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.
IPFS, the Inter Planetary File System, is an ambitious data transfer and versioning system that seeks to deliver a fast scalable architecture for the next generation of the Web. At Epicenter Bitcoin, we covered IPFS on Episode 100: https://www.youtube.com/watch?v=erB7i6Uc4DM
I caught up with Juan at the Ethereum Devcon and delved into the opportunities enabled by combining IPFS and Ethereum. The discussion veered into the following topics:
How IPFS and Ethereum are synergistic - censorship resistant financial logic coupled with a permanent censorship resistant data web.
Opportunities for synergy - storing Ethereum state in IPFS and storing contract data in IPFs.
Challenges with merging Ethereum and IPFS.
Mutability in IPFS.
Current state and future plans.
Check out the video to gain an appreciation of how you could combine these two powerful systems and build great applications!

Coinapult’s CEO Ira Miller and marketing specialist Freya Stevens join us for a discussion about their company and plans for the future. We particularly dove into their new Locks feature, which allows people to ‘lock’ the value of their bitcoins to other assets such as US Dollar, Euro or gold from directly within the Coinapult wallet. The goal is to remove one often-named barrier to mainstream adoption: volatility.
We also talked about the amazing ‘Let the Bit Drop’ project, which involves sending bitcoin per SMS to every resident of a small Carribean island. A party in Q4 will launch the project and educational materials will be given to residents via government channels.

Backbone to the financial system? Powering decentralized technology? The first true world currency? There is probably who hasn’t dreamt of a world ten years from now when Bitcoin would be all those things. The promise of cryptocurrencies are enormous, but will Bitcoin really emerge as the winner? And how can we reconcile this grand vision for Bitcoin with an ecosystem where projects launch new coins and blockchains every day?
The one project that rekindles those Bitcoin dreams and paints a potential path to Bitcoin’s ultimate success are sidechains. Developed by Adam Back, Greg Maxwell and several other Bitcoin core developers, sidechains aims to allow the permissionless, rapid innovation of alt chains, but using the established monetary base and network of Bitcoin.
It’s a complex project, but with Blockstream founders and sidechains visionaries Adam Back and Greg Maxwell we couldn’t have had better companions on our journey into understanding the coming Bitcoin-Sidechains-Macrocosm. Topics included:
- The motivation behind sidechains
- The concept of digital scarcity
- Concerns about the security of sidechains
- Different stages of sidechains from federated pegs to merged mining to block extension

One of the shortcomings of decentralized smart contracts is their inability to retrieve information from the outside world. The deterministic nature of Etehreum-style blockchains makes it impossible for them to incorporate functions allowing them to do things such as make API calls to websites and data feeds. Though oracles are often cited as the solution to this problem, they require users to place a high level of trust in their operators, a model which would undermine the very nature of a decentralized smart contract.
Ari Juels, a Professor at Cornell Tech (Jacobs Institute) and former Chief Scientist of RSA, joins us to discuss his work on Authenticated Data Feeds for Smart Contracts. These 'Town Crier' feeds would act as bridges between smart contracts and websites, srapping data over TLS and feeding to to a smart contract. Relying on sophisticated hardware enclave technology (Intel SGX), one who uses a Town Crier feed would not need to trust its operator as code execution would be guaranteed signed by the hardware.
Topics discussed in this episode:
- Ari's background in cryptography and cryptocurrencies
- The pain points with oracles as we describe them today
- The idea behind Authenticated Data Feeds
- The hardware and software architecture of the Authenticated Data Feed model and how hardware isolation works
- How Authenticated Data Feeds could be used to create criminal smart contracts
- The differents ways in which criminals could use Authenticated Data Feeds to release bounties for crimes such as private key theft or even murder
- Countermeasures which may prove effective in fighting criminal smart contracts
- The Initiative For Cryptocurrencies & Contracts (IC3) and its raison d'être

