Cryptocurrency mining is wasting of computing power now. Also, 84% (17,5 of 21 million) of BTC total supply are mined already and many coins are lost. People can use mining computing power for useful calculations in scientific, commercial and any other useful purposes. This project is an idea of creating a new cryptocurrency, which mining allows to use calculating power for searching lost wallets private keys and other useful calculations, provided by capitalization of lost coins and profit of calculations. We hope anyone will get an ability to get a whole network for useful calculations or any useful purposes, so a new coin will be also provided by it's work and profit in future.
Private key is a random 64 bit hex number. Most cryptocurrencies uses same elliptic curve secp256k1 (y2=x3+7) to get the public key from private.
Public key = ECDSA (private key)
By applying the ECDSA to the private key, we get a 64-byte integer, which is two 32-byte integers that represent X and Y of the point on the elliptic curve, concatenated together.
Creating a public key, secp256k1 standart
Public key = private key * generator point
The elliptic curve domain parameters over Fp associated with a Koblitz curve secp256k1 are specified by the sextuple T = (p,a,b,G,n,h) where the finite field Fp is defined by:
p is prime
p = FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFE FFFFFC2F
= 2**256 - 2**32 - 2**9 - 2**8 - 2**7 - 2**6 - 2**4 - 1
The curve E: y2 = x3+ax+b over Fp is defined by:
a = 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000
b = 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000007
The base point G in compressed form is:
G is generator point
G = 02 79BE667E F9DCBBAC 55A06295 CE870B07 029BFCDB 2DCE28D9 59F2815B 16F81798
and in uncompressed form is:
G = 04 79BE667E F9DCBBAC 55A06295 CE870B07 029BFCDB 2DCE28D9 59F2815B 16F81798 483ADA77 26A3C465 5DA4FBFC 0E1108A8 FD17B448 A6855419 9C47D08F FB10D4B8
Finally the order n of G and the cofactor are:
n = FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFE BAAEDCE6 AF48A03B BFD25E8C D0364141
n is number of the points in the field
h = 01
h is cofactor
Once we’ve gotten the public key, we can calculate the address.
Address = Base58 encoding (Network bytes "00" & RIPEMD-160(SHA-256(Public key)) & first 4 bytes of SHA-256(SHA-256(RIPEMD-160(SHA-256(Public key))))
The difference is network bytes.
Address = "0x" + last 20 bytes of Keccak-256(Public key)
To make an address from the public key, we need to apply Keccak-256 to the key and then take the last 20 bytes of the result.
How to delete your address from SecretScan's searching datababe?
Just join our telegram channel or send us your wallet address by e-mail. You will get an info how to confirm that it is your address.
Why is it harder to generate addresses starting with 1s?
An address has 1 + 20 + 4 bytes, which has a total of 200 bits. Each of the Base58 characters contain log_2 58 bits of information, which is approximately 5.858. If one created an address that has the public key hash 0000...00, the result would be a 5-6 character address, due to the checksum. To prevent this, Satoshi decided to add "1"s for each 0x00 byte in front of the address. Those "1"s each contain 8 bits of information instead of 5.85... As they carry more information, it's harder to find an address starting with those 1s
How to use BTC private key?
Download the Electrum Bitcoin wallet program. Run the program, create a wallet using the private key. Set a password to enter. For Segwit P2SH and Bech32 addresses, open a console, enter importprivkey ('p2wpkh-p2sh: Private Key') and / or importprivkey ('p2wpkh: Private Key').
