Vaxx passports, carbon credit and digital id are different from cryptocurrency.

See cryptocurrency or more specifically the blockchains have a feature called smart contracts, which is basically decentralized applications running on blockchain with the blockchain as it's distributed database.

This is how they intend to operate the "carbon credit/vaxx passport id" system, it'll all be combined, because the technology is cheap, secure and reliable. If blockchains didn't exist they could have easily built it all on their own already existing server farms too.

But wait a minute, why have carbon credit if there's dollars and fiat currency you might ask. Well simply put fiat is and was always doomed to fail, it has built in permanent inflation and will drop to zero value within just years, any profit from the inflation goes straight down the globalists own pockets which they then use to build the infrastructure the new world order needs to enslave humanity.

You won't have to pay electric bills, you can't buy electricity, you get a certain amount of carbon credit which you can then spend on electricity. This is all done on demand to encourage you to save and live "environmentally friendly". Once you're out of carbon credit no more power for you. Every single device will be "smart" and interact with this network.

I don't know exactly what role cryptocurrency will have in all this, but you should know that cryptocurrency is how you pay your bills on the blockchain, so it will be the real actual money of the future, but the elite will claim monopoly over it by tracking down holders and perhaps offer you to join them, or die. This to eliminate any threat. Humans are also corrupt by nature so crypto will be the black market money as well.
