STM32f2 is a good chipset. Five buttons is perfect. You need anodized aluminum cases. The plastic trezor case does not have a quality feel.

Have you seen our brain wallet sigil spec? This is a graphical representation of deterministic wallet seeds, that has an elegant hardware implementation.

We think this is better than Trezor. Its very simple too. A OLED display ($5), a $2 32 bit arm processor and five buttons. We want a hardware wallet implementing this standard.

There is a square with 4 quadrant. Each quadrant has a 3x3 grid, with 16 states per element. The advantage is that the format can be written on paper, can be inputted onto hardware device or can be remembered easily compared to a 64 bit hex string. There is also built-in human check-able error correction to prevent transcription errors.

update

Working on migration to new API now.

The new wallet API will separate out checking balances, getting unspent outputs and injection transactions.
- the node is physically separated by an API layer from the private keys
- this makes hardware wallets easier
- this makes it easier to add Bitcoin, Dogecoin and Litecoin into the Skycoin wallet. Every coin can go through a common API interface.
- this means wallets can be like blockchain.info, but completely local. There is no risk of javascript injection or anyone stealing wallet through web-browser.
- nodes are able to query balances, create/sign transactions and inject transactions without running full blockchain. They can use remote nodes through same interface as local nodes.
- dark wallets will not work without a full transaction history. There is no way to do darkwallets in Skycoin with a thin client. Generating a shared address with recipient public key requires a full copy of the blockchain.

This is an amplitude modulated software defined radio for the whitespace band. 100 Mhz to 700 Mhz carrier. This is the most simple type of radio possible. Its pretty trivial.

Can you hook up an FPGA, maybe one on an ARM development board to an CPLD. We need to take a 600 Mhz to 700 Mhz carrier and amplitude modulate it (multiply the amplitude of the carrier by a value, which changes and can be set). The CPLD needs to implement a Digital to Analog (DAC) converter and then amplitude modulate the carrier. Then this gets amplified and is connected to antenna.

Then we need a Analog to Digital (ADC) implemented on the CPLD for receiving radio on other end. Changing the ADC/DAC 20 million times per second with a 4 to 8 bit ADC/DAC resolution is sufficient for now. A fulll 300 Mhz is ideal, but may not be possible without skillful pipelining.

For example. On beagleboard black, there are ADC/DAC units on the real time units. We can set output to "8" and then voltage level 8 comes out, we feed that into the gate on the amplifier. Then a ~50 Mhz HAM frequency carrier comes in to amplifier and is amplified an amount depending on voltage of gate. Then we change the 8 to a 40. With the real time unit, we can do that ~1 million times per second. Then the value gets amplified, fed into antenna and we are transmitting a sin wave with height 8. We have an array of bytes, one byte is read in a at a time and sets the output  value of the DAC, which updates 1 million symbols/second. So we are signaling with radio. This is same thing, except we want the ADC/DAC in the CLPD, so we can do hundreds of MHz and later modulation of the carrier twice per Hz, with changes applied at the zero crossing.

Eventually we want modulation at two symbols per Hz, so 1.4 billion times per second for 700 Mhz carrier (one output for positive part of sin phase and one for the negative phase) with 8 bit resolution for DAC output and +8 bit for ADC reception (or whatever is feasible). The value change for the analog output should occur at the zero crossing of the carrier, to prevent snapping. This will probably require moving the CPLD to ASIC to operate at this baud rate.

At 700 Mhz, with two 8-bit symbols per Hz we are at 11.2 Gb/s for maximum rate (two 8 bit symbols, 700 million times per second). That is the data rate for CPLD to the FPGA. Because of noise, antenna ringing and requirement for forward error correction (100 bits may have to be sent for each received bit), the data throughput may be significantly less than the symbol baud rate. The ASIC version may need a hardware IO protocol (PCIe or other) to interface between the CLPC/ASIC and FPGA at this rate. At those data rates the forwards error correction will need to be implemented in the FPGA, but CLPC prototype may be low enough baud rate for this to be performed in software. We are assuming that directional antennas are used and that the target signal is the loudest signal received, which significantly reduces the resolution requirements on the ADC for reception. Very simple circuit. We are not sure if phase locking or ability to set phase offset is a requirement.

