Epicenter - Learn about Crypto, Blockchain, Ethereum, Bitcoin and Distributed TechnologiesClement Lessage & Federico Ast: Kleros – Crowdsourced Arbitration for Blockchain ApplicationsDispute resolution is the process by which contracting parties settle disagreements. Whether in the form of litigation, arbitration, or other means of mediation, every contract defines a dispute resolution mechanism and jurisdiction. It is the metaphorical Lady Justice, measuring the strength of each party’s arguments, and reaching a decision based on evidence.
Smart contracts are unique in this sense. Unlike traditional contracts, they are rigid and deterministic. Written in computer code, nuances in human language and vagueness of terms do not exist in this realm. There are no judges, no jury, just calculated execution.

Epicenter - Learn about Crypto, Blockchain, Ethereum, Bitcoin and Distributed TechnologiesUri Klarman: bloXroute – Layer-0 Scaling with the Blockchain Distribution NetworkUntil now, proposals to improve blockchain scalability have addressed the problem in one of two ways. One seeks to increase efficiency by optimizing the blockchain or improving the consensus algorithm. The other comes in the forms of layer-2 solutions such as payment channels or side chains.
However, none have addressed the core bottleneck to scalability: TCP/IP network limitations. Improving the speed at which blocks propagate through the network is the layer-0 problem few people consider when thinking about scaling.
Fundamentally, network bottlenecks are what prevent blockchains from increasing their transaction throughput. Raising the block...2018-08-151h 20

These programs, which are executed by the entirety of the network, enforce the rules described within the code. Effectively, in this realm, code is law. And as we’ve seen recently, altering the outcome of that code after it has been deloyed, should we later realize that it was flawed or did not produce an intended result, can be messy. In addition, there are instances where human intervention can be necessary or even desirable. Take a mortgage agreement for example.

This makes most cryptocurrencies a poor instrument for storing value, and introduces complexities when making purchases in fiat amounts. Stable cryptocurrencies include mechanisms which allow them to stay pegged to fiat currencies like the US Dollar or Euro. They present a number of advantages, and, in addition to taking the headache out of making purchases, can be used by cryptocurrency traders who need a stable unit of account for hedging their assets.

Maxing out only a handful of operations per second, there have been many proposals to scale it up so that it can compete with existing distributed database technologies. As the blockchain’s demand continues to increase, it’s unclear if the Bitcoin protocol will ever be able to handle thousands, if not millions of transactions per second. BigchainDB is taking a different approach. Rather than trying to scale up blockchain technology, it starts with a big data distributed database, RethinkDB, and adds blockchain features and characteristics.

We have talked about Multchain and OpenChain in the past, but Tendermint promises to be a viable solution for many permissioned blockchain use cases. It’s design is modular, meaning that the application layer (smart contract) and the consensus layer are completely independent. This provides added flexibility and allows for business logic to be written in practically any programming language. In addition, its unique approach to consensus, a round-robin Proof-of-Skate algorithm, is much better suited for permissioned blockchain sc...2016-01-111h 18
Epicenter - Learn about Crypto, Blockchain, Ethereum, Bitcoin and Distributed TechnologiesCasey Kuhlman: Permissioned Blockchains and Disrupting Industrial Application DesignPermissionable blockchains have gained much attention from enterprise this past year, and specifically, the traditional fiance and FinTech sectors. As new protocols emerge and the technology is matures, it is becoming apparent they are simply a new class of database, one which integrates business logic (smart contracts) and a consensus layer (PoS, PoW, etc).
is the CEO of Eris Industries, a company which specializes in building permissioned blockchain systems for enterprise. Their aim is to deliver the technologies which enable companies to easily build and deploy applications which make use of blockchain and smart contract technologies.

