Block8's Chief Technology Officer16.06.2020.
Block8's mission is to use distributed ledgers to make a fairer and more efficient world.
We selected the word “Fairer” because this technology is, fundamentally, a new tool in our ability to organise information. In particular, Distributed Ledger Technology (DLT) provides the ability to reliably share - decentralise - information relating to things of value (digital representations of 'rivalrous' assets), meaning that market power no longer needs to be centralised, and parasitic information asymmetries can be minimised.
We selected the word “Efficient” because a distributed ledger is a modern invention that seeks to optimise a very old yet very common use case: intermediation. Distributed ledgers solve intermediation with technology - a set of use cases that have previously enjoyed no technological innovation since the invention of the original solution: custody. Where custody is not used to facilitate a transaction between two untrusting entities, additional processes are needed to ensure each entity is satisfied with the integrity and outcome of the transaction. Hence, with a distributed ledger, the time and cost efficiency of any transaction is improved when there is an agreed source of truth (data) for that transaction process between the entities, and now, when designing information systems that facilitate interactions between entities, we have a second technology option: a distributed system.
With today’s hyper-centralised information technology mix, the biggest efficiencies we observe are from the biggest centralised services. Under these centralised models, there is usually little scope for more than a single software platform (market) in any given domain; think the social network, the professional network, the market for ridesharing, or the market for short term holiday rentals.
But the centralisation of information causes the centralisation of power and the introduction of market information asymmetry. This precarious situation often leads to negative side-effects, such as data misuse (abuse) and mismanagement (breach).
Centralised Information Systems
With the advent of secure decentralised systems (blockchain, DLT), we have collectively begun to challenge the status quo of the use of centralised systems for delivering shared processes and information, particularly when that information is commercially valuable or in the public interest to be made public.
Fundamentally, centralised systems are closed, meaning that access is only provisioned via the central authority, and then only a ‘view’ of the central source of truth is provided via a digital interface (APIs); the central source of truth is never truly seen. This causes several issues:
Decentralised Information Systems
Per the above, centralised systems - by definition - create data silos, causing costly process friction, and are functionally constrained, limiting innovation. This naturally frames an argument for blockchains:
The possibilities for innovation are quite promising now that we are presented with an alternative paradigm offering the following features over centralised systems:
Download our Response to Treasury to see illustrations of these concepts contrasting “CDR 1.O” - implemented today using APIs - and our vision for “CDR 2.0”: that which can be implemented with DLT today and deliver superior outcomes.
Block8 would be happy to further discuss our thinking on any of the topics covered above, including specific detail on solution architectures and demonstrations of currently working distributed ledger systems developed to address the challenges and opportunities outlined in the Issues Paper and our Response.
Our experts are also available to assist with research mapping the value chains for centralised and decentralised approaches, the identification of the highest-value areas for a consumer-centric data infrastructure, or working with the Government and other members of industry in the development of pilot programs.
 The word ‘intermediation’ here is used in a pure sense. It does not imply “intermediary”. Managing intermediation may necessitate a custodial entity, or alternatively additional procedural overhead between the transacting entities.
 In terms of implementation cost and complexity, some of the cost that would ordinarily be expended in developing an API layer for a regular system would be expended within the logic of the smart contract itself.
