The price of Zcash has recovered nearly 50% from last week’s lows after a proposal for a new network upgrade sought to address concerns raised by a recently disclosed security vulnerability that could have allowed the creation of counterfeit tokens.
summary
- ZEC price rebounded after Zooko Wilcox suggested Ironwood upgrade to verify circulating supply of Zcash.
- Ironwood follows a patched vulnerability that could have allowed unlimited fake ZEC to be generated.
- Developers previously deployed emergency network upgrades, including a NU6.2 hard fork, to fix the bug.
According to Zcash founder Zooko Wilcox, the proposed Ironwood upgrade would give users a way to verify the circulating supply of cryptocurrency by collecting existing balances across active pools once the upgrade is activated.
The proposal appeared days after Shielded Labs It has been detected A serious flaw in Zcash’s Orchard Secure Block, the network’s main privacy-focused transaction system. Following this revelation, Zcash’s market capitalization fell sharply from a peak of $10.48 billion to about $5 billion before rebounding to nearly $7.5 billion, according to CoinGecko data.
Posting on X, Wilcox said Ironwood will allow users to independently confirm the validity of a circulating supply. He added that the upgrade will introduce a new location for users to hold protected ZEC, place restrictions on transactions that may involve counterfeit currencies, and include measures such as AI-assisted security audits to strengthen the code base.
Emergency upgrades addressed the vulnerability
Details released by Josh Swihart, founder of Zcash Open Development Lab, displays The developers had already published a two-stage response before the vulnerability became public.
The first step involved a soft fork that temporarily disrupted Orchard transactions, Swihart said. Keeping technical details private during that period reduced the potential for exploitation while developers worked on a permanent fix.
The second upgrade, known as the NU6.2 hard fork, was activated on June 3 and resolved the underlying issue before Orchard transactions were restored, according to Swihart.
Shielded Labs stated that the flaw could have theoretically enabled an attacker to mint an unlimited amount of counterfeit ZEC. Meanwhile, the organization said it considered previous exploitation unlikely, although it acknowledged there was no cryptographic evidence to confirm the vulnerability was never used.
Since Orchard operates Zcash’s core protected transaction system with zero-knowledge proofs, the inability to conclusively verify whether the flaw had been exploited became a major concern following the disclosure.
Ironwood is seeking to restore confidence in the show
Against this backdrop, Wilcox presented Ironwood as a long-term solution focused on increasing transparency around network supply while maintaining privacy features.
His proposal noted that users will get the ability to check the circulating quantity of ZEC immediately after activation by accumulating balances from active pools.
According to Wilcox, the upgrade timeline is still uncertain and will depend on further development work and community discussions.
Confidence that the vulnerability would never be exploited was also emphasized in Wilcox’s post, although he did not provide conclusive proof.
Development efforts associated with the proposal include several organizations, including the Zcash Foundation, Tachyon Group, Valar Group, and the Zcash Open Development Lab, according to Wilcox.
Market sentiment improved after emergency repairs and the Ironwood proposal. Z Cash (Like you) rose by approximately 6% over 24 hours to approximately $445, while its market value recovered significantly from the levels recorded immediately after the vulnerability was disclosed, according to data from crypto.news.
