b00b5Coin [ ٩( ᐛ )و ( o Y o ) ]

Another cryptocurrency built for study (!scientific) purposes. Designed and built with all the love in the world by Gianluca Pericoli

Algorithms

Proof of Work

It's just the HEX representation of SHA256 of the JSON Object (minified) on one block.

The difficulty is calculated in NIPPLES

           .-''-''-.
          /   '-'  .: __
  .._    /  /|||\\  Y`  `\
 |:  `-.J  /__ __.., )   |
 |  .   ( ( ==|<== : )   |
 :   `.(  )\ _L__ /( )   |
  \    \(  )\\__//(  )   |
   \    \  ):`'':(  /    \
    -_   -.-   .'-'` ` . |
     `. :           .  ' :
      )            :    /

     \   /   \     / /     | ' ` `-' '   '   `-' `-' `-'
      `i`     `---' /

How nipples work:

0 Nip: b000b5FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF 
1 Nip: b000b57FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF 
2 Nip: b000b53FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF 
3 Nip: b000b51FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF 
4 Nip: b0000b5FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF 
...
236 Nip: b0000000000000000000000000000000000000000000000000000000000000b5

for least significant bit after b00[0]*5:

1111: f
0111: 7
0011: 3
0001: 1
0000: 0 ---> adds a 0 in b00b5

Transactions

To sign transactions we will use ECDSA

https://it.wikipedia.org/wiki/Elliptic_Curve_Digital_Signature_Algorithm

we will use "ed25519" curve for address generation:

https://en.wikipedia.org/wiki/Curve25519

why?

https://safecurves.cr.yp.to/

and it's also supported by the elliptic library for NodeJS

Address

Generated from the public key:

RIPEMD160( SHA256( publicKey ) )

Block Generation

Generated every 0x101 hex (LOL) seconds, 257seconds minutes, ~ 4 minutes.

Nipples are calculated with an average 0xA55 hex (ASS) blocks, 2545 blocks, if time > 0x101 hex go up. Otherwise it goes down.

Miner Reward & Halving

The b00b5Coin reward starts from 1024 (2^10) Coins per block, the halving of the reward is every 0xb00b5 (721.077) blocks, every ~5 years.

let sum = 0;
for(let i=0; i<=10; i++){
    let reward = Math.pow(2, i);
    console.log("Reward: " + reward + " Total: " + reward* 0xB00B5);
    sum += reward * 0xB00B5;
}
console.log("Total Reward: " + sum);
// 1.476.044.619 of b00b135
