else if one year has elapsed since contract started transfer security deposit to tenant end contract This ignores the reason for a deposit in the first place. What if the carpets were burned in that year? Some of the deposit needs to be kept by the landlord. How does etherium know the carpet was burned? If the landlord says so, then the landlord may be lying. For simpler operation - if rent not paid - then end contract - that sounds like it adds no benefit. No need for a program to tell you the contract has ended. This is very useful to prove authenticity of a contract and for very simple contracts as well such as a bet. If there can be any sort of dispute about the contract though I don't see how it can be useful again save for authenticity.
