Definition of White Paper “A white paper (sometimes referred to as a white book) is a report or guide that informs readers concisely about a complex issue and presents the issuing body's philosophy on the matter. It is meant to help readers either understand an issue or solve a problem or make a decision” ( https://en.wikipedia.org/wiki/White_paper ) Executive Summary Nowadays more and more people tend to enjoy the benefits of a cashless society. Furthermore - as security and safety come first in terms of digital usability - the use of the Blockchain technology is inevitable. As we strongly believe in the technological breakthrough of the cryptocurrency economy, we have created a cryptocurrency that is able to offer the safety, the speed and the transparency of the blockchain technology as well as the usability of the conventional banking currency. At the moment these lines are being written more than a few thousand of cryptocurrencies already co-exist around the global crypto-economy. We believe that a cryptocurrency should function as its name states, as a currency. We strongly believe that it should have an even better usability than the fiat money. HNC makes the difference in usability, in transaction speed and security. HNC has been built on state-of-the-art technology in order to make a reality today, the future of digital means of payment. HNC can be used as a means of payment in the global digital world. It can be the key for digital payments, including merchant payments and cross-border currency exchanges/transfers. HNC aims to bridge the gap between traditional and digital money. This goal will be achieved within the reward program and the earnings each customer will get back when using the HNC Debit Card as a means of payment in the real economy. And what is the most important is that the HNC is available to everyone – from everyday consumers to businesses of all sizes. All the above make HNC unique and revolutionary.

Blockchain Summary HNC was developed in February 2015 and it is a fully decentralized peer-to-peer protocol with its own blockchain. Currently and after its latest hardfork in 2021, its name has been changed into HNC Revolution and its blockchain has migrated to “Proof of Service” X11 SHA3 Dash algorithm. The HNC Revolution aims to provide a fully transparent Dual Asset which combines an extremely fast and secure alternative means of payment as well as an investment asset. HNC Revolution open-source code will be available on “Github” within Q2 of 2021. X11: What is it exactly? X11 is a crypto algorithm designed in such a way that it uses a sequence of different hash functions and it aims to offer the best possible security to cryptocurrency mining. At first, X11 was implemented into the Darkcoin protocol in 2014 (currently known as DASH). X11 was selected and developed for DASH in order to offer better privacy, native anonymity and make the cryptocurrency more resistant to specialized mining devices like ASICs (Application-Specific Integrated Circuits) Unlike Bitcoin that uses the SHA-256 algorithm, X11 is not a single hash function mining algorithm. X11 combines 11 scientific hashing algorithms for the proof-of-work. This is why the processing distribution remains fair. The main idea behind this is to make it more complex for ASICs to complete mining, thus giving the users using CPU’s and GPU’s the chance to remain competitive. This aims to make it more resistant to centralized mining. Hellenic Coin Revolution (HNC) Whitepaper Version 4 (March 2021)
How it works: When a value is submitted, the first function produces a hash which is then submitted to the following function to produce another hash. The X11 algorithm is comprised of the following hash functions: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. BLAKE BLUE MIDNIGHT WISH (BMW) Grøstl JH Keccak (An algorithm whose variant gave rise to SHA-3) Skein Luffa CubeHash SHAvite-3 SIMD ECHO All of the algorithms above were entered into the U.S National Institute of Standards and Technology (NIST) open competition in order to develop a new hash function - SHA-3 - that was more secure than the previous generations: SHA-1 and SHA-2. Out of the 64 algorithms that were entered into the competition, all the X11 hash functions were accepted as first-round candidates. Out of the 14 second-round candidates, all the X11 algorithms were once again accepted, with the only following functions making it into the final 5: BLAKE, Grøstl, JH, Keccak and Skein. Keccak would then be the function to win the competition. In short, the involvement of these functions in what was a 5-year long competition, speaks to their security and credibility (https://www.mycryptopedia.com/x11-algorithm-explained/ ). • Advantages of X11 A higher level of security compared to hash functions like SHA-256. This is because several hash functions are used and not only one. This provides a higher degree of protection against attacks. Environmentally friendlier. X11 is less demanding in terms of computing power. The mining process requires significally less energy. The algorithm is open to configuration to use more hash functions than the specified 11. Additional hash functions can be added, like X13 or X17. Hellenic Coin Revolution (HNC) Whitepaper Version 4 (March 2021)
• Disadvantages of X11 No longer ASIC’s resistant. Although it was launched at first to be more resistant to ASIC’s mining systems, nowadays there are several ASIC miners on the market that can offer high mining power for X11. Dual Consensus: Proof of Work & Proof of Service HNC - like most other cryptocurrencies - is based on a decentralized ledger for all transactions, known as a blockchain. A blockchain is consisted by blocks. These blocks contain information about the transactions that have been verified by the network. As in the case of Bitcoin, the network verifies the blocks through the mining process and the blockchain is secured through a consensus mechanism known as Proof of Work. In HNC’s case, another system works simultaneously to secure the blockchain: Proof of Service. The objective of this dual system is to capture the benefits of each different system and combine them in order to balance the weaknesses they have. Proof of Work: What is it exactly? Proof of Work (PoW) is a system commonly used to prevent double-spends. It is widely used by several cryptocurrencies as their consensus algorithm and it is a way of securing the cryptocurrency’s ledger. PoW is complex (time-consuming, expensive) to produce and its purpose is to check if calculations were indeed conducted during creation of a new block of cryptocurrency. The widely known cryptocurrency Bitcoin uses the so-called "Hashcash" function as evidence of work carried out to solve complex mathematics in order to create a new block. The difficulty for the PoW to be solved is varied in order to control the discovery frequency of new blocks. The algorithm works in such a way that one new block is created every 10 minutes on an average scale. The blockchain consists of different blocks. Each block has its own hash address that derives from the information it contains, including the hash address of the previous block (parent block). Due to the fact that the network verifies the blocks, it is impossible to alter information in an already created block because this means that its hash would have to change. But if its hash changes this means that also the hash of the following block in the chain has to change because it must contain the new hash of its parent block and so on. As this is a very difficult task, this protects the blockchain from unsanctioned access and double-spending attacks. Hellenic Coin Revolution (HNC) Whitepaper Version 4 (March 2021)
