Conflict of laws in blockchain and cryptoassets
I gave a paper on the above theme at a meeting of the Study Group of Private International Law of the Kansai Region (Japan) on 23 January 2021.
Conflict of laws is an abstract subject. So I structured my analysis along typical scenarios which are partially taken from real cases. They include the bankruptcy of an exchange provider, the misappropriation of crypto-assets, the mistaken transfer of crypto-assets, the use of crypto-assets to purchase goods or services, the hacking of a smart contract (or decentralized autonomous organization) and the use of crypto-tokens for securitization. I gave detailed considerations to proprietary issues in particular, as these are a theoretically challenging area. I also gave comments on the works of others including the project of the Hague Conference on Private International Law.
The handout distributed to the audience (in Japanese) is attached here.

Presentation at the conference “UNCITRAL Asia Pacific Day" (4 December 2020 at the University of Macau)
I gave an online presentation on blockchain-based bills of lading under the UNCITRAL Model Law on Electronic Transferable Records in Session III of the conference.
I attach here the slides and the transcript of my presentation as well as the conference timetable. Preparing for this presentation, I built on my Japanese paper given at a symposium in Tokyo one and a half year earlier and published subsequently. This conference was a fitting occasion to convey my thoughts in English and take stock of the latest developments in actual practice.

Dematerialization of Negotiable Instruments
This article considers the legal challenges which will be encountered when blockchains are used to dematerialize negotiable instruments such as bills of lading. The digitization of negotiable instruments yields a lot of benefits to the society but has been hampered by various technological and legal obstacles. On the technological side, this article examines the advantages and drawbacks of the blockchain as a tool for dematerializing negotiable instruments. On the legal side, there is a lot of uncertainty over the permissibility of, and the legal requisites for, dematerializing negotiable instruments. To improve certainty, the UNCITRAL created the Model Law on Electronic Transferable Records in 2017. The Model Law lays down the attributes which an electronic record needs to possess before it is deemed to be functionally equivalent to the corresponding "transferable instrument," a term broadly synonymous with "negotiable instrument." Thus, the electronic record must, by virtue of a reliable method, be identifiable (which implies the consistency of the record) and amenable to exclusive control. This article considers whether blockchain-based electronic records have these attributes. Among such attributes, the reliability of the method poses a particular challenge to the current law since the latter is not accustomed to evaluate the reliability of blockchains. Prior to the emergence of the blockchain technology, electronic records could only be maintained by an administrator of the database. It follows that under the conventional approach, the reliability of the method would be ensured through the regulation and oversight of the administrator. The blockchain, on the other hand, is a trustless technology which is founded on the notion that a system dispensing with the need for administrators is reliable for the very reason that it is distrustful. Whether the law is ready to embrace this notion will be tested if the society is to harness the full potential of the blockchain.
