How the BSV Network Works: Transactions, Blocks, Fees, and Miner Incentives

If you remember only one sentence, make it this: users create transactions, miners validate and package transactions, blocks record batches of transactions, and fees plus block rewards jointly incentivize miners to maintain the network.

That is the most basic economic loop of Bitcoin/BSV. Once you understand it, you can understand why transactions carry fees, why block size is debated, and why BSV places particular emphasis on low fees and large-scale on-chain transactions.

First, the Overall Flow

A typical path for a transaction through the network looks like this:

User/application → create transaction → broadcast transaction → miner validation → include in a block → receive rewards and fees

This process looks simple, but it effectively determines how the entire network operates.

What Is a Transaction?

A transaction is the basic unit of action in Bitcoin/BSV.

It can express many things:

Transfer BSV from one control condition to another
Create new UTXOs
Spend old UTXOs
Write data, such as OP_RETURN data

More precisely, a transaction is not simply a statement like “Alice gives Bob 10 satoshis.” Instead, it references previous outputs as inputs and then creates new outputs.

For example:

Input: a 100-satoshi UTXO that Alice previously received
Output 1: 30 satoshis to Bob
Output 2: 69 satoshis in change back to Alice
Fee: 1 satoshi

Here, the fee is not a separate field. It is calculated as:

Fee = total inputs - total outputs

This is also key to understanding the Bitcoin/BSV ledger model.

What Is a Block?

A block is a collection of transactions.

A block typically includes:

A block header
The hash of the previous block
A Merkle root
A timestamp
Difficulty-related fields
A nonce
A list of transactions

The purpose of a block is not simply to “store things.” Rather, it places transactions into a historical record that is ordered, backed by proof of work, and linked to what came before and after. This is why a blockchain can serve as a verifiable and traceable ledger structure.

What Do Miners Actually Do?

Miners can also be understood as transaction processors. Their main responsibilities include:

Receiving transactions
Verifying whether transactions are valid
Selecting transactions to include
Building candidate blocks
Performing Proof of Work
Broadcasting a new block to the network after finding one

Miners receive two types of income:

Block subsidy: newly issued BSV under the protocol
Transaction fees: the difference between the inputs and outputs of user transactions

Over time, the block subsidy decreases. The long-term security model of the Bitcoin system requires fees to become more important gradually. In other words, the network cannot rely forever on new issuance alone; the transaction market must gradually take on a larger incentive role.

Why Does BSV Place So Much Emphasis on Low Fees and High Transaction Volume?

This is central to understanding BSV’s roadmap.

In the BTC approach, block space is scarce, fees can become high, and on-chain transactions are more like high-value settlement.

In the BSV approach, the goal is for blocks to carry large numbers of low-fee transactions. Each transaction can be inexpensive, but if total volume is large enough, miners can still earn revenue.

A simple analogy:

High-fee, low-volume: each ticket is expensive, but there are few attendees
Low-fee, high-volume: each ticket is cheap, but there are very many attendees

BSV chooses the low-fee, high-volume path, which is why it particularly emphasizes:

Large blocks
Low transaction fees
Data transactions
Enterprise applications
Teranode high-throughput node architecture

The premise of this path is that on-chain capacity is large enough to accommodate real business traffic at greater scale.

Why Must Fees Exist?

Fees serve at least three purposes:

Incentivizing miners to process transactions
Preventing unlimited spam transactions
Helping miners select transactions when block space or processing capacity is limited

BSV’s ideal is not “no fees,” but fees low enough to support micropayments and high-frequency data transactions. This distinction matters: low fees are not zero fees; they make on-chain transactions commercially sustainable.

Why Does Block Size Lead to Different Roadmaps?

Block size determines how many on-chain transactions a chain can directly carry.

If Blocks Are Small

Node resource requirements are lower
It is easier for ordinary users to run full nodes
Transaction capacity is limited
Fees may rise
More applications are pushed off-chain or to Layer 2

If Blocks Are Large

On-chain capacity increases
Fees may remain low
Node operating costs rise
Higher demands are placed on network propagation, storage, and validation capacity
Miners and nodes may become more specialized

BSV accepts more specialized roles for nodes and miners in exchange for greater on-chain throughput. This marks a clear cultural difference from BTC: the former places more emphasis on scaling and on-chain capacity, while the latter places more emphasis on scarcity under resource constraints and conservative scaling.

Common Misunderstandings

Misunderstanding 1: Fees Are Part of the Transfer Amount

They are not. A fee is not an additional output. It is:

total inputs - total outputs

Misunderstanding 2: Miners Can Create More BSV at Will

They cannot. Miners can only claim the block subsidy and fees according to the protocol rules. Invalid new issuance will be rejected by other nodes.

Misunderstanding 3: Bigger Blocks Are Always Better

Not necessarily. Larger blocks mean higher capacity, but they also impose higher infrastructure requirements. The debate around BSV lies in this point: BSV argues that specialized infrastructure can handle this scaling, while critics worry it may introduce centralization risks.

Summary

The core logic of the BSV network can be condensed into three points:

Transactions are the basic unit, used to transfer value and write data
Blocks organize transactions into an ordered and verifiable historical record
Miners are incentivized through block subsidies and transaction fees, thereby maintaining the network

BSV’s chosen path places emphasis on low fees, large blocks, high throughput, and on-chain capacity. Understanding this helps explain why it emphasizes enterprise applications, data transactions, and high-frequency payment scenarios.
