Blockchain: loss of the parties’ control over contracts and the hampered courts

In a blockchain/DLT environment, the parties as well as the competent courts and regulators will lose authority over the enforceability of transactions or smart contracts once they were recorded on the blockchain.

DLT internal governance, discrimination and competition rules

Even though Bitcoin was conceived as a grassroots democracy it cannot live up to this standard – it is entangled in ideological and economic internal conflicts. Similar scenarios might occur insight a blockchain financial network, even if the latter will be permissioned structures.

AML, CTF and KYC in Bitcoin and DLT environments

Beyond the spectacular cases of illegal or illicit use of virtual currencies (see in particular the Silk Road case), concerns about money laundering and terrorist financing surfaced very early on, leading to relevant regulation in New York and intense debate in Europe and elsewhere, including at FATF in Paris. Two characteristics inherent in blockchain technology considerably facilitate illegal activity. However, in the Bitcoin environment this is more of a problem than in any future DLT network set up by regulated entities.

Mitigating systemic risk flowing from blockchain financial systems

The function of blockchain systems used in financial markets might at some future point in time place them among critical infrastructures such as settlement systems and CCPs. Blockchain financial networks would provide a service that would not be easy to replace should they fail to function properly. As networks linking a multitude of financial market actors, potentially of different types, they are also highly interconnected. Hence,, such networks are destined to become important in terms of financial stability once they have attracted a certain volume of assets and a critical number of users. It might therefore be necessary to regulate blockchain financial networks with a view to ensuring that they are resilient and do not contribute to systemic risk but, ideally, help to reduce it.

What makes a ‘Blockchain’ financial network? (III) – Unstoppable execution & smart contracts

In this post, I explore the third fundamental characteristic of blockchain financial (and other) networks: unstoppable execution. This idea is at the same time at the basis of smart contracts. It means that computer code is designed automatically to execute contractual duties upon the occurrence of a trigger event, or, in other terms, the complete excision of human discretion from execution.

What makes a ‘Blockchain’ financial network? (II) – No trust, only maths

A distributed record needs a second (and a third) element to form a blockchain network. This post discusses the necessity of a mechanisms guaranteeing that the updates of records reflect the truth.

From Bitcoin to Blockchain to DLT

The delimitation of what Bitcoin, Blockchain and DLT mean and in what sense they are different and for which purposes they can be used is not always very clear.

What makes a ‘Blockchain’ financial network? (I) – Distributed database and disintermediation

Three characteristics of blockchain technology have the potential of turning our understanding of how the market functions upside down. In this first post of a series of three I discuss the concept of the distributed ledger that lies at the heart of blockchain and the consequential disintermediation of the market, doing away with back office functions and intermediation.
