ISO 4217 -

Call for action: there are only 23 BTC ATM's in the OpenStreetMap database...

Take a look at current state of BTC ATM's in OpenStreetMap: (see EDIT, this is incorrect filter, it should be XBT)
Or run query yourself: (please don't do "Reddit hug of death):
(see EDIT, this is incorrect filter, it should be XBT).
OpenStreetMap being open platform for mapping the world (from countries to streets to hiking roads to benches or even trash cans) seems in the same open nature like Bitcoin is.
So, please consider contributing Bitcoin ATM's to OpenStreetMap database!
You can do that using editor (create account and press Edit), or install mobile editing app like Vespucci (or others), or full-powered JOSM (for desktop).
Check OpenStreetMap wiki page about ATM. Basically it's "amenity=atm" with "currency:BTC=yes" (see EDIT) "currency:XBT=yes". Add other appropriate tags too, like operator, other currencies and others.
Yes, I know we have (and maybe others), but these closed/proprietary sites might go "out of business" any time and we will lose all the data. Meanwhile, you can host your own OSM server if you will!
EDIT: actually it should be currecny:XBT=yes as of this note:
For Bitcoin, please use currency:XBT=* instead of currency:BTC=*. In fact "XBT" is ISO 4217 compliant.
Still, shows 386 ATM's if I filter for XBT, which is much less (order of magnitude) than of total atms.
So first we have to fix currencty:BTC to currencty:XBT.

Test results TkeyNet, release date, and the opening of an office in the UK.

Test results TkeyNet, release date, and the opening of an office in the UK.
Hello everyone! Today we will talk about the results of the development of the TkeyNet system and related products, as well as share the test results and release date.
To date, the Protocol has fully debugged. The process of debugging the TkeyNet system is moving with decisive steps — 94.7% of testing of all the functions that TkeyNet includes has completed.
During the tests, the following properties and functions tested with different scenarios:
  • Atomic exchanges;
  • Security;
  • Validation;
  • Interaction of the Protocol with SQLite and PostgreSQL databases;
  • Consensus;
  • Modules for financial institutions;
  • Data exchange in the network;
  • Synchronization;
  • The monitoring system of balance;
  • Transactions that include trades;
  • API;
  • TkeyIndex;
  • TkeyConnect.
Documentation for the TkeyNet system will release on the website as well as reviews of the system TkeyNet will be published in the company’s blog.
Back-end TkeyNet developed in the C++ and C) programming languages, to improve performance, some of the code written in C.
The C programming language is the world’s fastest high-level programming language. It is called a high-level assembler, but unlike an assembler, code on it can be compile without changes on any device.
The specified stack is selected to meet the stringent requirements of the financial sector: enhanced security, scalability, and the ability of the system to work 24/7/365. The TkeyNet system is adapted to the world standards: ISO, ISIN.
TkeyNet supports the structured query language and interacts with flexible SQLite and PostgreSQL databases.
PostgreSQL complies with ANSI/ISO SQL standards, and unlike other DBMSs, it has object-oriented functionality, including full support for the ACID concept. An SQLite was selected to improve the speed and performance of operations. SQLite will also serve as an excellent solution for mobile applications that will be created based on TkeyNet.
PostgreSQL is the most advanced RDBMS, focusing primarily on full compliance with standards and extensibility.
During this period, we also completed work on a powerful API. The API is designed for organizations and developers to use the full power of TkeyNet in individual solutions. Software developers, whether mobile apps or local software, will get APIs and client libraries that will simplify the interaction of the corporate market with TkeyNet.
The API provides guaranteed availability, scalable volumes, and responds within milliseconds.

Test results: transaction and operation speed in TkeyNet

To date, testing shows excellent results on the speed of payments made via TkeyNet.
Last week’s results: unlike the first Protocol, where it took at least 10 minutes to validate a transaction, payment transactions in TkeyNet processed in 25 seconds without losing security properties. Performance improved by 2400% compared to Core 1.0

The block generation time in Core 1.0 is at least 10 minutes, and in TkeyNet — 25 seconds according to the test results.
If it took at least 10 minutes to confirm a block, and sometimes it took two or more hours, in TkeyNet developers achieved a stable indicator of 25 seconds without losing security properties.
To achieve our goal of launching the Protocol — we identify possible changes, theorize solutions, model proposals, and test our theories in practice. This process involves a lot of internal discussions and collaboration with external parties who provide feedback on the operation of a particular module, and the entire system as a whole.
Before the launch of TkeyNet, work will carry out to optimize and improve performance. The team plans to increase its performance indicators by 6000% compared to Core 1.0.

