Blockchain Geral

Contrato Inteligente

Self-executing code deployed on a blockchain that automatically enforces the terms of an agreement when conditions are met. Smart contracts are immutable once deployed (unless upgradeable), transparent, and trustless. On Solana they're called 'programs'; on Ethereum they're written in Solidity and run on the EVM. They enable DeFi, NFTs, DAOs, and other decentralized applications.

Grafo conceitual

Veja o termo como parte de uma rede, não como uma definição sem saída.

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

Ramo

Programa

Executable code deployed on-chain, equivalent to a smart contract on other blockchains. Programs are stateless—they store no data themselves but read/write data in separate accounts they own. Programs are compiled to SBF bytecode and loaded via the BPF Loader. Every program has a unique Program ID (its account's public key).

Ramo

EVM (Ethereum Virtual Machine)

The stack-based virtual machine that executes smart contracts on Ethereum and EVM-compatible chains (Polygon, Avalanche, BSC, Arbitrum). Programs are compiled to EVM bytecode from Solidity or Vyper. The EVM is single-threaded—all transactions execute sequentially. In contrast, Solana's SVM supports parallel execution and uses a register-based design.

Ramo

Solidity

The primary programming language for Ethereum smart contracts. Solidity is statically typed, supports inheritance, and compiles to EVM bytecode. Unlike Solana's Rust-based development, Solidity uses a contract-oriented paradigm where code and state are co-located. Neon EVM enables running Solidity contracts on Solana by emulating the EVM.

CSD (Central Securities Depository)

Institution holding securities in electronic form as central ownership registry. Examples: DTCC (US), Euroclear (Europe). On blockchain, the token program serves as a permissionless alternative — the ledger itself maintains the ownership registry.

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.

Blockchain Geral

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.

Blockchain Geral

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.
