Proof-of-Work Mining

The process by which miners expend computational resources to find a nonce producing a block header hash below the current difficulty target, earning the right to append a new block and collect the block reward plus fees. Bitcoin mining uses SHA-256d (double SHA-256) and adjusts difficulty every 2,016 blocks (~2 weeks) to maintain ~10-minute block times. Mining has evolved from CPUs to GPUs to ASICs, with industrial-scale operations dominating the network's hash rate.

Esses ramos mostram quais conceitos esse termo toca diretamente e o que existe uma camada além deles.

Ramo

Prova de Trabalho (PoW)

A consensus mechanism where miners compete to solve computationally expensive puzzles to produce blocks and earn rewards. PoW provides strong security (51% attack resistance) but is energy-intensive. Bitcoin and pre-Merge Ethereum use PoW. The difficulty adjusts to maintain target block times regardless of total network hash power.

Bitcoin

The first decentralized cryptocurrency network, launched in 2009 by the pseudonymous Satoshi Nakamoto, using a Proof-of-Work consensus mechanism and a UTXO-based transaction model. Bitcoin's protocol enforces a fixed supply cap of 21 million BTC, with new coins issued through mining block rewards that halve approximately every four years. It serves as both a peer-to-peer electronic cash system and a store of value, with its scripting language enabling basic programmability such as multisig and timelocks.

Bitcoin Halving

A programmatic event occurring every 210,000 blocks (~4 years) that reduces the Bitcoin block reward by 50%, enforcing a disinflationary monetary policy converging on the 21 million BTC supply cap. The most recent halving occurred on April 20, 2024 (block 840,000), reducing the reward from 6.25 to 3.125 BTC per block. Halvings shift miner revenue composition toward transaction fees and have historically correlated with bull market cycles.

Mempool

The memory pool maintained by each blockchain node containing unconfirmed transactions that have been validated but not yet included in a block. Miners/validators select transactions from the mempool typically prioritizing those with the highest fee rate. Each node's mempool is independent and may differ based on propagation delays; during high-demand periods, the mempool can grow significantly, causing fee spikes as users compete for limited block space.

Bitcoin Layer 2

Scaling and programmability solutions built on top of Bitcoin's base layer that extend its functionality while inheriting some degree of Bitcoin's security. Major approaches include the Lightning Network (payment channels), Stacks (smart contracts via Proof of Transfer), Liquid Network (Blockstream's federated sidechain), and ZK-rollups like Citrea (using BitVM for settlement). These solutions address Bitcoin's limited throughput (~7 TPS) and restricted scripting.

Blockchain Geral

Blockchain

A distributed, append-only ledger that records transactions in cryptographically linked blocks. Each block contains a hash of the previous block, forming an immutable chain. Nodes in the network maintain copies of the ledger and reach agreement through consensus mechanisms. Blockchains enable trustless, decentralized record-keeping without a central authority.

Blockchain Geral

Mecanismo de Consenso

The protocol by which nodes in a distributed network agree on the current state of the ledger. Common mechanisms include Proof of Work (Bitcoin), Proof of Stake (Ethereum, Solana), and BFT variants. Consensus ensures all honest nodes converge on the same transaction history despite potential network delays or malicious actors.

Prova de Participação (PoS)

A consensus mechanism where validators are selected to produce blocks based on the amount of cryptocurrency they have staked (locked) as collateral. PoS is energy-efficient compared to Proof of Work. Misbehaving validators risk losing their stake (slashing). Solana, Ethereum (post-Merge), Cosmos, and Cardano use PoS variants.
