What is DLT? Distributed Ledger Technology Explained

R3 Corda crossed over $10 billion in tokenized real-world assets across its live networks as of February 13, 2025, processing over 1 million transactions per day. And the platform does not use a blockchain. That gap, between distributed ledger technology as a category and blockchain as one of its implementations, is the single most useful idea on this page.

Distributed ledger technology (DLT) is a system in which protocols and supporting infrastructure allow computers in different locations to propose and validate transactions and update records in a synchronized way across a network, per the Bank for International Settlements. Blockchain is one type of DLT, not the whole category.

Key Takeaways

• Distributed ledger technology is a shared, synchronized record of transactions across many computers without a central administrator, according to the Bank for International Settlements.
• Blockchain is one data structure used inside some distributed ledgers, not a synonym for DLT, per World Bank FinTech Note No. 1.
• The Swiss National Bank ran the world’s first live monetary policy operation on DLT infrastructure in June 2024 under Project Helvetia III.
• BIS Project Agora brings together seven central banks and over 40 institutional crypto adoption, testing a multi-currency unified ledger for wholesale cross-border payments.
• R3 Corda carried over $10 billion in on-chain real-world assets across live networks as of February 2025, with more than 1 million daily transactions.
• Linux Foundation Decentralized Trust launched in September 2024 with 100+ founding members and 17 projects, absorbing the Hyperledger ecosystem.

How Does Distributed Ledger Technology Work?

Distributed ledger technology works by keeping identical copies of a transaction record on many computers at once, then using a consensus rule to agree on each new entry. The BIS describes DLT as protocols that allow computers in different locations to propose and validate transactions and update records in a synchronized way across a network. The World Bank defines it as an approach to recording and sharing data across multiple data stores that are collectively maintained by a distributed network of participants. Think of it as a shared spreadsheet that every bank in a consortium holds a live copy of, where new rows can only be added after a supermajority agrees the entry is valid.

1. Multiple Synchronized Copies of the Ledger

Every participating node stores the same ledger. There is no master server. If one node fails or is attacked, the others keep running, which is why the World Bank notes that removing the central party also removes the single point of attack in the network. Traditional distributed databases still rely on a system administrator to maintain a master copy, but DLT replaces that administrator with cryptography and consensus.

2. Consensus Validates New Entries

Before a new transaction becomes part of the record, the nodes run a consensus procedure. Bitcoin maintains its distributed database in a decentralized way by using a consensus-based validation procedure and cryptographic signatures, per the BIS. Different networks use different consensus rules, from proof-of-work and proof-of-stake on public chains to the voting and notary systems used by permissioned enterprise platforms.

3. Cryptography Locks the Record

Each entry is signed with a private key and chained to the previous state using cryptographic hashes. Tampering with any earlier record breaks the chain of hashes, so blockchains use cryptographic and algorithmic methods to record and synchronize data across a network in an immutable manner, according to the World Bank.

4. The Data Structure Varies (Blockchain vs Notary vs DAG)

This is where most definitions collapse. The BIS explicitly notes that current wholesale DLT payment applications have abandoned standard blockchain technology in favour of protocols that modify the consensus process for confidentiality and scalability, with Corda replacing blockchain with a notary architecture. So a ledger can be distributed without being a blockchain.

Data Structure	How It Orders Transactions	Example Network
Blockchain	Transactions grouped into connected blocks	Bitcoin, Ethereum
Notary architecture	Consensus reached per transaction, not per block	R3 Corda
Permissioned blockchain	Blocks with controlled validator set	Hyperledger Fabric
DAG (directed acyclic graph)	Transactions reference multiple predecessors	Hedera (Hashgraph)

Why Does Distributed Ledger Technology Matter?

DLT matters because regulated financial institutions have already moved from concept to production. The Swiss National Bank became the world’s first central bank to conduct a live monetary policy operation on DLT infrastructure in June 2024, issuing digital SNB Bills under Project Helvetia III that were settled in wholesale central bank digital currency. The BIS followed with a multi-jurisdiction programme. Project Agora brings together seven central banks, including those of five major reserve currencies, and over 40 leading financial institutions to test a multi-currency unified ledger for wholesale cross-border payments.

Commercial adoption has moved in lockstep. R3 Corda reached $10 billion in on-chain real-world assets across live networks in February 2025, with over 1 million transactions processed each day, and the RWA market has expanded by 80% over the past two years, with Standard Chartered estimating that demand for tokenized RWAs could reach $30.1tn by 2034. Our coverage of central bank DLT pilots shows a consistent cadence: from first public concept to live production inside 18 months, matching the timing we have tracked across payment rail rollouts.

DLT vs Blockchain: The Critical Distinction

Blockchain is a subset of DLT, not a synonym. The World Bank states that a blockchain is a particular type of data structure used in some distributed ledgers, which stores and transmits data in packages called blocks that are connected in a digital chain. Distributed ledgers themselves are a specific implementation of the broader category of shared ledgers, per World Bank FinTech Note No. 1. So the nesting reads: shared ledger > distributed ledger > blockchain.

