Although blockchain is commonly associated with Bitcoin, there are lots of other cryptocurrencies based on the same technology, the leading among them being Ethereum.Although there are some significant technical differences between the two, the most important distinction to note is that Bitcoin and Ethereum differ substantially in purpose and capability. Bitcoin offers one particular application of blockchain technology, a peer-to-peer electronic cash system that enables online Bitcoin payments, whereas Ethereum emerged to correct some of the main criticisms that were made towards Bitcoin – especially in terms of security. What it accomplished was to ensure and provide safer transactions, more flexible contracts that are compatible with any wallet, as well as short block times to ensure easier confirmation of transactions.Ethereum is more available than bitcoin. More than two-thirds of bitcoins have already been mined, whereas access to ethereum is still widely available. Ethereum is a more secure, flexible, easy to use, and transact altcoin. It has brought innovation in terms of investment and entrepreneurship. Unlike Bitcoin blockchain that is used to mine and transact bitcoin, the Ethereum blockchain focuses on running the programming code of any decentralized application.