Eventually the FPGA and CPLD, frequency generation and amplifier should be on a single PCB. The FPGA should implement Unipro so we can plug it in into an ARA baseboard. This is the end-target, but prototyping with ARM+FPGA dev board may be easier, or you may have better solution. Alternatively, the first device could be an CLPD + FPGA with a USB interface. Whatever is easier, you probably have a USB FPGA core already. The control board or system should use a Debian linux.

We can provide software in C for an initial forward error correction code. This can be on CPU initially, but move to FPGA is later required to handle full data rates (which may not be hit by the CPLD).

We understand the CPLD can go to 300 Mhz, so 300 MHz modulation of the carrier wave may possible without going to ASICs. Higher frequencies may be possible by including multiple copies of the circuit, with clock skews. For instance, having one DAC for the positive phase and  one for the negative phase. A simple CPLD design should be able to achieve a symbol rate of a few dozen Mhz. The ADC needs a floor and max and adjustment to bring the signal within range. This needs to be changed seldom (assume as most 1000 times per second).

I would get it working with a 1-bit or 2-bit ADC/DAC block on the CPLD and then go from there. Alternatively, if there is a very cheap ADC/DAC chip that can handle these ranges or 3 samples per second at 1.4 Ghz, we could use that and wire it into the FPGA. I have feeling that DAC/ADCs chip rated at the required sampling rate are $100 and that getting board down to $20 will require a degree of ASIC integration in the analog frontend.

So the objective here, is to get a lower frequency prototype working in CPLD
- to reduce risk for doing MOSIS/ASIC prototype that can handle full rate and higher resolution in the ADC/DAC. The symbol baud rate for the ASIC version may require integrated hardware IO pin for interface to FPGA, but is otherwise the same.
- then if that works, get a few wafers on an older process
- to have something working early, so that we can distribute dev boards and start on software development and prototyping, antenna development

That is first generation. Second generation
- multiple DAC/ADCs for running multiple antennas
- digital delay line (same signal from each output, but with defined phase shift and amplitude change) so that we can do phased array
- low frequency control or modulation of phase shift (to allow phase locking, reduce interference between transmitters)
- two antennas can resolve or filter on direction from phase shift of signal received by two antennas at a separation.
- N antennas elements each making independent reading of same signal, helps reduce noise floor.

Go learn Verilog, go get a CPLD and implement direct digital synthesis and go implement a SDR and then put it on github.

Are our BTCs in danger if the plugin is not open sourced? I am not too technical, but I guess that we could loose our BTCs (if the trezor team would decide to scam, not that they will but speaking hypothetically) only while singing transactions if the plugin was to be malicious (by changing addresses etc..). Since trezor signs transactions locally I see this as the only possible scenario, am I right?

Yeah this makes a lot of sense. To be honest, i was just a total mess total my nerves were wrecked hoping everyone would be honoring their words. But everyone was totally punctual, I'm meeting one of the members in person in a couple weeks and could not be happier with Bays performance and that of the other members. So we shall see how it plays out. We are making an operating budget and dont forget, we need that buy wall too. So its just a matter of being pragmatic. How many devs can we prepare in time, who works on what. Most likely I'm going to draw out an entire plan of how we structure the next month and what tasks to delegate.

Blackcoin? How is that relevant?

Ubuntu does not provide static versions of these libraries. Please read instructions how to build using Docker.

What courier is the Trezor shipped through?

I received a tracking number, but it doesn't show up on any of the following courier's sites: USPS, Canada Post, DHL, UPS or Purolator.

EDIT: It appears it was shipped through a Czech Republic courier. Website: https://www.postaonline.cz/

Ya. We could have done the IPO in January. I cant remember what stopped the IPO from happening.

The IPO does not mean its done, or even that it works. It just means the coin is trading publicly. If Skycoin succeeds, it will spawn fifty clone-coins before we even have the software working.

Bitcoin took the form it did (a single large, global world internet currency) because of mining. Only the coin with the most hashing power can be secure. Bitcoin ended up being radically different than the intention many people had for cryptocurrencies. Bitcoin is still a stepping stone to the next stage. Bitcoin is priming the pump. Almost all the mined coins are pump and dumps. A very few of them are very innovative however.

