* test: make StateChangeRequest broadcast-able (#305)Mission Liao2018-11-075-278/+445
| | | | | | | | | | | | | | | | | | | | | | | | | Make `test.StateChangeRequest` behaves like tx on ethereum: - Can be broadcasted and cached in a pool. - Uniquely indexed, and be removed after applied. Changes: - Make cloneDKGx functions in test.State as utilities. - Add hash and timestamp fields to test.StateChangeRequest. - Add two methods to test.State: - PackOwnRequests would pack all pending change requests owned by this instance as byte slice, and move them to global pending requests pool. - AddRequestsFromOthers would add pending change requests from others to global pending requests pool. - The method State.PackRequests now would pack requests in global pending requests pool. - The method State.Apply would remove corresponding StateChangeRequest by hash.

|
* core: refactor witness data processing flow (#124)Wei-Ning Huang2018-09-2010-33/+133
| | | | | | | | | | | Since witness data need to include data from application after it processed a block (e.g. stateRoot). We should make the process of witness data asynchronous. An interface `BlockProcessedChan()` is added to the application interface to return a channel for notifying the consensus core when a block is processed. The notification object includes a byte slice (witenss data) which will be include in the final witness data object.
* core: add blockpool (#121)Mission Liao2018-09-205-22/+190
| | | | | | core.blockPool is used to cache blocks arrived out-of-order. Our consensus should retry those blocks after their acking blocks added to lattice.

|
* core: add blocklattice (#117)Mission Liao2018-09-202-0/+992
| | | | | | | | | | | | | blocklattice is used to replace reliable broadcast. Aiming to fix these problems: - The mechanism related to strong ack is no longer required. - The sanity-check of one block would be passed even if its acking block doesn't exist. This commit doesn't include logic to handle out-of-order blocks. It should be done in another PR.

| | | | | Since we have a bunch of static configurations in the governance contract, instead of using a Get* method for each of them, we instead implement a GetConfiguration() method to return a structure of the configurations.
* bin: allow non-root homebrew install to work (#113)Wei-Ning Huang2018-09-183-0/+41
| | | | | | | | In order for non-root homebrew install to work, we need to setup some custom CFLAGS and LDFLAGS variables, we also need to patch the mcl library so we are able to build. A PR is sent to the mcl upstream, the local patch will be removed once the upstream PR is merged.
* core: remove ticker parameter from NewConsensusMission Liao2018-09-1810-53/+113

The peer discovery is simulated by a hosted server: every peer sends its address to a known server. Once collecting enough peers, respond the whole peers lists to all peers.
