The Anthropic zeta paper proved 67.25% of Riemann zeta zeros are simple and on the critical line. The community has been tightening it since: 67.30%, then 67.3138%.
GPT-5.6 Sol Pro managed to improve the lower bound: 67.3206%.
The proof uses a local inequality on seven consecutive zeros, with a small "pressure" penalty on each of the six gaps.

There was an attack against the ZetaChain GatewayEVM contract today that impacted the internal ZetaChain team wallets only. We've already blocked the attack vector so no more funds can be compromised and will be releasing a detailed post mortem after we have completed our investigation. As a precaution cross-chain transactions are currently paused on ZetaChain.
Investigation is still ongoing and at this time no user funds were impacted by this attack. The current status can be tracked at
On Apr 27, ZetaChain experienced a targeted exploit involving deliberate preparation, including Tornado Cash funding and wallet address spoofing.
Cross-chain ZETA transfers were not affected.
No user funds were affected — all impacted wallets were ZetaChain-controlled.
A Mainnet patch has been deployed, and cross-chain TXs will be re-enabled after continued monitoring.
The exploit affected specific GatewayEVM arbitrary-call functionality, resulting in ~$334K in losses across 4 connected chains.
ZetaChain’s long-term roadmap, mission, and commitment to the ecosystem remain unchanged.
