What is Moca Chain?
Moca Chain is a Layer 1 EVM-compatible blockchain purpose-built for decentralized identity, enabling chain-agnostic identity data issuance and verifications.
Moca Chain is built upon EVMOS (a cosmos-sdk EVM implementation) and integrates with BNB Greenfield’s decentralized storage system, while running its own identity oracle to relay data across different chains.
This enables Moca Chain to become the single source of truth for identity data since it:
- Houses all the credential and identity-based smart contracts
- Manages the decentralized storage where credentials are stored
- Enables users to relay proofs crosschain

CometBFT Consensus Layer
Moca Chain utilizes CometBFT consensus and is governed by $MOCA holders as they participate to decide the future direction of the ecosystem:
- Community members can submit governance proposals with a minimum deposit requirement
- Proposals enter a voting period
- Proposals must meet minimum participation thresholds
- Approved proposals are automatically executed on-chain
Cosmos SDK with EVM Compatibility
Moca Chain integrates Cosmos SDK with Ethereum Virtual Machine (EVM) functionality through EVMOS, creating a unified environment:
- Cosmos $MOCA and EVM $MOCA are the same currency, managed by the same bank keeper module
- Each EVM address (e.g., 0x1234...7890) has a corresponding Cosmos address (mocachain1qwe...7890)
- The EVM runs the LONDON instruction set, with support for some SHANGHAI opcodes, including:
- EIP-3855
- EIP-3860
- EIP-1153
- EIP-5656
- EIP-6780
Moca Chain Storage Provider Network (MCSP)
Moca Chain includes a built-in decentralized storage layer called MCSP network inspired by BNB Greenfield:
- Payload data is stored by independent Storage Providers
- Object metadata, payments, and permissions are recorded on-chain
- Users and DApps interact via S3-compatible APIs to upload, download, and manage objects
- Data availability is protected through replication and integrity proofs
- Providers earn storage fees for service, with penalties for misbehavior
- Enables verifiable, cost-efficient storage for Moca Credential System and broader applications
