Passkey / WebAuthn Wallet

A blockchain wallet that uses the WebAuthn/FIDO2 standard for authentication via biometrics (fingerprint, face) or hardware security keys instead of seed phrases. Passkey wallets require smart contract accounts that verify P256 (secp256r1) signatures, as WebAuthn uses a different curve than Ethereum's native secp256k1. Coinbase Smart Wallet and Solana's native secp256r1 precompile are major implementations.

Estas ramas muestran qué conceptos toca este término directamente y qué existe una capa más allá de ellos.

Rama

Account Abstraction

A design pattern that replaces the rigid externally-owned account (EOA) model with programmable smart contract wallets capable of custom authentication, gas sponsorship, and batched transactions. ERC-4337 implements this on Ethereum via UserOperations, bundlers, an EntryPoint contract, and paymasters. EIP-7702 (Pectra upgrade, May 2025) extends this by allowing EOAs to delegate to smart contract logic.

Rama

Billetera

Software or hardware that manages cryptographic keys and enables users to sign transactions, view balances, and interact with dApps. Hot wallets (Phantom, Solflare, Backpack) are internet-connected for convenience. Cold wallets (Ledger, Trezor) store keys offline for security. Wallets don't actually 'hold' tokens—they hold the private keys that control on-chain accounts.

Point (Validator Rewards)

A weighted credit unit used in Solana's validator reward calculation regime. Points represent the product of a validator's vote credits and its active stake, determining its proportional share of the epoch's inflation rewards. Validators with more stake and more vote credits accumulate more points, translating to higher absolute rewards distributed at epoch boundaries.

OP_CAT

A proposed Bitcoin opcode (BIP 347) that would reintroduce byte-string concatenation to Tapscript, originally disabled by Satoshi Nakamoto in 2010 due to DoS concerns now mitigated by Tapscript's 520-byte stack element limit. OP_CAT would enable covenants (spending conditions constraining future transactions), Merkle proof verification, and more expressive smart contracts on Bitcoin. The proposal was assigned BIP 347 in April 2024 and is live on Signet for testing.

Blockchain General

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 General

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 General

Prueba de Participación (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 General

Prueba de Trabajo (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.
