Blockchain data provider Allium has restored data delivery following a security incident. Its October 28 data sharing update indicates that raw and enriched data tables for 18 major chains, including Ethereum, Solana, and Bitcoin, on Snowflake and Databricks have passed integrity checks and are fully operational. However, historical backfills for all chains on BigQuery are still in progress, and API keys have been revoked, requiring users to create new ones and reset passwords. Additionally, new data uploads and access to previously uploaded data remain temporarily disabled.
