Odaily Planet Daily News Polygon Foundation CEO Sandeep Nailwal announced the deployment of a new consensus layer called Heimdall 2.0 this Thursday. He stated that this upgrade would enhance the backbone of the Polygon Proof of Stake (PoS) blockchain, reducing the finality of the blockchain to about five seconds. However, the complexity is extremely high, making it potentially the most complex hard fork to date, thus node operators need to prepare for the upgrade in advance. (Cointelegraph)
