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.

Industry reporting describes Nethermind and WebN as remaining majority shareholders in the venture. Twinstake's team page identifies Tomasz Stańczak, also the founder and chief executive of Nethermind, as a founder of Twinstake, though sources disagree on whether he currently holds the title of chief executive or chairman of Twinstake's board. The company is reported to be registered as Twinstake Ltd. in the Cayman Islands, with a UK operating entity (Twinstake UK Limited) used in some job postings. In February 2026, CoinDesk reported that WebN Group was closing after what a source described as having 'successfully completed its mission'; WebN's portfolio was reported to include Twinstake, KAIO, TruFin and Geometry. The reporting states the closure was not expected to affect Howard's broader digital-asset interests, but available sources do not clarify what became of WebN's equity stake in Twinstake after the wind-down.","heading":"Corporate structure and ownership","severity":"low","sources":[{"credibility":2,"name":"Nethermind fintech profile (FinTech Scotland)","type":"other","url":"https://www.fintechscotland.com/fintech/nethermind/"},{"credibility":2,"name":"Billionaire Alan Howard's crypto incubator WebN closes down (CoinDesk, via MEXC republish)","type":"news_article","url":"https://www.mexc.com/news/797882"},{"credibility":3,"name":"Twinstake Ltd. partner listing (Web3Connect)","type":"other","url":"https://web3connect.com/partner/twinstake"}]},{"content":"Twinstake describes itself as a non-custodial staking provider for institutional clients, offering an API for programmatic staking, a 'concierge' staking service with dedicated customer support, and a reporting portal. Clients are said to retain control of underlying assets by staking through their own custodian or wallet provider rather than transferring assets to Twinstake. The company has announced integrations and validator-set memberships across a range of proof-of-stake networks, including joining the IOTA Genesis validator set (2025), partnering with Utila to offer TON staking (December 2024), being added as a staking provider to Virtune's crypto exchange-traded product programme (July 2026), offering staking for Radix (XRD), and participating in Jupiter's jupSOL validator set on Solana. In 2025, Nethermind and Twinstake proposed migrating roughly 7,400 Nethermind-operated validators from Lido's Curated Set to Twinstake, a move consistent with Nethermind's reported shareholding in Twinstake.","heading":"Business operations","severity":"low","sources":[{"credibility":2,"name":"Institutional-Grade Staking: Twinstake Joins IOTA Genesis Validator Set (Crowdfund Insider)","type":"news_article","url":"https://www.crowdfundinsider.com/2025/04/238254-institutional-grade-staking-twinstake-joins-iota-genesis-validator-set/"},{"credibility":2,"name":"Digital Assets: Utila and Twinstake to Enable Institutions with TON Staking Solutions (Crowdfund Insider)","type":"news_article","url":"https://www.crowdfundinsider.com/2024/12/234029-digital-assets-utila-and-twinstake-to-enable-institutions-with-ton-staking-solutions/"},{"credibility":2,"name":"Virtune adds Twinstake as an Additional Staking Provider within its Crypto ETP Programme","type":"news_article","url":"https://www.placera.se/pressmeddelanden/virtune-hyperliquid-etp-virtune-adds-twinstake-as-an-additional-staking-provider-within-its-crypto-etp-programme-20260714"},{"credibility":2,"name":"Twinstake now offers institutional staking of Radix (XRD)","type":"official","url":"https://twinstake.io/news/twinstake-now-offers-institutional-staking-of-radix-xrd"},{"credibility":2,"name":"Nethermind NO Curated Validator set transfer to Twinstake (Lido Research Forum)","type":"community_report","url":"https://research.lido.fi/t/nethermind-no-curated-validator-set-transfer-to-twinstake/10288"}]},{"content":"A third-party validator-slashing dashboard (kjnodes.com) lists two penalty events in late 2024 attributed to a Twinstake-operated validator on the MANTRA chain: an approximately 4,000 MANTRA penalty recorded around October 2024 (logged as the validator's first offense) and a substantially larger penalty of approximately 35,873 MANTRA recorded around November 2024 (logged as a second offense). No independent news coverage, blockchain explorer confirmation, or statement from Twinstake addressing these events was found, and the dashboard does not specify whether the penalties resulted from downtime, double-signing, or another cause.
