Re: [ANN] B&C Exchange – A decentralized exchange - *** LIVE AUCTION ***

Are we going to repeat the system where Blockcredits custodians will try to elevate grants to start operating in  small and untrustworthy exchanges and the Shareholders will cover the losses after the unavoidables hacks/adminrunnings?

BlockShares holders will have full control over which exchanges its custodians sell on since there is no centralized control by its developers. This means that shareholders could conceivably only elect BKC custodians that operate directly on B&C Exchange's safe platform.

Ok, that's a good point I didn't think about and a serious difference with the Nubits/Nushares system.

It is also worth pointing out that "mutualizing all the losses that custodians are going to suffer" is outside the scope of B&C Exchange operations because BlockCredits will not be supported at any specific price level. They will simply be sold for 1.00 USD. In the event that BKC are stolen from a custodian operating on a centralized exchange, they would likely be dumped on other exchanges for fractions of a dollar. Shareholders would only suffer lost revenue from the lack of new BKC being sold during the time the stolen BKC were dumped. For this reason, it is also likely that shareholders will prefer granting small batches of BKC to a custodian that will last for a week or two, rather than providing a year-long supply of BKC up front. Continuous replenishment of BKC to custodians is very easy in our design.

Aren't custodians risking bitcoins too in the pair BKC/BTC offered in the exchange? If so, custodians could lose both and, as hackings/adminrunnings occur, less and less custodians will be willing to request a grant. Something similar happened in nubits/nushares and, the only way to provide confidence, was to compensate custodians diluting Nushare holders. Why can't this happen here?

The design of B&C Exchange will protect networks like NuBits from the unpredictable and devastating failings of centralized exchanges. You are right that NuShareholders have not recently voted to give themselves a dividend as they work to recover from the exchange hackings of February. The dividend mechanism has been used in the past however and is fully functional.

It's curious. I'm, at the same time, Nushareholder and criticizing all these subjects but, in my opinion, transparency in this development must be fundamental. I hope you understand me.

Ok, you say "This mechanism is currently being used with great success in the NuBits and NuShares network." Well, I'm a three months Nushare holder in your six months old Nubits/Nushares system and didn't see in all this time a single dime in dividends. All I have seen is nubits custodians losing funds in hacked/adminrunnered exchanges and Nushares holders being diluted trying to compensate the custodians lost.

Are we going to repeat the system where Blockcredits custodians will try to elevate grants to start operating in  small and untrustworthy exchanges while Shareholders are covering the losses after the unavoidables hacks/adminrunnings?

I'm sorry being so negative, but I think shareholders will find themselves pretty soon underwater as happened in nubits/nushares because, probably, it's less dangerous to exchange quickly in some big centralized sites (like shapeshift.io) than mutualizing all the inevitable losses that custodians are going to suffer in the small and untrustworthy exchanges that will agree to accept the BKC/BTC trading pair.

Problem [flawlessly solved] with Shapeshift.io exchange
by
Polvos
on 17/04/2015, 17:20:32 UTC
Well, after many years in the Bitcoin world, I made my first mistake in an exchange some days ago. In Shapeshift.io exactly.

Things went more or less in this way:

After 6 large nubits dumps there, seems I depleted all their market depth available so, in the seventh and last, I dumped 843 nubits and, naively, didn't cheked the exchange rate. I ended up paying 843 nubits (1 nubit = 1$) for barely 1 BTC. The emails I interchanged with Shapeshift went as follows:

Me:

Quote
Dear Sir/Madam:

Just some minutes ago I used your shapeshift.io service (as I have used many times recently) in order to buy some BTC with nubits. Today I made 7 transactions of that kind in your service.

But I think I had a problem with the last one. I'm talking about the 843 nubits transaction that landed in your Bxxxxxxxxxxxxxxxxxx nubit direction. After 6 perfectly smooth transactions, this one ended up with a really huge slippage that I didn't realize and I naively continued with the transaction.

For the 843 nubits I sent you, you sent me barely 1 BTC to my bitcoin address. Is it correct? Did you make a mistake with the huge slippage or do I have to accept the deal your platform offered me?

I'm sorry for my bad english, but It's not my main language.

Shapeshift response (in less than 24 hours):

Quote
Thanks for contacting us. We're looking into this when our developer is
available and I'll send you an update then.

Please always make sure to check the exchange rate before you send the
coins, because the exchange rate can move. If you were doing lots of big
transactions, it's possible that you cleared out the market depth that
was available.

Will get back to you soon, thanks.

Another Shapeshift response (again, less than 24 hours from my last email):

Quote
I checked this out, we will send you some more BTC to cover the difference.

Can you send me your BTC address?

Kind regards,
Beorn

My response:

Quote
Of course. Please, send the bitcoins to the following address:

1xxxxxxxxxxxxxxxxxx

Thank you

Shapeshit response (less than 24 hour after my last email):

Quote

2.63 BTC has now been sent to you to cover the difference.

It appears there are some liquidity bots that the Nubits team uses to
maintain the price on exchanges. These bots do weird things
occasionally, and I think your order went through when the bots had
failed to set the price correctly.

So, in the future, please double check the exchange rate each time you
send an order through and we should be able to avoid this issue.

Thanks for being a customer and please let us know if there is anything
else we can help you  with.

Kind regards,
Beorn


My last email to them:

Quote
Ok, thank you very much. Next time I will check the price.

Now, I inform you that it's my intention to post in bitcointalk about the mistake I made not checking the rate in your service, the flawlessly and fast response you gave me and the trust you very well deserve. I'm really proud to be your customer.


