The Commodore 64 is immortal and we all know how widely loved it is by the community around the world. And in a period like this, where Bitcoin mining reigns supreme and the necessary hardware for market crises is lacking, why not take advantage of what has been well preserved in a closet? So someone has well thought of mining Bitcoin on a Commodore 64 !
A famous youtuber, 8-Bit Show and Tell, was able to "modify" his console successfully to actually be able to access the Bitcoin blockchain network and thus undermine them.
The performance obtained is exactly what you expect
This is a commendable result, but it still leaves the time it finds to those who are really interested in the world of mining. We are talking about performance of about 0.3 Hash / s , and the software used was written in C. According to the author, a certain increase in performance could be obtained by writing it directly in machine language , with results up to 10 times higher.
It would also be possible to perform a hardware upgrade using the SuperCPU, thus reaching speeds up to 20 times higher.
Ok I want to do it: how long will it be before I can get my Bitcoin?
If you are now interested in dusting off your Commodore 64 to undermine it, know that to successfully mine one you will need about $ 1 quadrillion and roughly 50 trillion years of life . At 10 H / s it would mean about 0.0t0000000000002 Bitcoin per year.
If, however, you are curious about the "retro-mining" topic, know that there are also those who have succeeded in this enterprise using one of the computers of the Apollo missions !
A little history on the Commodore 64
The Commodore 64 , abbreviated C64, was launched by CBM in 1982 and was equipped with a MOS technology processor with an operating frequency of 1023 MHz or even 985 MHz, depending on the version. The processor was thus accompanied by 64KB of RAM (which is what made it known at the time) and 20KB of ROM .
It makes you smile (and think too) looking at the specs listed above. Specifications that were at the top at the time, but today are only a distant memory. However, this points out, with great pleasure, what technological advances have been in recent decades .
Basic operation of Bitcoin: blockchain and mining
The blockchain that is so much talked about is a sort of public and shared ledger , on which the entire Bitcoin network is based. All transactions that are confirmed are included in this network, so Bitcoin wallets can calculate their available balance. Each new transition is then verified at the network level, making sure that the spenders have sufficient availability.
All transactions traveling in the blockchain are encrypted via a public-private key mechanism. The private key is then used to digitally sign transactions, providing mathematical proof of the origin of the transaction from the wallet owner. The digital signature also prevents the transaction from being tampered with.
The other users of the blockchain network confirm the transitions, through a process called mining. In fact, to be confirmed, the pending transactions are packaged in a block that complies with very strict cryptographic rules, which will then be verified by the network.
