Architecture

Architecture Overview of XSPACE Protocol

The XSPACE Protocol architecture is designed to deliver a highly scalable, secure, and interoperable blockchain ecosystem. By integrating a sharded architecture, an advanced Delegated Proof-of-Stake 2.0 (DPoS 2.0) consensus mechanism, and cross-chain bridges, XSPACE achieves the necessary performance to support real-world asset (RWA) tokenization, decentralized finance (DeFi), and smart city integrations.

Blockchain Design and Consensus

Delegated Proof-of-Stake 2.0 (DPoS 2.0)

DPoS 2.0 is a next-generation consensus mechanism that balances scalability, decentralization, and energy efficiency.

Key Features:

1. Dynamic Validator Rotation:

   • Validators are selected from a pool of candidates based on their stake, performance, and community votes.

   • Validators are dynamically rotated to prevent centralization and promote fairness.

2. Byzantine Fault Tolerance (BFT):

   • DPoS 2.0 incorporates BFT algorithms to ensure that the network remains operational even if up to 33% of validators are malicious.

3. Instant Finality:

   • Transactions achieve finality within 1-2 seconds, making XSPACE suitable for high-speed financial applications.

4. Energy Efficiency:

   • Unlike Proof-of-Work (PoW), DPoS 2.0 significantly reduces energy consumption, making it an eco-friendly choice.

Process Flow:

1. Delegation:

   • Token holders delegate their GLXYC tokens to validators to participate indirectly in securing the network.

   • Delegators earn a share of the staking rewards generated by validators.

2. Validation and Block Production:

   • Validators create and validate blocks.

   • Selected validators rotate regularly, ensuring decentralization and fairness.

3. Rewards Distribution:

   • Staking rewards are distributed proportionally to validators and delegators based on their stake and uptime.

Sharded Architecture

XSPACE employs a sharded architecture to divide the blockchain into smaller, independent units (shards) that process transactions in parallel.

Key Features:

1. Parallel Transaction Processing:

   • Each shard operates independently, handling a subset of transactions, smart contracts, and data storage.

   • The Beacon Chain coordinates cross-shard communication, ensuring consistency across the network.

2. Dynamic Sharding:

   • Resources are dynamically allocated to shards based on network demand.

   • Example: During high traffic on a DeFi application, its shard can be allocated more computational power.

3. Scalable Throughput:

   • Initial throughput of 20,000+ transactions per second (TPS) in early phases.

   • Scales to 50,000+ TPS as additional shards are added to the network.

4. Fault Isolation:

   • Issues within a single shard (e.g., congestion) do not affect the performance of other shards.

How Sharding Works in XSPACE:

1. Transaction Assignment:

   • Transactions are assigned to specific shards based on their account address or smart contract ID.

2. Beacon Chain Coordination:

   • The Beacon Chain synchronizes shard data, ensuring global consistency and resolving inter-shard transactions.

3. Cross-Shard Communication:

   • Transactions spanning multiple shards (e.g., token transfers) are processed seamlessly through efficient cross-shard protocols.

Scalability Features

Scalability is critical for XSPACE, given its mission to support high-throughput applications like tokenized asset trading, smart city services, and DeFi platforms.

1. Dynamic Resource Allocation

• The network dynamically allocates computational resources to shards experiencing high traffic.

• This prevents bottlenecks and ensures consistent performance during peak usage.

2. Layered Architecture

• Layer 1: Core blockchain layer that handles sharding, consensus, and transaction validation.

• Layer 2: Off-chain computation and scaling solutions for specific use cases like microtransactions and gaming.

3. Efficient Data Storage

• On-chain data is optimized using data pruning and compression techniques, reducing storage requirements without compromising transparency.

• Example: Tokenized real estate assets store key ownership metadata on-chain, while detailed asset information resides off-chain (e.g., IPFS).

4. zk-SNARKs for Lightweight Proofs

• zk-SNARKs enable verification of transactions and states without transferring large amounts of data, improving speed and privacy.

Cross-Chain Interoperability

Cross-chain interoperability allows XSPACE to connect seamlessly with other blockchain ecosystems, enabling tokenized assets and GLXYC to flow freely across networks.

1. Cross-Chain Bridges

XSPACE bridges connect it to major blockchain ecosystems like Ethereum, Solana, Binance Smart Chain, and Polygon.

Features:

1. Asset Transfers:

   • Tokenized assets created on XSPACE can be transferred to external chains for trading or liquidity provisioning.

   • Example: Transfer a tokenized real estate asset from XSPACE to Ethereum for trading on Uniswap.

2. GLXYC Liquidity:

   • GLXYC tokens can be bridged to external ecosystems, increasing liquidity and adoption.

3. Two-Way Compatibility:

   • XSPACE bridges support both inbound and outbound transfers, ensuring seamless integration with other platforms.

Bridge Workflow:

1. Locking Assets:

   • Assets are locked on the source chain.

2. Minting Wrappers:

   • Corresponding wrapped assets are minted on the destination chain (e.g., GLXYC-ETH on Ethereum).

3. Burning and Unlocking:

   • When assets move back, wrapped tokens are burned, and the original tokens are unlocked.

2. Cross-Network Liquidity

XSPACE supports multi-chain liquidity pools, enabling tokenized assets and GLXYC to participate in DeFi applications across chains.

Example Use Cases:

1. Tokenized Real Estate:

   • Fractional ownership tokens for a property on XSPACE can be used as collateral in Ethereum-based DeFi platforms.

2. Cross-Chain Governance:

   • XSPACE DAOs can incorporate votes and token holders from other blockchains.

3. Interoperable Standards

XSPACE follows interoperable standards to ensure smooth integration with external chains:

• ERC-20 Compatibility: GLXYC tokens can be bridged as ERC-20 tokens on Ethereum.

• ERC-721/1155 for NFTs: Tokenized assets can be traded on NFT marketplaces like OpenSea.
