Blockchain: Which Custody for Which Tokens?

13/09/2019

The organization of custody for crypto-currencies or other crypto-assets (also called tokens) must consider certain peculiarities, for example the absence of an issuer identified for crypto-assets or the lack of control of the custody process.

In France, since the dematerialisation of securities in 1984, the ownership of financial securities is recorded by an entry in a securities account, an account that can be held:

  • either by a financial intermediary who is an approved Custody Account Keeper, in which case they are called Bearer securities because the identity of the holders is not communicated to the issuer when these securities are exchanged;

  • or by the issuer of the securities themselves, in which case they are called Registered securities because the issuer knows the investor’s identity. If the investor mandates an intermediary to hold the securities account opened with the issuer, we talk about "Administered Registered Securities", whilst in the absence of intermediation we talk about "Pure Registered Securities".

Whilst the relationship with the issuer is intrinsically facilitated for registered securities, ownership transfer procedures are reputed to be simpler and faster for bearer securities. In all cases, it is the holder of the official securities account (issuer or intermediary) who is legally responsible vis-à-vis the end investor and guarantees the latter’s ability to exercise the rights associated with the securities’ ownership throughout this security’s life cycle. The fact that the investor can freely change account holder means that the latter must be in a position to return the securities to their holder at any time. Of course, no such guarantee can be provided by the custody account keeper unless they have the technical tools to ensure this custody.

The case of crypto-currencies

As these crypto-currencies do not have an issuer, the responsibility for keeping the issuer register is no longer centralized over a single entity but "distributed" in the community of cryptocurrency holders.

The recent French PACTE law passed on 11 April 2019 more or less called this premise into question by attempting to define an “actif numérique” (another name for token) custody service where the service provider is generally not able to control the system that ensures the transfer of these assets’ ownership. Indeed, this system is based on the Blockchain that was originally designed specifically to ensure the transfer of ownership and custody of cryptocurrencies such as Bitcoin or Ether. As these crypto-currencies do not strictly speaking have an issuer, responsibility for issue register keeping is no longer centralised within a single entity but “distributed” across the crypto-currency holder community (validation of operations through a consensus between these holders). That is why this new way of distributing asset custody responsibility ultimately appears to be more of a complement than an alternative to “Bearer” and “Registered” methods, as it targets assets with no issuer that are not covered by these existing methods.

From custody account keeping to position keeping

It would therefore not appear possible for a service provider to assume responsibility for standard custody account keeping for cryptocurrencies on behalf of a third party, as they do not have control of the custody system for these cryptocurrencies. However, they can continue to ensure Position Keeping on these assets, i.e. check that the quantity of cryptocurrencies recognised at Blockchain level complies with the transactions of which they are aware. This position keeping is not a new concept, as it was already proposed in the case of the associated Administered Registered Securities set-up mentioned above. There is, however, a substantial difference between the position keeping of cryptocurrencies and the position keeping of traditional assets (i.e. with an issuer). Indeed in the second case, it is possible for the position keeper to contact the issuer when he feels that the position is non compliant and the discrepancy is not attributable to him. Indeed, for Registered securities the issuer is supposed to have the power to rectify any anomaly concerning their own registers. However, this will no longer be possible with cryptocurrencies, where there is no issuer to contact.

Moreover, ensuring Position Keeping for a third party in a Blockchain obviously requires the holding (and therefore custody) of the means to access the third party’s tokens in this Blockchain, access that can for example be materialised via cryptographic keys.

Il caso di utility o token di sicurezza

Alcune blockchain ambiscono tuttavia a gestire anche asset diversi dalle proprie criptovalute originali, nello specifico Utility Token o Security Token che, nonostante la diversa natura dei diritti connessi (diritti di utilizzo, da una parte, e diritti finanziari, dall’altra), condividono l’esistenza di un emittente reale.

Data la presenza di tali emittenti nella blockchain, è necessario riconoscere loro determinate prerogative sui propri registri che li distinguano dalla comunità di semplici investitori. Pertanto, la distribuzione della responsabilità tra i soli investitori non ha più ragione di esistere e sarà invece opportuno conciliare le blockchain e la modalità Nominativa, come oltretutto previsto dal Codice monetario e finanziario francese all’articolo R211-2. Tuttavia, la distinzione tra modalità Distribuita e Nominativa non è immediata e dovrebbe richiedere sviluppi informatici (smart contract?) e/o specifiche autorizzazioni in base al tipo di blockchain: pubblica (aperta a tutti con 1 solo profilo di partecipanti) o privata (riservata a determinati partecipanti con una possibile differenziazione dei profili).

Standard internazionali

In conclusione, nell’ambito dei token sarebbe più opportuno evitare il termine “Custodia” e parlare di “Tenuta di Posizione” anche se, come abbiamo visto, tale operazione si basa sulla capacità di conservare i mezzi di accesso ai token. Inoltre, dato che la questione supera ampiamente i confini della Francia e il suo quadro normativo, sarebbe indubbiamente auspicabile che gli accorgimenti necessari per tenere conto degli emittenti nelle blockchain siano almeno oggetto di norme a livello europeo e preferibilmente internazionale.
