Abstract

Claims (38)

1 . An autonomous system that implements real-time and dynamic account agreements, the autonomous system comprising:

a distributed ledger comprising a plurality of nodes;

a dynamic non-fungible token (“NFT”) stored on the distributed ledger, the dynamic NFT comprising:

a non-editable account number;

a first editable data field;

a second editable data field; and

a third editable data field;

a static NFT stored on the distributed ledger, the static NFT defining operating conditions for an account associated with the non-editable account number;

a digital wallet that issues digitally signed instructions stored on the distributed ledger;

an oracle node on the distributed ledger that provides access to a data feed that is sourced from outside the distributed ledger; and

a smart contract running on the distributed ledger that:

detects digitally signed instructions recorded on the distributed ledger, and in response:

accesses the data feed via the oracle node;

based on the data feed, triggers execution of an action responsive to the digitally signed instructions, wherein the action transfers conditional ownership of the dynamic NFT to a second digital wallet; and

after confirming successful execution of the action, changes the third editable data field to reflect execution of the action;

detects a change in a first value stored in the first editable data field, and in response:

locates the operating conditions stored in the static NFT;

determines, based on the operating conditions, how the change in the first value affects a second value stored in the second editable data field; and

updates the second editable data field in real-time; and

detects a change in the second value stored in the second editable data field, and in response:

locates the operating conditions stored in the static NFT;

determines how the change affects the first value stored in the first editable data field of the dynamic NFT; and

updates the first editable data field in real-time.

2 . The autonomous system of claim 1 , wherein:

the digital wallet is a first digital wallet;

the action is a first action; and

the first action authorizes a second digital wallet to trigger execution of a second action based on a value stored in the third editable data field of the dynamic NFT.

3 . The autonomous system of claim 1 wherein the smart contract enforces the conditional ownership based on the data feed provided by the oracle node.

4 . The autonomous system of claim 1 wherein the oracle node is a first oracle node and further comprising a second oracle node that based on the change to the third editable data field, changes a data record stored outside of the distributed ledger.

5 . The autonomous system of claim 1 wherein the smart contract assigns initial values to the first and second editable data fields based on the operating conditions stored in the static NFT.

6 . The autonomous system of claim 1 wherein:

the first editable data field represents a current interest rate applied to the account;

the second editable data field represents a current account balance of the account;

the third editable data field represents a current owner of the account; and

the data feed accessed by the oracle node includes account balance and ownership information of a plurality of accounts, including the account, managed by an entity that controls the account.

7 . The autonomous system of claim 3 wherein the enforcement comprises:

monitoring the data feed for information relating to a condition of the conditional ownership; and

in response to detecting that the condition is not satisfied, reversing the transfer of conditional ownership.
