System and methods for verifiable computing, communications and data management

Abstract

Abstract The present disclosure is directed towards method and systems for managing data comprising: appending a block to a centralised topic block-chain wherein: the appended block comprises a hash of the preceding block; the appended block is a genesis block; and the genesis block is the first block in a subtopic block-chain relating to an attribute of the topic block-chain, wherein the subtopic block-5 chain provides a parallel and hierarchical record structure of event blocks, whereby: the centralised topic block-chain is used to store topic-level records and serves as the root of the hierarchy; and the subtopic block-chain is used to store topic-level records of events relating to an update of an attribute of a topic provide a verifiable record of the updates to the attribute. 10 Figure 1. 10 20 26 20 06 56 30 J an 2 02 6 2 0 2 6 2 0 2 6 2 0 0 6 5 6 3 0 J a n 1 0 1 / 1 Figure 1 1 / 1 100 110 130 130 - ( 120-1-1 115-1a T1-S1-E1 T1-S1-E2 T1-S1-E3 T1-S1-E4 T1-S1-En T1 Open T1-S2-E1 T1-S2-E2 T1-S2-E3 T1-S2-E4 120-1-2 T1-Sn-E1 T1-Sn-E2 T1-Sn-E3 - 120-1-4 115-20 T2-S1-E1 T2-S1-E2 T2-S1-E3 -120-2-1 T2 Open T2-S2-E1 T2-S2-E2 - 120 - -2-2 T2-Sn-E1 T2-Sn-E2 T2-Sn-E3 - 120-2-n 115-39 T3-S1-E1 T3-S1-E2 T3-S1-E3 -120-3-1 T3 Open T3-S2-E1 T3-S2-E2 T3-S2-E3 -120-3-2 T3-Sn-E1 izo-3-n 115-15 T1 Close 115-not Tn-S1-E1 Tn-S1-E2 Tn-S1-E3 Tn-S1-E4 -120-n-1 Tn Open Tn-S2-E1 -120-n-2 - - 2 Tn-Sn-E1 Tn-Sn-E2 120-n-n 150 20 26 20 06 56 30 J an 2 02 6 1 / 1 3 0 J a n 2 0 2 6 2 0 2 6 2 0 0 6 5 6 1 3 0 \ ( 1 2 0 - 1 - 1 T 1 - S 1 - E 3 T 1 - S 1 - E 4 T 1 - S 1 - E n T 1 - S 2 - E 4 1 2 0 - 1 - 2 T 1 - S n - E 3 1 2 0 - 1 - 4 1 1 5 - 2 9 - - 1 2 0 - 2 - 1 T 2 - S 2 - E 1 T 2 - S 2 - E 2 T 2 - S n - E 2 - 1 2 0 - 2 - n T 3 - S 1 - E 1 T 3 - S 1 - E 3 - 1 2 0 - 3 - 1 T 3 O p e n T 3 - S 2 - E 1 T 3 - S 2 - E 2 T 3 - S 2 - E 3 - 1 2 0 - 3 - 2 T 3 - S n - E 1 1 2 0 - 3 - n 1 1 5 - 1 5 T 1 C l o s e 1 1 5 - n o t T n - S 1 - E 1 T n - S 1 - E 2 T n - S 1 - E 3 T n - S 1 - E 4 - 1 2 0 - n - 1 T n O p e n T n - S 2 - E 1 - 1 2 0 - n - 2 - T n - S n - E 1 T n - S n - E 2 1 2 0 - n - n 1 5 0
