Bitcoin surely does serve a great purpose for it’s users. It’s decentralized, pseudo-anonymous, and secure. As we know, the Bitcoin protocol is based on the revolutionary blockchain technology which solves multi-decade long problem tracking of unique digital assets without a centralized ledger. Up to this point, the solution was to use a centralized entity in order to validate transactions, but blockchain technology enables us to keep track of each individual’s assets on a decentralized programmatic level.
Some companies have taken that blockchain technology and are implementing it to create other decentralized services besides a currency.
