* params: Updated finalized gascosts for ECMUL/MODEXP (#15135)Martin Holst Swende2017-09-141-2/+2
| | | | | | | | | | | | * params: Updated finalized gascosts for ECMUL/MODEXP * core,tests: Updates pending new tests * tests: Updated with new tests * core: revert state transition bugfix * tests: Add expected failures due to #15119
* core/vm: polish precompile contract code, add tests and benchesPéter Szilágyi2017-08-141-8/+16
| | | | | * Update modexp gas calculation to new version * Fix modexp modulo 0 special case to return zero
* params: core, core/vm, miner: 64bit gas instructionsJeffrey Wilcke2017-02-141-49/+51
| | | | | | | | | | | | | | | | | Reworked the EVM gas instructions to use 64bit integers rather than arbitrary size big ints. All gas operations, be it additions, multiplications or divisions, are checked and guarded against 64 bit integer overflows. In additon, most of the protocol paramaters in the params package have been converted to uint64 and are now constants rather than variables. * common/math: added overflow check ops * core: vmenv, env renamed to evm * eth, internal/ethapi, les: unmetered eth_call and cancel methods * core/vm: implemented big.Int pool for evm instructions * core/vm: unexported intPool methods & verification methods * core/vm: added memoryGasCost overflow check and test

* core, core/vm: added gas price variance tableJeffrey Wilcke2016-10-151-0/+1
| | | | | | | | | | | | | This implements 1b & 1c of EIP150 by adding a new GasTable which must be returned from the RuleSet config method. This table is used to determine the gas prices for the current epoch. Please note that when the CreateBySuicide gas price is set it is assumed that we're in the new epoch phase. In addition this PR will serve as temporary basis while refactorisation in being done in the EVM64 PR, which will substentially overhaul the gas price code.
* core: added basic chain configurationJeffrey Wilcke2016-04-011-2/+3
| | | | | | | | | Added chain configuration options and write out during genesis database insertion. If no "config" was found, nothing is written to the database. Configurations are written on a per genesis base. This means that any chain (which is identified by it's genesis hash) can have their own chain settings.
* params: settle the Pi vs Tau disputeJeffrey Wilcke2016-02-261-1/+1

* Read most protocol params from common/params.jsonGustav Simonsson2015-04-021-0/+54
* Add params package with exported variables generated from github.com/ethereum/common/blob/master/params.json * Use params package variables in applicable places * Add check for minimum gas limit in validation of block's gas limit * Remove common/params.json from go-ethereum to avoid outdated version of it
