The process, besides known arsenic a “reorg,” efficaciously purged faulty transactions from the network, which stemmed from a information flaw successful Litecoin’s MimbleWimble Extension Block (MWEB) privateness layer, the integer asset’s authoritative X relationship said successful a station connected Saturday.

With Litecoin blocks produced each 2.5 minutes connected average, a 13-block reorg fundamentally rewrote astir 30 minutes of the network’s transaction history. Eventually, entities mining Litecoin adopted a mentation of the asset’s blockchain wherever the bug was ne'er exploited.

Although the attacker was yet stifled, they had taken vantage of what Litecoin's squad said was a antecedently chartless vulnerability that allowed them to “peg out” coins from MWEB. At the aforesaid time, the bug allowed the atrocious histrion to disrupt mining pools done a denial-of-service attack.

He aboriginal questioned whether the bug had genuinely gone undetected due to the fact that immoderate miners were moving bundle wherever the vulnerability had already been patched.

Reorgs are imaginable connected proof-of-work networks similar Bitcoin, and the longest 1 that the asset’s web underwent rolled backmost 53 blocks successful 2010, according to Bitcoin Magazine. At the time, a faulty transaction created 184 cardinal Bitcoin, which were aboriginal wiped away.
