In the latest privacy transaction pool of Zcash, Orchard, it is theoretically possible to infinitely forge ZEC (counterfeit currency), and due to Orchard's privacy protection, it is almost impossible to detect the counterfeit on the chain. Orchard was launched in 2022 and was only discovered on May 29, 2026. It was repaired through an emergency network upgrade on June 1-2. Has anyone already fabricated it? It is very dangerous, but the Zcash team (Shielded Labs) believes that there is a high probability that no one will successfully exploit it for three reasons: This bug has been hidden for 4 years without being discovered, indicating a high threshold. 2. They took the initiative by hiring skilled personnel and using the latest AI to proactively search for them, rather than waiting for hackers to come. 3. After discovery, the response was extremely fast, and the vulnerability was blocked within a few days. However, due to Orchard's privacy characteristics, it is impossible to prove 100% with cryptography that no counterfeit currency has been created in the past, which is the biggest uncertainty. Current processing: Fixed: An emergency network upgrade has been performed, and Orchard transactions have returned to normal. The next step is to prepare for another network upgrade, allowing anyone to publicly verify that the total supply of Zcash is genuine and no one is secretly printing more money. The specific plan is to open a new pool and conduct a turnstile accounting check on the coins coming out of Orchard.