The Core 1.0 block generation time is 10 minutes. TkeyNet test network — 25 seconds. TkeyNet main network-up to 10 seconds.
To do this, we will work with individual modules and libraries of databases, transactions, and consensus. The goal for developers is to process payment transactions for up to 10 seconds at most.
The process secure in the logic of consensus, which solves a complex problem in a matter of seconds.

High throughput rates of the TkeyNet Protocol. B2B & B2C sectors.

To meet the needs of companies, startups, and corporations, — TkeyNet responds with fast processing of trades*.
Payment transactions — exchange of currency or shares, exchange operations, interbank settlements, etc.
For a better understanding, let’s analyze the obtained characteristics at the time of testing TkeyNet:
Results: 1,225,000 trades per block.

The scaling of the TkeyNet system

The TkeyNet system is easily scalable by increasing the RAM and CPU parameters. We have launched three nodes on powerful servers with the following characteristics:
  • CPU: 72 Core.
  • RAM: 144 Gb.
  • SSD: 120 Gb.
Transaction throughput increased 2.8 times to ≈3,430,000 transactions per block.

Vertical scaling

Unlike Bitcoin and other blockchain systems, where increasing the power of the miner’s hardware does not lead to an increase in network bandwidth.
Usually in such networks, increasing the power is a direct necessity, otherwise, transactions will not take place at all or will take hours, or even days. Because of what actually appears “manipulation of miners” and various types of network attacks.
On practice in such networks, increasing power is a direct necessity otherwise, transactions will not take place at all or will take hours or even days. Therefore of what appears “manipulation of miners” and various types of network attacks.
TkeyNet uses vertical scaling. With increasing node capacity, the throughput of the entire TkeyNet system increases. It turns out that regardless of the number and power of nodes, transactions will take place in 25 seconds, and with increasing power nodes — the number of processed transactions will grow.
As we said above, our developers are working to improve these indicators, where the block validation time will take no more than 10 seconds. Transactions will take place for 1 second to 10 seconds maximum. Also, this parameter significantly increases the volume of trades conducted via TkeyNet.

Front-end. Graphical user interface.
During August, the web products team continues working on secure wallets and a blockchain Explorer. The new software is under development, but it has already come a long way from layouts and graphic design and is ready to move to the stage of connecting the TkeyNet back-end with native products. If everything is in the final stage on the back-end side, then the client part (front-end*) needs time to complete debugging. We needed to design applications per best security practices.
\The Front-end developer creates the user interface.* Testing of blockchain applications is not much different from testing regular applications and resembles functional testing of a payment system. Test cases include checking the balance, fields, transaction statuses, and so on.
Also, we conduct continuous testing during development, taking into account the severity and scale of the TkeyNet system that will be used by organizations, corporations, and users, respectively. According to the results of testing and a meeting of the development team, the launch of TkeyNet is agreed for September 25–mid-October, possibly earlier.
Website — will be updated in October 2020, taking into account the volume of documentation, packaging all the meanings of the perfect new product TkeyNet. — updated earlier, before launching TkeyNet.
Also, to the upcoming launch of TkeyNet, the management decided to open a representative office of TKEY in the UK for the development of digital Banking and digitalization of assets.
Working with partners in the UK will focus on implementing TKEY’s corporate strategy and market solutions that meet customer needs, create new revenue sources, and provide opportunities for Corporations growth.
We create a great future for people by continuously improving our services and business products. All our actions are concentrate on becoming a leader in the market.
We also remind you that after the launch of TkeyNet, the start date of TKey trading will announce.
The fourth quarter will be hot, get ready!

