. Hyperledger is their tool for the creation and management of these ledgers. CEO Dan O’Prey and CTO joined us for a discussion of the project, underlying technology and their view of where the cryptocurrency ecosystem is going.

When one is busy driving a technological and societal revolution forward, complying with complicated regulatory requirements is rarely a top priority. Yet, the reality is that at this stage the often ambigious and rapidly evolving regulatory landscape can have an outsized impact on the fate of cryptocurrency startups and on the adoption/integration into existing systems.
Epicenter Bitcoin Regulatory Correspondent and founder of COINsult Siân Jones joined us for an update on the state of Bitcoin regulation in a variety of jurisdiction.

Creating a new token and selling it to fund the development of software has become a preferred way of fundraising for cryptocurrency entrepreneurs. It’s a tempting tool, allowing startups to avoid traditional investors, build a community and allow anyone anywhere to own a stake in the project. For participants, there is the promise of big financial upside and being part of novel undertakings.
Lisa Cheng, whose consulting firm Vanbex has accompanied many crowdsales, joined us for a discussion of this revolutionary way to fund and monetize open source software.

When spinning up a few hundred data-gathering Bitcoin nodes prevented some breadwallet users from transmitting bitcoin transaction, a minor panic quickly erupted about the Bitcoin compliance startup Chainalysis and their supposed sybil attack on the Bitcoin network.
Chainalysis CEO Michael Gronager joined us for a discussion of what happened and what role transaction monitoring will play in the future. We dove deep into the tension between the desires for user privacy and the requirements to achieve integration into existing financial services.

Is Bitcoin secure from attacks that could destroy the currency? To a large part, this is determined by how expensive it is to carry out an attack and by the potential profits the attacker could generate. Ideally, an attack is so expensive to carry out that no profit-driven attacker would engage in it.
But in this episode, Brian argues that the cost of attacking Bitcoin will likely decrease in the future and the ability to short Bitcoin and thus benefit from an attack will increase dramatically.

What Bitcoin did for money, OpenBazaar is trying to achieve for commerce. Born as a fork of the Dark Market project, OpenBazaar aims to facilitate online trade by removing unneeded middlemen. Built as an open source protocol, users simply install the application on their computer to gain access to marketplaces available on the network. From the app, they may also place items or services for sale by creating “Ricardian contracts”, which get propagated to the network and made accessible to everyone to see. The protocol, which uses Bitcoin as a means of payments, utilises multi-signature transactions. This makes it possible for transacting parties to include third-party arbitrators, who may intervene in the event of a dispute. We talked to Brian Hoffman, the project’s Lead Developer, about this paradigm-shifting project and the potential it has to disrupt person-to-person marketplaces such as eBay. Currently in beta, OpenBazaar is due for a full release in Q1-Q2 of 2015.

Levin Keller is known to many in Berlin as the man who warned everyone about the dark scenario where buying Bitcoins in Europe would be subject to VAT. As with the VAT issue, Levin was also concerned with the complexity of filing tax returns. For merchants and companies dealing in Bitcoin, keeping track of gains and losses makes proper accounting a messy ordeal.
His startup, Coyno, hopes to solve that by providing standalone, read-only bookkeeping for your existing wallets. Coyno allows you to import the public seed from your HD wallet and keeps track of transactions. The service, currently in beta, reads your wallets’ public addresses and stores bookkeeping information whenever a transaction occurs. By recording the exchange rate at the time of transaction, Coyno can generate reports of taxable events, allowing users to more easily file their taxes. By allowing Coyno to read all your wallets, it’s able to differentiate incoming and outgoing transaction from funds being moved within your organization, a feature lacking from other reporting tools.
Levin also talks about his journey of being incubated at the Axel Springer Plug and Play Accelerator in Berlin. He also weighs in on some of the challenges of building a Bitcoin startup and attracting investors in Europe.
