Hey, ReddHeads!
To new ReddHeads, welcome! To old ReddHeads, welcome back! It’s an exciting time in Reddcoin (RDD) for a lot of reasons, and we, the Reddcoin Core development team, wanted to get a brief update out to touch base on some of the highlights.
Attached are some screenshots of our work to enhance security and interoperability, and to extend support to MacOS Catalina in our newest v3.10.1 wallet.
This wallet release also includes components and performance & security upgrades taken from the Bitcoin 0.10 codebase, and we will be following much of that same development and enhancement in our Reddcoin Core wallet in the future, with 0.11 up next.
This release is not a required upgrade (except for Catalina users), but will benefit user experience and security significantly. We’ll be publishing, of course, a full public changelog, hashes and commit list in Github along with open source code and compiled executables upon release.
But the major changes in Reddcoin v3 are just about to start, as PoSV v2 gets ready to activate. Released to the community on 12/24/19, the blockchain has (at time of writing) reached 8197 of the required 9000 block threshold, or 91.08% of our goal of supermajority. If you haven’t upgraded yet, or aren’t staking, it’s time.
After PoSV v2 activation, older (v2.x, v1.x) wallets will not be able to send transactions or stake.
We anticipate activation to be reached within a very short time period, especially once our Mac ReddHeads are able to participate, and as such we want to ensure that information for the general community is available and up to date.
1) AM I GOING TO LOSE MY REDDCOIN (RDD)??
a. NO. This is a soft-fork, and whether you’ve upgraded to a v3 wallet or not, you cannot lose your coins. The blockchain itself will remain the same, it is only the rules of staking that are changing. Older wallets WILL stop functioning immediately after the threshold is passed and PoSV v2 activates, but all that is required at that point to restore functionality is to install the new v3 wallet. If you need help, please join our Telegram or Discord live chats for community or Dev help directly. No ReddHead left behind!
2) WHAT DO I NEED TO DO??
a. If you’re staking, make sure you’re using a v3 wallet, preferably the latest version. Right now, that is v3.0.1, in a few days with the above noted release it will be v3.10.1. You may also wish to use the “Backup…” function at this time to make sure you have a backup of the only important file you need, the “wallet.dat” file. There are no mobile staking options at this time due to the nature of our PoSV protocol, but you can deposit coins in the dev team-run ReddBot on Telegram to stake if you have no other options until a mobile staking option is made available.
b. If you’re not staking, or are holding on Coinomi, or Guarda, or other 3rd party wallets, or on an exchange, or a paper wallet, you will also have no operational issues, but of course you’re encouraged to help secure the network and validate transactions, by starting to stake.
3) I’M BORED. ENTERTAIN ME!
a. OK. As successful as our first meetup was, we agree. Look for an upcoming benefit concert from Reddcoin and hopscotchmafiamusic.com at the end of this month. No, really. Free awesome music, cool people, come have a bit of fun with the ReddHead community virtually!
4) I’M HUNGRY. FEED ME!
a. Well…with the activation of PoSV v2, and the creation of Reddcoin’s self- funded development mechanism, we’re very excited to be able to provide at least some resources and RDD toward the Reddcoin Community Food & Supply Bank initiative in the near future. Reddcoin Core will also be donating any funds received in connection with the above concert event to worthy and working charities, especially if we can convince them to receive RDD (or BTC). Watch for further info about this and other charity initiatives to come. Our own efforts rely on PoSV v2 activation, but will be documented publicly and transparently as they evolve.
5) I WAS USING RDD AND THEN X (or Y or Z) HAPPENED AND NOW I’M BROKE AND SAD AND ANGRY. HELP ME!
a. Perhaps you’ve not heard about Reddcoin’s uniquely conceived “Reddcoin Restitution Fund”. Been hacked? Lost a few coins when your computer crashed or your brother formatted your hard drive? Reddcoin has committed a percentage of PoSV v2 funding to give back to users legitimately affected by events beyond their control.