Concerning BIT

This proposal gained 100 upvotes and 4 "reddit gold" in less than six hours. Are people actually seriously thinking this is a good idea or is this BTC's latest plan to destroying BCH or what?
I'm just about to go to bed so I can't monitor this thread but I personally can't believe what a terrible idea this is. Shouldn't check reddit right before bed, normally I'd just deal with it when I wake up but I can't ignore this one.
Since I don't have time to formulate this better I'll just repeat my two commets from that thread:
BCH is the ticker and bit is just slang for 100 satoshis. Calling it BIT and bits is just more confusing. I don't like this. Also don't put voting on twitter, some of us don't have twitter accounts.
Stepping away from having B for Bitcoin in the ticker is a bad, bad, BAD move.
Remember that Bitcoin Cash is Bitcoin.
Please don't forget that there's a chance we will get XBC in the ISO standard as well, if you have to call it something else just call it XBC. Changing it to BIT now is so bad, it's so bad that I kind of wonder if you really want what's best for Bitcoin Cash with this suggestion.
as well as
It's also a bad idea calling 1000000 bits 1 BIT as well as also calling 100 satoshis 1 bit. This would be mega confusing to anyone.
In speech: "yo mike, send me 2 bits" <-- Does he want 2 bits from Mike or 2 million bits?
In text: "yo mike, send me 2 bits" <-- Does he want 2 bits from Mike or 2 million bits? Was he just lazy and typed in lower case?
The fact that some people were so quick to jump on board with the idea of moving away from a ticker that has Bitcoin in it makes me worried. What's next, the logo doesn't fit in with the ticker BIT so maybe we should get rid of that tilting B, hm?
Bitcoin Cash is Bitcoin and I keep repeating again and again that it's not a good idea at all to differentiate from that fact too much. I don't even want the green color in the logo except for memes.
Today we have two ideas about how Bitcoin should proceed into the future:
Bitcoin (BTC) = Off-chain scaling, removal of signatures from the blockchain (SegWit) and reversible transactions.
Bitcoin (BCH) = On-chain scaling, the inclusion of both input and output script in the blockchain (just like how it's always been) and instant 0-conf transactions.
When one of these ideas have won and the other fork is dead and gone I want us to be able to just drop Cash from the name if we want to. BIT just makes people think it means "bit", not "Bitcoin Instant Transaction" or whatever. BCH makes people think the B stands for Bitcoin. Even if BIT made people think it meant something with Bitcoin it's still a bad idea since its confusing, a bit shouldn't mean both 100 million satoshis as well as be the slang for 100 satoshis.
TL;DR please don't be too quick to jump on this idea and please remember that Bitcoin Cash is Bitcoin

The thee pillars of Monero

Wikipedia has "pillars", foundational commitments which guide its develoments. Similarly, Monero has three pillars.
The three pillars of Monero are privacy, decentralization and scalability.
Now what does it means?


Monero is true electronic cash. With Monero, you can know that a transaction occured, but not whence, how much and whither, whilst it is getting increasingly easy to trace Bitcoin (mixers, tumblers… do not work). See this illustration on how it positions compared to Bitcoin and this animation on how it works. Monero is a cryptocurrency that is based on the CryptoNote protocol and reference code, and that seeks to provide absolute transactional privacy (fluffypony).
But Monero is more than a currency. Its official slogan is "secure, private, untraceable" for a reason. Other transactions than the monetary ones benefit from it. You may not want anyone to know you signed this contract. You may not want the forthcoming blockchain-powered internet of things cloud around you to be accessible by anyone, and this requires an opaque blockchain, that Monero provides.
We hired academic cryptographers to review and improve the security of Monero and started an external audit as well. Even Bitcoin developers and independent cryptographers (Andrew Poelstra/andytoshi, Gregory Maxwell, Nicolas Courtois) speak high of Monero and Cryptonote.
Finally, security is a chain as strong as its weakest link. What is privacy of the transaction worth if your IP is revealed? This is why we are teaming up with Privacy Solutions to have an i2p router implemented in Monero. IP obfuscation, amount obfuscation, recipient obfuscation, sender obfuscation.
May I remind everyone that privacy is more than drugs and illegality? Are you ready to give everyone (EVERYONE) read access to your bank account? Would your like your ex-wife, your son, your boss, your neigbour or (particularly if you are a company) your competitor to know how much money you have, where it comes from and what you doing with it, forever (and no, multiples addresses or mixers or tumblers just don't work)? Would you like your landlord to know that you just got some money, so s/he can raise the rent? Privacy is also making it possible for journalists fighting for the freedom of press to do their jobs when there are in a dictatorial (or not-so-dictatorial) country. This is also about not being incriminated because your money was tainted (two transactions before, it went from drug dealing, for instance).Countless studies showed that people behave differently when they know they might be watched.
As tacotime (a core team member) said back in April, when Monero was only one week old, Fuck the pump and dumps, we're here to create something with value that people can use.


