Hash War: SV Chain Block ReOrg ‘Attack’ Under Way

Hash War: SV Chain 18 Block ReOrg Attack Under Way

“18 block re-org on SV,” Olivier Janssens from freesociety.com announced. On second inspection, it appears the ReOrg was only two blocks, but happened 18 blocks ago. “A perfect false flag operation to prevent exchanges from accepting SV deposits to prevent any dumping. If this was a real attack, the re-org would have been much longer,” he mused. It’s the latest wrinkle in the Bitcoin Cash (BCH) Hash War, as Day 4 promises even more twists and turns.

Hash War Day 4 Sees SV Chain Under ReOrg Attack

Conspiracy theories are coming fast and furious. It appears the ReOrg was only two blocks, but happened 18 blocks ago. Sources familiar with the ABC camp and its associations confirm the rival development team awarded by most exchanges with the BCH ticker is not involved with the SV ReOrg as of this writing.

The BCH scheduled upgrade for 15 November 2018 quickly turned into a contentious hard fork, as at least two development teams campaigned for their respective implementations.

The BCH chain split into two coins, Bitcoin Satoshi’s Vision (SV) and Bitcoin ABC (ABC). SV partisans renamed the pending affair a Hash War to be fought by mining pools, vowing to end Bitcoin ABC (ABC) once and for all, halting all BCH transactions and bankrupting associated companies if need be.

Stress Test? False Flag? Mistake?

At day 4, it appears the SV chain is under ReOrg attack. Telegram chat groups went into overdrive, as comments zipped along: “One branch is 2 deep the other 18,” one enthusiast noted. “The same miner found the two 301 blocks on the two chains 😵. It could be SV did this accidentally to themselves.”

A ReOrg attack in this instance is when enough hash is gained to mine blocks faster than the chain’s miners (those interested in keeping the system running well). The ReOrg attacker, at least in theory, is able to roll back blocks and publish their own.

Still others maintain it was the SV side’s own doing, as one source explained, “If the attack was serious, I’d imagine it would be more blocks than it is. The chain is a bit young to be twisting it intentionally, especially on mainnet. Satoshi’s Shotgun makes relaying of big blocks for the SV client very difficult.”

As Jonathan Toomim noted, so far the community believes it to be a simple mistake. “It is not my belief that this chainsplit was due to malicious miner activity. I believe this happened on their own due to poor management of the stress test transactions.”

An SV supporter shrugged it all off, insisting, “That was a 2 block orphan, it’s not unusual with big blocks.” The chain’s chief scientist had a similar reaction, “FUD and PoSM.”
