How to use Walrus for storing and verifying data on Solana?
I'm trying to build a Solana smart contract, and I need to hash some data on-chain. I want to store this hashed data using Walrus and verify it later. My main concern is whether to store this data on-chain or off-chain using Walrus. Additionally, I'm curious if storing the data off-chain allows for editing, and I am looking for the most efficient and secure method to enable this validation through the smart contract.

Can I set env vars in a Walrus published site?
I'm trying to figure out if it's possible to set environment variables in a site published on Walrus. The idea is to adjust certain settings dynamically, but I'm unsure if Walrus supports such backend variables due to its static nature. Any insights?

What happens to blobs after they hit the end epoch?
I was wondering what exactly happens to blobs on the Walrus network when they reach their end epoch. Do they just disappear? Or can I get back some of the storage costs if I've marked them as deletable? Also, how does the whole lifecycle of these blobs work, especially in terms of storage reclamation?

What happens to data after the 'end epoch' in Wal framework?
I was learning about the Wal framework's 'writeBlob' function which requires setting a 'start epoch' and 'end epoch'. I'm curious, what happens to the stored data after the 'end epoch' is reached? Does it get deleted automatically, or does something else happen to ensure data continuity?

Can I store NFT metadata and how to fetch it?
I'm working on an NFT project and I'm considering storing metadata for my NFTs. I'm curious if I can store this metadata externally and what the best practices would be for fetching it afterwards. Any advice would be greatly appreciated!

Does deploying a site with Walrus make it live instantly?
I’m trying to wrap my head around deploying a site using Walrus. When I hit the publish button and deploy the site, does it immediately go live, or do I have to wait for one epoch before it appears online?

How can I become a Walrus storage node operator?
I've been keen on becoming a storage node operator for the Walrus decentralized storage network. However, I've read somewhere that the intake for storage node operators happened a while ago. Is there a way for new operators like myself to join, or is it limited to selected developers at this stage?

How to get SUI tokens for testing despite captcha issues?
I haven't been able to get a token due to captcha rate limiting. I sought help by asking if a dev could send me some test SUI tokens. I haven’t claimed anything yet and am unsure why this is happening. Is there a reliable way to access SUI tokens for testing?

Can anyone run a Walrus storage node, or is it restricted?
Hey folks! I'm curious if I can just launch a storage node or if there's some kind of permission or whitelist involved. Anyone knows what the requirements are? Thanks!
