>+1 | * core: consider reset round when getting config stateWei-Ning Huang2019-09-172-8/+34 | | | | | | | | | | | | | | | | | | 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 Huang2019-09-174-63/+137 | | | | | Add GovUtil so we could use the same logic in everywhere that requires access to governance state, such as configuration and CRS. * import: switch consensus core to ↵Wei-Ning Huang2019-09-172-15/+15 | | | | gitlab.com/tangerine-network/tangerine-consensus * core: vm update oracle contract addressesWei-Ning Huang2019-09-171-2/+5 | * core: vm: update governance test suite nameWei-Ning Huang2019-09-171-20/+20 | * core: vm: remove opRand and use oracle contract to get random numberJhih-Ming Huang2019-09-177-34/+85 | * core: set block timestamp to second instead of millisecondWei-Ning Huang2019-09-171-1/+1 | * core: vm: add updateNodeInfo governance methodWei-Ning Huang2019-09-173-86/+201 | * Rebrand as tangerine-network/go-tangerineWei-Ning Huang2019-09-1729-102/+102 | * core: vm: prevent replace duplicate nodeKeyWei-Ning Huang2019-09-172-3/+24 | * core: vm: fix payFine functionWei-Ning Huang2019-09-172-1/+11 | * core: vm: implement transferNodeOwnershipByFoundation (#399)Wei-Ning Huang2019-06-153-0/+93 | * core: vm: add sanity check for updateConfiguration (#383)Wei-Ning Huang2019-06-151-0/+12 | * core: vm: fix node offset during transfer (#377)Wei-Ning Huang2019-06-152-13/+9 | * core: vm: add withdrawable (#373)Jimmy Hu2019-06-153-15/+66 | * core: vm: refine panic flow (#372)Wei-Ning Huang2019-06-151-15/+7 | | | | Move panic call to immediate location of the error to prevent accidententaly panic on other conditions. * core: vm: clearDKG in resetDKG (#368)Jimmy Hu2019-06-151-0/+8 | * core: vm: fix emitReported (#367)Wei-Ning Huang2019-06-151-6/+15 | * core: vm: prevent setting owner to blackhole (#366)Jimmy Hu2019-06-152-1/+19 | | | | | | * core: vm: prevent setting owner to blackhole * core: vm: same for transferNodeOwner * core: implement DKG success (#362)Jimmy Hu2019-06-153-32/+206 | | | | | | | | * vendor: sync to latest core * core: implmenet dkg success * cmd: govtool: add DKGSuccess * core: vm: improve MPK reverse lookup performanceWei-Ning Huang2019-06-153-82/+92 | | | | | By storing array offset in the original DKGMasterPublicKeyProposed map, we can locate MPK by proposer ID easily. * core: vm: cache GPK to prevent DoS (#335)Wei-Ning Huang2019-06-151-1/+18 | | | | Cache GPK so one can not slow the chain down with the ProposeCRS method call. * core: add cache for DKG MPK and complaint (#334)Wei-Ning Huang2019-06-151-20/+21 | | | | | Since deserializing DKG related items are extremely slow (takes about 3 seconds for 100 items), we cache it in the governance interface. * core: vm: fineFailStopDKG if MPK not registered (#329)Jimmy Hu2019-06-152-12/+29 | | | | | * core: vm: fineFailStopDKG if MPK not registered * prevent on-chain randomness * core: vm: fix fineFailStopDKG (#328)Jimmy Hu2019-06-151-1/+1 | * core: vm: implement node public key replacement (#324)Wei-Ning Huang2019-06-153-1/+102 | * core: vm: clear DKG the right way (#319)Jimmy Hu2019-06-151-1/+1 | * core/vm: resetDKG if ttoo less qualified (#318)Jimmy Hu2019-06-151-1/+9 | * core: vm: make fail stop fine value configurable (#312)Wei-Ning Huang2019-06-153-55/+92 | | | | A node is now quailified only if it has no pending fine and staked >= minstake. * dex: rebuild connection if dkg reset, core/vm: fix gov (#308)Jimmy Hu2019-06-151-0/+12 | | | | | * dex: rebuild connection if dkg reset * core: vm: fix governance contract * core: vm: update set size on node info change (#307)Wei-Ning Huang2019-06-151-8/+4 | | | | | | * core: vm: update set size on node info change * fix typo * core: merge notarySet and DKGSet (#265)Jimmy Hu2019-06-153-78/+25 | | | | | | | | * vendor: sync to latest core * core: merge notarySet and dkgSet * dex: optimize network traffic for finalized block * core: vm: fix DKG reset (#296)Wei-Ning Huang2019-06-132-23/+26 | * core/vm: remove round from addDKG functions (#279)Jimmy Hu2019-06-132-73/+45 | | | | | | | | * vendor: sync to latest core * core/vm: remove addDKG functions * core: fix conflict * core: vm: deny duplicate public key from registering (#289)Wei-Ning Huang2019-06-132-1/+20 | * core: vm: pay fine to governance owner and trigger set size recalculation (#288)Wei-Ning Huang2019-06-131-1/+5 | * consensus: dexcon: disqualify dead node (#280)Wei-Ning Huang2019-06-133-30/+128 | | | | | | | | | | 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: emit event when transfering owner (#277)Wei-Ning Huang2019-06-133-0/+48 | * core: vm: automatically calculate notary set size (#276)Wei-Ning Huang2019-06-133-14/+95 | * core: vm: add extra checks to prevent DKG spamming (#272)Wei-Ning Huang2019-06-123-58/+173 | | | | Add two maps to check the uniqueness of DKGMasterPublicKey and DKGComplaints to prevent malicious actors from spamming it. * core: vm: fix naming consistencyWei-Ning Huang2019-06-122-11/+11 | * core: check reset of dkg types when adding (#268)Jimmy Hu2019-06-121-0/+16 | | | | | | * vendor: sync to latest core * core: check dkg reset * core: vm: reorder minGasPriceLocWei-Ning Huang2019-06-121-1/+1 | * dex: implement recovery mechanism (#258)Wei-Ning Huang2019-06-122-5/+5 | | | | | | | | | * dex: implement recovery mechanism The DEXON recovery protocol allows us to use the Ethereum blockchain as a fallback consensus chain to coordinate recovery. * fix * core: vm: group min gas price with related state variables (#257)Wei-Ning Huang2019-06-123-16/+16 | * core: vm: implement transfer node ownership (#255)Wei-Ning Huang2019-06-123-9/+83 | * core: vm: create new oracle contract instance in each call (#251)Wei-Ning Huang2019-06-123-6/+16 | | | | | Since the VM might be called from different source (downloader, RPC, etc.).

