The public chain project CasperLabs officially launched the incentive test network Zug500, bringing the MVP implementation of the “Highway Protocol”, which is the first pure PoS CBC-Casper version that can verify the activity. The Highway protocol allows all types of participants to join the network. In the first round of Zug500 testing, the official will focus on protocol fine-tuning, community communication and improvement processes. Currently, HashQuark, SNZ Pool, Stake.fish, etc. have joined the CasperLabs testnet verification node.
