103MB block! Looks like Bitcoin Unlimited's trail-blazing improvements and optimisations from the Gigablock project are being usefully deployed into the SV software.
Really
@solex, do you have firm indications of this? I have none.
Their SV software github has been dormant for a month, and they didn't propagate their transactions through their network, but selfish mined that block within some pool.
I don't think there are many improvements needed to selfish mine a 103GB block on the ABC side of the software. Certainly nothing from BU.
Back in 2017, I reg-test mined a sustained sequence of blocks, increasing size by 1MB per block, on an early ABC version. I got up to a maximum of 135MB. Sustaining validation and storage of blocks in the range of 100MB would have been easily possible from an internal POV, on a capable machine.
Organically propagating larger blocks and their transaction traffic is obviously a different matter, and their test showed that again, their network suffered orphaning and downstream breakdowns as a result of being unprepared for such large blocks.
If they were actually using BU improvements, they might have been able to propagated their test transactions without the need for selfish mining.
