It’s just a benchmark. No funds are needed/used. Run zcash-cli zcbenchmark createsaplingspend 5 for the first metric and zcash-cli zcbenchmark createsaplingoutput 5 for the other one. 5 is the number of runs that you can average out so the more the merrier but I got pretty consistent results.
You need to cross-compile still it’s just now you don’t have to checkout a different repo/branch but can do directly from the Zcash repo and master branch.
What prevents us from putting the blockchain data available for download as well? I wonder if that could avoid the syncing time issue and requiring extra ram not needed when synced…
I thought of some companies were selling hardware running bitcoin node including the full blockchain…
We’ve now added the option to resync from Casa, which downloads the chain from Casa’s Bitcoin node. This is much faster than syncing from scratch (it takes about half a day), but it does require trusting Casa’s blockchain data. It’s the same level of trust you put in Casa when we presync the node before sending it to you. As always, there is the option to sync from scratch for users who want to verify the entire chain themselves.
There’s also the more practical issue of the cost of hosting something like that as the chain is over 20GB so that soon adds up.
Updated for the Nvidia Jetson Nano. I managed to sync from scratch with this but it wasn’t great. It runs a custom spin of Ubuntu 18.04. Syncing was slow and I had one out of memory error. I didn’t configure any swap but due to low memory, it was swapping out to the SD card which was obviously terribly slow. I tweaked the swappiness value via sudo sysctl vm.swappiness=0 which helped complete the sync.
Unless you have specific needs for the Nvidia, I’d probably recommend the Odroid N2 or Pine64 RockPro (4GB) for the best out of box experience for a zcashd node with the Odroid the slight performance winner.
My Pi4 just arrived but it looks like there aren’t any 64-bit OS for it yet so will have to wait - it seems a few are “coming soon” like Kali Linux and Ubuntu Mate but I couldn’t find any currently available.
