* Resolve harmony-one/bounties#77: Staking precompiles
Create write capable precompiles that can perform staking transactions
Add hard fork logic (EpochTBD) for these precompiles
Tests for new code with at least 80% unit test coverage
Staking library + tests in MaxMustermann2/harmony-staking-precompiles
* Fix small typo in comment
* Run goimports on files to fix Travis
* Do not activate staking precompile on shard 0
* Cascade readOnly to WriteCapableContract
* No overlap in readOnly + writeCapable precompiles
* Use function selector instead of directive
From Solidity, use abi.encodeWithSelector and match it against the
exact ABI of the functions. This allows us to remove the need for
a directive (32) being encoded, and thus saves 28 bytes of data.
* Do not allow contracts to become validators
As discussed with Jacky on #3906
* Merge harmony-one/harmony/main properly this time
* Run goimports
* Update gas calculation for staking precompile
Please see comment in core/vm/contracts_write.go RequiredGas
* Do not allow contract to become validator (2/2)
* Cache StakeMsgs from precompiled transactions
Add the StakeMsgs to ProcessorResult and cascade them in insertChain
* Remove ContractCode fields from validators
Since smart contracts can no longer beecome validators,
this field is superfluous. Remove it from the Wrapper
structure, and do not assign it a value when creating
a validator. Build and goimports checked
* Update comments in response to feedback
(1) Comments to start with function names
(2) Comments for public variables
(3) Comment to match function name RunPrecompiledContract
(4) Clarify that CreateValidatorFunc + EditValidatorFunc are still used
* Fix Travis build by reverting rosetta change
* Add revert capability to 3 staking tx types
- Delegate
- Undelegate
- CollectRewards
* Fix build: Update evm_test for ValidatorWrapper
* Merge main into harmony-staking-precompiles
* Add gas for precompile calls and allow EOA usage
- Each time the precompile is called, charge the base gas fee plus data
cost (if data can be parsed successfully). A gas fee is added to
prevent benevolent contract deployers from subsidizing the staking
transactions for EOAs through repeated assembly `delegatecall`.
- Allow EOAs to use the staking precompile directly. Some changes to
the Solidity library are associated with this change.
- Remove bytes from parsing address, since the ABI unpacks it into an
address format correctly.
- Add or update tests. Test coverage report to be attached to the PR
shortly.
* Run goimports
* Check read only and write capable for overlap
* Handle precompile stakeMsgs for block proposer
The staking precompile generates staking messages which are cascaded to
the block via the EVM in `state_processor.go`. This change cascades them
in `worker.go` to allow block proposers and block verifiers to keep the
same state.
* Run goimports for cf2dfac4081444e36a120c9432f4e..
* Update staking precompile epoch to 2 for localnet
Bring it in line with staking epoch. Change effects all configurations
except mainnet and testnet. `goimports` included.
* Add read only precompile to fetch the epoch num
* Move epoch precompile to 250
* precompiles: left pad the returned epoch number
* chainConfig: check epochs for precompiles
panic if staking precompile epoch < pre staking epoch
* Add staking migration precompile
- Lives at address 251
- Migrates delegations + pending undelegations from address A to B
- Useful if address A is hacked
- Charges gas of 21k + cost of bytes for two addresses
- Does not remove existing delegations, just sets them to zero.
Replicates current undelegate setup
- Unit tests and `goimports` included. Integration test following
shortly in MaxMustermann2/harmony-staking-precompiles
* Migration precompile: merge into staking
Merge the two precompiles into one, add gas calculation for migration
precompile. Move epoch precompile to 251 as a result. When migrating,
add undelegations to `To`'s existing undelegations, if any match the
epoch.
* Add migration gas test, remove panic, add check
In response to review comments, add tests for migration gas wherein
there are 0/1/2 delegations to migrate. Add the index out of bound check
to migration gas calculator and remove panics. Lastly, re-sort
migrated undelegations if no existing undelegation in the same epoch was
found on `To`.