Cases of extreme stupidity will be vetted on a case by case basis, obviously fraudulent claims will be laughed at, and all cases will be dependent on a reasonable standard of proof and verification. This is also going to be an evolving and good faith approach to giving back to our real ReddHead community, and will require both transparency and abuse-prevention to be successful, but we look forward to being able to help those who deserve and need it. NOTE: Trading and speculative losses aren’t covered in any of this. Obviously.
6) I WANT TO KNOW MORE!
We’re working right now to rebuild our main website www.reddcoin.com into a more informative and resource-rich site, but it’s a good starting point. We are in the process of updating our roadmap to cover the end of 2020 and the future as well, and both of those should be available and will be announced within the next month.

Tonal Quantum Network - new decentralized own platform for instant information transfer which include

https://preview.redd.it/slwpinqoh9v01.png?width=565&format=png&auto=webp&s=45aa5b105b827e2eb1d02ed0f4e243f454abe42b
Visit our WEBSITE
The Tonal Quantum Network platform (TOQ) – seeks to become world single currency for instant information transfer. The stable and predicted cryptocurrency with quarterly increase in obligations. An opportunity to carry out safe transactions with use of popular cryptocurrency, such as: Bitcoin, Ethereum, Ripple, Monero, ZEC and other cryptocurrency.
The initial purpose of Tonal Quantum – instant payment of mobile network operator through a uniform purse from any point of the world with the minimum commission and also a conclusion and exchange of cryptocurrency without intermediaries and an additional fee.
Main goal of Tonal Quantum – creation of the decentralized own platform for instant information transfer which include:
  1. Confirmation of identity and value (without intermediaries).
  2. Crediting
  3. Sponsorship and investments
  4. Insurance of value and risk management
  5. Accounting of value
We will sort in more detail
1.Confirmation of identity and value. Now we rely on large intermediaries to establish the confidential relations and to confirm identity of other party in financial transaction. These intermediaries act as arbitrators in access to basic financial services, such as bank accounts and loans. Tonal Quantum Network will lower and will even eliminate need for trust for certain transactions. Our service will also allow participants to support confirmed, full-function and cryptographic the protected electronic profiles and to establish the confidential relations, when necessary.
2.Crediting. From a mortgage to short-term bills of Tonal Quantum Network will simplify issuance of credits: the credit cards, mortgage loans, corporate, municipal and state bonds, securities provided with assets. Now crediting has generated a number of additional branches for check of solvency, maintaining credit history, purpose of credit ratings. For individuals the credit history, for the organizations – credit rating, from "an investment class" to "garbage" is the most important here. In Tonal Quantum Network any will be able to release, exchange and settle traditional debt obligations directly, thereby reducing expenses and risk, and increasing the speed and transparency. Consumers will be able to obtain loans directly the same consumers. It is especially important for users not covered bank service and for businessmen worldwide.
3.Sponsorship and investments. Investment into an asset, the company or the new enterprise gives to the person the chance to receive on it profitability in the form of increase in cost of the capital, dividends, percent, a rent and their various combinations. The branch creates the markets, bringing together investors with businessmen and owners of the companies at all stages of development. Attraction of financial resources usually demands intermediaries: for example, investment banks, venture investors, lawyers. Tonal Quantum Network automates their many functions, will make possible use of new models for direct peer-to-peer financing and also will make record of dividends and payment of coupons more effective, transparent and reliable.
4.Insurance of value and risk management. Risk management and its special case, insurance, is intended for protection of individuals and the companies against unforeseen losses or accident. In a broader sense risk management in the financial markets has generated assemblies of derivatives, difficult structured financial products and other financial instruments for hedging against unpredictable or uncontrollable events. By the last calculations, the par value of all large publicly available derivative securities is 600 trillion dollars. Tonal Quantum Network will support the decentralized insurance models that does use of derivative securities for risk management by much more transparent. The system of reputation based on the social and economic capital of the person, his actions and other reputation parameters will allow insurers to understand much more clearly actuarial risk and to make decisions is more informed.
