La idea es verificar la existencia y unicidad de esa persona física. Si no fuera así, cualquier persona podría pedir monedas más de una vez y en nombre de una persona existente o no.

Me alegra preanunciar TangoCoin (TNG, ₮) la primera criptomoneda argentina, diseñada para la mercado interno argentino.

Intentaré explicar porque esta moneda es diferente al resto de las monedas existentes y porque sería útil para la economía argentina.

Por qué TangoCoin es diferente?
La mitad de las monedas se distribuirán equitativamente a toda la población argentina. El resto de las monedas serán generadas (minadas).

Por qué en Argentina?
Argentina es un país con una muy alta tasa de inflación (entre 25 y 30% anual) y su moneda local, peso (ARS) se devalúa diariamente (http://finance.yahoo.com/echarts?s=ARSUSD=X#symbol=;range=5y), siendo muy difícil ahorrar o invertir en pesos. La velocidad de circulación monetaria es muy alta y las grandes transacciones actualmente son realizadas en dólares.

Quién puede solicitar monedas gratuitamente?
Solo las personas físicas con DNI argentino.

Cómo van a ser distribuídas las monedas?
Cada ciudadano deberá publicar su dirección tangocoin firmada con un certificado emitido por cualquier autoridad certificante aprobada por ACAP (https://pki.jgm.gov.ar/app/) y/o ACRaiz (https://www.acraiz.gob.ar/) o cualquier otra autoridad futura. Tras verificar la firma digital, 1000 TNG serán transferidos de la cuenta colectiva a la dirección tangocoin informada por el ciudadano. Se intentará realizar este procedimiento lo más transparente posible. Como aún no todos poseen un certificado digital, no es posible distribuir monedas no solicitadas todavía.

Cómo se puede auditar la cuenta colectiva?
La cuenta colectiva comenzará con un saldo de 40 mil millones de monedas. Cada transacción saliente será verificable que haya sido transferida a una dirección tangocoin firmada digitalmente (ver arriba), verificándose también la unicidad de la firma.

Qué sucede con los intereses de la cuenta colectiva?
Se distribuirán también. Por lo tanto, quizás sea posible distribuir a la población futura.

Puede alguien fuera de Argentina minar o usar esta moneda?
Por supuesto. No puede prohibirse.

Cuál es la fecha de lanzamiento?
9 de marzo de 2014.
9 de junio de 2014.

Aspectos técnicos:

Total de monedas: 80 mil millones TNG (más 1% de interés anual).
Algoritmo: scrypt (quizás scrypt-jane).
Preminado: 50% a una cuenta colectiva. 1000 TNG distríbuídos a cada argentino (población aprox. 40 millones)
Emisión posterior:
1er año: 10 mil millones
2do-6to años: 5 mil millones
Últimos 5 mil millones: 2.5 mil millones, dividiendo por 2 cada año.
Interés PoS: 1% anual.

Se invita a cualquiera que desee colaborar con el proyecto. Buscamos tanto programadores como interesados en difundir la moneda previo y durante el lanzamiento.

DNI is an ID number. Each citizen has a unique ID number and it is also used for elections. If the government wants to create fake DNI numbers, then they have already another 'better' reason to do that!
I believe there are not fake DNI numbers at all.

Hi! Thanks!
ACAP/ACRaiz are the best way I know by now. We could think alternative ways to add in the future.
I have just uploaded the source code to github if you want to see it, if you want github write access let me know. There are many changes to make but it's a start.

Hi! I know we used to have many alt currencies in the past.
Maybe we'll need a nice wiki for normal people to understand the basics. Could you do that?

Thanks!

I hope so!

I will try to make this as transparent as possible. If you have any ideas to do that, i would appreciate that. It is very easy to verify digital signatures so it is possible to audit the escrow address permanently. Maybe I can release a webpage to do that too.

Thanks!
I know it would be better to distribute to everyone in the world. But it is technically not possible to verify uniqueness.
Also, domestic currencies are more common than worldwide accepted currencies. So, I think it is better to replicate that, but well distributed!

I'm glad to pre-announce TangoCoin (TNG, ₮), the first Argentinian cryptocurrency, designed for the argentinian domestic economy.

I will try to explain why this coin is different to all other current coins and why it would be useful to the argentinian economy.

Why is TangoCoin different?
Half of the coins will be premined and distributed equally to all the population. The remaining coins will be mined by PoW+PoS.

Why Argentina?
Argentina currently is a country with very high inflation rate (25-30% y/y) and its domestic currency, peso (ARS), is devaluated on a daily basis (http://finance.yahoo.com/echarts?s=ARSUSD=X#symbol=;range=5y) so it's very hard to save or invest in pesos. The velocity of the money is very high and all big transactions (above 10,000 USD) are currently paid in american dollars.

Who will be able to ask for free coins?
Only natural persons who have a unique ID number of Argentina (DNI).

How will the coins be distributed to the population?
Each citizen will have to publish his tangocoin address signed with any certificate issued by any certificate authority approved by ACAP (https://pki.jgm.gov.ar/app/) and/or ACRaiz (https://www.acraiz.gob.ar/) or any future authority. After verifying the signature, 1000 TNG would be transferred from the escrow address to the citizen's tangocoin address. I will try to make this as transparent as possible (any ideas here are welcomed). However as not everybody already has a digital certificate, it is not possible to distribute unasked coins yet.

How can I audit the escrow address?
The escrow address will start with a 40 billion coins balance. Each transaction from that address will be verifiable that it was transferred to a signed tangocoin address (see above), verifying also the signature's uniqueness (so it wasn't asked twice).

What about interests in the escrow premined address?
It will be distributed too, so maybe it would be possible to distribute coins to the unborn future population too.

Can someone outside Argentina mine or use this coin?
Of course, I cannot forbid it.

When will it be released?
March 9th, 2014. (2014-03-09 01:00 GMT)
June 9th, 2014. (2014-06-09 01:00 GMT)


Technical specs:

Total coins: 80 billions TNG (plus 1% interest PoS).
Algo: scrypt (maybe scrpyt-jane)
Premined: 50%. Distributed: 1000 coins to each argentinian (current population: 40 million). None for me nor any collaborator, no giveaways.
Minitng PoW:
    1st year: 10 billions
    2nd-6th years: 5 billions yearly
    Last 5 billion coins: 2.5 billions, halving every year.
PoS interest: 1% yearly.
Blocks every 1 minute.
Difficulty adjusting every day.
