X1 Blockchain Overview
A comprehensive guide to the X1 blockchain - a high-performance, Solana-compatible Layer 1.
What is X1?
X1 is a high-performance blockchain designed for decentralized applications and crypto-currencies. Built with Solana compatibility in mind, X1 leverages a unique Proof of Stake consensus mechanism combined with innovative features optimized for speed, security, and scalability.
Developers can use familiar Solana tools and SDKs to build on X1, making migration and cross-chain development seamless. X1 supports the same account model, transaction structure, and program deployment process as Solana.
Key Features
High Throughput
Process up to 50,000 transactions per second with sub-second block times. X1's architecture is optimized for parallel transaction execution.
Low Transaction Costs
Average transaction fees under $0.001, making X1 ideal for high-frequency applications like gaming, micropayments, and DeFi.
Solana Compatible
Use @solana/web3.js, Anchor, and other Solana tools. Programs written for Solana can be deployed on X1 with minimal modifications.
Energy Efficient
Proof of Stake consensus with significantly lower energy consumption compared to Proof of Work chains.
Architecture
Consensus Mechanism
X1 uses a Proof of Stake (PoS) consensus mechanism combined with Tower BFT, similar to Solana's architecture. Validators stake X1 tokens to participate in consensus and earn rewards.
Key Components:
- Proof of History (PoH): Cryptographic clock enabling timestamp verification without waiting for consensus
- Tower BFT: PoH-optimized version of PBFT providing fast finality
- Gulf Stream: Mempool-less transaction forwarding protocol pushing transactions to validators before the next leader
- Sealevel: Parallel smart contract runtime enabling concurrent transaction processing
Account Model
X1 uses an account-based model where all state is stored in accounts. Each account has:
- lamports:Balance in lamports (1 X1 = 1,000,000,000 lamports)
- owner:Program that owns this account and can modify its data
- data:Raw byte array storing account state
- executable:Boolean indicating if this account contains executable program code
Network Statistics
Token Standards
SPL Token Program
X1 uses the SPL Token standard, fully compatible with Solana's token program. This enables:
- Fungible tokens with configurable decimals
- Associated token accounts for simplified UX
- Mint authority and freeze authority controls

NFTs on X1 use the Metaplex Token Metadata standard, enabling:
- Rich metadata with name, symbol, URI
- Creator verification and royalty enforcement
- Collection verification for grouped assets
Developer Tools
X1 is compatible with the entire Solana development ecosystem:
@solana/web3.js
JavaScript SDK for interacting with X1
Anchor Framework
Rust framework for building programs
Solana CLI
Command-line tools for deployment
Wallet Adapters
Connect to Phantom, Solflare, etc.
