[ANN] UBIC:The cryptocurrency providing UBI for the masses using the E-Passport

[ubicorn]

Depending on if your passport uses ECDSA or RSA and the key length the non-transferable proof of signature knowledge can vary from 0.2kb to 4kb. I can add a functionality to allow you to copy the base64 encoded transaction and then to broadcast it on the network using a connected node.

You can also take a look at how the code works, although I agree that it would take a lot of time to read it all.
Here is the most important part: https://github.com/UBIC-repo/core/blob/85993a7bfc31803a37f171d4f0657cfab8c3eb32/JSON/Api.cpp#L631

Bellow is the simplified code with explanations:

Code:

std::string Api::readPassport(std::string json) {

[...]

    if(reader->initConnection(bacKeys, sessionKeys)) // open connection with the passport through NFC
    {
        unsigned char fileId[3] = {'\x01', '\x1D', '\0'}; // EF.SOD file identifier

        if(!reader->readFile(fileId, file, &fileSize, sessionKeys)) { // reading out the SOD file (digitally signed file to verify the authenticity of the passport)
            reader->close();
            return "{\"success\": false, \"error\" : \"failed to read SOD file\"}";
        }
        reader->close();

[...]

        ldsParser->getTag((unsigned char*)"\x77")
                ->getContent(sod, &sodSize); // the SOD file is a ASN1 encoded file containing another PKCS7 file. We get this file here
[...]

        PKCS7Parser* pkcs7Parser = new PKCS7Parser((char*)sod, sodSize); // Parsing the PKCS7 file to extract the Document Signing Certificate, the signed hash and the digital signature
[...]

        Address randomWalletAddress = wallet.getRandomAddressFromWallet(); // get a random address from our wallet, this address will receive the UBI

        if(pkcs7Parser->isRSA()) { // if the parsed PKCS7 file contained a RSA certificate
[...]

            NtpRskSignatureVerificationObject *ntpRskSignatureVerificationObject = NtpRsk::signWithNtpRsk(
                    ntpRskSignatureRequestObject
            );

            CDataStream sntpRsk(SER_DISK, 1);
            sntpRsk << *ntpRskSignatureVerificationObject; // serialize the object

            Log(LOG_LEVEL_INFO) << "generated NtpRsk: " << sntpRsk;
            pIScript->setScript((unsigned char *) sntpRsk.data(), (uint16_t) sntpRsk.size());

            pTxIn->setScript(*pIScript); // set the non-transferable proof of signature knowledge as transaction input

        } else {
            // similar to as with RSA but for ECDSA
            [...]
        }

        [...]

        if(txPool.appendTransaction(*registerPassportTx)) { // Broadcast the transaction on the network
            Network &network = Network::Instance();
            network.broadCastTransaction(*registerPassportTx);
            return "{\"success\": true}";
        }

    [...]

}

I released V0.1.6 it fixes crashes due to register passport transactions. Make sure to update your node.

How to install update? I get a message on the phone "no supporting apps for this tag installed"

[ubicorn]

How to install update?

Code:

/etc/init.d/ubic stop
cd /usr/local/src/
sudo rm -rf core
sudo git clone https://github.com/UBIC-repo/core.git
sudo chmod 777 -R core
cd /usr/local/src/core
cmake CMakeLists.txt
sudo make install
/etc/init.d/ubic start

This should do it

To register your passport you need to connect a usb NFC reader to your computer.
I'll write you as soon a mobile app is ready, I already got in touch with some people that are interested in doing it.

Just to let you know that I reserved the domain http://ubic.news
I a m not sure what I ll make with it. Let's see.

What is the purpose of creating a UBIC token, what specific tasks will your tokens solve, what is the value of the UBIC token? What is the maximum number of issued UBIC tokens, when you plan to go to the exchanges, how much does the 1 UBIC token?

[uboid]

I am also running a node with the IP address 51.15.99.155
This might be useful.

You'll find most answers in the whitepaper: https://github.com/UBIC-repo/Whitepaper

But summarize

What is the purpose of creating a UBIC token

UBIC aims to distribute coins following universal basic income principles.
Instead of rewarding coins proportionally to your computing power every citizen of one of the supported countries will be rewarded with tokens just for being a human being and being part of the UBIC network.

What specific tasks will your tokens solve

It aims to solve the distribution problems resulting from POW and POS. It also solve a security issue called sybil attack and has possible KYC and E-Voting applications.

What is the value of the UBIC token?

The value of a token depends on the size of it's network effect.
Because participants that have registered their passports are rewarded with a UBI, the incentive to join UBIC as a user can be higher than with other cryptocurrencies.
This will hopefully result in a great network effect

What is the maximum number of issued UBIC tokens

Unlike Bitcoin UBIC has no cap. The amounts you saw in the first post are static and will be issued every year.
The real number of coins in circulation will however be lower as all transaction fees are burned to limit inflation.

When you plan to go to the exchange

I can not give any ETA

how much does the 1 UBIC token?

I didn't understood this part

Thank you! I just added it here: https://github.com/UBIC-repo/node-list/blob/master/nodes
If some one else wants to add a node he can directly create a pull request there.

Just after I registered my passport my SSD died, luckily it's still readable.
Where can I find my wallet keys to save then?
If you lose your keys is it possible to recover your coins using your passport?

The seed of your private keys location is: ~/ubic/wallet.dat
This is the only file you need to backup, it's 33 bytes in size.
Currently there is no way to recover your private keys or seed from your passport, once the seed is gone your coins are too.

Yes

Has some one else here already tried to register his passport?

[freepellent]

Do not have NFC usb scanner to register passport. Waiting for a mobile app.

From where are you from?

[ubicorn]

If you are using a firewall make sure that port 1334 is open or TCP connections.
This can be ensured by running:

Code:

sudo ufw allow 1334/tcp 

Also your log files might getting huge.You can delete them by running:

Code:

sudo rm -rf /var/ubic/LOGS/*.txt

Wow, I had a look at the WARNING log file and looks like some people are already trying to steal some coins.

Code:
