Two double-spend attack strategies on a proof-of-stake consensus are considered. For each
strategy, the probability of its success is obtained, which depends on the network …

Bitcoin falls dramatically short of the scale provided by banks for payments. Currently, its
ledger grows by the addition of blocks of∼ 2,000 transactions every 10 minutes. Intuitively …

Currently, because of the excellent properties of decentralization, hard tamperability, and
traceability, blockchain is widely used in WSN and IoT applications. In particular, consortium …

The paper is devoted to the investigation of the distributed proof generation process, which
makes use of recursive zk-SNARKs. Such distributed proof generation, where recursive zk …

Miners of a blockchain exchange information about blocks and transactions with one
another via a peer-to-peer (P2P) network. The speed at which they learn of new blocks and …

In recent years, blockchain security issues have attracted widespread attention. Especially in
terms of computing power security, when nodes have sufficient computing power, they can …

Electronic trust services are becoming an integral part of the information space. With the
reliable implementation of basic services as an electronic signature and electronic …

In recent years, the possibility of moving from a blockchain to a more general structure,
which has additional capabilities, but remains resistant to major attacks, has been very …

Among the most significant problems that almost any blockchain faces are the problems of
increasing its throughput (ie, the number of transactions per unit of time) and the problem of …

Introduction. In this paper, we obtained for the first time mathematically substantiated
formulas for probability of a double spend attack on blockchain that is based upon Proof-of …
