How blockchain technology will fundamentally change the Internet. No theorist of the digital age has better explained the next big thing than Don Tapscott. He describes a profound technological shift that will change how the world does business - and everything else - using blockchain technology, which is now used to power the digital currency Bitcoin. The Internet is deeply flawed when it comes to commerce and privacy. Blockchain technology facilitates peer-to-peer transactions without any intermediary such as a bank or governing body. Keeping the user's information anonymous, the blockchain validates and keeps a permanent public record of all transactions. Your personal information is private and secure, but all activity is transparent and incorruptible, stored in code on a digital ledger. With its advent, we will not need to trust each other, because trust is built into the system itself. Many applications of the blockchain require a digital currency, Bitcoin being one application of this great innovation in computer science, but the blockchain can hold any legal document, from deeds and marriage licences to educational degrees and birth certificates, like a World Wide Ledger. It enables smart contracts, decentralized autonomous organizations, decentralized government services, and transactions among things. The blockchain is a truly open, distributed, global platform that fundamentally changes how online transations are done.
