On-Chain Reputation & Trust Infrastructure for DeFi
InSoBlok is on-chain reputation and trust infrastructure for Web3: a purpose-built L2 blockchain, a Trust Computation Engine, and on-chain attestation contracts that make reputation portable and programmable across 20+ EVM and non-EVM networks. Protocols use it as a reputation oracle to gate access, weight governance, price risk, and settle conditionally on verified trust.
Key facts
- Purpose-built L2 with sequencer + validator network for trust anchoring
- Trust Computation Engine across six signal domains
- On-chain Trust Attestation Registry with O(1) verification
- Portable attestations across 20+ EVM and non-EVM chains
- Delivered via on-chain feeds, off-chain APIs, and ZK privacy methods
- Backed by 23.1M+ wallets scored, 324M+ transactions analyzed
What is on-chain reputation infrastructure?
On-chain reputation infrastructure is the set of services — scoring engines, attestation contracts, and oracles — that let smart contracts and apps read and act on how trustworthy an address is. InSoBlok provides this as sovereign infrastructure: it computes trust off-chain, anchors verifiable attestations on-chain, and serves them as a reputation oracle so any protocol can make trust programmable.
Why build on InSoBlok
| Capability | InSoBlok | Typical alternatives |
|---|---|---|
| Architecture | Dedicated L2 + attestation registry | Single contract or off-chain only |
| Verification | O(1) on-chain verification of trust state | Re-compute off-chain each time |
| Portability | Attestations across 20+ chains | Locked to one chain |
| Privacy | ZK selective disclosure | Public raw data |
| Delivery | On-chain feeds + API + SDK | API only |
| Governance | Score-weighted, sybil-resistant | Token-weighted only |
What you can build
Trust-gated access
Require a minimum reputation to enter pools, mint, or use features.
Reputation-priced DeFi
Adjust rates, collateral, and limits dynamically by on-chain score.
Score-weighted governance
Weight votes by reputation and sovereignty tier to resist sybils.
Conditional settlement
Settle or release funds only when trust conditions are met on-chain.
Portable identity
Carry reputation and DID across 20+ chains via signed attestations.
How it works
Compute
The Trust Computation Engine scores addresses from six signal domains.
Anchor
Verifiable attestations and Merkle roots are anchored on the InSoBlok L2.
Consume
Your contracts read trust via the oracle; apps read via API/SDK.
Act
Gate, price, weight, or settle on verified, privacy-preserving trust.
Who it’s for
- DeFi protocols pricing reputation into lending and perps
- L2s and appchains adding a native trust layer
- DAOs building sybil-resistant governance
- Identity and access platforms needing portable reputation
- Infrastructure teams integrating a reputation oracle
Frequently asked questions
Is InSoBlok an oracle or a full chain?
Both. It runs a purpose-built L2 with its own sequencer and validators, and it serves trust as an oracle via on-chain feeds, off-chain APIs, and ZK privacy methods.
How is reputation portable across chains?
Trust attestations are signed (EIP-712) and anchored on-chain, so reputation built on the InSoBlok L2 can be resolved and verified across 20+ EVM and non-EVM networks.
Can contracts verify trust cheaply?
Yes. The Trust Attestation Registry is designed for O(1) on-chain verification of O(n) trust state, keeping gas predictable.
Can we keep scores private?
Yes. ZK-SNARK selective disclosure lets users prove thresholds or attributes without revealing the underlying data.