5.Accounting of values. Accounting is a measurement, processing and transfer of financial information on participants of economic processes. This multi-billion branch is controlled by four giants of audit: Deloitte Touche Tohmatsu, PricewaterhouseCoopers, Ernst & Young and KPMG. Traditional practicians of accounting won't cope with the speed and complexity of modern finance. New methods, the applying distributed register Tonal Quantum Network, will make audit and financial statements transparent, and will allow conducting them in real time. Also Tonal Quantum Network considerably will expand a possibility of regulators and other interested persons to keep track of financial activity in corporation.
The new platform allows uniting in real time digital data practically on everything on light. "The register of all" is necessary. Business, trade and economy need digital notation.
How does it concern personally you? We are convinced that the truth is capable to release us and that the distributed trust will exert considerable impact on the person in all spheres of life. Perhaps, you the responsible consumer who wants to learn from where actually meat for his beefsteak has arrived. The immigrant to who has bothered to overpay for money transfers to family on the far homeland. The humanitarian worker who needs to define owners of land possession to restore the houses destroyed by an earthquake. The citizen who wants that activity of politicians became transparent and accountable. To have an opportunity to unmistakably identify the identity of other person to translate and exchange money without confirmation of the third party, for example bank which also demands some percent from the transaction. Thanks to our Tonal Quantum Network through the smart contract the businessman will be able to automate many aspects of activity of the company: purchases, compensation, percent on the credit, financial audit in real time.
«PEER-TO-PEER» or "without intermediaries"
Now there are many huge companies which help to connect the consumer with the supplier. But change of the centralized company the distributed P2P Tonal Quantum application (Peer-to-Peer Tonal Quantum) will come.
For example:
When the tenant looks for the room, the software of P2P Tonal Quantum looks through contents of our blockchain network, finds all offers and shows to the user what corresponds to the set filter. As the network writes down information on transaction in blockchain, the positive review of the user strengthens reputation both the tenant and the lessor and identifies their personality – but now without intermediary.
For the first time in the history of the party will be able, without knowing each other and without trusting each other, to conclude bargains and to run business. Confirmation of the personality and establishment of trust have stopped being the right and the privilege of the financial intermediary. Moreover, in the context of financial services the protocol of trust will gain new value. Tonal Quantum Network will be able to establish the confidential relations when they are necessary, having confirmed identity and solvency of each party by means of history of transactions (in blockchain), values of reputation (on the basis of the aggregated responses) and other socioeconomic indicators.
Our system at the moment works at Blockchain Ethereum, and will pass to the new Blockchain platform soon – Tonal Quantum Network with use of Quantum and computing technologies. On him the Tonal Quantum Network will also be built. Work with quantum – logical elements which are at the same time in superposition of states "0" and "1" is the cornerstone of quantum calculators. At measurement of qubit there is a destruction of superposition and with some probability one of these two states drops out. Operations over qubits change probability of loss of this or that value. In usual computer tasks (for example, additions of numbers), the quantum system won't be able to bypass classical, but the situation changes when in a task search of a huge number of options and optimization of multicomponent system is required. Specialized tests of the calculator, according to the company, have shown his superiority over classical processors by 1000 – 10 000 times. In the world there are no universal quantum computers capable to cope with any tasks yet, however there are worked methods and the principles of calculations and already now will allow our Tonal Quantum Network to solve super difficult tasks. Our investors are interested in our project and at present negotiations with the company on gaining access to Quantum and computing technologies for support of our Tonal Quantum Network are conducted. Classical schemes of blockchain are used generally only for cryptocurrency, and our Tonal Quantum Network will be applied to drawing up smart contracts, storage of information on intellectual property rights and other data. A task of quantum network Tonal Quantum Network to secure classical schemes against unauthorized signing up in network. Besides, in the new concept there is no classical paradigm of Blockchain that any participant of network can form blocks. Instead generation of blocks will happen is decentralized. Our system is capable to support functioning even if a third of knots will "unfair" behave.
