Programs can still be directly implanted into the #Bitcoin blockchain using the last 8 digits in it's decimal system (X.00000000) for as cheap as 0.1 $BTC minus transaction fees.

Approx. $350 USD + a lot of TX fees.

Each transaction will store 1 byte of Binary code.

There are two possible states in a "bit", usually expressed as 0 and 1

A series of eight bits strung together makes a byte (X.00000000 : TX amount)

With 8 bits (8 binary digits) there exist 2^8=256 possible combinations. I assume this is the basis for SHA-256 encryption 🎓

This can only be done efficiently while $BTC is still affordable.

To store each byte of program will cost 1 transaction (TX)

1kb = 1,000 TX's
1mb = 1,000,000 TX's
1gb = 1,000,000,000 TX's
1tb = 1 trillion transactions
