* core: fill in genesis timstamp and remove dMoment from protocol handshake (#263)Wei-Ning Huang2019-04-091-0/+10
| | | | | | Fill in dmoment as genesis block timestamp. This allow us to remove dMoment check from protocol handshake since genesis block hash itself will protect us against different dMoment.
* core: vm: remove delegation mechanism (#245)Wei-Ning Huang2019-04-091-1/+1
| | | | | | | | | | | | | 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.

* core, consensus: pluggable consensus engines (#3817)Péter Szilágyi2017-04-051-2/+2
| | | | | This commit adds pluggable consensus engines to go-ethereum. In short, it introduces a generic consensus interface, and refactors the entire codebase to use this interface.
* core: refactor genesis handlingFelix Lange2017-03-231-0/+161
This commit solves several issues concerning the genesis block: * Genesis/ChainConfig loading was handled by cmd/geth code. This left library users in the cold. They could specify a JSON-encoded string and overwrite the config, but didn't get any of the additional checks performed by geth. * Decoding and writing of genesis JSON was conflated in WriteGenesisBlock. This made it a lot harder to embed the genesis block into the forthcoming config file loader. This commit changes things so there is a single Genesis type that represents genesis blocks. All uses of Write*Genesis* are changed to use the new type instead. * If the chain config supplied by the user was incompatible with the current chain (i.e. the chain had already advanced beyond a scheduled fork), it got overwritten. This is not an issue in practice because previous forks have always had the highest total difficulty. It might matter in the future though. The new code reverts the local chain to the point of the fork when upgrading configuration. The change to genesis block data removes compression library dependencies from package core.
