What Are Distributed Ledgers?
Let me explain what a distributed ledger is: it's a transaction database that's stored and synchronized across multiple sites, institutions, or geographies. You have network nodes that each store copies of the ledger, and they communicate any changes made by users to other nodes, which then update their own ledgers to match. With modern communication technology, these changes can happen in seconds, depending on how quickly nodes compare their states.
Distributed ledgers stand in contrast to centralized ledgers, which businesses and governments commonly use. Centralized ones are more prone to cyber-attacks and fraud because they have a single point of failure, though they do offer security through fewer access points.
Blockchains and directed acyclic graphs are examples of distributed ledgers.
Key Takeaways
Here's what you need to know: a distributed ledger is a transaction database synchronized across different sites and geographies. By using one, you eliminate the need for a central authority to prevent manipulation. These ledgers reduce fraud risk because nodes can be programmed to compare states and reject unverified changes.
Understanding Distributed Ledgers
Data gets collected and entered into digital files, then stored on computers—these files form ledgers. Software lets you access and use this data, granting permissions to those who need it. In the past and often still today, ledgers are stored centrally and controlled by specific users, like on a closed network in a secure room maintained by technicians. Humans audit and verify the data, but they're prone to errors and corruption.
Distributed ledgers follow the same idea of storing data in files, but instead of one main copy on a server with backups, identical copies exist on multiple machines in different locations. These computers, or nodes, automatically update their ledger copies and broadcast states to others. All nodes verify each other's ledgers, keeping the network's database intact.
Most of this involves encryption like hashing data and comparing it, which modern computers and networks handle quickly.
Advantages of Distributed Ledgers
Centralized ledgers are vulnerable to cyber-attacks, but distributed ledgers are harder to compromise because you'd need to alter a majority of copies at once for success. Their distributed setup resists malicious changes by any single party. They also provide more transparency than centralized ones.
This transparency simplifies audit trails for data audits and financial reviews, helping eliminate fraud in company books.
Distributed ledgers cut operational inefficiencies and speed up transactions. They're automated, so they run 24/7. All this lowers costs for those using and operating them.
Distributed Ledger Uses
Distributed ledger technology can revolutionize how governments, institutions, and corporations operate. It helps governments with tax collection, passport issuance, land registries, licenses, Social Security benefits, and voting.
The technology is impacting industries like finance, music and entertainment, diamond and precious assets, artwork, and supply chains for various commodities.
While it has many advantages, distributed ledger technology is still emerging, and we're exploring the best adoption methods. One thing is certain: the future of centuries-old centralized ledgers is decentralization.
What Is the Purpose of a Distributed Ledger?
A distributed ledger prevents data tampering and makes data management more efficient and accurate.
What Is the Difference Between Ledger and Distributed Ledgers?
Distributed ledgers are stored across a wide network and use techniques to compare and validate copies. Centralized ledgers are kept in one location and controlled by an entity.
What Are the Three Types of Distributed Ledgers?
Distributed ledgers are generally categorized as private, public, permissioned, and permissionless. They can be designed as private permissioned, public permissionless, or private permissionless.
The Bottom Line
Distributed ledgers are transaction records stored across a network. Their copies can be programmed to compare and validate data automatically, ensuring accuracy and no alterations. This makes them more reliable than traditional data entry and auditing methods.
