T/GXDSL 057-2025 Carbon sink blockchain trading platform construction guideline

Scope

Main technical content: This standard comprehensively stipulates the construction requirements and technical specifications for carbon sink blockchain trading platforms, and is applicable to all types of carbon sink asset registration, trading, and clearing settlement systems based on blockchain technology. In terms of carbon sink types, this standard covers major carbon sink projects such as forestry carbon sinks (carbon storage ≥ 1tCO?e/ha·a), grassland carbon sinks (carbon sequestration ≥ 0.5tCO?e/ha·a), and marine carbon sinks (carbon sequestration ≥ 0.3tCO?e/ha·a), requiring that carbon sink assets be audited and certified by professional institutions (with an error of ≤ ±5%), and comply with relevant national greenhouse gas emission reduction management measures. In terms of technical architecture, this standard specifies the technical requirements for core modules such as the blockchain underlying layer (consensus time ≤ 1s, smart contract execution delay ≤ 100ms), the application service layer (API response time ≤ 200ms), and the data storage layer (query delay ≤ 100ms). The platform must support multi-chain architecture (cross-chain delay ≤ 500ms), have high throughput (≥ 5000 TPS), high concurrency (≥ 10,000 transactions/second), and large-capacity storage (≥ 10PB), ensuring the full life cycle management of carbon sink assets (data retention period ≥ project cycle + 10 years). In terms of functional requirements, the platform should implement core functions such as digital registration of carbon sink assets (onchain time ≤ 30s), market-based trading (matching delay ≤ 100ms), automated clearing and settlement (settlement time ≤ 1min), and intelligent supervision (data reporting delay ≤ 1min). It also supports extended functions such as pledged financing of carbon sink assets (pledged registration time ≤ 1min) and innovative carbon financial derivatives (product registration time ≤ 1 working day), meeting the needs of diversified carbon market development.