Concept	Definition	Example
Shared ledger	Any record of data shared across parties	Bank-to-bank reconciliation file
Distributed ledger	Shared ledger maintained by a decentralised network with consensus	R3 Corda, Hyperledger Fabric, Bitcoin
Blockchain	A distributed ledger that batches transactions into cryptographically linked blocks	Bitcoin, Ethereum

Source: World Bank FinTech Note No. 1, Bank for International Settlements

Key finding: According to the Bank for International Settlements, Corda replaces blockchain with a “notary” architecture and allows consensus to be reached on an individual transaction basis, rather than in blocks, with limited information-sharing. This is why the largest live enterprise DLT network in regulated finance deliberately chooses not to use a blockchain.

Pros, Cons, and Risks of Distributed Ledger Technology

Advantages

• No central point of attack. Because the ledger is replicated, the World Bank notes that security is enhanced because there is no longer a single point of attack in the entire network.
• Peer-to-peer validation without a trusted central party. The World Bank highlights that self-interested participants in a P2P network can collectively record verified data in a shared ledger without relying on a trusted central party.
• Lower reconciliation cost. Removal of the central party can increase speed and remove costs and inefficiencies associated with maintaining traditional systems, per World Bank analysis.
• Atomic settlement and programmability. Tokenized payment platforms can update all accounts at once and embed conditional logic in the ledger.

Trade-offs and Risks

• Proof-of-work is expensive and public. The BIS warns that proof-of-work blockchains are costly to operate, offer only probabilistic finality of settlement, and make all transactions public, which are features not suitable for many financial market applications.
• Operational complexity at go-live. The Swiss National Bank observed that while implementing monetary policy on DLT was feasible and effective, new challenges emerged in the corresponding processes.
• Regulatory coordination. Cross-jurisdictional DLT payment systems must align settlement finality, anti-money-laundering, and CFT rules across every participating country. BIS Project Agora is explicitly scoping those gaps.

Types of Distributed Ledger Technology

DLT networks fall into two broad categories based on who can join as a validator. The split matters because regulated finance almost always uses the permissioned variety, while public cryptocurrencies use the permissionless one.

Type	Who Can Validate	Confidentiality	Example Platforms
Permissionless (public)	Anyone with the software	Transactions public	Bitcoin, Ethereum
Permissioned (enterprise)	Vetted participants only	Configurable, often private	R3 Corda, Hyperledger Fabric, GoQuorum
Hybrid	Mixed public and private nodes	Tiered	SIX Digital Exchange (SDX), some CBDC pilots

Linux Foundation Decentralized Trust, which now hosts the Hyperledger ecosystem, launched on September 16, 2024, with more than 100 founding members and 17 projects. The umbrella organization builds on more than eight years of prior Linux Foundation work and includes 200 local, regional and industry groups in the Hyperledger ecosystem.

Real-World Applications of Distributed Ledger Technology

Cross-Border Payments

Cross-border payments are the use case central banks have pushed hardest. BIS Project Agora combines seven central banks and over 40 financial institutions in a public-private partnership testing a unified ledger, a programmable platform that uses tokenized money to streamline international payments. The goal is to replace the correspondent banking chain, where each leg settles sequentially, with one shared programmable platform.

Tokenized Real-World Assets

Tokenization of real-world assets on DLT has moved from pilot to production. R3 Corda represents the largest ecosystem of live RWA networks by on-chain volume, with over $10 billion in tokenized assets and over 1 million daily transactions as of February 2025. Tokenization of RWAs has become an important goal across the G7 and major markets globally, with 50% of institutional investors expressing specific interest in investing in tokenized assets.

Central Bank Monetary Policy

Central banks have begun executing real policy operations on DLT, not just simulations. Under Project Helvetia III, the Swiss National Bank issued digital SNB Bills in June 2024, settled in wholesale central bank digital currency in a production environment, becoming the first central bank to do so.

Scenario: A Bank-to-Bank Tokenized Bond Settlement on DLT

Here is how a typical production DLT settlement works, based on the public mechanics of the SNB Helvetia III pilot.

• Bank A issues a CHF 10 million bond on the SIX Digital Exchange (SDX), a permissioned DLT platform.
• The bond is represented as a token on the shared ledger, and the issuance details are validated by the network’s notary nodes.
• Bank B agrees to buy the bond and sends a tokenized wholesale CBDC payment to Bank A.
• The DLT executes an atomic swap: the bond token moves to Bank B at the same instant the CBDC token moves to Bank A.
• The Swiss National Bank, which runs a node on the ledger, observes the settlement as final. No manual reconciliation is required, and both banks’ internal books update from the same shared record.

The entire sequence can be completed in minutes. The same trade on legacy T+2 rails would involve multiple custodians, a central securities depository, and correspondent banking, often taking two business days.

Conclusion

Distributed ledger technology is best understood as the category, not the product. The public narrative tends to treat DLT and blockchain as synonyms, yet the largest regulated-finance deployment runs on a notary architecture that the Bank for International Settlements explicitly distinguishes from blockchain. Based on the central bank and enterprise milestones now in production, our editorial view is that the DLT conversation in regulated finance through 2027 will be dominated by permissioned, non-blockchain platforms, with public chains remaining the home of cryptocurrency and a growing slice of retail tokenization rather than wholesale settlement.

For readers tracking adoption numbers, the anchor points are clear: $10 billion in live tokenized assets on Corda, seven central banks testing a unified ledger with the BIS, and one live central bank policy operation already in the books. For crypto investors mapping the ecosystem against wholesale finance, our crypto coverage, DeFi market statistics, and crypto adoption rates by country show where the DLT frontier is moving next.
