Hic et nunc
NFTs are everywhere these days, proof is the success of hic-et-nunc.
The common best practice for NFTs is to store them on ipfs.
So does hic-et-nunc, both for files and their metadata.
Currently, hic-et-nunc uses infura ipfs gateway, that pin files for free, but this may change without warning.
As long as a file is reached by the network, it will be available, but there’s a chance that this file will not be available one day, due to the garbage collector.
An IPFS node allow to pin files so that they won’t be garbage collected.
There are some free services like Pinata, with low prices when we want to have more storage.
Because last week-end, thanks to the #OBJKT4OBJKT event I grabbed a lot of NFT (the event is still ongoing), I wanted to take my responsibility for pining the NFTs I collected.
I took a server a while ago, it currently runs the 2 Tezos testnets (current and next), and this hugo blog.
So I’m left with a lot of free resource, because of the low power consumption of the blockchain, and I choosed to install an ipfs node to pin my collected NFTs.
IPFS Node Install
To install ipfs, I followed the instructions here
Then I created an ipfs user and initiated the server config.
sudo useradd --create-home -s /bin/bash ipfs sudo su ipfs cd ipfs init --profile server
After that, I configured a systemd service, just adapting the official instructions to my use case.
# /etc/systemd/system/ipfs.service [Unit] Description=IPFS daemon After=network.target [Service] User = ipfs Group = ipfs WorkingDirectory = /home/ipfs/ ExecStart = /usr/local/bin/ipfs daemon Restart = on-failure [Install] WantedBy=multiuser.target
The usual system restart:
sudo systemctl enable ipfs.service sudo systemctl daemon-reload sudo systemctl start ipfs.service
Now I can just run
ipfs pin add <hash>
Next step I plan to do is a small web ui around ipfs HTTP api.
