Update: This article has been edited slightly to clarify that Ethereum's entire programming language has been ported to Counterparty In a major development in the Bitcoin 2.0 race, Counterparty has added the open-sourced custom smart contract features of Ethereum by porting the programming language to the Counterparty platform. While smart contracts have always been possible on Counterparty, they lacked the flexibility and ease of customization found in the Ethereum project. That extra functionality, previously only found in Ethereum, was often attributed by observers of only being....
Amid new concerns about the viability of blockchain smart contracts, one company is releasing a proposal that seeks to make it easier to ensure their security. Developed by Smart Contract Solutions, the open-source Zeppelin project aims to offer a community-driven framework for secure, audited code. The goal is to prevent the unintentional loss of funds, a danger perhaps best illustrated by the collapse of ethereum's biggest smart contract, The DAO. Since ethereum is the best-known smart contract platform, the first set of tools are written in its programming language Solidity. But,....
The life cycle of smart contract development involves crucial steps: create, freeze, execute and finalize. Can a smart contract be destroyed?Yes, smart contracts can be destroyed using the selfdestruct function.Ethereum smart contracts provide a selfdestruct function that allows them to destroy a contract on the blockchain system. It is, however, a two-edged sword for developers. On the one hand, the selfdestruct function allows developers to delete smart contracts from Ethereum and transfer Ether in the event of an emergency, such as an attack. On the other hand, this function might add....
