[dryrun] Manual test on Delegation and Undelegation

1. Step 1: New Delegation (Passed)

Use an existing validator in shard 0

$ ./hmy --node=https://api.s0.dry.hmny.io blockchain validator information one1sgcpjc405ueglhp5udsskjxcn8crrc2lmuf35c

# 3948 test log

Since the singleflight solution might cause memory leak, swithed the solution to lur.Cache. Do the test again.

Steps and target please see this gist

1. Test Logs

  • Shard 0 validator (localhost:9502): PASSED
  • Shard 1 validator (localhost:9503): PASSED
  • Explorer S0 (localhost:9099): PASSED
  • Explorer S1 (localhost:9099 with script update): PASSED

Feature to be tested

After starting with port other than 9000, node is still able to sync to latest block.

Steps

  1. Set up accounts and test keys
  2. Run node with command which connect to mainnet and run on port 9002.

#3071_test_log

Feature to be tested

During synchronization process, the client node will ask some of the DNS nodes instead of all of them.

Steps for test

  1. Add some print message in function node.forEachPeer to print out all the nodes being used.
  2. Start node.sh to join mainnet with the customized binary file.
  3. See the log for intended message. Shall see number of DNS nodes being queried shall be 4 for beacon.

# Ethereum Sync Logic Analysis

Ethereum Sync Logic Analysis

by Jacky@Harmony 5/20/2020

Description

This document analyze the Ethereum synchronization logic. The analysis is based on go-ethereum commit hash 65ce550b37670ce34aeaeaa6e66510028d2f7603 to the time of this document being written.

Harmony fast sync research

HMY consensus walk through for fastSync

Description

In order to refactor the syncing module of the harmony code, several questions need to be answered:

  1. What is the current network structure?
  2. What is the role of crosslink in block header/body verification?
  3. What is the role of view change in block header/body verification?
  4. What is the role of slashing and how it interact with offchain data?

Blockchain is a chain of blocks. Each block has a certain state to preserve all account data under that block. For example, account balance, nonce, code, storage.
