As darkfi does not yet have real life usage (and may never have after Amir Takii turned out to be a mossad asset via Epstein-files), the next best thing is monero (XMR), which you can buy/sell/trade on a DEX , P2P, nokyc, multisig escrow, very low fees, very low minimums: dawnswap.com

PS: a new version has been released (1.2.3) with even lower fees (maker 0% - taker 0.4%)

hi, would having the blockchain (pruned or unpruned) on a cifs attached storage device ben dumb?

really wanna contribute a node but dont have too much storage on my server, but i do have a cifs-mounted storage device

The fs must support mmap. Reasonable random i/o performance is also needed.
