A very simple random generator. A miner can influence the number by not publishing a block with an unwanted outcome, and forfeiting the 5 block reward.
contract random {
/* Generates a random number from 0 to 100 based on the last block hash */
function randomGen(uint seed) constant returns (uint randomNumber) {
return(uint(sha3(block.blockhash(block.number-1), seed ))%100);
}
/* generates a number from 0 to 2^n based on the last n blocks */
function multiBlockRandomGen(uint seed, uint size) constant returns (uint randomNumber) {
uint n = 0;
for (uint i = 0; i < size; i++){
