Bitcoin SV [BSV] was in the limelight because of its touted large blocks, especially the 128MB blocks, highlighted by its spearheads. Just weeks after the feat, the coin’s blockchain was subjected to multiple block reorganizations as pointed out by a series of April 19 tweets by BitMEX Research.
The tweets indicated that on April 18, the exchange’s BSV node saw dual block reorganizations. BitMEX stated:
“First a 3 block re-organisation, followed by a 6 block re-organisation.”
BitMEX cited block 578639 as the location of the split, where the two competing chains were noticed. The tweet further stated that the exchange’s note kept track with the chain on the left until block 578642, following which it moved to the right. In the next hour, there was another jump to the left.
The research, however, contends that all the Transactions IDs [TXIDs] from the aforementioned fork migrated to the main chain, hence, double spending can be ruled out.
In light of this reorganization, BitMEX stated that the inference drawn can be that the BSV network cannot be relied on for payments, the block size touted to be too large to handle, and the network latency was too high.
With the BSV network incapable of handling a block of such a size, as the research indicates, their touted goals seem far-fetched. The cryptocurrency’s camp has maintained that their intention was to raise the default block cap to 512MB, with the same to be raised to 1-2GB in the future.
Jimmy Nguyen, one of the leads of the BSV project has even suggested blocks with no specified limits, with the same configured by the miners.
Block size apart, Bitcoin SV has been going through a tumultuous period off-late. The coin has been subject to a number of delisting announcements from top exchanges following the legal challenge mounted by its founders, which some have compared to “bullying”.