One of the key innovations of Bitcoin is the ability to easily implement payment channels. A number of use cases have been discussed or demonstrated, among which is the idea of pay-per-use. This is particularly useful when charging for things like WiFi or streaming video by the second. With this in mind, one could imagine a line of communication between two peers, where data flows in one direction and payments flow in the other.
This is the idea behind Streamium, a free and open-source service which allows content creators to stream live video directly to viewers, and get paid instantly. We’re joined by Manuel Aráoz and Esteban Ordano, the two brilliant software engineers from Argentina who created Streamium. They have worked together on numerous Bitcoin projects these past few years, including ProofOfExistence.com, Faradam, Decentraland, RelayStore, and actively contributed to the BitCore javascript library.
Topics covered include:
- The current state of Bitcoin in Argentina
- The general idea behind Streamium, how it works and its technical components
- How payment channels are implemented in Streamium and its various use cases
- The Faradam project
- The prospect of alternative content funding models made possible by Bitcoin micropayments
- Proof-of-existence and what innovations blockchain technologies brings to data notarization
- The Decentraland project and the vision for a blockchain-based virtual reality

In the last year, blockchain protocols have matured at an exciting pace. Open source projects like Ethereum, the Eris stack and Tendermint are behind much of the experimentation being conducted at leading companies. These protocols would not be where they are today if it wasn't for the hard work of dedicated open source developers.
One of those people is Rick Dudley. An opinionated and passionate developer, Rick is involved in multiple projects. He works as a DevOps at Monax, works closely with Vlad Zamfir on implementing Casper in Ethereum, is a leading member of the Coala organization and is Founder and CEO of the startup Vulcanize. Rick gives us insider insights on Ethereum and on how the project may evolve, in particular, once Casper is implemented and when more robust, strongly typed language VMs are made available to the protocol.
Topics discussed in this episode:
- How Rick got involved with blockchain and Ethereum
- His views on the Ethereum's planned transition to Casper
- The risks and benefits of moving to Casper
- The subtle differences between Casper and Tendermint
- The recent break up of the Synereo project
- Greg Meredith's work on Rchain and Rholang, and how that relates to Ethereum
- Potential synergies between Zcash and Ethereum
- Vulcanize and VulcanizeDB

Oracles are a fundamental conduit for moving data from the real world into the Ethereum blockchain. Without great real world data Ethereum would lose much of its utility.
I talk to Thomas Bertani, who is building a provably honest centralised oracle service for Ethereum. This design really caught my eye as it combines the cheapness of a centralised oracle with excellent security guarantees that we have grown to love about decentralised technologies.
The conversation covered themes such as:
What is a provably honest oracle?
How is Oraclize provably honest?
What is TLS Notary technology?
Current state and applications of Oraclize.
Check out the video for understanding a really cool and potentially transformative oracle design.

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.
Topics included:
- The recent statement by the UK’s treasury on digital currencies
- How the Isle of Man keeps pioneering a cryptocurrency-friendly environment
- The stance of the FATF (Financial Action Task Force) towards Bitcoin
- The insanity of the looming BitLicense rules and difficult-to-predict consequences they may have

One of the sectors which is ripe for disruption is the real estate industry. In the US for instance, a handful of historic and very powerful players operate what is known as MLS, or Multiple Listing Services, and hold unofficial monopolies on residential and commercial real estate listings. Brokers, who depend on these listing services to sell properties, agree that their incumbent positions have created a situation where fees have continued to rise, while little to no added value has been added for their users.
Stephen King and Russel McLernon join us to explain RexMLS, a decentralized Multiple Listing Service built on Ethereum and IPFS. Currently in beta, the DApp would allow brokers to list properties at a very low cost, and be accessible to international markets, something which is lacking in the current model.
Topics discussed in this episode :
- The basics of MLS or Multiple Listing Services
- What is RexMLS and the problems it is trying to address
- The benefits of a decentralized MLS
- The different technical components of RexMLS
- Why they chose Ethereum and IPFS
- The user experience of RexMLS
- The product's roll-out phases
- How users are incentivized to participate in the system
- The RexDex token exchange and the token injection model
- RexMLS's governance model