The TOQ cryptocurrency will be written on a new algorithm, for our platform. The main power will be allocated for support of Tonal Quantum Network, and other power will use the PoS mode (Proof-of-stake) for this TOQ cryptocurrency.
Power Quantum Netowrk

65% of capacity allocated to support Blockchain network
20% capacities for support of transactions in network
15% capacities for production of cryptocurrency of network to users
Advantages our system
  1. All network Tonal Quantum will be decentralized, and all operations will be supported by Tonal Quantum Network that gives advantages to users to pay the minimum transaction commission.
  2. This commission will go for ensuring maintenance and development of the platform.
  3. Transactions will take place for only a few seconds.
  4. The system will also work in two modes: PoS (Proof-of-Stake) and PoW (Proof-of-Work).
  5. For miners of PoW the separate pool which will reward miners without the commission of a pool will be started.
  6. For holders of coins of PoS all coins got by system will be automatically charged to users (holders of coins). Charge will be calculated based on the ratio of 40000:1.
All coins got in the PoS mode will be distributed equally, depending on quantity of the coins which are stored in the user's purse.
From these transfers you at any time can pay the bill of mobile network operator or exchange them for any other cryptocurrency without the commission.
After start of the Tonal Quantum Network blockchain-platform anyone will be able to participate in a procedure of migration of a token from the Ethereum platform, on the Tonal Quantum Network blockchain-platform at a course 1 to 1 at which the holder of TOQ will have all stated additional opportunities.
Also the Tonal Quantum Network Cryptocurrency exchange where there will be auction not only to TOQ coin, but also to tokens, created on the Tonal Quantum Network platform will be started.
https://preview.redd.it/1xzzf032k9v01.png?width=528&format=png&auto=webp&s=63a0c36653749bd7a386999749ae4d9b5f5e26c7
Service offers instant exchange at this rate of cryptocurrency and without the commission to make exchange for a coin of TOQ or for other cryptocurrency and to make payment.
Our service on a straight line contacts bank and sends money to the mobile operator with converting in different currencies (USD, EURO, RUR).
The operator in turn sends transaction to the user and deducts 2% of amount of transfer in our bank and these bonuses will be included in money transfers.
The initial Tonal Quantum Network platform will allow users to make online translations, payments for the mobile operator and trade in cryptocurrency through our service. Payment will happen both to a token (TOQ), and to any other token, also service gives an opportunity to users instantly to exchange any cryptocurrency for TOQ without the commission.
Likely many faced a problem of exchange of cryptocurrency. It is a lot of companies and various services (websites) give this opportunity and respectively take the decent commission for these manipulations.
We, offer you a conclusion of cryptocurrency through our uniform service which will work for a straight line with bank.
We seek to simplify daily actions and to reduce losses which meet in our life absolutely everywhere.
We won't entice investors beautiful pictures and advertising.
Those purposes which we have told you above and those financial means which we could spend for advertising, Are important for us will go specifically for creation of the Tonal Quantum Network platform.
We undertake to submit the report on each our done work to our investors!

Ethereum Research Directions

Hello potential research collaborator! Rumour has it that you, a researcher or manager of researchers, are interested in joint research with the Ethereum Foundation. Below are the primary topics the Foundation will be thinking about for the next 2-3 years. If you, like us, enjoy the prospect of thinking about one or more of these topics for the majority of your waking hours, do get in touch. The Foundation does have money to pay the salaries/stipend of those undertaking high-value research.
We have topics in both pure research and applied research. The Foundation as well as the larger Ethereum community seek help on both. Typical outputs from researchers are: peer-reviewed academic papers, technical reports, and/or implementations (prototypes as well as production-ready).
