Are blockchain developers in demand?

Bitcoin is a cryptocurrency that relies on the blockchain to record all of its transactions. When computers connected to the blockchain use their computing power to process these transactions, they get paid with a percentage of the Bitcoin. Each block represents one such transaction. Bitcoin is only one digital currency that relies on the blockchain. A growing number of additional "coins" rely on the same decentralized process. Also, blockchains can process other transactions and store other information in a decentralized and public way. Therefore, blockchain is much bigger than Bitcoin.
