* core: consider reset round when getting config stateWei-Ning Huang2019-09-173-9/+35
| | | | | | | | | | | | | | | | | | Previous config snapshot is determined as follows, for round n: Return the snapshot state of round (n - ConfigRoundShift) However this may cause the system to stuck at a particular round if the DKG for the next round continues to fail (maybe due to node failure). To fix this, instead of using the simple logic above, we consider the reset rounds as a normal round, and use the snapshot of the reset rounds as config. Thus we could gradually push out the broken nodes from nodeset. The snapshot is now determined as follows, for round n: If resetCount < ConfigRoundShift Return the snapshot state of round (n - ConfigRoundShift) Else Reutrn the stateshot state of (n + resetCount - ConfigRoundShift)
* core: add GovUtil to unify governance state related accessWei-Ning Huang2019-09-178-179/+227
| | | | | Add GovUtil so we could use the same logic in everywhere that requires access to governance state, such as configuration and CRS.

* consensus: dexcon: disqualify dead node (#280)Wei-Ning Huang2019-06-134-39/+230
| | | | | | | | | | Since a qualified node might fail stopped, we need to remove them from qualified nodes to maintain network integrity. We do this by inspect the previous round to see if there are dead nodes. A dead node is a notary set node that does not propose any block in the previous round. We disqualify them by fining them so their staked value is 1 wei below minStake. This make them unqualified for being notary set in the follow on rounds.

* core: vm: remove delegation mechanism (#245)Wei-Ning Huang2019-06-126-997/+263
| | | | | | | | | | | | | The current delegation mechanism are prone to unstaking attack. i.e. a malicious attacker could unstake a small amount from a lot of node it staked before and make them unqualified, which leads to potential failure of the network. Since DEXON does not use consensus like DPoS, node is required to have at least MinStake in order to become a node. Voting mechanism is not required in our system since qualified node does not depends on the number of votes. Instead of managing the delegation mechanism in governance contract, we should let the owner manage the delegation and reward distribution mechanism on their own.

| | | | | | There are two keys in the system: one is the owner's key which is used for stake / unstake. The other is the node key which is used for DKG related operations. We need to allow them to be different so fund renmains safe even if the the node key is lost.

* core: vm: modify randomness calculation algorithm (#173)Wei-Ning Huang2019-06-122-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | The original algorithm used for calculating algorithm is vulnerable to cross context re-entry attack. Example as follows: contract B { event Value(uint256 value); uint256 public value; function call() public { value = rand; emit Value(value); } } contract A { function randTwice(address bAddr) public { B b = B(bAddr); b.call.gas(100000)(); b.call.gas(100000)(); } } The two `b.call` will result in the same randomness value. This commit fix the issue by recording a called index used to store how many times opRand is called, and use it as argument to the Keccak call.

* core, dex: use block hash as witness data (#160)Sonic2019-06-125-50/+17
| | | | | | | | | | Using only state root and receipt root as witness data can not protect other fields in block header, ex: bloom, difficulty, gas limit, gas used... So that everyone can manipulate these fields to create as many valid blocks at the same height as he want. Although this will not effect the state, one can spam us when syncing. Using block hash as witness data can solve this.

* core, dex: polish sync (#75)Sonic2019-06-121-0/+3
| | | | | | | | | | | | | | | - Broadcasting blocks at chain head event is not correct when the full node is not running in block proposer mode. Introduce NewFinalizedBlockEvent, this event is post by the full node which runs in block proposer mode when a block is witnessed and resulting in some blocks are considered finalized. - Non block proposer node will still broadcast blocks at the following moment (same as ethereum): 1. a sync with a peer is terminated successfully 2. a block passes the fetcher's header check during inserting blocks 3. a block is successfully inserted by fetcher - Don't trigger a sync when we are not behind other peers more than acceptable distance. Fetcher is able to cover this.

| | | | | Also rename InsertChain2, insertChain2, InsertHeaderChain2, ValidateHeaderChain2
* dex: implement downloader for dexSonic2019-06-121-0/+5
| | | | | | | | | | | We need governance state to verify block's signature (randomness), but in ethereum fast sync mode, eth downloader only downloads the whole state of pivot block, so we don't have governance state to verify the downloaded block that is before pivot block if we don't processing transaction. To avoid running transactions, dex downloader also downloads the governance state (merkle proof and storage) at snapshot height of each round, so that we can verify blocks in fast sync mode.

| | | | | From the go trace result, the bottleneck hides in the lock of StoreTxCache. To improve this, we update the cache in a batched fassion.
