When Sara and Daniel's teacher implements electronic Bin Coin rewards for collecting trash and recycling, the kids start using this digital currency to buy and sell. Their developing system for keeping track of accounts brings in concepts from the world of cryptocurrency such as mining a block (recording trades that have been validated), a cryptographic nonce (a number used only once), a mempool (the memory pool for storing trades not yet validated) and a double spend attack .

And during a visit from the State Board of Education, who pulled the fire alarm before the block could be mined?
