What Are Hash Functions?

Every transaction in the blockchain world is hashed and bundled together into blocks linked to its predecessor by the hash of the data of the previous block.

Any attempt to change hashed transactions will create a new and different hash that will cause alterations of subsequent blocks. Only 51% of agreements within the community can effect the hash change. If that be the case, a 51% attack may commence. Visit Wallex Custody official website for more details!
