Craig Wright Revives Bitcoin’s Fixed Protocol Debate

Craig Wright has reignited one of Bitcoin’s oldest ideological disputes, arguing that its base protocol should be permanently fixed to prevent developers, miners, corporations or foundations from changing its rules.

In a series of posts on X, Wright claimed Bitcoin was designed as an open system in which competition occurs above an immutable protocol.

He accused supporters of developer-led upgrades of defending “rule by committee” while describing fixed rules as centralized.

The comments revive the conflict between protocol stability and adaptability. Bitcoin supporters generally agree that no single party should control the network, but they disagree over whether preventing all future changes would strengthen decentralization or leave the protocol unable to respond to vulnerabilities and new technical demands.

Wright Says Fixed Rules Would Push Power to the Edges

Wright argued that Bitcoin’s protocol should provide stable conditions under which anyone can transact, build services or accept payments without seeking approval from a central organization.

“The base rules remain stable while competition above them remains unlimited,” he wrote, adding that changing the protocol should not itself be considered innovation.

In his view, developers should create products and competing implementations without requiring the broader network to adopt their preferred rules.

Now think carefully about what that means.

Many of you called me a fraud for arguing that Bitcoin should remain an open system with a fixed protocol—one in which anyone can transact, build, compete and accept payment without seeking permission.

Wright also criticized artificial capacity limits, claiming they push users toward exchanges, custodians and other intermediaries.

His position closely reflects the philosophy associated with Bitcoin SV, which supports much larger blocks and attempts to preserve what its advocates describe as Bitcoin’s original design.

Under this model, no developer group could introduce upgrades that alter transaction processing or network economics. Businesses could consequently invest without fearing that a future protocol change might undermine their services.

Bitcoin Changes Require Broader Network Adoption

Bitcoin’s existing governance system is less centralized than Wright’s criticism implies. Developers can write code and propose changes through Bitcoin Improvement Proposals, but they cannot independently force the network to accept them.

Node operators choose which software to run, while miners, exchanges, wallet providers and users decide whether to support new rules.

Imagine thinking Bitcoin was supposed to be governed by a small group of developers who can change the rules, isolate dissenters and gradually degrade the protocol—then calling that decentralisation.

Bitcoin was designed to be the opposite.

The protocol should be fixed so that…

Upgrades generally require broad coordination because incompatible changes can split the network into competing chains.

Segregated Witness demonstrated this complicated process. The upgrade modified how certain transaction data is handled, increasing effective capacity and addressing transaction malleability.

It was proposed through the open-source development process, but required support across the ecosystem before activation.

Critics of permanently fixing Bitcoin argue that some capacity for change is necessary. Software vulnerabilities, cryptographic threats, and unexpected economic behavior may require protocol-level responses. Removing all upgrade mechanisms could make the network more stable but potentially more brittle.

Supporters of greater immutability counter that this flexibility gives influential developers and companies disproportionate agenda-setting power, even when they cannot unilaterally impose changes.

Wright’s intervention remains controversial because of his previous claim that he created Bitcoin under the name Satoshi Nakamoto.

In 2024, the UK High Court ruled that Wright was not Satoshi, did not write the Bitcoin white paper, and did not create the original software.

The judge found that Wright had fabricated his claim and supported it with forged documents. A subsequent judgment recounts the court’s conclusion that the evidence against his claim was overwhelming.

A court later found Wright in contempt for breaching an order related to further litigation and handed him a suspended 12-month prison sentence.

Those rulings establish that Wright is not Bitcoin’s creator, but they do not resolve the governance question raised by his latest posts.

The dispute instead exposes a fundamental trade-off: permanently fixed rules can limit institutional control, while carefully coordinated upgrades can protect and improve a changing network.

Bitcoin’s current model attempts to balance both by making changes possible but difficult to impose without broad consent.
