The Bank Of Deposit contract keeps users' ethers in contract's internal storage. This approach allows performing one-to-many payment scheme that is linearly cheaper than a series of individual Ethereum transactions.
The Lottery contract implements probabilistic one-to-many payments described in A Probabilistic Nanopayment Scheme for Golem. The contract allows organizing a lottery for multiple participants. Only one of the participants becomes a winner and gets the right to collect the lottery's reward.
The repository contains Python unit tests for the contracts. The pyethereum is used to implement the tests.
