Initial Coin Offerings (ICOs) powered by the Ethereum blockchain platform are the hottest thing going right now, but are they secure? Ethereum provides appealing smart contract and payment options for a lot of industries. This Microsoft Azure template deploys a single Ethereum client with a private chain for development and testing. This public ledger (chain of blocks) is called the ‘Blockchain’. A blockchain is made up of a bunch of blocks of transactions that contain a timestamp and a pointer to the previous block (such that they form a chain). However, some denial of service attacks are possible if block validation is too slow. The rest are consigned to the dustbin of history. At first, a lot of people wrote it off as “just another Bitcoin imitator,” but then they realized this cryptocurrency has some truly unique features.

Through five new tools built into their consortium network project, a company would be able to develop complex smart contracts for use across many business applications. In practice, the execution of a smart contract happens as long as the contract has enough fees to cover the network resources it utilizes. Ethereum’s smart contract can save the day in such a situation. Ethereum’s current version, Homestead, leverages a proof-of-work based consensus algorithm, rewarding computers that contribute to its security in the same way. The Nakamoto consensus is a solution to a problem in computer science illustrated by the tale of the two byzantine generals. Here, thus, lies the empowering function of public blockchains. Ripple, on the other hand, has quietly poised itself as the main contender to grab an enormous market, with potential to expand into IoT applications or other similar value transfer opportunities down the line. They can be massively decentralized or partly decentralized,” he said.
