blockchainlab <experiment>Bitcoins are transferred between agents and transactions are validated by miners competing in constructing blockchains.
A malicious agent attempts to create a double-spending transaction by submitting multiple payment attemps summing up to a larger amount of coins than he owns. Will the system allow them to spend more than they own?
A malicious miner attempts to create an invalid block that includes a transaction moving bitcoins to their wallet from someone else's without their consensus.
An attacker gains control of more than 50% of the mining power in the network. Will them be able to validate new malicious transactions and get the invalid blocks to survive in the blockchain?
A malicious agent attempts to flood the network with bogus transactions to disrupt the validation process. Will this slow down the network?
A selfish miner attempts to manipulate the network by withholding valid blocks they have found in order to gain an advantage over other miners. They may then release multiple blocks at once in order to invalidate the work of other miners and gain a larger share of the rewards.