Questions in Fundamental Research Q1: Can we create a theory of cryptoeconomic mechanisms? There are certain patterns that are often used in cryptoeconomic mechanisms. These can be studied in the abstract independently of any specific use case. Security deposits (see also proof of stake) How do we model capital lockup costs? Dual-use of security deposits Challenge-response games (one group of actors is given the opportunity to submit evidence that fact X is false, and if no one submits evidence within some period of time, then X is assumed to be true). See also challenge-response authentication. Channels State channels How do we minimize the vulnerability of challenge-response games and channels to liveness or censorship faults of the underlying blockchain? Escalation games Cross-chain interoperability (see the R3 interoperability paper ) Relays Hash timelock atomic swaps Q2: What is the role of cryptoeconomics in distributed systems? What is the role of economics in cryptography? Can we formalize how algorithmic incentives (“cryptoeconomics”) can enhance information security?
Modeling behavior of participants in mechanisms
Simple (crash) faults Byzantine faults (arbitrary) Byzantine-Altruistic-Rational (BAR) model Uncoordinated majority (e.g., as in selfish mining) Coordinated choice Bribing attacker (as in P+epsilon attacks or iceman) Behavioral economics models (prospect theory, endowment effect, loss aversion, morality, etc.) Complex game-theoretic interactions
Blackmail Quantifying cooperative interactions among agents (e.g. dynamic coalition formation) Evolution and enforcements of group norms Q3: How do distributed systems influence current economics? On net, when and how much does decentralization lower transaction costs? No obvious answer. Decentralization _decreases_transaction costs because of: Reduced number of counterparties and reduced need for building trust Yet decentralization increases transaction costs because of: increased technical overhead, Decreased usability, increased responsibility. Are Transaction costs = transaction fees + coordination costs? Q4: Within game-theory, can we quantify coordination costs? for players running a particular protocol for players executing a particular strategy Q5: What are ways we can manipulate (e.g., guarantee/minimize) coordination costs? For example, we can reduce risk by increasing coordination costs. Coordination costs are costs from multiple-agents coordinating. For example: Discovering potential peers, agreeing on computing coalition strategies, synchronization required for execution, costs of proving to the coalition that players followed coalition strategies, cost of getting rid of individual incentives to deviate Q6: What protocols have better fault attribution? A protocol fault is uniquely attributable if there is evidence that could be used to umambiguously convince any observer which actor caused the protocol fault. If a fault is non-uniquely-attributable, the blame for the fault can often at least be narrowed down to within N specific actors.
Fault attributability in various consensus algorithms
Chain-based (synchronous) consensus Partially synchronous consensus (see minimal slashing conditions) Common coins in asynchronous consensus Attributability of censorship or liveness faults.
Translating fault attributions into penalties
Shapley values Q7: What are decentralization’s fundamental limits? Building on hundreds of impossibility results. E.g., 1 and 2, or even fundamental limits from other areas of computer science.
What centralized protocols can be decentralized (while preserving guarantees)? At what cost in protocol overhead? Are there limits to scalability? For Bitcoin: On Scaling Decentralized Blockchains Only because of the requirement for shared state? At what cost in incentivization? What are the limits to incentivization? Limits to attribution Limits to mechanism budgets With how much security (against coordinated choice, trusted majority required)? Limits to fault tolerance e.g. in objective protocols and subjective protocols Objectives in Applied Research Also knows as Pasteur’s Quadrant.

An overview of in-person POS and payment gateway solutions for small businesses (in the US)

Bitcoin acceptance solutions for online merchants are fairly numerous, but the options for in-person transaction solutions by physical merchants are rather limited and underdeveloped. As I've been working with a small business right now to integrate Bitcoin payments, I thought I'd share my own experiences and opinions on our present choices. Here are the various ways I can think of to accept bitcoin payments for in-person transactions, with comments:
Pros: Simplest to setup with high versatility for managing payments and choosing services on the backend. No merchant account required.
