In recent days even if I try to be the fastest in using ViaBTC I still can't. Has ViaBTC really stopped their temporary acceleration?
How to check blocks mined by ViaBTC?
I want to check if they are still taking 100 low fee transactions every hour.
The free tx acceleration is still ongoing, I believe. I had a successful attempt couple days as well but there are some stuff going on that makes it harder to submit a tx e.g. we believe that bots were abusing the free slots hence they get taken fast.
For your 2nd question, most block explorers should do e.g.
https://blockchair.com/bitcoin/blocks?q=guessed_miner(ViaBTC) or
https://mempool.space/mining/pool/viabtcViabtc has also reduced the free slots to 20 -- this will tighen the competition even more, rip.
By the order of submission, ViaBTC supports 20 FREE acceleration chances per hour.
Thanks for the answer and I have also checked some of the blocks generated by ViaBTC and it looks like the free acceleration is still there. It's just that there are only a few slots available which means they run out more quickly in just a few seconds. Because in the Blocks produced by ViaBTC there are still many transactions with small fees which probably come from free acceleration slots and from paid acceleration slots. But most likely come from paid acceleration services.
When I wrote this the fees were still stable for quite a long time in the range of 35 to 40 sats/vB. I think it will be difficult for fees to fall further than this.
