The SPAM system has two components:

• An onchain mechanism to track user transactions, calculate rewards per user, and let users mint $SPAM in proportion to the number of txs they sent.
• A web miner for users to easily send lots of transactions automatically, as well as mint and claim $SPAM coins.

Let's dig in at different levels of analysis:

ELI5

• One billion $SPAM coins are minted every day.
• Users earn $SPAM by sending Sui transactions.
• The more txs you send, the more $SPAM you receive.
• There is no proof of work, only proof of spam.

MECHANISM

A Sui "epoch" is roughly equivalent to 1 day.

Users send txs to increase their tx counters during epoch N, register their tx counters during epoch N+1, and mint $SPAM anytime from epoch N+2 based on the spamming they did in epoch N:

• Epoch 0: user spams UserCounter.0 (UC.0)
• Epoch 1: user spams UC.1, registers UC.0
• Epoch 2: user spams UC.2, registers UC.1, claims UC.0
• Epoch 3: user spams UC.3, registers UC.2, claims UC.1
• And so on

IMPLEMENTATION

• Single-writer UserCounter objects are used to track the number of txs sent by each user within one epoch.
• When that epoch ends, the user registers their UserCounter in a shared object, so that the total number of txs in the previous epoch can be calculated.
• After that next epoch (registration period) ends, users can mint $SPAM coins in proportion to the number of txs they sent.
