Bitcoin is the first successful internet money based on peer-to-peer technology; whereby no central bank or authority is involved in the transaction and production of the Bitcoin currency. It was created by an anonymous individual/group under the name, Satoshi Nakamoto. The source code is available publicly as an open source project, anybody can look at it and be part of the developmental process. Bitcoin is changing the way we see money as we speak. The idea was to produce a means of exchange, independent of any central authority, that could be transferred electronically in a secure, verifiable and immutable way. It is a decentralized peer-to-peer internet currency making mobile payment easy, very low transaction fees, protects your identity, and it works anywhere all the time with no central authority and banks. Bitcoin is design to have only 21 million BTC ever created, thus making it a deflationary currency. Bitcoin uses the SHA-256 hashing algorithm with an average transaction confirmation time of 10 minutes. Miners today are mining Bitcoin using ASIC chip dedicated to only mining Bitcoin, and the hash rate has shot up to peta hashes. Being the first successful online cryptography currency, Bitcoin has inspired other alternative currencies such as Litecoin, Peercoin, Primecoin, and so on. The cryptocurrency then took off with the innovation of the turing-complete smart contract by Ethereum which led to the development of other amazing projects such as EOS, Tron, and even crypto-collectibles such as CryptoKitties.
FANTOM is a new DAG based Smart Contract platform that intends to solve the scalability issues of existing public distributed ledger technologies. The platform intends to distinguish itself from the traditional block ledger-based storage infrastructure by attempting to employ an improved version of existing DAG-based pro-tocols. The FANTOM platform adopts a new protocol known as the “Lachesis Protocol” to maintain consensus. This protocol is intended to be integrated into the Fantom OPERA Chain. The aim is to allow applications built on top of the FANTOM OPERA Chain to enjoy instant transactions and near zero transaction costs for all users. The mission of FANTOM is to provide compatibility between all transaction bodies around the world, and create an ecosystem which allows real-time transactions and data sharing with low cost.
