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.

Rama

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.

Rama

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.

Rama

Transaction Fee

The cost paid by the sender to have a transaction processed and included in a block. Fees compensate validators/miners for computation and prevent spam. Fee models vary: Ethereum uses dynamic gas pricing (EIP-1559 base fee + tip), Solana uses base fee (5,000 lamports) + optional priority fee, Bitcoin uses fee-per-byte.

Blockchain General

Merkle Tree

A binary tree where each leaf node is a hash of data and each internal node is the hash of its two children. The root hash (Merkle root) uniquely represents all underlying data. Merkle trees enable efficient proof of inclusion—proving a specific element exists requires only O(log n) hashes. Used in blockchains for transaction verification and state storage.

Blockchain Generalmainnet

Mainnet

The production blockchain network where real-value transactions occur. Solana's production network is 'mainnet-beta'. Deploying to mainnet requires thorough testing on devnet/testnet, security audits for significant programs, and careful consideration of upgrade authority management. Mainnet state is permanent and transactions involve real financial value.

Blockchain Generalshielded-transaction

Shielded Transaction

A Zcash transaction where sender address, receiver address, and amount are encrypted using zk-SNARKs, providing cryptographic privacy while allowing network nodes to verify validity without learning private details. Shielded transactions operate within dedicated value pools (Sapling or Orchard), each with independent circuit designs. Users can selectively disclose transaction details to third parties using viewing keys without compromising spending authority.

Blockchain Generalblob-transaction

Blob Transaction (EIP-4844)

An Ethereum transaction type introduced in the Dencun upgrade (March 2024) that carries binary large objects (blobs) of temporary off-chain data. Each blob is 128 KB, committed via KZG polynomial commitments, and stored for ~18 days before pruning. Blob transactions created a separate fee market and reduced Layer 2 rollup fees by 10-100x by providing cheap, temporary data availability.

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.
