After failing to go live last month, the Cardano (ADA) Vasil hard fork is delayed again as teams behind the Cardano blockchain development target a smooth network upgrade.Input Output Global (IOG), the organization responsible for Cardano’s research and development, released a YouTube update on Thursday on the upcoming Vasil hard fork.IOG technical manager Kevin Hammond announced that the Vasil hard fork will be postponed one more time to ensure that all parties, including exchanges and API developers, are “all ready for that.” Hammond said:“Obviously, from where we are, there could be a few more weeks before we go to the actual Vasil hard fork. […] This is incredibly important. All the users must be ready to progress through the hard fork to ensure a smooth process.”Hammond pointed out that IOG has been focused on solving some testnet issues, progressing with the Cardano node version 1.35.2. The new node version fixes issues related to stake pool operators, decentralized application (DApp) developers, internal testing and other issues identified on the testnet.“The goal is that it will flush out any final issues as we go to the Vasil hard fork. What we’re doing is fixing on testing authority, getting it right and not rushing,” Hammond added.Amid the expected update, ADA price has seen some significant volatility, surging more than 7% over the past 24 hours at the time of writing, trading at $0.537. The cryptocurrency is up 21% over the past 14 days, according to data from CoinGecko.Cardano (ADA) 14-day price chart.
