 Blockchain

What is blockchain technology?

It's a digital database

Involved in cryptocurrency.

"Miners" seek to win the "hash" race.

Ideally the winner is

"Proven" by the blockchain in use,

And profits from the trading biz.

Where there's greed there can be abuse.

So I did figure out a scheme

To try to block the blockchain fact.

It would have been a swindler's dream.

Alas, I got caught in the act.

Blockchain turned into hard time, dang,

In a cell block, on a chain gang.
