NEO upgraded its consensus mechanism ahead of the scheduled move to NEO 3.0 in 2020.
Often referred to as โChinese Ethereum,โ the project has been making moves in 2019 to increase its global footprint. NEO recently opened a U.S. officeโNEO Global Development Seattle, led by former Microsoft executive John deVadossโand hosted its second developer conference in the same city.
Part of the process of readying the NEO blockchain for version 3.0 involved updating its Byzantine Fault Tolerance (dBFT) consensus mechanism. The upgrade to 2.0 makes the algorithm more resistant to disruptions and node failures, said a representative from NEO.
Irreversible and unforkable?
Compared to proof-of-work (PoW), the consensus mechanisms used by Bitcoin and Ethereum, where blocks are solved by computers โminingโ blocks, the dBFT mechanism works by using a small group of trusted servers (nodes)โcurrently numbering less than 10โto secure the NEO blockchain.
DBFT ensures transactions made are irreversible and that forks cannot be made to the NEO blockchain. Version 2.0 will โguarantee immediate transaction finality and includes a recovery method to help failed nodes on the NEO network get back online with minimal disruption,โ according to a release from the project.
The new consensus mechanism will also make it so the NEO blockchain cannot be forked, making the system โtruly irreversible.โ The feature is a benefit for enterprise applications of NEO but may pose problems in the future around the decentralization and governance of the system.
According to Erik Zhang, co-founder of NEO and the protocolโs architect:
โWith this improvement, dBFT will have more strict finality. Users only need to wait for one confirmation (15 seconds) to ensure the irreversibility of the transactions and prevent double-spending. This is very suitable for financial applications.โ
NEO 3.0 is on schedule
The upgraded consensus mechanism is just one part of NEOโs roadmap to NEO 3.0, a completely new blockchain which may require users to swap their tokens ahead of the migration. However, detailed release plans are not available yet. Work on version 3.0 is ongoing and NEOโs GitHub page lists the upgrade as 62 percent complete.
At NEOโs 2019 developer conference, Da Hongfei, the co-founder NEO, said he wanted NEO to be the number one blockchain by 2020. NEO hopes 3.0 will make the blockchain ready for large-scale adoption by companies such as Alipay or WeChat.Version 3.0 is expected to launch Q2 of 2020 according to an earlier statement from the project.
