When blockchain is used for transactions, with each transaction a person makes — such as sending or receiving funds — the ledger grows. Each new transaction becomes (or forms part of) a "block" that is added to the "chain." What makes blockchain technology so revolutionary is that it’s both secure and can be decentralized. Through using complex cryptography and a consensus between computer servers, transactions can take place between unknown parties without a central authority to grant approval. Blockchain has the potential to reshape the financial services industry — and much more. Here are 10 things you need to know.

A private blockchain is where permission is restricted and only permits a predetermined group of members to access the blockchain. It is also possible to use a combination of the two. It Can Execute Contracts "Smart Contracts" are contracts written in code so that computer protocols facilitate and […]
