Even before it was used in cryptocurrency, blockchain existed as a concept in computer science. The hash tree or Merkle tree, which Ralph Merkle patented in 1979, was the first form of blockchain. It worked by validating and transferring data between computer systems.
The tech sector has discovered numerous blockchain applications in finance and other critical industries. Blockchain distributed ledger technology can be used to improve data management transparency and reduce fraud.
It enables all customers to gain access to a cloud-based solution, build, host, and use their own blockchain apps, smart contracts, and other functions on the blockchain system, while the blockchain company manages all activities associated with maintaining the functionalities.
