Bitcoin Private Keys Directory

Help me code it!

Hi everyone, i am learning about Python and it's quite hard with me. I want to calculate Public key from Private key with ECC. I have the code from Github, transform it to Python 3.0 and it does not work:
# Super simple Elliptic Curve Presentation. No imported libraries, wrappers, nothing. # For educational purposes only. Remember to use Python 2.7.6 or lower. You'll need to make changes for Python 3. # Below are the public specs for Bitcoin's curve - the secp256k1 import binascii Pcurve = 2**256 - 2**32 - 2**9 - 2**8 - 2**7 - 2**6 - 2**4 -1 # The proven prime N=0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364141 # Number of points in the field Acurve = 0; Bcurve = 7 # These two defines the elliptic curve. y^2 = x^3 + Acurve * x + Bcurve Gx = 55066263022277343669578718895168534326250603453777594175500187360389116729240 Gy = 32670510020758816978083085130507043184471273380659243275938904335757337482424 GPoint = (Gx,Gy) # This is our generator point.

LamAdd = ((b[1]-a[1]) * modinv(b[0]-a[0],Pcurve)) % Pcurve x = (LamAdd*LamAdd-a[0]-b[0]) % Pcurve y = (LamAdd*(a[0]-x)-a[1]) % Pcurve return (x,y) def ECdouble(a): # This is called point doubling, also invented for EC.

Q=ECdouble(Q); print(("DUB", Q[0])); print(i) if ScalarBin[i] == "1": Q=ECadd(Q,GenPoint); print(("ADD", Q[0])); print() return (Q) PublicKey = EccMultiply(GPoint,privKey); print(); print("******* Public Key Generation *********"); print() print("the private key:"); print((hex(privKey))); print() print("the uncompressed public key (not address):"); print(PublicKey); print() print("the uncompressed public key (HEX):"); print(("04" + "%064x" % PublicKey[0] + "%064x" % PublicKey[1])); print(); print("the official Public Key - compressed:"); if PublicKey[1] % 2 == 1: # If the Y value for the Public Key is odd. print(("03"+str(hex(PublicKey[0])[2:-1]).zfill(64))) else: # Or else, if the Y value is even. print(("02"+str(hex(PublicKey[0])[2:-1]).zfill(64)))

Upcoming Updates to Bitcoin Consensus

Price and Libra posts are shit boring, so let's focus on a technical topic for a change.
Let me start by presenting a few of the upcoming Bitcoin consensus changes.
(as these are consensus changes and not P2P changes it does not include erlay or dandelion)
Let's hope the community strongly supports these upcoming updates!

Schnorr

The sexy new signing algo.

Advantages

Disadvantages

MuSig

A provably-secure way for a group of n participants to form an aggregate pubkey and signature. Creating their group pubkey does not require their coordination other than getting individual pubkeys from each participant, but creating their signature does require all participants to be online near-simultaneously.

Advantages

Disadvantages

Taproot

Hiding a Bitcoin SCRIPT inside a pubkey, letting you sign with the pubkey without revealing the SCRIPT, or reveal the SCRIPT without signing with the pubkey.

Advantages

Disadvantages

MAST

Encode each possible branch of a Bitcoin contract separately, and only require revelation of the exact branch taken, without revealing any of the other branches. One of the Taproot script versions will be used to denote a MAST construction. If the contract has only one branch then MAST does not add more overhead.

Advantages

Disadvantages

ELI5: how does the blockchain know that a private key belongs to a public key?

still looking for the best answer to help the public to understand this.
If the private key is so deep secret, how does the network knows that the signer of the tx does hold the private key?

One of my addresses start with DELTA. Learn to manipulate your wallet addresses in 11 simple steps.

One of my Dogecoin addresses starts with DELTA.
You might think I'm elder godly lucky, but the thing is that we can create several combinations of addresses names provided that we follow simple steps.
I'll teach you those simple steps RIGHT NOW.
1 - Download the Vanitygen.
2 - Unzip the Vanitygen zip at "C:\". It should look like "C:\vanitygen-0.20-win" afterwards.
3 - Go to C:\vanitygen-0.20-win. Press Ctrl + Shift + Right click. It will appear a new option "Open command window here". Open it.
4 - At the command window, right click on the superior part. It'll show "Properties". Open it. Turn the "QuickEdit Mode" on. Press OK. (why?)
5 - At the command window, write exactly:
 vanitygen.exe -X 30 D(what you want) 
In the "(what you want)" part, put guess what. The more complex the combination you want, the more time it takes to calculate it. However, not every combination works. For DELTA, you will write
 vanitygen.exe -X 30 DELTA 
If what you want is not possible, the terminal will say something like "Invalid character 'l' in prefix 'Delta'". In this case, I wanted "Delta", but the char "l" wasn't allowed to be put there.
6 - Provided that the combination of letters worked, the Vanity will generate the address and the private key. After it is done, the terminal will show something like this:
 Difficulty: 4553521 Pattern: DELTA Address: DELTAR2TayY... Privkey: (Private Key) 
7 - With the left click of the mouse, select the (Private Key) and press ENTER. This will copy the Private Key.
8 - Open your wallet. Help -> Debug window -> Console
9 - type exactly:
 walletpassphrase (Insert your password here) 60 
You need that 60 at the end. Don't ask me why.
Then type:
importprivkey (Past the Private Key here) 
The wallet may freeze after this. If it does, then close it and open it again.
11 - If everything is right, your DELTA address will be there.

Bitcoin is the currency of the Internet: a distributed, worldwide, decentralized digital money. Unlike traditional currencies such as dollars, bitcoins are issued and managed without any central authority whatsoever. While bitcoin tokens on the original network can't be copied or counterfeited, the protocol is open source and can be recreated with different parameters. We call these Airdrops. This is my story: Several years ago I splitted my bitcoin private key to keep it safe in different places. I lost one part and think I lost my mined bitcoin forever. Suddenly (I think you understand why) I decided to start searching for any parts and I found 3 of 6!!!!
