Problems solved by technology

Such attacks include any effort an adversary might make to disrupt the bounded latency of message delivery for a sufficiently large number of users—for example, by dividing users into two equal-sized groups and controlling the messaging channel between them so that users Messages propagated from group 1 may have an indefinite delay before reaching any user in group 2

Embodiment Construction

[0035] The system described herein provides a mechanism for distributing transaction verification and propagation such that no entity is solely responsible for performing computations to verify and / or propagate transaction information. Instead, each of the participating entities shares in the computation performed to propagate transactions in a verifiable and reliable manner.

[0036] refer to figure 1 , diagram 20 shows a plurality of computing workstations 22a-22c connected to a data network 24, such as the Internet. Workstations 22a-22c communicate with each other via network 24 to provide distributed transaction propagation and verification, as described in more detail elsewhere herein. The system can accommodate any number of workstations capable of providing the functionality described herein, so long as the workstations 22a-22c are able to communicate with each other. Each of the workstations 22a-22c can independently perform processing to propagate the transaction to...

Abstract

In a transaction system in which transactions are organized in blocks, a new block Br of valid transactions is constructed, relative to a sequence of prior blocks B0,..., Br-1, by having an entity determine a quantity Q from the prior blocks, having the entity use a secret key in order to compute a string S uniquely associated to Q and the entity, having the entity compute from S a quantity T thatis one of: S itself, a function of S, and / or a hash value of S, having the entity determine whether T possesses a given property, and, if T possesses the given property, having the entity digitally sign a hash value H of B r and make available S, B r and a digitally signed version of H, wherein, B r may be proposed in different steps of the round r and may be re-proposed multiple times during round r, and an entity may verify a hash value H of a block B independent of whether the entity has received B or not.
