Zcash Ironwood upgrade: What's changed after the Orchard bug?
Zcash has completed its Ironwood network upgrade, replacing its vulnerable Orchard shielded pool with a formally verified alternative designed to prevent undetectable counterfeiting while beginning the migration of shielded funds into the new pool. According to Project Tachyon and the…
Zcash Loses $470 as Ironwood Upgrade Fails to Lift the Price
Key Takeaways Ironwood closes a supply-verification gap. Spot and futures flows remain negative. The nearest support sits at $450. Losing $450 would expose $419. The Flaw Ironwood Was Built to Close Developers found a soundness flaw in the zero-knowledge circuit behind Orchard, Zcash’s shielded pool. In theory it allowed counterfeit ZEC to be created without detection. The patch shipped in June, and no evidence of exploitation surfaced. Proving…
The Zcash network has today activated the Ironwood update, a critical patch that completely blocks the Orchard privacy pool, where 3.76 million ZECs are accumulated (about $1.89 billion at the current price). The motive: a mathematical failure that, in theory, could have allowed an attacker to create fake coins without anyone noticing it. The bug, found by Taylor Hornby of Shielded Labs in May, affected the Orchard privacy pool. The failure allo…
CoinStats - Zcash says Ironwood proof rules out undetecta...
Zcash researchers published more than 2,700 machine-checked theorems designed to rule out undetectable counterfeiting bugs in Ironwood.Zcash researchers have completed formal verification of Ironwood, publishing a machine-checked proof that the network’s new shielded pool does not contain undetectable counterfeiting bugs under its stated cryptographic assumptions. On Tuesday, Project Tachyon said that the proof, written in the Lean programming l…
