Sol-Anon is an on-chain inbox program built on Solana. It leverages the spam commonly occuring on the network by providing a whitelist mechanism for trusted senders. Non-whitelisted (spammers) subsidise the rent costs for whitelisted users by creating slots for them. Whitelisted users can then use these slots to store messages.
