Go dpeth

Golang implementation of the dpeth protocol.

dpeth is base on go-ethereum, the main part be modified is in consensus directory. We add a new consensus algorithm named alien in it.

Alien is a simple version of DPOS-PBFT consensus algorithm, which in consensus/alien:

• alien.go : Implement the consensus interface
• custom_tx.go : Process the custom transaction such as vote,proposal,declare and so on...
• snapshot.go : Keep the snapshot of vote and confirm status for each block
• signer_queue.go : calculate the order of signer queue
• api.go : API
• cross_chain.go : Cross chain communication by custom transaction

Alien use header.extra to record the all infomation of current block and keep signature of miner. The snapshot keep vote & confirm information of whole chain, which will be update by each Seal or VerifySeal. By the end of each loop, the miner will calculate the next loop miners base on the snapshot. Code annotation will show the details about how it works.

• Current Mainnet and Testnet is deploy the code of branch release/v0.2.0
• Next version will be release on July 12, which contain the hard-fork at block height 2968888
• Please make sure your node upgrade to release/v0.2.0 before that block height.(before July 17,2019 UTC/GMT+8)

More information about this upgrade will be found UPGRADE TO dpeth V0.2.0
