How the algorithm manages the blockchain

When talking about algorithms in the context of blockchain, it is most often referring to Proof of Work – this mechanism allows the Bitcoin network to function reliably. But what exactly is an algorithm?

The Basis of Computer Processes

An algorithm is essentially a sequence of clear instructions aimed at solving a specific task or achieving a particular goal. In computer science, it represents a set of unambiguous commands executed by a computer to process data, perform calculations, or make decisions.

The range of application of algorithms is extremely broad – from simple operations, such as subtracting two numbers, to complex calculations, for example, finding the optimal route between geographical points. Mathematicians and programmers are constantly developing new algorithms to solve specific problems, and their significance goes far beyond pure computer science – they are used in biological neural networks and electronic devices.

Structure and Evaluation of Algorithms

Each algorithm has a clearly defined starting and ending point, generating results based on the input data and programmed steps. To solve more complex problems, several algorithms can be combined together, although this requires additional computational resources.

Researchers evaluate algorithms based on two main criteria. The first is correctness, meaning the accuracy of the work and the ability to solve the given problem. The second is efficiency, which is determined by the amount of resources and time required to perform a specific operation. To compare different algorithms, the method of asymptotic analysis is used, regardless of the programming language or hardware.

The Role of Algorithms in Cryptography

In the context of blockchain, the algorithm takes on critical importance. Proof of Work for Bitcoin is not just a mechanism, but a fundamental component of mining that verifies and confirms all transactions on the network. This algorithm protects the network from attacks, ensures its integrity, and allows the decentralized system to function without a central authority.
