Architectural Overview

HyperGrid's multi-grid architecture overview: semi-autonomous grids anchored to Solana for consensus and finality.

HyperGrid's architecture is predicated on a multi-grid approach, wherein each grid operates semi-autonomously while remaining anchored to the Solana mainnet for consensus and finality. This section will dissect the structural elements and their interrelations.

HyperGrid System Architecture

Key Components

1. Solana Base Layer: The foundation upon which the HyperGrid system is built, providing ultimate consensus and finality.

2. HyperGrid Shared Sequencer Network (HSSN):

   • Central to the architecture, spanning across all grids

   • Contains multiple validators (Validator 1 through Validator N)

   • Facilitates sharing of states between Grids and the Solana Base Layer

   • Manages batch ZK proofs for settlement

3. Grid Structure (exemplified by Grid 1 and Grid 2):

   • Each grid represents a semi-autonomous ecosystem, potentially dedicated to specific applications (e.g., different games)

   • Components within each grid:

     • ZK-Coprocessor: Manages grid-specific operations merkle proof operations.

     • SVM Runtime: Execution environments for Grids on Solana Virtual Machine

     • Sonic Gas Engine: Manages computational resources

     • Concurrent Merkle Tree Generator: Efficiently processes state transitions

4. User Interaction:

   • Users can interact with each grid independently

   • Transactions (SVM Tx and EVM Tx) flow between users and the respective grid's runtimes

   • Transaction responses are sent back to users

Data Flow

1. Interoperability – State Sharing:

   • Bi-directional state sharing occurs between the Solana Base Layer and the HSSN

   • HSSN shares states with individual grids

   • State sharing can also happen between Grids as we shall see later

2. ZK Proofs:

   • Transactions are compressed and aggregated into a Merkle tree.

   • For each block, we shall commit the corresponding root state hash.

   • The Validity Proof for this block is computed on Grid.

   • ZK proofs for settlement are posted from the HSSN to the Solana Base Layer.

This architecture enables HyperGrid to achieve high scalability and flexibility while maintaining a strong connection to the security and finality provided by the Solana blockchain.
