Happy Bitcoin Cash May-2022 upgrade! Follow up on the 2.5 BCH giveaway (or how I outsourced making history)

First, congratulations to everyone on a smooth and successful Bitcoin Cash upgrade, and I'd dare say biggest upgrade Bitcoin has had since genesis!

I wanted to be part of history so I made sure of it by making a competition and had so much fun observing how it went! Vanity can be fun! :D

1st block using new Bitcoin Cash features has been successfully mined and is full of transactions with the OP_RETURN message:

Happy Bitcoin Cash May-2022 upgrade! - bitcoincashautist

and not one of those TXes was created by me! All of them were made by someone else, taking Bitcoin Cash out of my reward pool! :)

The reward pool has been almost entirely depleted in the first block, so congratulations to the winner or winners! There's now 205 transactions with the competition contract: https://bch.loping.net/address/bitcoincash:pzq2vg8ppftlnk7raj452eae33upjgedj5dnc5efg5 and each transaction that spends from that address has my message, because the contract requires it in order to be spent from :D

It's not the 1st TX in the block, however one of the reward spends made 2nd place, and congrats to whomever sent this one and made the first place. Still, the competition TX is the 1st one that uses and demonstrates features from both CHIPs so mission accomplished!

Also, congrats to ViaBTC and Mr. aziz2025 for mining the first upgraded block!

How does my contract work? It simply requires that:

  • 15/16 of the amount being spent goes back to the same contract address
  • an OP_RETURN output with my message is part of the transaction

The 1/16 is there for the taking and fee payment - winner(s) simply had to fill in their address and repeat the process until they depleted the contract address.

Congrats to all, and I hope to make something more cool for May 2023 upgrade!

PS Here's how the contract looks like in Bitauth IDE if anyone wants to study it.
