Welcome to DACash!

Intro
Every day, more and more people understand the change and benefits that cryptocurrencies bring to our world. Cryptocurrency is inherently a morally-neutral technology. By aligning incentives in the DACash, the morally-neutral nature of cryptocurrencies can be transformed into a positive and powerful force of change in our world. As its known, the decentralisation of cryptocurrency is achieved by the fact that each node of the network is capable of validating transactions independently by storing of its own replica of the blockchain that it can use without relying on other services. Users can share their nodes for connection to others, which is important for network enlargement and speed of initial synchronisation of new connecting nodes and speed of message distribution. At the same time, users do not have to do this, leaving the right to keep their node in a passive mode without publishing it.
The X11 algorithm used to secure the blockchain, utilises multiple rounds of 11 different hashes, thus making it one of the safest and more sophisticated cryptographic hashes in use by modern cryptocurrencies. The increased complexity and sophistication of the chained algorithm provides enhanced levels of security and less uncertainty for a digital currency, compared to single-hash PoW solutions that are not protected against security risks like SPOF (Single Point of Failure). Given the speculative nature of digital currencies and their inherent uncertainties as a new field, the X11 algorithm can provide increased confidence for its users and potential investors that single-hash approaches cannot. Chained hashing solutions, like X11, provide increased safety and longevity for store of wealth purposes, investment diversification and hedging against risks associated with single-hash currencies.
In addition to plain user nodes (wallets), the DACash network also has an additional layer of services provided by so called masternodes. Masternodes are the same nodes of the network, running the same code as any user’s node. They also store a chain of blocks, provide relaying of blocks, transactions, and perform their validation on the same terms as any other network members. In addition, masternodes can provide additional services, the appearance of which makes the DACash network two-storing, rendering the processing of these services on a separate layer of nodes instead of loading the entire network in total by them. Masternodes provide such services as InstantSend and PrivateSend. In addition, they can vote for governance proposals to distribute reserved budgets to proposal owners. The reward mechanism motivates masternode holders to provide guarantees of their increased accessibility.
Any node can become a masternode. The activation process takes place in two stages: first of all, it’s necessary to transfer exactly 1000 DAC, so called collateral, to any own address of this node with one transaction, not more or less. The transaction will get into the blockchain, and the whole network will make sure that this address is capable to sign service messages as a masternode. The next step is to broadcast the masternode data to the whole network via directly connected peers. Those peers, in turn, are checking the validity of the message, and if all is good, they relay the announcement to all their peers. Quite so the masternode data is distributed throughout the network. From this moment the network recognises the existence of a specific masternode and includes it into the voting and reward lists. For the correct operation of the provided services as well as for the honest distribution of rewards from mining across all network masternodes, an untainted way is needed to agree on which of the masternodes will be required to undertake these tasks. In DACash this problem is solved by the algorithm of queue predetermination and the principle of achieving non-trusted quorum.
One of services that masternodes provide is InstantSend. It relied on the generation of masternodes quorum according to the principles described earlier: determination of the list of the nearest masternodes in the queue, and sending the InstantSend request to all of the nearest nodes in the 10-node queue. The masternodes take a request to create a transaction lock so that the same input could not be used twice in another transaction, but only in the sending transaction. The blocking of the transaction takes for about 4 seconds on the average. Any subsequent attempts to send the transaction with the same output, but inconsistent to the previous transaction id, will be perceived as invalid and will be ignored by the network until the confirmation of the previous already sent instant transaction. InstantSend transactions get 5 confirmations instantly and the next block found provides the final, 6th confirmation. This will be displayed both for the sender and for the recipient.
Another masternode service is PrivateSend. It is a service of mixing payments, which is integrated into the DACash client program (wallet). PrivateSend includes a number of procedures. Preliminary denomination – payments are split into equal parts: 10, 1, 0.1, and 0.01, which prevents tracking by explicit amounts. Every part goes over its own stages of anonymization:
● Not all amounts are mixed, but only some of them.
● Exclusively matching by value denominations are being mixed.
● On each step a new mixing masternode is selected.
Mixing happens preliminary. After mixing the amount goes back to the owner into new anonymous addresses, and can be used when it’s needed.
The most interesting thing about the masternodes network is that people can freely come and go, that’s why the success of this network does not depend on the specific users. It makes the network a decentralised structure. You have to invest 1000 DAC to become a masternode and not to use these coins while the masternode is active and gets paid for its services. It means that you shouldn’t withdraw, convert or even send this amount somewhere from your wallet. As soon as you destroy the result of collateral transaction, your masternode becomes expired, you will lose the right to vote and getting masternode rewards.
