ABC chain is currently 70+ blocks ahead of SV, but why SV blocks are way bigger than ABC blocks in size? Most ABC blocks are no more than a few KB, while SV blocks are several MBs.
I think SV is doing a stress test to prove a point that they can make large blocks. They are not organic TXs from users. In fact they might not even be propagated, but directly mined.
Blocks on BSV chain are filled with stress-test txs that are generated on the spot. Likely for several reasons, but one of them is competitive edge over independents
