BitMEX Research has identified a suspicious dual-use transaction worth 0.00062063 BTC, or roughly $ 21 – and this doesn’t sound like a popular swap wallet hack.

On January 20, BitMEX’s ForkMonitor noted that “several blocks were produced at 666833.” BitMEX Research Tweets:

An hour later, BitMEX Research attributed the lost block to an RBF transaction and replaced the unconfirmed transaction with a new transfer with higher fees. Since then, however, ForkMonitor has updated its advice: No Injury Detected (RBF).

Twitter user and Australian lawyer BSV Eli Afram referred to “mixed messages” from BitMEX Research, arguing that the dual-use transaction should be a concern despite its low value:

So it looks like there was a real double account on BTC … not an RBF (exchange of fees), but a real double account. Only $ 22 … BUT – it could be $ 22 million. ”
Bitcoin White Paper Satoshi Nakamoto is credited with solving the double spending problem in 2009. The challenge of ensuring that the decentralized network can independently verify that the same coins have not moved more than once has thwarted previous attempts to get digital money.

In July, crypto security company ZenGo discovered a dual-use vulnerability targeting many popular Bitcoin wallets. As wallet manufacturers began to tackle the vulnerability, Bitcoin Cash spokesman Hayden Otto warned that the vulnerability could be rooted in BTC’s compensation function. Previously, he used the same vulnerability in a viral video.
