From 10a57fc3d45cbc59d6c8eeb0f7f2b93a71e8f4c9 Mon Sep 17 00:00:00 2001 From: Jeffrey Wilcke Date: Wed, 1 Feb 2017 22:36:51 +0100 Subject: 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) --- params/util.go | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) (limited to 'params/util.go') diff --git a/params/util.go b/params/util.go index bf833d510..d4d43d047 100644 --- a/params/util.go +++ b/params/util.go @@ -17,6 +17,7 @@ package params import ( + "math" "math/big" "github.com/ethereum/go-ethereum/common" @@ -38,6 +39,9 @@ var ( TestNetSpuriousDragon = big.NewInt(10) MainNetSpuriousDragon = big.NewInt(2675000) - TestNetChainID = big.NewInt(3) // Testnet default chain ID - MainNetChainID = big.NewInt(1) // Mainnet default chain ID + TestNetMetropolisBlock = big.NewInt(math.MaxInt64) + MainNetMetropolisBlock = big.NewInt(math.MaxInt64) + + TestNetChainID = big.NewInt(3) // Test net default chain ID + MainNetChainID = big.NewInt(1) // main net default chain ID ) -- cgit v1.2.3
