# Decentralized Mining and Consensus

## Definition

The process where distributed computers expend energy to cryptographically verify transactions and secure the network, earning new Bitcoin as a reward.

## How it works

Bitcoin operates without a centralized authority, bank, or CEO. To process transactions and secure the network, it relies on a decentralized consensus mechanism known as **mining**.

[[entity-asher-genoot]] explains the mechanics in simple terms:
- Millions of independent computers (miners) distributed globally compete to verify blocks of transactions.
- When a transaction occurs (e.g., sending Bitcoin from one wallet to another), these computers must cryptographically agree that the transaction is valid and that the sender actually holds the funds.
- This prevents the **double-spend problem** — the inability of a digital asset to be spent twice.
- Because the network is distributed across independent actors who do not know or trust each other, no single entity can alter the historical ledger or reverse transactions.

The immense electrical energy consumed by these data centers is the physical anchor that secures the digital network. It is computationally infeasible for a bad actor to rewrite the blockchain because doing so would require out-competing the honest network's energy expenditure.

- The reward miners earn is governed by [[concept-the-halving]].
- The hardware that actually does the hashing is described in [[concept-asic-miners]].
- The robustness of this consensus model is what underlies [[claim-quantum-computing-not-a-threat]]: the speakers argue the network would fork to a quantum-resistant signature scheme before quantum computers could attack.
