L’erreur d’un utilisateur de supprimer accidentellement du code dans le portefeuille de crypto-monnaie introduit par Parity Technologies a gelé environ 280 millions de dollars dans ethereum. Le bug affecte spécifiquement les portefeuilles multi-signatures créés avec un contrat numérique après le 20 juillet.
It would seem that issue was triggered accidentally 6th Nov 2017 02:33:47 PM +UTC and subsequently a user suicided the library-turned-into-wallet, wiping out the library code which in turn rendered all multi-sig contracts unusable since their logic (any state-modifying function) was inside the library.
Parity, la société à l’origine de l’erreur, étudie toujours comment corriger le problème. Quant à l’individu qui a déclenché le verrouillage, il prétend être nouveau à Ethereum et a exprimé sur un forum des inquiétudes sur ce qui pourrait lui arriver :
L’erreur est humaine. Celle-ci coûte chère pour quelques lignes de code effacées par erreur.
A user’s mistake of accidentally deleting some code in cryptocurrency wallet introduced by Parity Technologies may have frozen approximately $280 million in ethereum, mostly affecting “multi-sig” (multiple signature) digital wallets deployed after July 20, according to CNBC.
Digital currencies and the wallets that hold them have become an increasingly attractive target for digital pickpockets, resulting in millions of real dollars’ worth of lost currency. A $50 million heist of Ethereum currency last year exploiting weaknesses in the cryptocurrency’s underlying software threatened to break the Bitcoin competitor.
A month or so ago we wrote about the ways you can lose in the cryptocurrency game – through the volatility of its value and through vulnerable exchanges (websites that store your cryptocash) getting hacked. Turns out there’s another way – the digital equivalent of a bank freeze, which in this case was a “wallet” freeze.
Users of popular crypto-currency wallet Parity were left locked out of almost $300m in funds after a user triggered a coding error, it has emerged. The firm deals in ether – the currency traded on the Ethereum blockchain.

Now, some in the Ethereum community are considering the possibility of a risky network split, known as a “hard fork,” to fix it.
An Ethereum user has unwittingly exploited a major wall in Parity wallets which has locked users out of their accounts, potentially freezing millions of dollars’ worth of the cryptocurrency. In a security advisory last night, Parity — the makers of wallet software used to store and trade Ethereum — said the “critical” issue impacts multi-sig wallets.
