Ethereum: A Secure Decentralized Generalized Transaction Ledger EIP-150 Revision
The combination of blockchain paradigm and cryptographically-secured transactions enable its utility through projects that demonstrate a simple application on a decentralized and singleton computer resource. Such a paradigm is called a transactional singleton machine with shared-state.
Ethereum is a tool that implements such a paradigm which had provides a plurality for the resources. This paper will discuss the design, implementation issues, and the opportunities that Ethereum present in the future.
