Distributed Ledger Technologies (or Blockchains) have gained a tremendous amount of traction over the last couple of years or so, and they are due to serve a far larger purpose than anyone could have imagined in the early Bitcoin days. This article aims to explain how distributed ledgers are changing the modern internet as we know it, on a very fundamental level.
Communication protocols like TCP/IP and HTTP were created in the early days of the internet, which were considered (and still are) great technological advances. These early protocols were developed by scientists and researchers without much financing or economic incentive for outperformance or competitiveness. Distributed ledger technologies (DLT) are essentially new P2P versions of communication protocols, with embedded data and even processing capability between systems. These are being developed and used today for various reasons; store of monetary value (such as Bitcoin), processing power (Ethereum), or data storage (StorJ and Siacoin). New DLT’s are being developed continuously, a handful are raising funding at the time of writing this article.
The important thing to understand about DLT’s is that each have their own embedded economic models, creating incentives for different parties in the system to develop, secure, and run the network of peers (or nodes). For example, Bitcoin is considered a store of value, where the Bitcoin holder pays miners to secure the network in the form of inflation. Meanwhile in Ethereum, network users use Ethereum tokens (Ether) to pay for processing power. This means that each token in each DLT’s network has a monetary value, since it can be exchanged for goods or services.
Distributed ledgers provide a new way of storing, maintaining, and accessing data. Rather than storing data on centralized servers, the data is stored across all peers (nodes) in the network, meaning that there’s a correct copy of data stored in “n” amount of locations across the globe, but how does this add any value? Decentralizing data decreases the risk of data loss, as a failure in a single node will only have a marginal impact on the entire network. Perhaps the most important feature of DLT is correctness, making data alterations in a single node will not affect the general consensus across all other nodes.
Traditional internet companies, like Facebook, Google and Twitter, hoard massive amounts of data, and the vast majority of their revenues and market value is based on proprietary data. Now imagine a world where data and processing power is housed within the internet protocol (i.e. Ethereum Virtual Machine), and the internet application is simply a thin layer sitting on top. This means that most of the value lies within the “fat protocol”, while the internet companies themselves capture only a smaller proportion based on what type of user experience they can provide. In this environment, entry barriers to very capital and data intensive industries are far lower, and we can expect a much higher level of competitiveness, better user experience, and general social benefit. The scalability of distributed ledgers is often debated, but in case the underlying technology catches up, we may even see performance related scale advantages in using distributed ledgers.
There is no guarantee that data and processing will move to a distributed environment, but as more and more data is stored on distributed ledgers, the higher the value of utilizing that technology there will be, this “network effect” may lead to exponential growth in adoption of distributed ledgers.
