Matthew Di Ferrante	80c6dfc19f	crypto/bn256: fix generator on G1 (#15591) ... Generator in the current lib uses -2 as the y point when doing ScalarBaseMult, this makes it so that points/signatures generated from libs like py_ecc don't match/validate as pretty much all other libs (including libsnark) have (1, 2) as the standard generator. This does not affect consensus as the generator is never used in the VM, points are always explicitly defined and there is not ScalarBaseMult op - it only makes it so that doing "import github.com/ethereum/go-ethereum/crypto/bn256" doesn't generate bad points in userland tools.	7 years ago

Jeffrey Wilcke	10a57fc3d4	consensus, core/*, params: metropolis preparation refactor ... This commit is a preparation for the upcoming metropolis hardfork. It prepares the state, core and vm packages such that integration with metropolis becomes less of a hassle. * Difficulty calculation requires header instead of individual parameters * statedb.StartRecord renamed to statedb.Prepare and added Finalise method required by metropolis, which removes unwanted accounts from the state (i.e. selfdestruct) * State keeps record of destructed objects (in addition to dirty objects) * core/vm pre-compiles may now return errors * core/vm pre-compiles gas check now take the full byte slice as argument instead of just the size * core/vm now keeps several hard-fork instruction tables instead of a single instruction table and removes the need for hard-fork checks in the instructions * core/vm contains a empty restruction function which is added in preparation of metropolis write-only mode operations * Adds the bn256 curve * Adds and sets the metropolis chain config block parameters (2^64-1)	8 years ago
