Article 36Essential requirements regarding smart contracts for executing data sharing agreements

1. The vendor of an application using smart contracts or, in the absence thereof, the person whose trade, business or profession involves the deployment of smart contracts for others in the context of executing an agreement or part of it, to make data available shall ensure that those smart contracts comply with the following essential requirements of:

(a)

robustness and access control, to ensure that the smart contract has been designed to offer access control mechanisms and a very high degree of robustness to avoid functional errors and to withstand manipulation by third parties;

(b)

safe termination and interruption, to ensure that a mechanism exists to terminate the continued execution of transactions and that the smart contract includes internal functions which can reset or instruct the contract to stop or interrupt the operation, in particular to avoid future accidental executions;

(c)

data archiving and continuity, to ensure, in circumstances in which a smart contract must be terminated or deactivated, there is a possibility to archive the transactional data, smart contract logic and code in order to keep the record of operations performed on the data in the past (auditability);

(d)

access control, to ensure that a smart contract is protected through rigorous access control mechanisms at the governance and smart contract layers; and

(e)

consistency, to ensure consistency with the terms of the data sharing agreement that the smart contract executes.

2. The vendor of a smart contract or, in the absence thereof, the person whose trade, business or profession involves the deployment of smart contracts for others in the context of executing an agreement or part of it, to make data available shall perform a conformity assessment with a view to fulfilling the essential requirements laid down in paragraph 1 and, on the fulfilment of those requirements, issue an EU declaration of conformity.

3. By drawing up the EU declaration of conformity, the vendor of an application using smart contracts or, in the absence thereof, the person whose trade, business or profession involves the deployment of smart contracts for others in the context of executing an agreement or part of it, to make data available shall be responsible for compliance with the essential requirements laid down in paragraph 1.

4. A smart contract that meets the harmonised standards or the relevant parts thereof, the references of which are published in the Official Journal of the European Union, shall be presumed to be in conformity with the essential requirements laid down in paragraph 1 to the extent that those requirements are covered by such harmonised standards or parts thereof.
