Avalanche, a decentralized application (DApp) platform, faced a significant technical disruption affecting the block production of its proof-of-stake (PoS) blockchain. The issue, which occurred on February 23 at 12:02:27 pm UTC, led to block production problems on Avalanche's primary network. This disruption halted the production of blocks on the P-Chain, X-Chain, and C-chain subnets, with the last block being produced over an hour earlier. Avalanche issued an official alert regarding the block finalization stall, stating that developers were investigating the issue, which prevented blocks from being accepted on the Primary Network.
