Crypto-blockchain technologies are leveraging the potential of computers and the web for direct political-social innovation. We’re accustomed to three basic templates for system-wide solutions or improvements: 1. an individual “builds a better mousetrap” and starts a company to exploit this competitive advantage; 2. a company invents something that spawns a new industry (the photocopier, the web browser, for example)...

At an MIT book launch in Zurich, David Shrier and Alex Pentland advertized a new book co-edited by them, “New Solutions for Cybersecurity.” Some takeaways from the event: The really dangerous cyber attacks are yet to come. All major governments are directly or indirectly involved. A promising strategy of minimizing risks relies on (i) continuous encryption; (ii) no central storage of data but case by case requests for data; and (iii) log queries to manage/monitor access. The European...

On Alphaville, Kadhim Shubber reports that just a few marketplaces handle the vast majority of illicit drugs-vs.-bitcoin trades. In short, the illicit bitcoin ecosystem is centered around a small number of services that could be subject to scrutiny, regulation and co-option by law enforcement. It’s a wild west, but luckily for the police all the bad guys are hanging out at a single saloon.

The timing just never seems to fall in our favor. If we had had this conversation ten years ago as would have been appropriate, then this evolution might have fell perfectly in our collective laps. Just as the global financial system, really the international, interbank monetary system of the eurodollar, was crashing all around us, the genesis block of the Bitcoin blockchain was hard coded. Within it contained very...

In the FT, Jamie Smyth reports that the Australian Securities Exchange plans to introduce a blockchain based equity clearing and settlement system. ASX will operate the system on a secure private network with known participants. The participants must comply with regulation, according to the ASX, which said its system had nothing to do with blockchain technology deployed by cryptocurrencies such as bitcoin.

An excellent conference organized by the Monetary Law Forum Switzerland focused on blockchain use cases from a central bank perspective. Program, links to slides. I discussed the macroeconomic perspective and argued for “reserves for all.” Some related links: Nivaura and Allen & Overy (backing Nivaura). OTC Swiss Blockchain, by Roman Bischoff.

Earlier this summer, Tezos smashed existing sales records in the white-hot IPO market after the company’s pitch to build a better blockchain for cryptocurrencies made it one of the buzziest ICOs in the world. As we noted at the time, the company capitalized on that buzz by courting VC firms and other institutional investors with a $50 million token pre-sale. After the company opened up selling to the broader public,...

In an NBER working paper and a column on VoxEU, Michael Bordo and Andrew Levin make the case for central bank issued digital currency (CBDC). Bordo and Levin favor an account-based CBDC system (managed or supervised by the central bank) rather than central bank issued tokens in the blockchain. They emphasize the Friedman rule and the fact that interest paying CBDC affords the possibility to satisfy the rule: These … goals – … a stable unit of account and an efficient medium of exchange –...

The Economist on “initial coin offerings:” Many ICOs are designed to finance applications that will make use of the blockchain … In some cases, the “coins” can be exchanged for services on the site. In a way, this is like selling air miles in a startup airline; investors can either use the miles for flights or hope they can trade them at a profit. For the business, it is also a way of creating demand for the product they are selling. But in plenty of cases, an ICO is just a way of raising...

On bankunderground, Simon Scorer reminds us that a central bank issued digital currency (CBDC) need not operate on a distributed ledger platform. The two do not have much to do with each other. Scorer suggests a series of technical requirements for a CBDC: And he concludes that a distributed ledger does not meet all requirements. It’s unlikely that all of the above attributes could be perfectly met with today’s technology; you may need to make compromises between features – e.g. the...
