Classification: CPC H | IPC H

Claim 12:
13. A computer-implemented method, comprising the steps of:
(viii) providing a verification data item (ti) of a one-way function chain of data items;
(ix) providing a data item of the one-way function chain of data items;
(x) applying the one-way function to the data item to verify that ti=H(ti-1) and to provide an output (ti-1);
(xi) comparing the output of step (x) to the data item to provide an outcome; and
(xii) based on the outcome of step (xi):
(a) allocating the output as a further verification data item for verifying a further data item of the one-way function chain of data items; and
(b) granting access to a resource associated with the data item;

(xiii) providing a verification data item of a second one-way function chain of data items;
(xiv) submitting, to a blockchain, an exchange blockchain transaction unlockable upon provision of at least one verification item of the one-way function chain of data items and the verification data item of the second one-way function chain of data items, wherein such unlocking causes at least one data item of the second one-way function chain to be associated with the resource; and
unlocking the exchange blockchain transaction and repeating steps (ix) to (xii) using at least one data item of the second one-way function chain of data items and the verification data item of the second one-way function chain of data items.
