Blockchain companies in UK

Originally coined by a group of researchers in 1991, blockchain was introduced as an effective measure of preventing the backdating of digital documents. Blockchain also made it harder to tamper with digital documents. It was left mostly idle until Satoshi Nakamoto adopted it in forming a digital currency – bitcoin in 2009. For those specifically seearching for blockchain companies in UK we’ve prepared the shortlist, but first – a brief basics. 

What is Blockchain?

By definition, a blockchain is a chain of blocks containing information. Blockchain works almost like a notary and can be used and understood by the public. The distributed ledger is open to anyone and once data is recorded in the chain, it is almost impossible to change the data.

Each block comes with a unique hash, data and previous block hash used as a personal identifying unit. Stored data depends on the type of block in use. The hash is calculated each time a block is created and if the information is altered or changed inside the block, then the hash also changes.

The original block cannot point to anything previously. Known as the genesis block, it is the mechanism that is solely responsible for the tight security and anonymous feature of blockchains. However, block numbers two to infinity can be traced or changed by changing the hash number of the previous hash.

Blockchain Verification

As a result of the ability to change blocks numbers two to infinity, tampering with any block causes the hash to change. If one block is distorted, all following hashes also become invalid as they no longer store a valid hash. Since development, hashes were used as the main verification angle for blockchain.

Due to security breaches and evolving hacking measures, hashes have proven that they don’t provide the best security. Therefore, blockchains now come with what is known as ‘proof-of-work’ to mitigate the tampering of blockchains.

Proof-of-work is a mechanism that slows down the creation of new blocks. For example, in bitcoin, it takes about 10-minutes to calculate and formulate a new block. Using the proof-of-work mechanism and hashing, blockchain is secured.

Additionally, blockchain uses a peer-to-peer system which is a distributed functionality instead of a central system. This means that everyone is free to join the use of blockchain. New members get a full copy of the blockchain which can be used to verify the functionality of each block added to the blockchain.

Creating a new block means that everyone on the network receives a copy which creates a consensus between all the blocks in the P2P network. Thus, a tampered block is not recognized by the entire chain. It means to hack a chain, one must tamper the entire block system, redo most of the blocks (over 60% of blocks).

There are also smart contracts, which are simple programs stored on the blockchain used to automatically exchange data. Smart contracts work on a set command and cannot be easily manipulated.
