The bitcoin SV price, which hasn't climbed along with bitcoin and other major cryptocurrencies this past year, has lost around 5% since the so-called 51% attack.

Such attacks are attempts by miners that secure cryptocurrency blockchains in return for tokens to overwhelm the network and reorganize the record of transactions, potentially resulting in coins being double spent and destroying their value.

"BSV is going through a massive 51% attack," Lucas Nuzzi, a network data product manager at Coin Metrics, said via Twitter. "After an attempted attack yesterday, some serious hashing power was unleashed today at 11:46AM and attackers are succeeding."

The attack resulted in three versions of the bitcoin SV blockchain being mined simultaneously.

"There was plenty of confusion across mining pools after the attack, but only one (successful) 14-block [reorganization] since the attack began," Nuzzi added.

"In response to the ongoing reorganisation attack on the BSV network, Bitcoin Association recommends that node operators mark the fraudulent chain as invalid," the Bitcoin Association, which manages the bitcoin SV blockchain, said via Twitter. "This will immediately return your node to the chain supported by honest miners and lock the attacker’s chain out."

Bitcoin SV, itself a version of an earlier bitcoin fork called bitcoin cash, was created in November 2018 after developers disagreed over the how to grow bitcoin cash.

"BSV is a threat to other so-called cryptocurrencies because it is doing what bitcoin was always meant to do," a spokesperson for the Bitcoin Association said via email in response to why someone might be trying to "destory" the bitcoin fork.

While bitcoin, the largest cryptocurrency by value with a market capitalization of around $700 billion, has become known as a store of value, bitcoin cash and bitcoin SV are aiming to become global payment networks.

However, both bitcoin cash and bitcoin SV have suffered accusations of centralization, leaving them vunerable to attacks and manipulation.

Bitcoin SV is supported by Craig Wright, the Australian entrepreneur and founder of blockchain developer nChain who claims to be bitcoin's mysterious creator Satoshi Nakamoto. Wright has alientate much of the bitcoin and cryptocurrency community with heavy-handed attempts to be recognized as Nakamoto and lay claim to billions of dollars worth of bitcoin.
