From 445feaeef58bd89a113743dccf6fd5df55cde6fa Mon Sep 17 00:00:00 2001 From: Jeffrey Wilcke Date: Thu, 20 Oct 2016 13:36:29 +0200 Subject: core, core/state, trie: EIP158, reprice & skip empty account write This commit implements EIP158 part 1, 2, 3 & 4 1. If an account is empty it's no longer written to the trie. An empty account is defined as (balance=0, nonce=0, storage=0, code=0). 2. Delete an empty account if it's touched 3. An empty account is redefined as either non-existent or empty. 4. Zero value calls and zero value suicides no longer consume the 25k reation costs. params: moved core/config to params Signed-off-by: Jeffrey Wilcke --- light/lightchain.go | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'light/lightchain.go') diff --git a/light/lightchain.go b/light/lightchain.go index 461030369..4e895db61 100644 --- a/light/lightchain.go +++ b/light/lightchain.go @@ -29,6 +29,7 @@ import ( "github.com/ethereum/go-ethereum/event" "github.com/ethereum/go-ethereum/logger" "github.com/ethereum/go-ethereum/logger/glog" + "github.com/ethereum/go-ethereum/params" "github.com/ethereum/go-ethereum/pow" "github.com/ethereum/go-ethereum/rlp" "github.com/hashicorp/golang-lru" @@ -71,7 +72,7 @@ type LightChain struct { // NewLightChain returns a fully initialised light chain using information // available in the database.
