What Is A Distributed Ledger And Why It Matters In Business?

A distributed ledger is a ledger that contains a copy of the ledger of all the transactions that are to take place in a shared, virtual database. The main difference between traditional ledgers and DLT is the fact that a distributed ledger uses many participants in a distributed network to process the ledger.

Why Is A Distributed Ledger So Important In Business?

The replicated ledger eliminates the need for a central authority to keep track of the transactions, thus making the creation of digital currencies more accessible. How is DLT used in the crypto economy? Distributed ledger technology is used in cryptocurrencies such as bitcoin. DLT is used to maintain a database of all the transactions that are going on in a market and allow them to be seen simultaneously by all participants.

DLT and its uses

DLT has some major advantages over traditional financial systems.

These include:

  • Safety of transactions Transparency of all transactions
  • Speed and certainty of all transactions
  • Cost of transactions
  • Availability of fast payments

Distributed ledgers gained attention and increased in popularity as they found their application as the core underlying technology of Bitcoin.

The development of the first decentralised application (DApp) by the Ethereum Blockchain is what helped popularise the technology and made it popular within the wider fintech sector.

Ethereum is a cryptocurrency currently ranking at number two in market capitalization after Bitcoin, which is at the top. However, in terms of being used actively, Ethereum is ahead of Bitcoin. While Bitcoin is sent, received, and held only in a singular form, Ethereum allows entities to create different ledgers. These can even be used to create additional cryptocurrencies. The use and transactions using Ethereum have grown consistently over the years ever since it began operations half a decade ago.
decentralized-finance-defi
Decentralized finance (DeFi) refers to an ecosystem of financial products that do not rely on traditional financial intermediaries such as banks and exchanges. Central to the success of decentralized finance is smart contracts, which are deployed on Ethereum (contracts that two parties can deploy without an intermediary). DeFi also gave rise to dApps (decentralized apps), giving developers the ability to build applications on top of the Ethereum blockchain.
smart-contracts
Smart contracts are protocols designed to facilitate, verify, or enforce digital contracts without the need for a credible third party. These contracts work on an “if/when-then” principle and have some similarities to modern escrow services but without a third party involved in guaranteeing the transaction. Instead, it uses blockchain technology to verify the information and increase trust between the transaction participants.
non-fungible-tokens
Non-fungible tokens (NFTs) are cryptographic tokens that represent something unique. Non-fungible assets are those that are not mutually interchangeable. Non-fungible tokens contain identifying information that makes them unique. Unlike Bitcoin – which has a supply of 21 million identical coins – they cannot be exchanged like for like.

What commercial applications did distributed ledgers find so far?

bitcoin
Bitcoin was the first digitalized and decentralized cryptocurrency, released as open-source software in 2009. It uses an underlying technology called Blockchain, which works as digital, distributed ledger, that can be used as a mechanism for disintermediating trust in transactions.  

Distributed Ledger is the underlying technology for Bitcoin, one of the first distributed ledger systems with a wide commercial application.

The biggest benefit of DLT is the fact that the information recorded can be updated by multiple parties independently without any administration on their part.

The process is a peer to peer, allowing transactions to be sent to multiple participants and updating each transaction at the same time. The distributed ledger technology in itself has the ability to track money transfers, manage the transfer of assets, and monitor access to payment services.

As the adoption of DLT increases, it has the potential to transform the way transactions are recorded.

Connected Business Concepts

blockchain-economics
According to Joel Monegro, a former analyst at USV (a venture capital firm) the blockchain implies value creation in its protocols. Where the web has allowed the value to be captured at the applications layer (take Facebook, Twitter, Google, and many others). In a Blockchain Economy, this value might be captured by the protocols at the base of the blockchain (for instance Bitcoin and Ethereum). However, according to blockchain investor Paivinen due to ease of forking, incentives to compete and improved interoperability and interchangeability also in a blockchain-based economy, protocols might get thinner. Although the marginal value of scale might be lower compared to a web-based economy, where massive scale created an economic advantage. The success of the Blockchain will depend on its commercial viability!
proof-of-stake
A Proof of Stake (PoS) is a form of consensus algorithm used to achieve agreement across a distributed network. As such it is, together with Proof of Work, among the key consensus algorithms for Blockchain protocols (like the Ethereum’s Casper protocol). Proof of Stake has the advantage of security, reduced risk of centralization, and energy efficiency.
proof-of-work
A Proof of Work is a form of consensus algorithm used to achieve agreement across a distributed network. In a Proof of Work, miners compete to complete transactions on the network, by commuting hard mathematical problems (i.e. hashes functions) and as a result they get rewarded in coins.
vbde-framework
A Blockchain Business Model according to the FourWeekMBA framework is made of four main components: Value Model (Core Philosophy, Core Values and Value Propositions for the key stakeholders), Blockchain Model (Protocol Rules, Network Shape and Applications Layer/Ecosystem), Distribution Model (the key channels amplifying the protocol and its communities), and the Economic Model (the dynamics/incentives through which protocol players make money). Those elements coming together can serve as the basis to build and analyze a solid Blockchain Business Model.
ethereum-blockchain
Ethereum was launched in 2015 with its cryptocurrency, Ether, as an open-source, blockchain-based, decentralized platform software. Smart contracts are enabled, and Distributed Applications (dApps) get built without downtime or third-party disturbance. It also helps developers build and publish applications as it is also a programming language running on a blockchain.
the-graph-token
The Graph is an ERC20 Utility Token (built on top of Ethereum) to enable consumers to freely query the blockchain through a fully decentralized database kept by indexers, incentivized by the payment of tokens (called GRT). The network is also ministered by curators and delegators that help maintain a high-quality index.
bat-token
BAT or Basic Attention Token is a utility token aiming to provide privacy-based web tools for advertisers and users to monetize attention on the web in a decentralized way via Blockchain-based technologies. Therefore, the BAT ecosystem moves around a browser (Brave), a privacy-based search engine (Brave Search), and a utility token (BAT). Users can opt-in to advertising, thus making money based on their attention to ads as they browse the web.
ripple-blockchain
In 2012, co-founders Christian Larsen and Jed McCaleb created Ripple, a technology acting as both a pre-mined cryptocurrency called XRP and a digital payment platform enabling monetary transactions. Where Ripple is the tech company, XRP is the decentralized ledger.
stellar-blockchain
In 2014, Jed McCaleb – which also played a key role in the development of Ripple – created a cryptocurrency to provide fast, reliable, and affordable money transactions. The same cryptocurrency has considerably grown seven years later. It is now one of the most stellar cryptocurrencies to provide a real-time platform that links banks, payment systems, and people. Meet, Stellar!
bittorrent-token
In early 2019, a joint project between TRON and BitTorrent Foundation called BitTorrent Token came to fruition. BitTorrent Token launched to tokenize in-demand file-sharing protocol and enhance content delivery and bandwidth accessibility with blockchain technology.