Well, draw your own conclussions, but I wanted to write my experience here because I'm tired to read only bad experiences with exchangers.

My conclussions:

- Always check the exchange rate. ALWAYS.
- They deserve my trust.
- Their customer support is really good.

¿Por qué he de pagar por ethereum cuando puedo tener perfectamente gratis y con las mismas cualidades aethereum?

https://bitcointalk.org/index.php?topic=563925.0

Cuando comenzó el tema de los spin-offs de Bitcoin enseguida uno podía darse cuenta de que Bitcoin terminaría fagocitando a todas las altcoins basadas en proof of work símplemente clonando las cadenas (con sus nuevas cualidades) y repartiendo las monedas proporcionalmente entre los poseedores de bitcoins en un momento determinado (el del inicio del spin-off).

Así que, al día siguiente de aparecer ethereum, surgirá un spin-off de Bitcoin llamado aethereum, que será un clon del primero con algunas leves modificaciones que permitirán distribuir sus nuevas unidades monetarias, los aethers, entre los poseedores de bitcoins en ese instante.

Como ambas criptomonedas tendrán idénticas cualidades...¿dónde habrá más usuarios, o sea, nodos activos? en aethereum. ¿Dónde habrá más creadores de contenido/aplicaciones? en aethereum. ¿Dónde habrá más desarrolladores? en aethereum. ¿Dónde habrá más gente aportando su hardware para asegurar el sistema PoW que ejecuta los scripts? en aethereum.

Lo siento por los que habéis comprado en la IPO de ethereum, pero cuando se habló con la aparición de la idea de los spin-offs de que Bitcoin terminaría convirtiéndose en un gigantesco agujero negro, creo que los desarrolladores se referían precisamente a este tipo de casos.

¿Cuánto creéis que les puede costar a la constelación de desarrolladores de Bitcoin el modificar el código de ethereum ysacar la cadena paralela aethereum cuya distribución inicial del bloque génesis sea, en lugar de repartir las monedas entre los aportadores iniciales, hacerlo entre los ya poseedores de Bitcoin y ceñir la inflación futura a la que va a existir en la cadena de Bitcoin? Ya os lo digo yo: cambiar cuatro lineas de código, no creo que muchas más.

A partir de ahí, cualquier idea, cualquier desarrollo, cualquier nuevo script, cualquier autonomous corporation, etc podrá ser perfectamente clonado tanto en ethereum como en aethereum, para desesperación de su autor. Será inevitable.

Así que yo, a igualdad de cualidades que puedan ofrecer ambas criptomonedas (ethereum o aethereum), prefiero esperar y decidirme por entrar en aquella que pueda ofrecer más seguridad, bien en forma de nodos de la red (para prevenir un sybil attack) o bien en forma de potencia de cálculo en el sistema PoW (que prevendría un ataque 51%). Y, gracias a la gratuidad en el acceso inicial, mucho me temo que será aethereum la que podrá aportar mayor seguridad, aspecto de extremada importancia en el mundillo de las criptomonedas.

Como bien dice el sr Dickinson "la nueva ley que escribió sólo reconoce lo que ya está sucediendo". Con o sin esta ley el comercio con btc estaba y seguirá sucediendo.

Efectivamente, esa es la mejor frase de todo el artículo. Dickinson símplemente se limita a articular legalmente lo que la gente ya está haciendo de forma habitual.

However unlike its predecessor Peercoin, NXT introduces the idea of randomness in the selection of which stakeholder has the right to author a block

Esto ya está en Peercoin. Seguramente la implementación es un poco diferente, pero en PPC también depende del azar cual de los "stakeholders" forja un bloque.

Puede ser, pero el sistema de transparent forging es tan ingenioso que, aun manteniendo ese carácter de azar a la hora de forjar un bloque, es lo suficientememente previsible como para poder "predecir" quién minará determinado bloque y focalizar las transacciones hacia él para aliviar el tráfico de la red y así poder ofrecer la posibilidad de alcanzar un límite de transacciones que la red podrá gestionar mucho mayor.

Re: Decentralised trading (not what NXT/Ethereum or anyone is doing at the moment)
by
Polvos
on 13/02/2014, 14:57:30 UTC
This "decentralized trading" idea can only work with digital assets (e.g. blinded Bitcoins...), not fiat money. There is no way to "digitalize" a dollar bill without introducing a third parts (called bank, escrower, gateway, exchange...).

Here is a solution using collateral to build a system for trust-less fiat-btc trading:
https://bitcointalk.org/index.php?topic=462236
The bank transfer(s) can be reversed after the BTC are released. Alice Will steal Eve's bank data, send 1k USD to Bob, pocket the BTC and then Eve gets Bob in trouble. This happens often enough on both localbitcoins and bitcoins.de already right now (since that's the exact same system these are operating under).

The bank transfer network is the third party in that scheme and it sucks compared to Ripple for example, since transactions between banks are reversible. It would only work with cash-in-mail and even then you need to trust the postal services.

Also if BTC prices fall more than 10% until the BTC are sold, Bob is better off never releasing the coins. Using this system is like shorting BTC on reversible bank transfers no less. Good luck with that.

I agree, but with the Nash equilibrium solution posted here, you don't need to trust the banking system. You can perfectly send cash money by snail-mail.

This is good but one obstacle in the USA is how to get funds into the other person's bank account.  Chase is already making it so you are not able to deposit cash into someone else's account, and other banks are likely to follow.

With this Nash equilibrium solution you can even send money by snail-mail. You don't need to trust the banking system.
