Great question.
They are functionally equivalent in terms of consensus behavior, but we don’t claim strict implementation-level identity.
The reason we keep both is basically risk management. In a consensus system, even very small differences can have serious consequences. Having the BCHN VM available, which is the same code as the reference implementation, gives a conservative path for users who want maximum assurance.
At the same time, the Knuth VM is built with a different goal in mind. It exposes much richer internals, things like detailed error reporting, execution tracing, stack inspection and metrics. That makes it much more suitable for debugging and building developer tooling, which is hard to achieve cleanly in the reference VM without major changes.
We’ve validated the Knuth VM quite extensively. We ported and adapted the BCHN script test suite, including more than 1,700 script vectors, 23K BigInt tests and VM limits tests. We also ran a full IBD from genesis to tip using the Knuth VM with no checkpoints, verifying every script, and got zero errors.
That gives us a high degree of confidence, but absolute equivalence is very hard to prove, especially because even the process of adapting tests can introduce subtle differences.
If we could guarantee perfect equivalence, we probably wouldn’t need two VMs. But in a consensus-critical system, we prefer to keep that safety net.

@KnuthNode Sounds powerful! Are the VM's functionally equivalent? Why keep two?

🚀 Knuth v0.77.0 is out — and this is a big one.
We just brought our native Script VM back to the frontier.
Knuth is the only Bitcoin Cash node with two VMs:
• A native VM built for developers
• The BCHN consensus VM (same code BCHN runs in production)
👉 Switch between them with a single build flag.
🧠 The upgrade:
Our native VM was way behind. Not anymore.
It now matches consensus rules through the May 2026 upgrade
(we call it Leibniz, BCHN calls it Upgrade 12).
And we didn’t just “update it” — we proved it:
• 1,700+ script test vectors
• 23K+ BigInt tests
• 165 VM limits tests
All ported, adapted, and cross-validated against BOTH VMs.
🔬 Why this actually matters:
This isn’t just another interpreter.
The Knuth VM is built like a real debugger for Bitcoin Script:
• Step-by-step execution
• Breakpoints on opcodes
• Full stack & alt-stack inspection
• Per-opcode error reporting
• Execution tracing through branches
• Metrics: sigchecks, hashes, op cost
👉 This is the kind of tooling Bitcoin Script never really had.
A foundation for debuggers, analyzers, and serious dev tooling.
🧪 Validation:
Full IBD. Genesis → tip.
✔ Knuth VM
✔ No checkpoints
✔ Every script verified
Result: zero errors
🛡️ Don’t trust it yet?
Perfect.
Run Knuth with the BCHN VM — and still get:
• Modern C++23 codebase
• Better networking
• UTXO-Z + improved DB architecture
• Real parallel block validation
(no global cs_main bottleneck 👀)
• Multi-language bindings (C, C#, Python, TS, JS, WASM)
💥 Scale of this release:
PR #188 touched 1,154 files
Yeah… we went all in.

@Bryan10309 "do you disagree with this?"
Yes, I strongly disagree with the assumption that 10x is the most we can do. We can already do 100x with TODAY's tech and improvements are in development.

🚀 Introducing UTXO-Z: A Game-Changing UTXO Database for Bitcoin Cash 📄 Read the full paper: github.com/utxo-z/utxo-z-… I'm excited to share the results of months of research and development from our Scalability Lab initiative (archive.is/T5az0): UTXO-Z, a purpose-built database system that achieves unprecedented performance for Bitcoin Cash nodes. The Challenge: As Bitcoin Cash scales to serve billions of users globally, nodes must validate thousands of transactions per second. Traditional databases like LevelDB become the bottleneck, limiting BCH's potential as peer-to-peer electronic cash for the world. The Solution: UTXO-Z replaces general-purpose databases with a domain-specific architecture optimized specifically for UTXO access patterns. By leveraging cache-optimized data structures, value-based segmentation, and generational storage, we've eliminated the performance penalties that have historically constrained node throughput. The Results Are Staggering: • 33 million lookups/second for recent outputs (45x faster than LevelDB) • 1.5 million lookups/second for complete pipeline (2x faster) • 290,000 inputs/second processed during blockchain sync • 320,000 outputs/second in single-threaded operation • 2.5x higher throughput than LevelDB during initial block download These aren't theoretical numbers—they're real benchmarks on production hardware with actual blockchain data. Technical Innovation: UTXO-Z achieves this through fundamental architectural choices: - Cache-friendly open addressing hash tables - Complete output data stored inline (no pointer chasing) - Temporal locality exploitation through deferred lookups - Memory-mapped files for OS-optimized caching What This Means for BCH: This performance leap provides the foundation for Bitcoin Cash to handle global-scale transaction volumes. No more choosing between decentralization and scale—UTXO-Z ensures nodes can keep up with demand as BCH grows to serve the world. Open Source & Integration: 📄 Full technical paper and details: github.com/utxo-z/utxo-z-… 💻 Source code coming in the next few weeks: github.com/utxo-z/utxo-z Following publication, UTXO-Z will be integrated into the Knuth node and all related libraries, bringing these performance gains to the entire Bitcoin Cash ecosystem. This achievement was made possible by the BCH community's support through the Scalability Lab Flipstarter campaign. Thank you to everyone who contributed to making high-performance infrastructure a reality for Bitcoin Cash. The future of peer-to-peer electronic cash is being built today. UTXO-Z is proof that Bitcoin Cash can and will scale to serve the world. #Bitcoin #Cash $Cash #BitcoinCash #BCH #Scalability #UTXO #UTXOZ

Sneak peek 👀
This is an early look at the new Knuth node interface planned for 2026.
Still work in progress, but the goal is clear: better visibility, better tooling, better UX for node operators and developers.
Curious what you think. Does this direction make sense?

🚀 Knuth v0.74.0 released
This version continues the modernization of Knuth’s core. A lot of the internal code dates back to 2011, and we’re taking the time to update APIs, clean up legacy pieces, enable network tests, and prepare a full rewrite of our P2P and IO handling.
All of this is groundwork for what comes next: CHIPs 2026, UTXO-Z integration, and the larger performance work planned for 2026.
