- Buzz about a potential “double spend”—a potential flaw in the blockchain—sent the price of Bitcoin down 11% yesterday.
- The software company NexTech AR Solutions sold off all its Bitcoin as a result.
- But analysts say the “double spend” never happened at all.
A double spend happens when a blockchain processes the same data in two blocks—a potentially system-busting failure. Since faith in cryptocurrencies depends so much on the security of these impartial, decentralized systems, a single flaw can have far-reaching consequences for the market.
But analysts are suggesting the rumored “double spend” never happened at all.
BitMEX Research, the analytics blog for the BitMEX exchange, tweeted on Wednesday about the possibility of a “small double spend of around 0.00062063 BTC ($21).” CoinTelegraph then followed it up with a short piece titled “Bitcoin Double Spend Spotted in the Wild,” which appears to have worried some investors: the price of dipped 11%, and remains in the low $30,000s.
According to reports, BitMEX Research’s “stale” block may have just been the product of a routine split in Bitcoin’s blockchain, also known as a block reorganization. This would mean no Bitcoin was actually spent twice, and that the blockchain remains uncompromised.
An explainer from the pseudonymous blockchain researcher Hasu concludes that “we can know with very high certainty that the funds did reach their target destination and were not, in fact, double-spent.”
NexTech is a software company that’s ignored the warning signs and followed the market to an extreme, dumping its entire Bitcoin stash in the wake of the initial “double spend” rumor. Evan Gappelberg, NexTech’s CEO, commented on the sell-off in a statement:
“This sale reflects our awareness that something potentially has changed with Bitcoin… If the system is built on scarcity and faith in the system, then a ‘double spend’ would eliminate both—essentially destroying the store of value it was meant to be. In light of this potential outcome, I have decided to move to cash as this story is still unfolding.”
Whether or not there’s any real reason for those concerns, NexTech is out of the game.
