v3.0.0

Introduction

In go-nebulas v3.0.0 release, we release Nebulas Voyager version.

Change details

New features

Voyager’s core upgrade is the Proof of Devotion (PoD) consensus mechanism. The PoD mechanism is built on the basis of the contribution size from the community and is a novel method for decentralized collaboration.

The PoD mechanism comprises two components:

• Consensus mechanism: PoD delivers a fully decentralized blockchain relying on community managed nodes for mainnet operation, security and stability.
• Governance mechanism: The consensus nodes which produce the most blocks will be chosen as governance nodes and will decide if community proposals should become projects, funding and more. All governance votes will utilize on-chain voting.

Others

• Adjustment of the event contract address record generated within smart contracts which modifies the binary hex of the smart contract address in topic.
• Security upgrade of the mainnet pertaining to modifications of the blacklist management via smart contract.
