Verify a decision

Every moderation decision on AVOID.NET is anchored to the Solana blockchain. You don't have to trust us — you can verify cryptographically that we committed to a verdict at a specific moment and have not rewritten it.

How verification works

  1. We commit. When a moderator accepts/rejects a submission, we serialize the decision into deterministic UTF-8 bytes (payload_canonical_string), hash it with SHA-256, encode the digest as base58, and write it to Solana inside an SPL Memo v2 transaction.
  2. We store the bytes. The exact bytes we hashed are stored alongside the decision in our database. Anyone can read them and recompute the hash in any language.
  3. You compare three values. Database hash, your independently-recomputed hash, and the hash inside the on-chain memo. If all three match, the decision is authentic and timestamped.
The on-chain memo format is AVOID.NET|v1|h:<b58-sha256>|d:<id>|t:<iso>

Find a signature on any investigation page's decision log, or run python -m src.verify_decision --signature <sig> for a CLI check.

ecosystem) and later expanded to Sei and Injective. In December 2023, the protocol suffered a confirmed oracle-manipulation exploit spanning 13 days that drained approximately $1.14 million (roughly 10% of liquidity provider funds). The protocol subsequently underwent a strategic rebrand and token migration into the Rujira (RUJI) ecosystem in 2025, effectively sunsetting the standalone LVN token.","timeline":[{"date":"2021-01-01","event":"Levana Protocol founded; originally developed on Terra blockchain.","source":"Reflexivity Research — Levana Finance Overview","source_url":"https://www.reflexivityresearch.com/free-reports/levana-finance-overview"},{"date":"2023-03-06","event":"FYEO Inc. begins security assessment of Levana Perps contracts.","source":"Levana Protocol Medium — FYEO Audit Summary","source_url":"https://medium.com/levana-protocol/levana-perps-passes-security-audit-by-fyeo-a-comprehensive-summary-of-the-audit-report-fec50fa73c18"},{"date":"2023-07-01","event":"Levana launches mainnet beta on Osmosis blockchain.","source":"Reflexivity Research — Levana Finance Overview","source_url":"https://www.reflexivityresearch.com/free-reports/levana-finance-overview"},{"date":"2023-12-13","event":"Oracle manipulation exploit begins on Osmosis; attacker starts draining Levana liquidity pools.","source":"REKT News — Levana Protocol","source_url":"https://rekt.news/levana-rekt"},{"date":"2023-12-17","event":"Concurrent DDoS attack on Levana backend infrastructure begins, hampering detection and response.","source":"SiliconANGLE — Levana Protocol exploited for $1 million+","source_url":"https://siliconangle.com/2023/12/28/blockchain-based-levana-protocol-exploited-1-million-crypto-hack/"},{"date":"2023-12-18","event":"LVN token launches on mainnet with 70 million tokens issued at genesis.","source":"CoinMarketCap — Levana Protocol","source_url":"https://coinmarketcap.com/currencies/levana-protocol/"},{"date":"2023-12-26","event":"Exploit becomes visible as network congestion amplifies losses.
