25 best blockchain development companies in 2019

Looking for best blockchain companies to hire or to invest into? Well, as for business owner or chief technology officer in today’s highly digitised world, this could be a proper strategy. Bitcoin and blockchain technology remain the red hot topic and a brand new phenomena with potential to change financial sector for years to come.

To explain blockchain we would have to a whole separate article or two, and our purpose here is to list top blockchain developers. Though, to jam it in briefly, Blockchain is a software platform for digital financial assets, where you can store, send and receive cryptocurrencies, like Bitcoin. It all started with Bitcoin.

A brief introduction to blockchain

Blockchain is the high-end technology that verifies digital transactions. In technical terms, blockchain is a series of records/data (blocks), linked in a chronological order and encrypted. This way, data inside is secure, decentralized and impossible to modify.

In other words, online security and resistance to changes are two pillars of blockchain. Every transaction has a key, thus any efforts to alter a transaction sound an alarm by default. Mining is the process of verification and adding new transactions.

 A blockchain developer is typically someone who is a software programmer, first, with knowledge of data structures and architectures, plus some of the blockchain tools, like Ethereum, Hyper Ledger, etc. To help you out and save you time, we’ve prepared a list of best blockchain companies as of 2019.
