+# Namespace for {non-technical name for ecosystem or family of chains}
+
+Qubic is a high-performance Layer 1 blockchain that offers instant finality, feeless transactions, and rapid smart contract execution.
+It distinguishes itself by integrating Useful Proof of Work (UPoW), transforming mining energy into artificial intelligence computations, thereby laying the groundwork for decentralized Artificial General Intelligence (AGI).
+
+## Governance
+
+Qubic uses a quorum-based consensus system with 676 Computors (nodes) responsible for executing smart contracts, validating transactions, and securing the network. At least 451 Computors must agree to reach consensus, following a Byzantine Fault Tolerance (BFT) model that ensures resilience against malicious or faulty nodes.
+
+Governance applies specifically to changes in the node software and protocol, including updates to consensus rules, computation mechanisms, and economic adjustments. Governance does not directly cover RPC methods, addressability, or multichain compatibility, but protocol modifications may indirectly influence them.
+
+Proposed changes are discussed in the Computors-Operator channel on Discord, where Computors debate modifications before each epoch. An epoch occurs weekly, and approved changes are implemented at the start of the next epoch, ensuring structured and continuous updates to the network.
+
+Developers and Computors can follow governance discussions and decisions on Discord. You can find the invite link to Discord on the [Qubic Official Website][1].

+# CAIP-2
+
+This document is about the details of the Qubic network namespace and reference for CAIP-2.
+
+## Abstract
+
+In [CAIP-2], a general blockchain identification scheme is defined.
+This is the implementation of CAIP-2 for Qubic network.
+
+## Specification
+
+### Namespace
+
+The namespace "qubic" refers to the wider Qubic ecosystem.
+
+### Reference Definition
+
+The reference for the Qubic mainnet is defined as follows:
+
+- `qubic:mainnet`
+
+### Testnet Consideration
+
+As of the creation date of this document, the Qubic blockchain operates solely on its mainnet.
+Should a testnet be introduced in the future, it will be assigned a distinct reference, such as:
+
+qubic:testnet
+
+## Semantics
+
+- **Namespace (`qubic`)**: Identifies the Qubic blockchain.
+- **Reference (`mainnet`)**: Specifies the primary live network of the Qubic blockchain.
+
+## Syntax
+
+The blockchain identifier for Qubic adheres to the following syntax:
+
+qubic:mainnet
+
+This identifier is case-sensitive and must be used exactly as specified.
+
+## Resolution Mechanics
+
+To resolve and interact with the Qubic blockchain using this identifier, clients should direct their requests to the official Qubic RPC endpoint:
+
+https://rpc.qubic.org
+
+This endpoint provides access to network statistics, smart contract interactions, and other blockchain-related data.
+Detailed API documentation is available at [Qubic RPC Documentation][RPC Docs].
+
+## Backwards Compatibility
+
+This is the initial definition of the Qubic namespace under the CAIP-2 standard. 
+There are no previous versions or legacy identifiers associated with this specification.
+
+## Test Cases
+
+To validate the correct implementation of the Qubic blockchain identifier, consider the following examples:
+
+- Valid Identifier: `qubic:mainnet`
+- Invalid Identifier: `Qubic:mainnet` (namespace must be lowercase)
+- Invalid Identifier: `qubic:MAINNET` (reference must be lowercase)
+- Invalid Identifier: `qubic:` (reference is required)
+
+## Additional Considerations
+
+Future updates to the Qubic network, such as the introduction of additional networks (e.g., testnets), will necessitate corresponding updates to this specification to include new references.
