Computer implemented systems and methods for storing, retrieving and communication data via a peer-to-peer network

A computer-implemented system comprising:

• one or more processors;
• and
• memory including executable instructions that, as a result of execution by the one or more processors, cause the computer-implemented system to at least:
• enable a user to input a query comprising a query keyword to search for, access, view, write and/or retrieve a portion of data provided in or referenced by at least one blockchain transaction (Tx), that comprises:
• i) a protocol flag for a blockchain search protocol;
• ii) a transaction index (TXindex);
• and
• iii) at least one attribute comprising at least one keyword associated with the at least one blockchain transaction;
• send the query to a blockchain search system that is arranged to:
• i) maintain a database of the index and at least one keyword of each blockchain transaction on a blockchain that comprises the protocol flag for the blockchain search protocol;
• and
• ii) check the query keyword against the database and return, to the computer-implemented system, the transaction index (TXindex) of at least one identified blockchain transaction that contains the query keyword;
• and
• use the transaction index (TXindex) of the at least one identified blockchain transaction to identify the at least one blockchain transaction (Tx) on the blockchain and retrieve the portion of data of the at least one blockchain transaction (Tx).
