What is Blockchain Technology?


Story Highlights

  • What is blockchain?

  • Let’s compare DNA and Blockchain.

Blockchain, is a public registry is not stored centrally and distributed among the various nodes in the network. Information is recorded in blocks. Each new block is linked to the previous one. Changing the information in one block is impossible without changing the whole chain. The registry stores the entire transaction history. Transactions here are understood as any events: money transfers, registration of property rights, performance of any works, etc.

For simplicity, we can imagine this technology, for example, in the form of common Google document, in which each new entry in the list depends on the logical connection to all the previous ones. Another popular comparison is the DNA chain, where each transaction is a microscopic molecule containing information about the entire living organism. Due to this unauthorized data change is impossible: the system does not agree and reject the operation, as the body rejects the foreign cells and tissues. The record of each transaction is based on the execution of a certain algorithm, which contains data on the conditions of the event (transaction), confirmed by all its participants.

When I first got acquainted with the technology of Blockchain, I could not help feeling deja vu. Somewhere I already saw it! Something painfully familiar, almost from the school desk And only after a while, I realized that the creation of Satoshi Nakamoto has an analog in living nature. This is a DNA molecule. Deoxyribonucleic acid (DNA) is a macromolecule (one of the three basic, the other two – RNA and proteins) that provides storage, transmission from generation to generation, and the realization of a genetic program for the development and functioning of living organisms. DNA molecule stores biological information in the form of a genetic code consisting of a sequence of nucleotides. DNA contains information on the structure of various types of RNA and proteins. DNA contains information on the structure of various types of RNA and proteins.

Let’s compare DNA and Blockchain.

In the Blockchain information is recorded as a rigid, unchanging sequence of individual blocks. DNA consists of a rigid sequence of genes. The Blockchain protection system is based on multiple copies of the archive and its distribution across multiple media. Malicious changes made on one medium are quickly eliminated after comparison with data from other medium.

The DNA molecule is copied an astonishing number of times – it is in every cell of a living organism. Damage to one DNA molecule is also corrected by the remaining cell array with the original genome.

It is possible to make changes in whole Blockchain have to take control over half of the archive media. Accordingly, changes in the genome are also possible in the case of identical mutations in a significant number of DNA molecules.

Nakamoto transferred biological mechanisms to the digital space. I wonder if he did it consciously or there was an accident? Until now, the technological development of mankind has gone, mainly, away from the solutions proposed by nature. Evolution did not lead to the appearance of a wheel, a steam engine or a TV. But our attempts to replicate the energy-efficient process of photosynthesis have failed.

And so, intuitively, the solution was proposed in many ways “ideologically” similar to the natural mechanism. This makes people look at the Blockchain on the other side. Now there are discussions about the fate of the Blockchain, and it turns out that this is a technology that has been tested by a billion years of evolution.

A bit tricky interpretation, but worthy of attention. So, Blockchain is a record of Internet transactions, because now many people start using crypto-currencies. Compare with DNA. This fixation of genetic codes, gradually becoming more complicated with time. The same thing happens with the Blockchain. Any Blockchain (Bitcoin, Ether, Ripple) is similar to a specific kind (homo sapiens, primates, etc.).

The Blockchain can branch out to create a competitor currency – just like two different species in the past had one ancestor. Of course, transformation into DNA takes time, but the construction of a Blockchain is also not an easy one. Natural selection and the evolutionary process a bit like “mining”, that is, a series of complex steps, which creates something amazing and incredible
