I'm pasting here what @cblgh had to say about blobs in cabal:

i don't really remember what the issues we had with blobs was, but here's how you can do some basic stuff with it using sbotcli

[cblgh@howl]$ ./sbotcli blobs --localstore "~/.ssb-go/blobs" add blob-ul.txt
before=blobs locl=null
blobs.add="&skEdYtad6Ytg87x7u0h1LEe29LwUy/MC9oWofg4TUBY=.sha256"

i.e. you gotta pass the --localstore flag, and it has to point to the blobs folder of the running sbot

i.e. if you start a go-sbot with --repo "/var/ssb", then the blobs flag should be --localstore "/var/ssb/blobs", apparently

get works too, but has looks buggy

fixed the apparent error with has, hard to verify with a shitty bot tho ^^. i get what seems like a false negative tho

Further notes from testing:

Once the add command has been executed (documented above), it returns a reference to the blob. This can then be used to compose and publish an about message:

./sbotcli publish about --image "&JlJHc9yeG1EpZA9fIPGLzUKDH0FeR39Ai57euhKT1G8=.sha256" "@Sih4JGgs5oQPXehRyHS5qrYbx/0hQVUqChojX0LNtcQ=.ed25519"

Note that the ordering of the arguments is very important here, as are the inverted-commas (") around the references. The command will fail if the inverted-commas are ommitted.

Further notes from testing: Once the `add` command has been executed (documented above), it returns a reference to the blob. This can then be used to compose and publish an `about` message: ```shell ./sbotcli publish about --image "&JlJHc9yeG1EpZA9fIPGLzUKDH0FeR39Ai57euhKT1G8=.sha256" "@Sih4JGgs5oQPXehRyHS5qrYbx/0hQVUqChojX0LNtcQ=.ed25519" ``` Note that the ordering of the arguments is very important here, as are the inverted-commas (`"`) around the references. The command will fail if the inverted-commas are ommitted.

publishing an about with the image

./sbotcli publish about --image "&skEdYtad6Ytg87x7u0h1LEe29LwUy/MC9oWofg4TUBY=.sha256" "@767fbfkQ7LUyNpXuR4uwvlAry+X8xSJ7CM3nNhjIrwI=.ed25519"

notes:

quotes around base64 input is important
the order of args is important for golang binaries: always, always flags before any final flagless arguments
adjust the blob ref passed with --image to your blob ref from ./sbotcli blobs add :)