Cons: Static addresses are terrible for personal and network privacy. Hard to verify payments depending on the backend solution and availability to the cashier at the time of the transaction. Requires the use of some other currency exchange conversion tool to generate BTC amount. Burdensome on the customer to manually type in transaction total and requires trust or verification that they do so accurately. Limited-to-no bookkeeping export.
Pros: Use of proven software and existing knowledge making business setup easy. Potential, though limited, for dynamic address generation per transaction. Potential use of existing hardware (computer or staff's phones). Widespread availability of built-in currency conversion and encoding into an address+amount QR codes. Widest selection of software.
Cons: For dedicated devices, unlimited access by staff to wallet balance and send functions (unless secured by passcode requiring authorized user presence and effective procedures for use) -or- use of staff's personal devices (unless dedicated phones carried by authorized users). Likely use of static addresses with negative privacy implications. Typically slow and error-prone to convert currency totals and present to customer (e.g., must select correct currency denomination, bring up mobile keyboard, be sure to type a decimal point in the right position). Potential for showing wallet balance to the customer. Limited to no bookkeeping export.
Pros: Faster, less error-prone total entry and checkout processing with address+amount QR display. Potential for an all-in-one solution to Bitcoin acceptance with customer support and minimal or no handling or understanding of Bitcoin wallets, addresses, ect., by merchant staff. Potential for automatic bitcoin conversion to local currency with deposit to a business bank account. Potential for sales item setup and easy tap-to-add ordecart generation with sales tax addition. Potential for Payment Protocol (BIP 70-73) support. Likely use of dynamic address generation per transaction. Some bookkeeping export. Potential to avoid bookkeeping complexity with capital gains and separate currency tracking via daily currency conversion.
Cons: More complicated setup and testing. Dedicated hardware recommended. Very limited app and processor selection at this time. Less tested and more experimental. Merchant signup and approval likely needed. Recurring or per-payment costs for backend services. Likely limited backend technical support.
Pros: Most elegant solution for bitcoin payments. Bitcoin included as an option along with other payment methods without switching programs. Easiest to use and train staff to use. Possibility to include Bitcoin as one of multiple split payments in a single transaction. Inclusion in standard receipt generation. Tracking in POS suite along with other payment methods. Best bookkeeping support. Best technical support. Potential to support Bitcoin debit cards.
Cons: Most expensive (by far), unless writing your own API-based custom software. Custom software requiring the most testing. Better for medium-to-large size businesses. Dependent on POS solutions provider for continued Bitcoin support.
My recommendation: The best compromise between privacy, convenience, speed, reliability, setup time, cost, and complexity right now seems to be BitPay with their device-independent hosted checkout (recently updated to work much better) that you can keep open or bookmarked in a browser on a computer, phone, or tablet. Coinbase with the Coinbase Merchant app I can't recommend right now due to significant delays in my tests before the app would recognize payment. The Coinbox app linked to Coinbase solves this problem and functions beautifully, but right now it is not generating dynamic addresses (a bug I've reported). Coinbox linked to BitPay has a more serious bug (also reported): Rounding mismatches upon currency conversion.
If you don't care about address reuse or the merchant is willing to periodically generate new addresses, then any of the regular wallets could work including CoinBox + Coinbase (you can periodically reset and relink CoinBox to generate a new address). A business-dedicated tablet is what we use at Boss Stage Arcade.

Adopting POS can cut down the energy cost to considerable amounts. Hence, POS coins mined in this manner are way more energy efficient than coins that are based on Proof of Work algorithms. 2. In POW based mining, the miners don’t own the coins and look for maximizing their profits. Under POS, those guarding the coins will always own the coin. Coinbase, a cryptocurrency exchange, also offers a merchant app for businesses for bitcoin payment services. CoinGate, SpectroCoin, and CoinsBank are other leading players offering similar ...
