Brendan Lee
I'm the world's foremost Bitcoin Script engineer. That's not marketing — it's a statement of fact. There are perhaps a handful of people on the planet who understand Bitcoin Script at the depth required to build truly sophisticated on-chain systems.
I've spent years pushing the boundaries of what's possible with Bitcoin's native scripting language, building tools that make advanced Script development accessible, and helping enterprises unlock the full potential of on-chain computation.
Flagship Projects
BitcoinSX
The most advanced Bitcoin Script IDE, compiler, and simulator ever built. A complete development environment for creating, testing, and deploying sophisticated on-chain contracts.
- • Visual Script debugger with step-through execution
- • High-level language compiler to raw Script
- • Transaction template builder and validator
- • Comprehensive opcode documentation
SonicOrigin
A fractionalization protocol and API for on-chain asset management. Enables complex ownership structures with full on-chain enforcement of rights and restrictions.
- • Fractional ownership smart contracts
- • Automated royalty distribution
- • Programmable transfer restrictions
- • Full REST API for integration
Experience
Founder & Principal Engineer
Building the most advanced Bitcoin Script development tools in the world. Leading development of BitcoinSX and SonicOrigin.
Blockchain Architect
Designed and implemented on-chain solutions for enterprise clients across finance, gaming, and supply chain.
Software Engineer
Full-stack development with increasing focus on distributed systems and cryptographic protocols.
Contract Types I've Built
Over the years, I've designed and implemented a wide range of Bitcoin Script contracts. Here are some of the categories I specialize in:
Payment Channels
Bi-directional payment channels for instant, off-chain transactions with on-chain settlement guarantees.
Multi-Signature Schemes
Complex signing requirements including M-of-N, threshold signatures, and hierarchical approval structures.
Hash Time-Locked Contracts (HTLCs)
Atomic swap primitives enabling trustless cross-chain and conditional payments.
Token Protocols
On-chain token issuance, transfer, and management with full Script-level validation.
State Machines
Complex stateful contracts that evolve through defined transitions, all validated on-chain.
Oracle Contracts
Contracts that incorporate external data feeds with cryptographic verification.
Fractionalization Contracts
Splitting high-value assets into tradeable fractions with enforced rules.
Covenants & Restrictions
Output restrictions that enforce spending conditions across transaction chains.
₿Why Bitcoin (BSV)?
BSV is Bitcoin — the original protocol as designed by Satoshi Nakamoto. It's the only blockchain that scales unbounded, with no arbitrary block size limits, enabling true enterprise-grade applications.
I don't do "crypto." I don't build on chains that sacrifice functionality for ideology. I build on Bitcoin — the peer-to-peer electronic cash system that was always meant to scale to handle the world's transactions.
How I Work
Direct
No hand-waving or buzzwords. I give you actionable, technically precise advice you can implement.
Honest
If something won't work, I'll tell you. If there's a better approach, I'll show you. No sugarcoating.
Global
Based in Brisbane, Australia. I work with clients across all timezones, from startups to enterprises.
