Ethereum and Oracles
One of the more popular proposals for implementing smart contracts differently from the way they are typically presented in Ethereum is through the concept of oracles. Essentially, instead of a long-running contract being run directly on the blockchain, all funds that are intended to go into the contract would instead...

the ethereum project: learning to dream with open minds
βAnd those who were seen dancing were thought to be insane by those who could not hear the music.β Friedrich Nietzsche Ethereum as a project is more than just a technology, even if technology is at its core. In the rush of creating, co-creating and debugging everything you sometimes...

One of the annoyances of the blockchain as a decentralized platform is the sheer length of delay before a transaction gets finalized. One confirmation in the Bitcoin network takes ten minutes on average, but in reality due to statistical effects when one sends a transaction one can only expect a...

During the run-up to the ether sale we will be releasing a series of blog posts regarding our development plans and intended organizational structure. Today we describe some of the background details of the ether sale module. The sale module will be displayed on our website at https://www.ethereum.org for the...

The topic of mining centralization has been a very important one over the past few weeks. GHASH.io, the Bitcoin network's largest mining pool, has for the past month directed over 40% of the Bitcoin network's hashpower, and two weeks ago briefly spiked over 50%, theoretically giving it monopoly control over...

Writing effective decentralized applications in Ethereum is at the same time easy and hard. The easy part we all know: rather than needing to create your own blockchain, manage complicated database code, deal with networking and NAT traversal, or any of the other complexities involving writing a peer-to-peer app from...

Decentralization, n. The security assumption that a nineteen year old in Hangzhou and someone who is maybe in the UK, and maybe not, have not yet decided to collude with each other. There has been a large amount of ruckus in the past week about the issue of mining...

Development of the Ethereum project has gone very well over the months since inception. The core activity β development of the software platform β is on track and many developers around the world are starting to build small, exploratory distributed applications on the platform, even though we are still not...

Although truly solving blockchain scalability fundamentally, that is to say figuring out a solution to the problem that every node must process every transaction, is a very hard problem, and all suggested solutions rely on either highly advanced cryptography or intricate multi-blockchain architectures, partial solutions that provide a constant-factor improvement...

One of the challenges when creating a new cryptocurrency is figuring out what the distribution model is going to be. Who is going to receive the currency units, at what time, and what is the mechanism that decides? Despite the crucial importance of this question, there has actually been comparatively...

Our current proof of work design, blockchain-based proof of work, is the second iteration of our attempt to create a mining algorithm that is guaranteed to remain CPU-friendly and resistant to optimization by specialized hardware (ASICs) in the long term. Our first attempt, Dagger, tried to take the idea of...

One of the most popular topics in the digital consensus space (a new term for cryptocurrency 2.0 that Iβm beta-testing) is the concept of decentralized autonomous entities. There are now a number of groups rapidly getting involved in the space, including Bitshares (also known as Invictus Innovations) developing βdecentralized autonomous...

The idea of releasing a new currency as a mechanism for funding protocol development is perhaps one of the most interesting economic innovations to come out of the cryptocurrency space. In the past twenty years, we have seen a growing centralization in the protocols that underlie the internet, with the...

Ether (ETH), the cryptofuel that powers distributed applications on the Ethereum platform, will be issued at a constant annual linear rate via the block mining process. This rate is 0.3 times the total amount of ETH that will be purchased in the pre-sale. While the best metaphor for ETH...