Double-spending is used almost exclusively in a digital money system and it is a potential issue where the same digital money or assets are spent to two different recipients at the same time. Basically it ensures that users aren’t spending money that they don’t have the right to spend. If no countermeasures are taken to prevent double-spending, users have no way to verify that the funds they have received, have not already been spent elsewhere. That would lead to the digital currency’s collapse. Advantages of PoW • • Rewards for each valid block It is not necessary for someone to have much computational power in order to verify that a block is valid. Disadvantages of PoW • • It is very expensive for the average user to mine in most cases It has become a very unfriendly technique environmentally as it consumes a lot of electric power Proof of Service and Masternodes: What is it exactly? Certain accounts that fulfill the appropriate criteria - in terms of performance, functionality and coin ownership - can become a masternode. In HNC’s case, every node that owns 1.000.000 HNC, has the option to become a masternode. A masternode has a full copy of the HNC blockchain and performs tasks such as block validation, PrivateSend and InstantSend (PrivateSend is a function that enhances user’s privacy by obscuring the origin of funds and with InstantSend the user is able to instantly send to another wallet up to 2.000 HNCs). The masternodes will receive payments for the above mentioned services. This whole procedure is called Proof of Service and it works simultaneously to the Proof of Work done by miners to secure the blockchain. Furthermore, the masternodes will have the option to vote on the governance and funding proposals of the whole project. Due to the fact that certain business decisions have to be taken we believe that the most democratic way is to carry out a voting process among those who have something to benefit from the project and also something to lose. As earlier said, everyone can become a masternode as long as they fulfill the appropriate criteria. Each masternode can have one vote. If the majority of the masternodes have a positive vote then the proposal is accepted and vice versa. Hellenic Coin Revolution (HNC) Whitepaper Version 4 (March 2021)
There is a distinction between masternodes and miners. The masternodes do not mine and mining computers cannot serve as masternodes. The miners’ power enables sending and receiving of funds as well as prevent the double - spending while the masternodes provide the services for PrivateSend, InstantSend and the governance. Initially 10 masternodes are going to be created on behalf of the HNC Project that will provide services for the PrivateSend, InstantSend and governance services. The masternodes are going to be paid by the network for their services with 99% of the block reward. The rest 1% will be paid out to the miners. With the earnings from the reward system the project will have the option to fund certain acts such as advertising, blockchain developing, cooperation with third party companies in order to satisfy the best interest of the project etc. Mining Proof of Work (PoW) & Proof of Service is the dual consensus algorithm that HNC uses. Mining is the process through which transactions get verified and added to the public ledger - known as blockchain. Throughout the mining process miners reward themselves with new HNCs. When a transaction is about to be executed it gets listed among other ones that have already been submitted within a cryptographically-protected block. So each block includes information regarding its transactions. Miners try to check the validity of these transactions through Proof-of-Work. They solve rather complex mathematical problems passing the data within a block through the algorithm until their collective power finds a solution. They also check incoming transactions against previous transactions on the blockchain and - if no double-spending is detected - then the miners create and verify the new block which contains all the new transactions and add it to HNC's existing blockchain. Each new block is then being sent to the network’s nodes. The nodes use the miners' work in order to continue to verify and transmit transactions across the network. As stated earlier, 99% of the block reward from the mining process goes to the Masternodes and 1% goes to the miners. Hellenic Coin Revolution (HNC) Whitepaper Version 4 (March 2021)
Current Landscape Since its inception in 2009 the cryptocurrency market has marked a tremendous growth. Within the last 12 years the market capitalization of all cryptocurrencies and coins has risen to $1 trillion (January 2021), easily dwarfing almost every corporation in the “S&P 500” as well as the GDP of many countries. It is widely accepted that blockchain is world’s most innovative technology as well as that cryptocurrencies will be defined as assets by the authorities. Banks, corporations, funds and big investors have changed amazingly their point of view towards the cryptocurrencies and they have become more crypto - friendly by investing huge amounts on cryptos. Governments are planning to digitalize their fiat currencies too. Top cryptocurrency exchanges - in terms of volume exchange - have already started to work on a regulated environment in order to support legit services based on safety and security, providing trading pairs with fiat money as well as bank services, like SEPA transfers and swift. Lots of such exchanges offer services such as cryptocurrency custody. Wall Street offers futures of cryptocurrencies. Furthermore, many platforms also provide Crypto - CFDs services and many top regulated and licensed exchanges offer the option to use margin for trading Cryptocurrencies. Nevertheless the huge growth of bitcoin and altcoins have led to a new financial era. When Bitcoin appeared back in 2009 regulations did not exist at that time. Nowadays, governments and Central Banks have recognized the advantages of the blockchain technology and have accepted the importance of cryptocurrencies. The global imprint of the crypto-economy is so big that it needs to be regulated and controlled. The reason behind this is simple: everybody needs to act with safety and if problems occur there have to be rules, so that solutions can be found. Government regulation is inevitable Government reactions to cryptocurrencies have ranged from aggressive to indifference with investors and speculators cautiously monitoring international developments. Just recently Head of the International Monetary Fund (IMF) – mrs. Christine Lagarde - stated that regulatory action upon cryptocurrencies is "inevitable“ on behalf of the international community.
