Cool new applications in crypto using ZK

Approve transactions just by sending an email (ZkEmail)

What is it about? For many users, downloading a wallet and learning how to send a transaction is too much friction (think of your grandmother). But sending money just by sending an email from person A to person B is perfectly possible. Or making a multisig wallet (wallet controlled by several people) is extremely easy to manage with emails.

Approve transactions with your ID card (MynaWallet)

What is it about? Not only for the reasons above, but it also allows me to use it as a PRIVATE anti-bot online identification method (aka anti-sybil). So I can vote, poll, ask for loans, etc. privately and anonymously but still claiming to be Japanese.

Instead of using exchanges... Use Venmo, Revolut... and eventually SINPE? (ZKP2P)

What is it about?

For onramping (buying crypto), many use exchanges and private companies... Aside from the terrible privacy and fees, exchanges are a "choke point" for crypto. ZKP2P allows you to buy and sell crypto directly using your "web2 payers" in the world without asking their permission. You send a payment via Revolut to someone and you "unlock" a crypto that becomes yours. Several of these teams went to the Signature Singularity Residency in Japan and here is the recording of the demos (1 hour) https://www.youtube.com/watch?v=rT7zLiOYX8s