Despite being decentralised at heart, cryptocurrencies are increasingly centralised. Webwallets, exchanges, pool mining and cloud mining, centralised seedings or masternodes… All of this is susceptible to attacks (both technical or legal - remember that "legal" doesn't necessarily means "legitimate"). Whilst Monero is decentralised mixing.
By contrast, we are trying hard to keep Monero decentralised. Our domain names for the most parts are meant to be resistant to such attacks ( on choosing domain names and registrars). The core team is composed of both public faces (myself and Riccardo Spagni/fluffypony) and private faces (the other core team members) located on various continents with widely different timezones, making sure that core devs are avaialble 24/7. This extends to technology too. When implementing something, we keep in mind how it will affect decentralisation. We recently released the first Monero torrent and we also created an open standard for simpler sending of cryptocurrencies, OpenAlias.
The smart mining forthcoming feature will allow transparent CPU mining on your own computer, far from the de facto centralisation of mining farms and pool mining. We intend to pursue Satoshi's original vision of a true p2p currency. "Get millions of users doing that and it will drive down the value of mining to where neither botnets nor professional/industrial miners will bother, and Satoshi's original vision of a true p2p currency will be realized." (smooth).


Monero is meant to stay. Long. This means it must be able to be adopted by anyone, that anyone can use it. Open-source is a given and smart mining participates of it too. But beyond this, we chose a currency code a.ka. ticker symbol (XMR) that adheres to the international monetary standard ISO 4217. We are doing our best to follow technological best practices. Recently, we worked with Kitware to have our Cmake tool adhere to the best practices and we will soon transition to semantic versioning ( Similarly, the block time, mixin count… are designed (and sometimes redesigned) with long-term scalability in mind.
More importantly maybe, Monero doesn't suffer from some of the inherent flaws of many orther cryptocurrencies. Monero is fair-launched and doesn't have a 1 MB blocksize which limits the ultimate amount of transaction per day. Today, it doesn't matter much, but tomorrow when Monero will be much more popular, this will be instrumental in ensuring that Monero can continue to grow - this is the whole point of scalability: it may not matter today, but it does for tomorrow when it will be so hard to change it.
The same consideration are given to the emission curve. We believe (and we are not the only ones), that relying only on transaction fees won't be enough of an incentive for miners (remember: the core of the blockchain is to rely on an economic incentive, because it is not possible to solve the Byzantine Generals' problem with math alone). This is why Monero implements a "tail emission" that will kick off once the main emission is over, in less than eight years.
Scalability is not only about technology. It also about making sure that everyone gets their side of the bargain or else it will be rejected. That's why Monero is also optionally transparent. This means that, on a completely voluntary basis, one can give read access to someone else. Quoting fluffypony on reddit: "A view key can be used to reveal all transactions for an account. This means that companies could still be audited, charities could make their accounts publicly visible, and parents could see what their kids are spending the money on. Additionally, details of a transaction can be revealed via a similar mechanism on a per-transaction basis."
This is also to increase legitimacy that the Monero Economy Workgroup (disclaimer: I am an executive of the MEW) was created (what is MEW? - join MEW). The MEW takes decision (that, granted, the core team is not bound to accept, but refusing a widely adopted decision would cause turmoil) and since the MEW is meant to represent the will of most holders, it will increase legitimacy: something decided by the MEW is something most holders are willing to do. The debate on the emission curve is a perfect example: the MEW unanimously decided to not change the emission curve, and confidence went back immediately. Consistent confidence is part of scalability.
Security, decentralization, scalability. These are the three pillars of Monero. The vision of Monero is to be as future-proof as possible.

As a long time, but small volume holder of Bitcoin: These are some problems Bitcoin has that stops major acception.

Since 2011 I have been interested in Bitcoin, been mining, using it, etc and lately got back in the game after selling it all for $2 a piece (don't ask).
Having told and introduced some For "Common folk" these are some of my experiences.
Just my 2 (mBTC)cents :)
Edit standardization is the key:

Is it time to apply for ISO 4217 code for BTC?

Does anyone know what are the conditions currency has to meet to be recognized by ISO for ISO 4217? I've just asked SIX Interbank Clearing Ltd the same question, waiting for their reply...
EDIT: It turns out that there is already petition on for this, please sign it here.

