Claims:

1. A method of identifying a target transaction on a blockchain comprising the steps: using a search path to identify the target transaction, the search path comprising:

i) a root transaction index (RTindex) comprising a public key (RTPK) associated with the root transaction and an ID (RTID) associated with the root transaction; and ii) at least one attribute associated with the root transaction and/or the target

transaction.

2. A method according to claim 1 wherein:

the at least one attribute is null.

3. A method according to claim 1 or 2 wherein:

the root transaction index (RTindex) comprises:

a hash of a function of the public key (RTPK) and the ID (RTID)

4. A method according to claim 3 wherein the function is a concatenation.

5. A method according to any preceding claim, wherein:

at least one of the attributes is a mnemonic associated with the root transaction or the target transaction.

6. A method according to any preceding claim, wherein:

the root transaction and/or the target transaction comprises a protocol flag.

7. A method according to claim 6, and further comprising the step of:

using a block explorer to identify, in the blockchain, at least one transaction which comprises the protocol flag.

8. A method according to claim 6 or 7, and further comprising the step of:

identifying, in the blockchain, at least one transaction which comprises the protocol flag and storing data related to the at least one transaction in an off-blockchain resource.

9. A method according to claim 8, wherein:

The data related to the at least one transaction comprises:

at least one index associated with the transaction;

at least one index associated with another transaction which is linked to the transaction; and/or

10. A method according to any preceding claim, and further comprising the step of:

accessing a portion of data stored in, or referenced from, the target transaction.

11. A method according to any preceding claim, wherein:

public key (RTPK) associated with the root transaction comprises a human- readable prefix.

12. A computer-implemented system comprising:

a processor; and

memory including executable instructions that, as a result of execution by the

processor, causes the system to perform any embodiment of the computer- implemented method as claimed in any of claims 1 to 11.

13. A non- transitory computer-readable storage medium having stored thereon executable instructions that, as a result of being executed by a processor of a computer system, cause the computer system to at least perform an embodiment of the method as claimed in any of claims 1 to 11.
