Method for data sharing between virtual asset service providers across a secure communication channel

A method comprising:

• during a first time period:
• accessing a first set of policies implemented by a first entity;
• accessing a second set of policies implemented by a second entity;
• identifying the second entity as a candidate counterparty to the first entity based on correspondence between the first set of policies and the second set of policies;
• generating a first notification specifying the second set of policies;
• transmitting the first notification to the first entity;
• generating a second notification specifying the first set of policies;
• transmitting the second notification to the second entity;
• receiving a first confirmation indicating the second entity as trusted by the first entity based on the second set of policies;
• receiving a second confirmation indicating the first entity as trusted by the second entity based on the first set of policies;
• and
• generating a communication channel between the first entity and the second entity in response to receiving the first confirmation and the second confirmation;
• and
• during a second time period:
• receiving a transaction request from the first entity, the transaction request:
• representing a transfer of a virtual asset from a first blockchain address associated with a first user identifier to a second blockchain address;
• and
• confirming absence of the first user identifier from a list of sanctioned user identifiers;
• identifying the second entity as associated with the transaction request in response to:
• associating the second blockchain address with the second entity during the first time period;
• and
• the transaction request specifying the second blockchain address;
• generating a message representing the transaction request;
• transmitting the message to the second entity via the communication channel;
• receiving a transaction rejection from the second entity, the transaction rejection indicating rejection of the transfer of the virtual asset by the second entity based on presence of a second user identifier, associated with the second blockchain address, in the list of sanctioned user identifiers;
• and
• transmitting the transaction rejection to the first entity via the communication channel.

A method comprising:

• during a first time period:
• receiving a first set of policies implemented by a first virtual asset service provider;
• receiving a second set of policies implemented by a second virtual asset service provider;
• identifying the second virtual asset service provider as a candidate counterparty to the first virtual asset service provider based on correspondence between the first set of policies and the second set of policies;
• granting access of the second set of policies to the first virtual asset service provider;
• granting access of the first set of policies to the second virtual asset service provider;
• receiving a first confirmation indicating the second virtual asset service provider as trusted by the first virtual asset service provider based on the second set of policies;
• receiving a second confirmation indicating the first virtual asset service provider as trusted by the second virtual asset service provider based on the first set of policies;
• and
• generating a communication channel between the first virtual asset service provider and the second virtual asset service provider in response to receiving the first confirmation and the second confirmation;
• and
• during a second time period:
• receiving a transaction request from the first virtual asset service provider, the transaction request:
• representing a transfer of a virtual asset from a first blockchain address associated with a first user identifier to a second blockchain address;
• and
• confirming absence of the first user identifier from a list of sanctioned user identifiers;
• identifying the second virtual asset service provider as associated with the transaction request in response to:
• associating the second blockchain address with the second virtual asset service provider during the first time period;
• and
• the transaction request specifying the second blockchain address;
• generating a first message based on the transaction request;
• transmitting the first message to the second virtual asset service provider via the communication channel;
• receiving a transaction authorization from the second virtual asset service provider, the transaction authorization:
• indicating acceptance of the transfer of the virtual asset by the second. virtual asset service provider based on absence of the first user identifier from the list of sanctioned user identifiers;
• and
• confirming absence of a second user identifier, associated with the second blockchain address, from the list of sanctioned user identifiers;
• generating a second message based on the transaction authorization;
• and
• transmitting the second message to the first virtual asset service provider via the communication channel.