Epicenter - Learn about Crypto, Blockchain, Ethereum, Bitcoin and Distributed TechnologiesTim Pastoor: Identifi – Rethinking Identity as a Decentralized Web of TrustIdentity is probably one of the most important constructs in our society. In our modern world, protecting one’s identity has become complex, as we no longer rely solely on governments to prove who we are. In addition, most identity sources can be easily compromised. Credit cards and social security numbers weren’t developed with the Internet in mind, and other identifiers such as logins and passwords aren’t well suited truly secure authentication and authorisation.
We’re joined by Tim Pastoor, Founder of 2way.io, to discuss how we can improve control of our identities using concepts...2015-12-141h 04
Epicenter - Learn about Crypto, Blockchain, Ethereum, Bitcoin and Distributed TechnologiesThe Big Chain PowwowThe Bitcoin and blockchain industry has been through a lot this year. While the Bitcoin price has experienced relative stability, perhaps indicating slow growth, the space has grown into a rich and diverse ecosystem of startups and open technologies. Through inspiring proof-of-concepts and exciting use cases, blockchain technologies have gained legitimacy as a viable technology to improve transparency, reduce costs and optimise processes, to name a few of it’s benefits.
In this episode, all three Epicenter Bitcoin hosts, Brian, Sebastien and Meher, come together to look back on the events which marked the space this past ye...2015-12-081h 20
Epicenter - Learn about Crypto, Blockchain, Ethereum, Bitcoin and Distributed TechnologiesEmin Gün Sirer & Ittay Eyal: Bitcoin-NG – Scientists Versus the ChurchOne of the concerns confronting the Bitcoin community is that of scaling the transaction throughput rate: How do we go from the current rate of approx. 5 transactions per second to a thousand times that?
In this episode, we talk to Emin Gun Sirer and Ittay Eyal from Cornell University regarding Bitcoin NG; a next generation Bitcoin blockchain design that addresses some protocol based limitations preventing Bitcoin from increasing transaction throughput.
Their proposal also enables fast (initial) transaction confirmations on the order of 10-20 seconds.
Topics covered in this episode:
Metrics to measure...2015-11-021h 09
Epicenter - Learn about Crypto, Blockchain, Ethereum, Bitcoin and Distributed TechnologiesMuneeb Ali & Ryan Shea: Onename – Bringing Decentralization to Identity with Blockchain IDA brilliant fact about crypto-economic blockchains is that they enable the construction of naming systems that transcend limits imposed by Zooko’s triangle. Traditional naming systems such as human names, Domain Name System (DNS) and Facebook profile names are subject to Zooko’s triangle and cannot be secure, human memorable and decentralised at once. For instance human names such as Meher Roy are human-memorable and decentralised but not secure (nothing prevents hundreds of people being called Meher Roy). Domain Names like are secure and human-memorable but require a central authority to hand out names.

Epicenter - Learn about Crypto, Blockchain, Ethereum, Bitcoin and Distributed TechnologiesEsteban Ordano & Manuel Aráoz: Streamium – Pay-Per-Second Video Streaming for Indie ProducersOne 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...2015-10-051h 11
Epicenter - Learn about Crypto, Blockchain, Ethereum, Bitcoin and Distributed TechnologiesPaul Sztorc: Truthcoin & Prediction Markets – From Information-Overload to Crowd IntelligencePrediction markets are considered one of the most promising applications of blockchain technology. Although the concept and some early implementations have existed for years, decentralized prediction markets present a number of advantages to their centralized counterparts.
joins us to discuss Truthcoin, a “Peer-to-Peer Oracle Protocol which absorbs accurate data into a blockchain so that Bitcoin-users can speculate in Prediction Markets”. We dive deep to explore the advantages of decentralized prediction markets, their various real-world applications, and their potential to revolutionize the creation and propagation of knowledge in our society.
On this episode, we are thrilled to i...2015-09-211h 18
Epicenter - Learn about Crypto, Blockchain, Ethereum, Bitcoin and Distributed TechnologiesDan O’Prey & Daniel Feichtinger: Hyperledger Decentralized Ledger PlatformThe 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 wher...2015-04-061h 09
