TOLAR: A UNIQUE CRYPTOCURRENCY EXCHANGE

Potentially faulty or malicious nodes provide an additional challenge of implementing a
consensus protocol in an asynchronous environment. In fact, it is well-known that it is
theoretically impossible for any deterministic protocol to reach an agreement in such
environments [16]. Thus, our implementation resorts to a class of so-called iterative randomizedapproximat consensus algorithms. The goal is to allow fault-free nodes to agree on values, overcoming the obstacle posed by (possibly incorrect or unreliable) information disseminated by
faulty nodes. Theoretically, the most challenging case are leader-based consensus algorithms, which rely on a small number of nodes that cannot be faulty (e.g., such as [8]). Such protocols are
prone to failure and usually exhibit several unresolved issues in the case of a malicious node becoming a

THE PRODUCT AND BUSINESS OVERVIEW 4.1. Introducing HashNET HashNET is scalable, efficient and high-impact decentralised solution to social innovation challenges leveraging Distributed Ledger Technology (DLTs). This revolutionary algorithm features faster transaction time, masternodes and will have an open source, community governed crypto-currency — Tolar. DLT in its public, open and permissionless form is widely considered as a ground-breaking digital technology supporting decentralized methods for consensus reaching, as well as sharing, storing and securing transactions and other data with fewer to no central intermediaries. HashNET consensus uses “redundancy reduced gossip” and “virtual voting” protocols based on a distributed computation and algorithms from theoretical computer science, which provides a fair and fast, byzantine fault tolerant consensus algorithm. It is a new consensus substitute platform and is designed to run on a non-permissioned (public) network.

HASHNET UTXO STORAGE REQUIREMENTS
In addition to aforementioned speed performance guarantees made possible by HashNET design, we are also able to guarantee improvements in the global data storage size. Specifically, HashNET data storage is designed by generalizing the approach laid out in MimbleWimble whitepaper
The main benefit of this approach is that it manages to simultaneously handle security and versatility.We utilize concepts such as Confidential Transactions and "One-Way Aggregate Signatures"OWAS), which are shown to provide private exchanges and better adaptability. The main ideabehind OWAS is that when the outputs are created and destroyed, it is the same as they never existed. Consequently, to approve the entire chain, a client only needs to know when coins were
