There are still a few things to be resolved before I get started on this as I’m just going to be using images drawn by the user. However, it is a fairly good course and I will update you with my progress when it’s available.

It’s no secret that many of us in the cryptocurrency world use BitPay.com. This site, through some clever pricing, is one of the primary places that we are able to pay for transactions. They do offer a number of other payment methods, namely PayPal, but those are limited in terms of transaction capabilities. As a digital currency holder, and someone who also writes about it, I found that quite a few people would pay for transactions on the site that they couldn’t process due to their payment credentials. I thought this was odd – at least for a website that wants to get customers for bitcoins or BitcoinCash.
Now there are a number of solutions out there for this situation. Let’s take an example with BitPay. I’ll write a small script to collect the first few bytes of the payment information:
[bitcoin address] BTC = 1aDj4qzCzY7wMbQp6rWwvDZv4jyEqX2Kk2n
You will notice that a ‘$’ is being appended to BitPay.com’s address. This indicates that they have successfully verified the Bitcoin address in the bitcoin blockchain. Since Bitcoin is a pseudonymous transaction, we’ll have to verify this by seeing if they provide one of their own.
To do this, all we need is just the first four bytes of BitPay’s payment information (if they provide one, we’re good):
(e) [0x080000] (f) [0x9ffffff] (g) [0xffffffff8] (h) [0xffffffffc0] (i) [0x00000000]
This will do it for us – we’ll have to verify that we’re receiving bitcoins on the BTC address using our own private key. Let’s add this to the script:
b = raw_input(“Enter your bitcoin address: “) i = raw_input(“Enter your private key for verification: “) print i.split(‘:’)[0x28]
We’ll do some sanity checks here – we’ll verify that the address we’re currently receiving bitcoins from
