In BSV’s UTXO model, an address is not an account or a single balance slot. The same address can be associated with multiple UTXOs, and a wallet balance is simply the sum of those outputs. Understanding this is essential for transaction construction, fee handling, UTXO fragmentation, and privacy.

In BSV, spending does not update a balance. It consumes old UTXOs and creates new ones. Understanding this model helps explain payments, change, transaction chains, and the basic logic behind tokens and application state transitions.

A UTXO, or “unspent transaction output,” is the basic unit of the BSV transaction model. A wallet balance is not an on-chain account field, but the sum of controllable UTXOs. Understanding UTXOs helps explain BSV inputs, outputs, change, fees, double-spending, Script, and parallel processing.

Endian is a common byte-order issue when debugging BSV transactions, especially in raw transactions, TXIDs, outpoints, numeric fields, and Merkle proofs. Understanding the difference between display format and serialized bytes helps avoid false “TXID mismatch” or “proof calculation failed” conclusions.

A raw transaction is the original byte representation of a transaction after protocol-compliant serialization, usually shown as a hexadecimal string. It is central to TXID calculation, signing, broadcasting, and debugging, and is a key concept for understanding how BSV transactions work at the protocol level.

BSV transaction fees are not stored as a separate field. They are calculated as total inputs minus total outputs. Understanding this rule helps developers handle change correctly, estimate fees, manage UTXOs, and avoid accidentally turning remaining balance into fees.

A change output is a key concept in BSV’s UTXO model: old UTXOs must be spent in full, and any unspent amount must be returned to the payer through a new output. This article explains how change works, how it relates to fees, change addresses, privacy, and practical UTXO management.

A TXID is the most common transaction identifier in BSV. It can be used to look up transactions, reference outputs, store business records, and build SPV proof flows. But a TXID identifies the whole transaction, not a specific output, and it does not mean the transaction is final. Real applications should store it together with the output index, status, raw transaction, and proof materials.

A transaction output is a new unit of value created by a BSV transaction, usually consisting of an amount and a locking script. Outputs can represent payments and change, but they can also carry OP_RETURN data, token state, or business records. Understanding outputs, UTXOs, and output indexes is fundamental to understanding BSV transactions and application protocol design.

A transaction input is the funding source of a BSV transaction. It references a specific unspent output from a previous transaction and provides unlocking data. Understanding inputs helps explain the UTXO model, outpoints, double-spend conflicts, fee calculation, and transaction debugging.

BRC-100 is an interface standard in the BSV ecosystem that describes how applications and wallets communicate. It emphasizes that applications express business intent while wallets retain control of keys, helping non-custodial applications request transaction creation, signing, and returned results in a safer and more consistent way.

A BSV wallet is not a traditional account system. There is no single on-chain balance field; instead, the wallet calculates balances and creates transactions by managing private keys, UTXOs, inputs, outputs, signatures, and related data. This distinction is essential for understanding change, multiple inputs, non-custodial wallets, and application authorization.

Mainnet carries real value, while test environments are for learning and development. This article explains the differences between BSV mainnet and test environments, common risks, SDK usage considerations, and practical environment-separation recommendations for project configuration.

WIFs, mnemonic phrases, and HD wallets all relate to key storage, recovery, and derivation, but they mean different things. This article explains their differences, the role of xpubs, and security practices for BSV wallets and application development.

BTC, BCH, and BSV all come from Bitcoin, but their technical roadmaps differ significantly. This article explains why BSV chooses a low-fee, high-volume, large-scale on-chain scaling approach, through the lenses of on-chain scaling, low fees, a stable protocol, SPV, enterprise data, and real-world challenges.

SPV (Simplified Payment Verification) allows lightweight clients to verify that a transaction is included in a block without downloading the full blockchain. This article explains how SPV works, the role of Merkle proofs, what SPV can and cannot prove, and why SPV is a core capability in the BSV architecture.

This article explains the basic mechanics of the BSV network: how transactions are constructed, how blocks organize them, how miners are incentivized, and why BSV places special emphasis on low fees, large blocks, and high-throughput on-chain transactions.

Proof of Work uses a mechanism that is expensive to compute and cheap to verify, allowing miners to compete for new blocks in an open network and using accumulated work to determine the ordering of transaction history. This article explains how PoW works, why miners can order transactions, its security significance, and the miner-economic logic behind BSV’s focus on large blocks, low fees, and high transaction volume.

Blockchain is not just a ledger; it is also a public time-ordering machine. This article explains what the timestamp server means in Bitcoin/BSV, the role of block height and confirmations, and the value of timestamps in double-spend prevention and data attestation.

Peer-to-peer electronic cash is the starting point for understanding Bitcoin and BSV. It emphasizes transferring digital value directly through transactions, signatures, and a public ledger, rather than relying on central platform accounts. This article explains peer-to-peer, cash, double spending, UTXOs, and why BSV emphasizes low fees, high-frequency transactions, and on-chain data.
