About blockchain

Blockchain is a way of storing data that makes it difficult or impossible to alter, hack, or deceive it. A blockchain is a shared database of duplicated transactions and distributed through the network of operating devices that make up the blockchain. Blockchain as a Service (BaaS) is a blockchain service that enables users to use cloud-based platforms to create, access, and host their blockchain apps, functions, and smart contracts. As part of BaaS, a cloud-based service vendor conducts tasks to keep the system operating and agile. A blockchain is a growing collection of documents, known as blocks that are cryptographically connected.

A cryptographic hash of the previous block, a clock, and transaction data are all included in each block (generally represented as a Merkle tree). The timestamp proves that the transaction data occurred when the block was written to get into the hash. A blockchain is a distributed, and public digital archive made up of documents called blocks used to record transactions through several computers and ensure that no one block can be updated without disrupting all subsequent blocks. Each subsequent block confirms the previous ones by using the previous block's hash, forming a series. Consequently, since the data in any given block, once registered, cannot be modified retroactively without affecting all subsequent blocks, blockchains are resistant to code manipulation.  

Blockchain technology addresses critical problems such as network trust. Any company will concentrate on addressing the challenges at hand by adjusting the main criteria, trust. Governments around the world have recognized its significance and are eager to adopt blockchain technologies. It provides many benefits like better transparency, enhanced security, reduced costs, accurate traceability, improved speed, and high efficiency.