Reward System
Miners and masternode holders get paid for providing network services. Miners secure the blockchain by running Proof-of-Work algorithm using ASIC hardware and paying electricity bills. Masternodes provide other services to the network and also get paid for their availability, paying for servers and resources used. The DACash block reward is 100 DAC initially and is split into 50% of reward for the miner found the block, and 50% of reward to the masternode in the payment queue. To limit the total supply the block reward will be lowered later, and total supply is projected to be around 50M DAC.

Vision
DACash team is committed to create a globally influential open source community by cooperating with other blockchain communities, third-party developers, and technical innovations. The Ultimate goal of DACash is to bring blockchain technology into the Internet of Things (IoT), and other industries. Data feeds in conjunction with the logic of regulation are to bridge the real world to the blockchain world. As an open source community, the DACash team has built a platform that is secure, reliable, and compatible with the Dash community and the Bitcoin system. It also integrates on-chain and off-chain data through technical and conceptual innovation. In order to ensure the sustainable development of the DACash, the team will refer to investment practices to perform industry analysis and selections and to choose the appropriate industries to implement DACash technology.
There are some tasks we have to implement first. At the moment we can tell that one of our research areas is the Internet of Things. The number of IoT devices increased 31% year-over-year to 8.4 billion in 2017 and it is estimated that there will be 30 billion devices by 2020. The global market value of IoT is projected to reach $7.1 trillion by 2020. The Internet of Things (IoT) is the network of physical devices, vehicles, home appliances and other items embedded with electronics, software, sensors, actuators, and connectivity which enables these things to connect and exchange data, creating opportunities for more direct integration of the physical world into computer-based systems, resulting in efficiency improvements, economic benefits and reduced human intervention. IoT frameworks might help support the interaction between "things" and allow for more complex structures like distributed computing, consumer applications, infrastructure applications, enterprise applications. IPv4 address space is limited (4 bytes). MAC address space is a bit better (6 bytes), but IPv6 is practically endless. DACash Core supports IPv6 as well as Tor/Onion wallets/nodes. We have some ideas regarding IoT devices connected to DACash Core nodes using IPv6. Currently, some IoT frameworks seem to focus on real-time data logging solutions, offering some basis to work with many "things" and have them interact. DACash Core provides this type of functionality for the Internet of Things. There are currently scientific studies that will add more information.
We expect that there will be many applications and end-user solutions developed using the DACash Core. DACash Core will provide support for business development by using industry focused consensus mechanism and incorporating regulatory requirements. DACash Core also can support many industry application requirements, such as finance, logistics supply chain, social and gaming, charity, digital assets, stocks, etc. Through collaboration with business partners and integration of resources from companies, businesses, technology communities and governments, the DACash Core will make the most efficient use of shared resources to achieve synergetic development with society.
We expect that the market price of DACash will be quite stable. Since it is a PoW blockchain, it always needs some investment into the mining hardware and electricity. So miners should not allow the price to dump. We expect to make x11 ASIC mining of DACash attractive. We refuse aggressive advertising, believing in our ways and goals set for DACash. The advertisement campaign should be clear and smooth, targeted at miners and potential investors first, end users next. We are interested in slow but stable growth of the DACash community. We don’t like an idea of SPAM ads, cheap crypto-forum ads, off-topic ads, aggressive social network ads. Instead, we prefer a quiet launch and gradual access to the crypto currency market in order to justify the hopes of people who believe in DACash and see the perspective in the system as a whole. We are interested in global strategic partners, who in the early stages will be able to render invaluable support to the DACash start-up, in any information direction, in development, integration, scalability. In turn, we suggest that early investors become masternode operators in order to take full participation in the further joint development of the project. DACash have a budget of 1’000’000 DAC for listing to exchanges, financial and masternode monitoring sites, advertisement, supplemental services, software development (own and contract/freelance developers), early investors. The preferred way of payment is in DAC unless there is an established scheme (particularly, for exchange listings). Our ultimate goal is to stay in the crypto-currency industry for a long time.
Open source
In the DACash team we believe in openness and transparency, we support the open source idea, all of our developments will be made available to everyone on our GitHub repository (https://github.com/dacash-official/dacash). Open sourcing our project will help to promote innovation. We welcome contributions from anyone who wishes to improve the project.
This project would not be possible without the previous work of the Bitcoin and Dash development teams. We appreciate their efforts greatly. We are excited to belong to an open source community and appreciate the opportunity to contribute to this growing technological field. In addition, we thank the passionate members of the DACash community who have grown this project and participated actively in the evolution of DACash.
