Litecoin Confirms Zero-Day Bug Caused 13-Block Reorg, Network Patched and Stable
Key Takeaways: NEAR Intents had originally reported approximately $600,000 in exposure, saying its team would cover any user losses. With Litecoin confirming the invalid transactions were reversed and wiped from the main chain, the actual settled losses may be significantly lower than initially reported. NEAR Intents has not yet issued a follow-up statement addressing the updated picture. Other cross-chain protocols that accept LTC and paused activity in response to the incident are also expected to reassess their exposure now that the Litecoin team has clarified the sequence of events. To many, the incident highlights a real vulnerability in proof-of-work networks that run nodes on older software versions. Non-updated nodes processed a transaction they should have rejected, which gave the MWEB exploit its opening. “This isn’t an isolated incident. There have been many of these rollback-and-double-spend attacks against Proof-of-Work-alone blockchains both years ago and recently, including recently against Monero and Grin,” Zcash founder Zooko Wilcox wrote on Saturday. This story is still developing.About Author
