Golang implementation of the TTC protocol.
gttc is base on go-ethereum (v1.8.9), 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 contain 7 files 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
- snapshot_test.go : test for snapshot
- signer_queue.go : calculate the order of signer queue
- signer_queue_test.go : test for signer_queue
- api.go : API
If you familiar with clique, you will find alien like that very much. We also 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 from the snapshot. Code annotation will show the details about how it works.
Current Mainnet and Testnet is deploy the code of branch release/v0.1.7
