Project of useful Calculations
We are making a cryptocurrency of usefull computing power


Cryptocurrency mining is worthless wasting of computing power and electricity now. Also, 84% (17,5 of 21 million) of BTC total supply are mined already and many coins are lost, because it was unfair distribution at the beginning and the owners didn't appreciate it. So people are spending more and more power and get less and less reward instead of mining for lost wallet private keys to get long lost coins, or using 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, provided by capitalization of lost coins. Later, anyone will get an ability to rent a whole network for useful calculations or any useful purposes, so a new coin will be also provided by work and profit.
1
Generating
The Scanner > is generating private keys, public keys and calculating cryptocurrencies addresses of each key. Try our Generator > to understand how it works.
2
Checking
Then we are checking computed addresses against our database. It consist 17 cryptocurrencies and millions addresses. Most of them you will find there: Addresses >.
3
Waiting
If an address is in database then we know a private key and we can use it. The owner of coins is just whoever has its private key, however, we will make transaction to another address and will wait for a month if this address lost, dormant or has an owner to return coins to the owner.
4
Sending
If no owner of the coins in a month and more then they are lost or dormant and participants can use it in proportion to the number of keys generated and verified.
Since 01.01.2020, at the beginning of each month, participants will be charged 1,000,000 SSC tokens in proportion to the number of verified private keys for the previous month, which is equivalent to 23 SSC per minute (for comparison, 1 BTC, 12 ETH, 60 GRIN per minute are generated, 5 BTC/min, 18 ETH/min before). The first charge will be in the amount of 20 000 000 SSC in proportion to the number of keys of the participants for the entire previous period. Initially, the records will be kept on SecretScan, later on the contract will be transferred to ERC-20 on the basis of the broadcast. Later, the launch of the decentralized blockchain SSC is planned as the number of developers and investments in the project increases. Participants and investors will be able to buy and sell their SSC by exchanging them on the market. In case of successful finding of abandoned addresses, the found will go to the SSC redemption from the participants and investors, thereby removing them from circulation and increasing the market value.


How to get address from private key. Step by step.

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.

Bitcoin
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))))

Altcoins
The difference is network bytes.

Ethereum
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').
