Distributed Ledger Technology (DLT)
Distributed Ledger Technology (DLT) is a decentralized digital system for recording, sharing, and synchronizing transactions across a network of computers without requiring a central authority. In financial markets, DLT provides a shared, immutable record of transactions and positions that can be accessed by multiple participants while maintaining data integrity and consistency.
Core principles of DLT in financial markets
DLT systems operate on several fundamental principles that make them particularly valuable for financial applications:
- Decentralization: No single entity controls the entire system
- Consensus: Network participants agree on the validity of transactions
- Immutability: Once recorded, transactions cannot be altered
- Transparency: All authorized participants can view the shared ledger

QuestDB is an open-source time-series database optimized for market and heavy industry data. Built from scratch in Java and C++, it offers high-throughput ingestion and fast SQL queries with time-series extensions.
Market structure implications
DLT is transforming traditional market infrastructure by enabling new models for:
The technology reduces counterparty risk by providing real-time visibility into positions and enabling atomic settlement of transactions.
Risk management applications
DLT enhances risk management capabilities through:
- Real-time position monitoring
- Automated collateral management
- Transparent audit trails
- Reduced operational risk
These features are particularly valuable for Regulatory Compliance Automation and reporting requirements.

Performance considerations
When implementing DLT systems, several performance factors must be considered:
- Throughput capacity
- Network latency
- Consensus mechanism efficiency
- Data storage requirements
These factors are especially important for Real-Time Market Data applications.
Future developments
The evolution of DLT in financial markets is driving innovation in:
- Smart Contracts in Market Infrastructure
- Cross-border settlement systems
- Regulatory reporting automation
- Market data distribution
Financial institutions are particularly focused on how DLT can reduce costs and improve efficiency in post-trade processes while maintaining compliance with regulatory requirements.
