+## TODO
+
+* Make minigeth use the 0xD0000000 input oracle / add input oracle to risc/run.py. See [contracts/Challenge.sol](https://github.com/geohot/cannon/blob/master/contracts/Challenge.sol)
+* Add blocks / tx trie to the preimage oracle [see issue](https://github.com/geohot/cannon/issues/2)
+* Finish and test the MIPS state transition function in contracts/MIPS.sol
+* Get minigeth running in Solidity MIPS emulator with reasonable performance (Go code using EVM with native memory)
+* Add merkleization for MIPS ReadMemory and WriteMemory
+
 ## Usage
