The Cognition Open Chain Protocol (COCP) introduces an abstraction layer between applications and heterogeneous blockchain networks. Instead of requiring developers to run and maintain a full node for every chain they integrate with, COCP provides a unified GraphQL-based API that normalizes access to accounts, transactions, and blocks across supported blockchains.

Under the hood this is achieved through Chain Adapters — modular components that translate each chain’s native protocol into standardized API calls. These adapters operate at multiple levels:

  • common chain APIs (basic functions like block and transaction retrieval)

  • common chain data APIs (state queries and account details)

  • native chain APIs

By decoupling blockchain-specific logic from application logic, COCP enables developers to write once and deploy across chains, while preserving access to advanced, chain-specific features when needed. The protocol is extensible: new adapters can be developed and contributed by the community, expanding support for additional blockchains without changing the core API surface.

COCP Console

What is COCP Console?

You can think of it as three things at once:

1

A front-end to the COCP service

The Console is the entry point to everything COCP offers. It gives you a direct way to run queries, explore responses, and get comfortable with the protocol.

2

Real-time, interactive documentation

Because COCP is built on GraphQL, the Console doubles as live documentation. You get a single endpoint, typed queries, and autocomplete inside the editor — just like you’d expect in a modern IDE.

A reference application in the Cognition Network ecosystem

The Console will also be the first working dApp on COCP. It will demonstrate how developers can plug into multi-chain data through one consistent interface.

Getting Set Up

Before diving in, it helps to have a simple mental model of blockchain data:

  • Account: An address plus public/private key pair.

  • Transaction: A transfer between accounts or a smart contract call.

  • Block: A collection of transactions validated through consensus (PoW, PoS, etc.).

COCP’s APIs revolve around these core entities, so once you’re comfortable with them, the queries make sense across different chains.

A bit of GraphQL knowledge is also useful, but the syntax is minimal and the Console makes it easy to learn.

First Query with COCP Console

On release open cocp.cognitionnetworkarrow-up-right. The Console will be split into two panes: query editor on the left, results on the right.

Here’s a simple query to start with:

Run it, and you’ll see Bitcoin’s genesis block returned in JSON. No node setup required.

Expanding the Query

To pull in the transaction details from the genesis block, add more fields:

The output confirms that the block contains a single transaction sending 50 BTC to 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa.

Beyond Raw Data

The Console isn’t limited to JSON responses. It also provides:

  • Table View: Formats values in human-readable units, and links out to block explorers.

  • Chart View: Lets you visualize activity — like a Sankey diagram showing transaction flows.

Multi-Chain Queries

One of the strengths of COCP is unified support for multiple chains. In the Console, you can switch between Ethereum, Bitcoin, Solana and others directly from the dropdown.

The query surface is nearly identical across chains. Supported queries include:

  • blockByHeight / blockByHash

  • transactionByHash

  • transactionsByAddress

  • accountByAddress

  • transactionsByToken (for Ethereum tokens)

This consistency saves time and avoids the overhead of learning a new API for every chain.

Closing Thoughts

The COCP Console makes it simple to experiment with multi-chain data. Instead of managing nodes and juggling APIs, you can query blockchain data directly, visualize it, and start building.

If you run into issues on release, COCP logs errors on both the back end and front end, and the team will work quickly to resolve them.

We hope upon release you will take a few minutes to try it — you’ll see how much easier blockchain development becomes when data access is unified.
