Ingot Protocol
Simple, Private, Versatile Assets
A streamlined protocol for digital assets, inscriptions, and decentralized applications — designed for privacy, simplicity, and seamless Bitcoin integration.
Core Design Principles
Built for simplicity, security, and universal interoperability
Extreme Minimalism
Only 4 lock types, 2 signature schemes. Core L1 validation in ~4,500 lines with 82 passing tests.
Every line is intentional. Validation completes in ~4,500 lines of code with 82 tests — small enough to audit, large enough to matter.
Privacy First
MuSig2 enables indistinguishable multi-signature operations, hiding unused paths through MAST and enhancing anonymity.
Universal VM Support
Ingot runs across Tondi VM, WASM, EVM, and future virtual machines — ensuring interoperability without compromising trust.
Layered Architecture
Clean separation between L1 consensus, L2 indexing, and application layers
L1 Consensus Layer
Transaction validation and security
L2 Indexer Layer
State machine and oUTXO rules
Application Layer
User interfaces and dApps
Transaction Lifecycle
From creation to transfer with optional commit-reveal pattern
Create Asset
Mint new Ingot output with schema, payload commitment, and lock mechanism.
Reveal Payload (Optional)
For large payloads, commit first, then reveal later with CPFP/RBF fee optimization.
Transfer Ownership
Spend old Ingot UTXO, create new one with different owner. oUTXO rules ensure deterministic state.
Real-World Applications
From creative expression to enterprise solutions—Ingot powers innovation across industries
Creative & Cultural
Digital art, collectibles, and cultural expression
Digital Inscriptions
Etch messages, poetry, or data permanently on-chain. Perfect for eternal digital legacies.
NFTs & Collectibles
Mint ERC-721-compatible NFTs for art, music, or virtual items with royalties built-in.
Community Tokens
Launch BRC-20-compatible tokens for projects or communities with low fees.
Gaming Assets
In-game items, characters, and achievements as transferable assets.
Governance & Community
Decentralized decision-making and collaboration
DAO Proposals & Voting
Create proposals for funding or changes, enable weighted voting with privacy.
Multi-Signature Wallets
Corporate treasuries using MuSig2 for efficient, private multi-party control.
Social Media & Content
Build censorship-resistant social feeds with posts as inscribed assets.
Digital Identity (DID)
Create verifiable, self-sovereign profiles following W3C DID standards.
Financial Services
DeFi protocols and advanced financial instruments
DeFi Protocols
Lending, borrowing, AMMs built on Ingot's asset model.
Stablecoins
Algorithmic or collateralized with on-chain governance.
Derivatives
Options, futures, swaps via custom schemas.
Tokenized Securities
Real-world assets (stocks, bonds, commodities).
Prediction Markets
Betting and prediction contracts with custom logic.
Loyalty Programs
Points, rewards, membership tiers as tokens.
Enterprise Solutions
Business infrastructure and compliance tools
Document Notarization
Legal documents, contracts, certificates timestamped and verified.
Supply Chain Tracking
Product certificates, authenticity proofs, provenance records.
Audit Trails
Immutable logs for compliance and regulatory requirements.
Escrow Services
Conditional releases, time-locked funds, dispute resolution.
Intellectual Property
Copyright registration, licensing agreements, royalty distribution.
Cross-Chain Bridges
Asset representations and state proofs for blockchain interoperability.
Universal Blockchain Interconnection
Execute on any VM. Connect every blockchain. True cross-chain composability.
Current Support
Production ready
Planned Integration
2026 roadmap
Cross-Chain Scenarios
Ethereum tokens on Tondi via EVM ScriptHash. Enjoy Tondi's speed and low fees.
Mint on Solana, transfer to Tondi, bridge to Polygon—all with verifiable provenance.
Accept collateral from Bitcoin, Ethereum, and Solana in unified lending pools.
Technical Highlights
Deterministic Instance ID
Uniqueness guaranteed by outpoint (txid||vout). No SALT needed. Simple, deterministic, conflict-free.
Complete MuSig2 Support
Aggregated signatures indistinguishable from single-sig on-chain. 67% space savings for 3-of-3 multisig.
Fail-Closed Security
Unknown fields/enums → transaction rejected. No silent failures. Maximum security through minimalism.
Registry Test Vectors
100% compliance verification across implementations. S1-S6 test suites ensure ecosystem consistency.
