On-Chain Registry: Cosmos-SDK Asset List

As blockchain assets transition between various chains within the Cosmos ecosystem and beyond, the need arises for a precise tool to monitor this intricate data flow. Meet the On-Chain Registry (OCR) – meticulously designed to compile all proof-of-nodes data, offering a timely and detailed snapshot of the current asset landscape.

Proof-of-Nodes Concept

Rather than a static registry, the OCR represents a living, constantly updating protocol that sources data straight directly from nodes. This mechanism leads to:

• Accuracy: The registry furnishes complete and precise data, crucial for meaningful and successful blockchain transactions.
• Reliability: By ruling out the chance of human error, the registry delivers consistent information that users can rely on.
• Inclusivity: It leaves out no data not specified in the chains, thereby offering a comprehensive overview of the blockchain environment.

Functionality

OCR provides an interface for updating, storing, and accessing data on-chain. This enables it to dynamically adapt to the ever-changing state of the chains.

API & IBC Tokens Verification. OCR functions as a robust and secure API, offering users the capability to verify Inter-Blockchain Communication (IBC) tokens with trusted and verified metadata. This feature further enhances the transparency and security of cross-chain transactions.

Integration of External Registries. In the pursuit of providing an all-encompassing data access point, OCR integrates data from other registries as well. This guarantees that users have a comprehensive, unified, and updated view of the entire blockchain ecosystem.

Assets

On-chain based data allows viewing of all existing assets:

• chain-registry like data
• csv data
• contracts (code, schema)
  • bostrom (example of asset query)
  • osmosis-testnet (example of asset query)

Asset Data Structure

OCR uses a chain-registry like asset data structure for better compatibility.

Differences from the chain-registry asset data structure:

• add chain_id required property;
• denom_units, display, name and symbol asset object properties are optional;
• add chain_id required property in asset traces section;
• set chain_name property in asset traces section as optional;
• add supply optional property in asset section and base_supply optional property in asset traces section;
• add admin required property for factory asset type in asset section.
