Tenzro Ledger
Settlement Layer for the AI Age
Purpose-built blockchain enabling identity (TDIP/W3C DID), security (TEE-based key management, ZK proofs), verification (credentials, attestations, proofs, inference results), and settlement (all in TNZO).
What is Tenzro Ledger?
Tenzro Ledger is the settlement layer — a purpose-built blockchain for the AI age. It provides the foundational infrastructure for verifiable settlement, identity management, and security attestations required by the Tenzro Network protocol layer.
Built on BFT consensus with sub-second finality and O(n) linear communication complexity, Tenzro Ledger supports three virtual machine runtimes (EVM, SVM, DAML) with unified gas metering and Block-STM parallel execution for maximum throughput.
The TNZO token serves as the native asset for transaction fees (gas), AI inference settlement, validator staking, and on-chain governance. All network fees flow to validators and treasury with automatic EIP-1559 base fee burning.
Multi-VM Execution Runtime
Deploy smart contracts across three virtual machine runtimes with unified gas metering, parallel execution, and shared state management.
EVM
Ethereum-compatible execution with full EVM opcode support, Keccak-256 hashing, and deterministic contract address derivation. Deploy existing Solidity contracts without modification.
- Complete EVM opcode set
- EIP-1559 dynamic gas pricing
- ERC-4337 account abstraction
- Precompile contracts (ecRecover, SHA-256)
SVM
Solana VM support with BPF program execution, PDA derivation, and compute units metering. High-throughput applications benefit from parallel transaction processing via Block-STM.
- BPF program runtime (agave-svm)
- Program Derived Addresses (PDA)
- Compute units metering
- Parallel execution with MVCC
DAML
Canton/DAML runtime for enterprise smart contracts with privacy-preserving execution and multi-party workflows. DAML 3.x compatibility for regulated finance applications.
- Privacy-preserving contracts
- Multi-party workflows
- Canton domain synchronization
- Regulatory compliance primitives
BFT consensus Consensus
High-Performance Consensus
Two-phase consensus protocol (PREPARE, COMMIT, DECIDE) with O(n) linear communication complexity. Sub-second finality ensures rapid transaction confirmation for real-time applications.
TEE-Weighted Leader Selection
Validators with TEE attestations receive 2x weight in leader selection, incentivizing hardware security. Epoch-based rotation ensures fair block proposal distribution across the validator set.
Identity & Verification
TDIP (Tenzro Decentralized Identity Protocol)
Unified identity standard for humans and machines with W3C DID format and verifiable credentials. All identities are on-chain with cryptographic proofs and delegation scope enforcement.
did:tenzro:human:{uuid}KYC tiers, controlled machines, credential inheritance
did:tenzro:machine:{controller}:{uuid}Delegation scopes, capability attestation, auto-provisioned wallets
ZK Proof Verification
Groth16 SNARKs on BN254 curve with GPU-accelerated proving. Hybrid ZK-in-TEE combines cryptographic and hardware attestations. Pre-built circuits for inference, settlement, and identity proofs.
TEE Attestations
Remote attestation verification for Intel TDX, AMD SEV-SNP, AWS Nitro, and NVIDIA GPU. Certificate chain validation ensures hardware integrity. 24-hour attestation report expiry enforced on-chain.
Settlement Infrastructure
TNZO Token Economics
18-decimal precision governance token used for transaction fees (gas), AI inference payments, validator staking, and on-chain voting. Network fee: 0.5% of service payments.
Micropayment Channels
Off-chain payment channels for per-token billing with on-chain settlement finality. Open channel with escrowed TNZO, stream payments, and close with batch settlement to minimize gas costs.