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. * core: vm: expose CRSRound and DKGRound and fix consistency (#236)Wei-Ning Huang2019-06-123-60/+118 | * core: fix dkgJimmy Hu2019-06-121-12/+47 | * dex: fill in correct coinbase address (#223)Wei-Ning Huang2019-06-121-0/+9 | | | Also remove app_test.go because of the refactor bojie@ is working on. * core: vm: validate addDKGMasterPublicKey caller properly (#220)Wei-Ning Huang2019-06-123-60/+59 | | | | | | There are two keys in the system: one is the owner's key which is used for stake / unstake.

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.

Obviously this change is dictated by EVMC design. The EVMC tries to keep the responsibility for EVM features totally inside the VMs, if feasible. This makes VM "stateless" because VM does not need to pass any information between executions, all information is included in parameters of the execute function. * core/vm, tests: update tests, enable constantinople statetests, fix SAR ↵Martin Holst Swende2018-09-041-1/+1 | | | | | | | | | | | | | | | opcode (#17538) This commit does a few things at once: - Updates the tests to contain the latest data from ethereum/tests repo. - Enables Constantinople state tests. This is needed to be able to fuzz-test the evm with constantinople rules. - Fixes the error in opSAR that we've known about for some time. I was kind of saving it to see if we hit upon it with the random test generator, but it's difficult to both enable the tests and have the bug there -- we don't want to forget about it, so maybe it's better to just fix it. * all: remove the duplicate 'the' in annotations (#17509)Wenbiao Zheng2018-08-271-1/+1 | * crypto: change formula for create2 (#17393)gary rong2018-08-141-1/+1 | * core/vm: fix comment typo (#17319)stormpang2018-08-061-1/+1 | | | | antything --> anything :P * core/vm: update benchmarks for core/vm (#17308)Hyung-Kyu Hqueue Choi2018-08-031-0/+4 | | | | | | - Update benchmarks to use a pool of int pools.
