EB25 - Mike Hearn: Lighthouse, Assurance Contracts, bitcoinj, Transaction Fees & Core Dev Team
Today our guest is Mike Hearn who many of you are familiar with. He's one of the first Bitcoin users and the developer of BitcoinJ, a Java library used by a number of popular Bitcoin wallets such as the Android wallet, Multibit and Hive. Until recently he was working at Google and is now working full-time on Bitcoin, including an interesting crowdfunding platform called Lighthouse.
Epicenter Bitcoin is hosted by Brian Fabian Crain & Sébastien Couture and is available on iTunes, SoundCloud, Mixcloud, Stitcher and other podcast aggregators.
Today's panel discussion is called "The ever changing landscape of Bitcoin mining" where moderator Jez San is joined by some of the most prominent figures in the mining industry, Marc Aafjes of Bitfury, Dave Carlson of Megabigpower, Timo Hanke of Cointerra and Naveed Sherwani of Peernova. The discussion revolves around several key topics, notably, everyone seems to agree the industry should move away from the term mining and start calling it transaction processing. They also discuss the rapid evolution of ASIC processors in the last year, the importance of improving the overall power efficiency of the network and where ASIC production is heading. They also talk about a highly debated subject which is the shift from home mining to centralised data centers. The panels ends with predictions on the total hashing power of the network at the end of this year.

Volatility has been a great challenge for users of cryptocurrencies. Developing decentralised currencies that track the value of relatively stable indices such as the CPI is one of the hardest, long-outstanding challenges of the crypto-economy.
In this video, I interview a talented developer and theorist, Nikolai Moshegian, who is building Maker, a Decentralised Autonomous “Central Bank” issuing a stable currency called Dai that tracks the value of the SDR (Special Drawing Rights).
Our conversation covered themes such as:
How the Maker system of contracts would work.
How and why would the Dai be stable in value?
What backs the Dai stable coin? What would happen if the backing asset of Dai collapses in value?
Why did Maker not do a pre-sale of their tokens.
Check out the video to get an appreciation of modern approaches to make stable currencies and challenges associated with the same.

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

CoinTelegraph Chief Editor, Allen Scott, and writer, Ian DeMartino join Sebastien (Brian is away) for a conversation about the independent Bitcoin media. Cryptocurrencies enable new business models and monetization opportunities for content producers, which CT is fully utilizing. Allen and Ian explain their innovative system whereby content creators are paid according to the success of their articles, which it determines by measuring the number of shares on social media. CoinTelegraph is an independent news site that specializes in Bitcoin and digital currencies. Freelance writers, who all get paid in Bitcoin, produce the vast majority of their content. CT's long-term ambition is to grow along with Bitcoin and become a front runner in the cryptocurrency news space.

Today's episode is all about Factom, an open source project which aims to solve three core problems which apply to all Bitcoin 2.0 applications: Speed, Cost, and Bloat. Rather than writing every transaction to the blockchain, Factom allows decentralized applications to write blocks of transactions to Factom blocks, which themselves get hashed and stored to the bitcoin blockchain. At its core, Factom provides Proof of Existence, which allows for any digital artifact to be reduced to a hash that proves that artifact's existence at a specific point in time.
We are joined by Factom CEO, Paul Snow, and President, Peter Kirby, to explore the different applications of Factom as well as the technical workings of this very interesting and promissing project.

As is the case with most luxury goods, the diamond industry is faced with the issues of theft, fraud, and counterfeiting. Illegal activity is present at every level of the supply chain, which collectively costs the industry and its insurers hundreds of millions of dollars each year. In recent years, international treaties and regulation have been put in place in an attempt to combat illegal activity, but criminals are most often a step ahead.
Leanne Kemp, CEO of Everledger, joins us to explain how her company is using advanced geological techniques, and blockchains, to bring more traceability to the diamond industry. Everledger, whose clients include many of the largest insurance companies, builds software which allows for a diamond's unique characteristics to be hashed and notarized in the blockchain. Hence, a stone's provenance, and the trail of ownership can be traced, therefore limiting the opportunities for fraud and making it difficult for stolen diamonds to re-enter the market.
Topic's covered include:
- Leanne's background as a technologist
- A broad overview of the diamond industry
- A look at the diamond supply chain
- What roles banks and insurance companies play in the supply chain
- How diamonds are uniquely fingerprinted
- The Kimberly process and other regulations
- Everledger's technology stack and business model
- Other sectors which can also benefit from increased traceability

I caught up with Jamie Burke and Aron van Ammers, who are exploring a really cool direction - credit unions built using smart contracts.
Credit Unions are organisations that match borrowers and lenders that have some level of mutual trust - for example connecting alumni of a university who have liquidity with current students needing liquidity (loans).
We explore how smart contracts could enable the next generation of credit unions through themes such as:
Current challenges with credit unions - underutilisation of capital, governance challenges.
Advantages of moving to a smart contract architecture.
Participants and design of money circle.
Potential challenges with the idea.
The team behind Money Circles.
Check out the video to get an appreciation of how global jurisdiction independent blockchains and smart contracts could enable normal people to better achieve their financial aims and build a better society.

David A. Johnston is a very active member of the Bitcoin community. Aside from speaking at about every Bitcoin conference there is, David is the Managing Director of the DApps Fund, a board member MSC Protocol Foundation, as well as Co-founder and Executive Director of the BitAngels Network.
On this episode we go deep in to decentralized applications, and who better to talk to about DApps than the creator of ""Johnston's Law"" which states ""Everything that can be decentralized, will be decentralized"". We talked to David about the recent whitepaper he co-wrote titled ""The General Theory of Decentralized Applications, DApps"" which defines the different types of DApps and a number of best practices with regards to funding, token distribution, business models etc. We also discussed the DApps Fund, BitAngels Network and the Master Protocol, and his involvement with those projects.
