Handshaking can lead to sudden end of game

[vrde]

Scope

• Right now anyone can handshake as much as they want with anyone else.
• This behavior can produce a huge amount of CO₂ and lead to the sudden end of the game just because two players decide to ruin the game for anyone else.
• Nothing stops a player to write a bot to handshake for them forever.
• Consider that the game will be played by experts so client side solutions can be easily bypassed.

Deliverables

• A way to "rate limit" handshaking with the same player.

option A: still implement it on the client side 😁 writing a script to handshake and explode the planet is not alligned with the interests of any-one, as swag becomes infinitely expensive.

option B: Store in the passport whom the user handshaked with using a merkle tree and proof structures.