There are groups of people of various sizes and they want to start their own digital currencies. They have looked at Bitcoin, but they cannot afford enough mining equipment to make it work. As soon as mining is eliminated and unnecessary, the landscape will change. You will see a lot of "community currencies", towns, websites and smaller groups like American Indians on reservations issuing their own coins. Every private Bitorrent tracker will have their own coin. You may even see companies begin to issues currencies to customers and suppliers.

These coins will be more local and relevant. Most of them will fail, but a few will make it. These coins are going to be inter-operable from day one. It wont matter if a merchant accepts Dogecoin or Litecoin or Bitcoin, whatever you have in your wallet will convert over at the spot price and users will not even think about it. Merchants may choose to hold profits in one currency and users may have a completely different set of currencies they hold. It will be a two-sided market.

There will not be a "litecoin ATM" or a "Bitcoin ATM", it will just be called an ATM. As routine transactions become automated, income, debt and credit will start to creep in. Very few people right now have income in Bitcoin and the things you can buy with Bitcoin are still limited, but that will change as we go into stage two.

Stage three will probably be an attack on the idea of currency itself. Bitcoin is a small technical achievement. Regulators can handle it. Libertarians were screaming and making scary noises about how "revolutionary" and "threatening" Bitcoin was and the regulators calmed down when they realized that Bitcoin is same as cash or gold. Its just another commodity. Bitcoin is not any more "threatening" than someone trading a gold ETF back and forth between two accounts. Governments will just put some reporting requirements on it and make sure they get their tax money when you buy anything.

Stage three is already laying the technical foundation for computer mediated systems of exchange that are radically and conceptually different than anything that has existed. Look at Ripplepay and the idea that money itself is just credit and debt. In Ripplepay money transcends its origin as a commodity and becomes a system of contracts and relations in a network. The role of money as a commodity inevitably becomes separated from the role of money as a unit of account.

Technology is enabling the creation of new objects, with new properties and relations that no previous object had. To own a gold bar is to possess it. To transfer ownership you physical move the bar into the possession of someone. In Bitcoin, "ownership" was transformed from its physical form, to knowledge. The "owner" of the Bitcoin is the one who "knows" the private key to authorize transfer of the Bitcoin.

If a coin is secured by two public keys, held by two parties and one party publishes the private key for their public key, the other person and now only that person can authorize the transfer of the coins. The "ownership" has changed without the coin having even moved. Merely the state of knowledge in the world has changed, without even touching the blockchain and yet the Bitcoin has changed hands.

Bitcoin would need a 2 trillion dollar marketcap to even represent one percentage point of global wealth (the foundation of security provided by the mining process will be severely threatened before we get there) . The end game is not 2 million dollar clone-coin pump and dumps. It is systems of exchange that will represent single or double percentage points of global assets and financial wealth. The correct investment horizon is probably five to twenty years.  In the excitement of two new coins launching every day, people are forgetting how far off the end goal is and underestimate the sacrifices required to get there.

这个问题，问的很有建设性，它是这样的，并不能说这些服务全部都是中心化过运营，这些服务功能，被集成了每一个钱包中，任何用户都可以架设自己收费服务器，实际上，我们也是鼓励用户自由架设服务器，无论是收费的还是免费的，但是在现在我们才开始进行推广，在这个阶段，由于用户并不了解我们，所以我们以身事先，架设了一些服务器供大家来体验它，以此来促进网络发展。可喜的是，目前我们已经发现，有一些积极的用户也架设了服务器，预计在不远的将来，网络状大了，当我们币拥有价值时，会有更多人参与架设服务器，这些服务器都是以分布式的方式运行，他们实际上也是一个个钱包节点。

在这里，我想说的是，Vpncoin不是一款单纯的虚拟币，由于它集成了网站架设，VPN代理及P2P等一些实用性的面向社会的服务性功能。这意味，从开发和到后面运营，需要不断投入大量硬件服务器来促进的网络方展，这意味我们要投入更多人力和物力发展它。