Alternate Proposal - Let's change our ticker AND switch to bits, a slow natural approach

If you haven't read the post made by singularity, it makes some good points about switching the denomination to bits, however, I think in it's current form it will be very difficult to get the entire community on board. After all, we've been down this path many times before.
Proposal - Makes 'bits' (1 millionth BCH) the standard denomination and 'BIT' the ticker
Proposal Summary
Some exchanges may choose to keep BCH to represent the whole base unit, but I propose we use XCB (Bitcoin) Cash Bits as the major unit and satoshi's as the "minor" currency unit which is 1/100 of the major unit used for commerce as defined by ISO 4217.
  1. Bitcoin Cash (BCH) - non-standard whole units (Similar to non-standard GLD used for gold XAU on exchanges)
  2. (Bitcoin) Cash Bits (XCB) - bits, as defined by ISO 4217 with "exponent" value of satoshi
What is ISO 4217?
In short ISO 4217 is a currency designator used in banking and business globally. Codes beginning in X are designated for "supranational" currencies which do not belong to a specific country. Major currency units allow an exponent to be used to represent the minor currency unit. In our case, I'm using the gold example to define the major unit (ie 1XAU = 1 troy ounce of Gold) which would be 1XCB = 1 cash bit of Bitcoin Cash and the USD example to define the exponent or minor unit (ie USD United States Dollar = 1 dollar with minor unit of 1/100 or 100 cents) which would be XCB (Bitcoin) Cash Bit = 1 bit with a minor unit of 1/100 or 100 satoshi's.
Why should we add XCB as a new symbol?
For starters, the symbol XCB is an available code in the active list of official ISO 4217 currency names. While Bitcoin Core is now a store of value which will be used as a settlement layer for the Lightning Network, Bitcoin Cash is a currency that we are pushing to use for global commerce. If it is to be used in commerce around the world, it is inevitable that the current symbol WILL HAVE TO CHANGE to fit the formatting of the ISO 4217 standard. Once the first country recognizes XCB it as a currency, it should be on it's way to official approval.
What are the next steps?
  1. As singularity pointed out, the most important step is gaining community support and recognition from
  2. All other steps are clearly laid out in the Proposal by singularity
I think this approach can happen more slowly over time as there is a natural progression to use bits and we can keep both BCH and XCB. Exchanges and wallets can choose to keep the non-standard symbol BCH to represent base unit and slowly begin adding and/or moving to XCB bits to represent the standardized ticker used for commerce. It doesn't have to happen overnight and I think it will cause the least amount of confusion. I feel like it may be a much bigger battle to switch to BITS as a ticker with a 1,000,000/1 display and will likely end up never moving forward.
So, in summary:
  1. 1 Bitcoin Cash BCH = 1,000,000 XCB bits (major unit)
  2. 1 XCB bit = 100 satoshi's (minor unit)
Please share your opinions on this proposal, thanks!
EDIT:. I don’t think I’ve made it clear. I’m not actually suggesting we change our existing symbol BCH. I’m proposing we add a new symbol XCB that follows the ISO standards which would be used by wallets for commerce.

What is Peercoin?
Peercoin (Project name: PPCoin) is a relatively new cryptocurrency (August 19, 2012) which like all other major cryptocurrencies is based on Bitcoin.
Peercoin is currently the cryptocurrency with the greatest number of innovations. The key difference being that it implements a proof-of-stake system in place of the proof-of-work system. This system is designed not only to make Peercoin truly energy efficient in the long run, but also to dramatically raise the cost of a 51 percent attack, and to facilitate a steady predictable inflation rate of one percent per year.
Peercoin is what you'll likely call it in daily speech. It's easily pronounced and looks good in text.
PPCoin is the official name of the project and coin.
PPC is its currency code and an acronym for Peer-to-Peer Coin.
Cryptocurrency is a currency relying on cryptography for authenticity.
How do I buy Peercoins?
The most common way is to buy Bitcoins and trade them for Peercoins at an exchange. Popular exchanges are listed in the sidebar.

    Note: Until the wallet has synchronised with the network, you may not see coins sent to your address.
  3. Encrypt and backup the wallet. (optional, but strongly recommended!)
How many Peercoins will exist?
Simple explanation.
Was Peercoin premined?
No, the first block was not mined until 18:19:16 UTC, whereas the coin software was released to the public at 17:57:38 UTC.
Additionally, Peercoin has had arguably one of the most fair launches of any cryptocurrency to date.
