P2WSH · reuse-exposed

P2WSH addresses hide the pubkey behind a SHA-256 + RIPEMD-160 hash UNTIL the first outgoing spend, which reveals it in the signature script or witness data. This address has been spent from, so its pubkey is permanently on chain. Every subsequent UTXO at this address is just as exposed as the moment of first spend.

First revealed at block 615,679 on 2020-02-02 (p2wsh_redeem_reveal).

Bitfinex (cold wallet, ChainQuery-attributed)

P2WSH cold wallet attributed to Bitfinex by ChainQuery, currently holding ~130,010 BTC (rank #4 on our rich list). Attribution based on operator analysis: balance scale, address-shape patterns consistent with Bitfinex's known multisig cold-custody scheme, and correlated movement timing with Bitfinex hot-wallet activity. Provenance: MEDIUM, in-house cluster analysis without direct operator self-disclosure. If Bitfinex publishes a proof-of-reserves that contradicts this, label will be revised.
