Until a transaction is confirmed in a block, it exists only in the memory pools (mempools) of nodes that have received it." + whatiszeroconftext2: "When you send Bitcoin, the transaction is first broadcast to the peer-to-peer network. Miners then select transactions from their mempools to include in the next block. Only after a transaction is included in a block and that block is added to the blockchain is the transaction considered \"confirmed.\"" + mempool: "Mempools and Transaction Propagation" + mempooltext1: "Each Bitcoin node maintains its own mempool - a waiting area for unconfirmed transactions. When a transaction is broadcast, it propagates across the network as nodes relay it to their peers." + mempooltext2: "Critically, there is no global mempool consensus. Each node independently decides which transactions to accept into its mempool based on its own policies. A transaction in one node's mempool may not exist in another's due to different relay policies, transaction conflicts, or network delays." + mempooltext3: "This lack of mempool consensus is fundamental to understanding zero-conf risks: just because you see a transaction doesn't mean everyone else does, and just because a transaction is in your mempool doesn't mean it will be mined." + doublespending: "Double Spending" + doublespendingtext1: "Double spending occurs when someone attempts to spend the same Bitcoin twice. This is the primary risk that zero-confirmation acceptance exposes merchants to." + zeroconfdoublespend: "Zero-Conf Double Spending" + zeroconfdoublespendtext: "Before a transaction is confirmed, an attacker can broadcast a conflicting transaction that spends the same inputs to a different address. If miners include the conflicting transaction instead of the original, the merchant loses their payment. This attack is relatively easy to execute and requires no special equipment or significant resources." + chaincommitted: "Chain-Committed Double Spending" + chaincommittedtext: "Once a transaction is confirmed in a block, reversing it requires reorganizing the blockchain - an attack that becomes exponentially more difficult with each additional confirmation. This is why multiple confirmations are recommended for high-value transactions." + stucktx: "Stuck Transactions" + stucktxtext1: "Sometimes transactions become \"stuck\" in the mempool for extended periods.

This is useful for payment channels and escrow arrangements where funds should only be accessible after a specific time." + csv: "CheckSequenceVerify (CSV)" + csvtext: "CSV enables relative timelocks - outputs that cannot be spent until a certain number of blocks have been mined since the transaction was confirmed. This is essential for Lightning Network payment channels and other second-layer protocols." + timelockstext2: "While timelocks don't make zero-conf transactions safe for general commerce, they enable sophisticated protocols where the risk of double-spending can be mitigated through economic incentives and cryptographic commitments." + consensus: "The Impossibility of Instant Consensus" + consensustext1: "A fundamental property of decentralized systems is that instant global consensus is impossible. Information takes time to propagate, and different nodes may have different views of the current state at any given moment." + consensustext2: "Bitcoin's solution is to use proof-of-work mining to establish consensus over time. Each block represents agreement on the ordering of transactions, but this agreement only emerges after the fact - not instantly." + consensustext3: "This is why confirmations matter: they represent increasing confidence that the network has reached consensus about a transaction's validity and ordering.
