Understanding mining: definition and fundamental mechanisms
At the heart of the functioning of blockchains like Bitcoin or Ethereum, mining is the technique that allows validating and adding new blocks of transactions to the chain. Through this process, miners provide their computing power to solve complex cryptographic problems called hash functions. The first machine to find the valid solution obtains the right to create the next block, which grants it a reward in cryptocurrency, for example, freshly minted Bitcoins.
The technological foundation of mining is based on the so-called “proof of work” (PoW) consensus. It ensures the security and decentralization of the network by requiring participants to invest computing power. This mechanism prevents double spending and secures illegitimate transactions, thereby ensuring trust in the blockchain.
Technical functioning of mining
Mining involves solving cryptographic puzzles through a hash algorithm. Each block contains a set of transactions as well as a reference to the previous block. Miners use various hardware—from powerful GPUs such as those produced by NVIDIA and AMD to specialized devices like Bitmain’s Antminer—to intensify their computing capacity.
A network of nodes distributed worldwide verifies the validity of created blocks, ensuring the integrity of the decentralized ledger. As the network grows in size, the difficulty of mining increases, pushing miners to invest in more powerful equipment to remain competitive.
Differences between types of mining
- GPU Mining: Use of graphics cards to simultaneously process multiple calculations, particularly popular for currencies like Ethereum.
- CPU Mining: Exploiting the power of central processors, suitable for less complex cryptocurrencies or those resistant to ASIC and GPU.
- ASIC Mining: Using specific integrated circuits to mine only one cryptocurrency, often one with a standardized hash algorithm, primarily for Bitcoin.
- Cloud Mining: Renting remote mining power, convenient to avoid technical complications but with higher risks.
