Smart oracles provide a simple, flexible way to implement ‘smart contracts’, which encode business logic, laws, and other agreed-upon rules. Smart oracles build on the idea of oracles, or entities that provide smart contracts with information about the state of the outside world, and combine information gathering with contract code execution. In such a system, […]
With the help of many members of the community, I have written this short book for beginners, entrepreneurs and risk-takers who having heard of a bitcoin or cryptocurrency, but knowing little about it want to understand how algorithms can constrain governance and transfer value in a consensus-driven, voluntary manner.
One of the central challenges for mathematical cryptography is to create a payment system that provides the advantages of cash in a digital world. In this expository article we describe two very different solutions to this problem. The first is an elliptic-curve-based version of a construction of Brands, and the second is Bitcoin. We also […]
The DAO (Distributed Autonomous Organization) intended to fund Slock.it has raised $130m worth of ETH: over 13% of Ethereum’s total market capitalization. Almost two weeks remain.
An overview of DACs and a step by step look at how they function.
Ethereum is a pioneering blockchain that first supported the execution of arbitrarily complex smart contracts.
