RE: Hive API Node for under $750 - Hive can scale at very low cost.

in #witness3 years ago (edited)

BLURT can run on much a less, in fact a Raspberry PI! A lot cheaper, and a lot smaller footprint!

With thousands of Raspberry Pi node users around the world, that would be a better idea for a more decentralized social platform. Can Hive upgrade to do this too I wonder?

No it can't. Not since it was spammed and is now over that threshold.
(There is a post about this by the Blurt dev, they are building a new chain now)

They also started the chain from scratch, if Hive didn't bring over state, it would be able to as well.

Raspberry Pi's IO poor, especially to SD card.
Did Blurt ditch the Steem blockchain history?
The Hive blockchain is 330Gb - not something that a rPI can handle.
If Blurt is successful it will end up with a very large chain too.

What code changes did Blurt make to be able to run a node on an rPI?

Raspberry Pi's are atrocious at SD IO, the Pi 4 made a big improvement, but it is still bad, especially if you don't use a Samsung EVO+ (the best performing SD card by a long shot on a Raspberry Pi).

But anything serious I'd highly recommend just using an SSD drive, you can get one for about $30 and be 100x faster.

Some tests I did. Using something other than a Samsung EVO+ would have been much worse.

Maximum performance out of the Raspberry Pi 4 with an SSD drive

I'm planning to run the jussi for my API node on a Raspberry Pi 4 with 4Gb RAM and SD card.

Is this sufficient in your view or should I add a SSD on USB?

I have both the cable and SSD drive but understood jussi just used RAM for cache and didn't really do IO.

It will mostly be cpu/ram so I don't see a huge difference /w SD vs SSD outside of management time (and reliability on power outages as SD corrupt easier).

You can get a 250G SSD and cable for around $40.
