This document summarizes and discusses different types of blockchain technologies. It begins by explaining Bitcoin's blockchain and then discusses alternative cryptocurrency blockchains using various consensus algorithms like proof-of-work, proof-of-stake, etc. It also covers private and permissioned blockchains being developed by companies for financial applications. Key debates discussed include permissioned vs permissionless blockchains, and whether banks should build on top of Bitcoin or develop private alternatives. The conclusion is that cyberpunk supporters favor scaling Bitcoin, while banks favor private blockchains, so both approaches will likely continue.
Bitcoin and its applications beyond money include digital payments, smart contracts, digital assets, and more. Bitcoin can be used for value transfer like money remittance internationally. New technologies are exploring how to improve the user experience of Bitcoin and other cryptocurrencies. In 2014, over $400 million was invested in Bitcoin startups focused on digital payments, mining, wallets and other applications.
Ethereum is a decentralized platform that runs smart contracts: programs that run exactly as programmed without downtime, censorship, fraud or third party interference. It allows developers to create applications that run on a blockchain similar to bitcoin but designed to allow decentralized applications. Some potential uses of Ethereum include decentralized organizations, identity systems, voting, financial exchanges and crowdfunding platforms.
