BSV Association Announces Chronicle: A Mandatory Network Upgrade That Completes the Bitcoin Protocol

ZUG, Switzerland, April 2, 2026 /PRNewswire/ — BSV Association has confirmed the Chronicle upgrade (SV Node v1.2), a mandatory network upgrade to BSV blockchain scheduled to activate at block height 943,816. Chronicle represents a historic milestone: the final step in restoring the BSV protocol to its original Bitcoin design by removing artificial technical constraints that have long limited what developers and enterprises can build on chain.

The upgrade is available now. All node operators and exchanges running BSV infrastructure must upgrade before the activation block to remain in network consensus.

Connor Murray, BSV Association Head of Stewardship and Standards, said: “Chronicle is not about adding complexity to BSV, it is about eliminating it. By removing the artificial limits that were never part of Bitcoin’s original design, we are handing developers and enterprises a protocol they can build on with real confidence. A stable, unconstrained foundation is what enables serious long-term adoption.”

What Chronicle Enables
Chronicle removes longstanding artificial technical limitations from the BSV protocol, unlocking:

• More flexible Bitcoin Script usage
• More advanced transaction logic
• Greater freedom in application design

For developers, this means building without unnecessary workarounds. For businesses, it means more capable and efficient blockchain-based solutions built on a foundation that will not shift beneath them.

Why Chronicle Matters
Chronicle is not about ongoing protocol change. It is about completing the protocol as originally intended and locking in the stability that long-term value depends on. The result is a leaner development environment with:

• A more stable foundation for long-term development
• Reduced reliance on external dependencies or workarounds
• Lower development overhead
• Greater scalability for enterprise applications

What Operators Must Do Now
All operators of BSV node infrastructure and exchange systems supporting BSV must upgrade to SV Node v1.2 before the activation block height, expected to be reached on April 7^th, 2026. The upgrade is available now and follows the standard node deployment process with no disruption to live systems.

• Nodes that do not upgrade before activation risk:
  • Falling out of network consensus
  • Failing to validate blocks
  • Chain synchronisation issues
  • Disruption to deposits, withdrawals or network connectivity for exchanges running the node software

Wallets, existing applications and standard user transactions are unaffected. Developers are not required to update existing applications. The new functionality Chronicle unlocks is entirely optional and opt-in.

ALL BSV NODE OPERATORS MUST UPDATE BEFORE THE BLOCK HEIGHT IS REACHED. MORE INFO HERE
