As data gradually evolves into the core production factor of the digital economy, traditional centralized storage models are becoming increasingly incompatible. The Walrus protocol was born out of this market demand — it builds a complete system on the high-performance Sui blockchain that combines storage, privacy, and programmability.

Calling it a storage tool would be an understatement. Walrus's true ambition is to create a comprehensive ecosystem for decentralized storage and data applications.

**A Leap in Storage Efficiency**

The biggest technical breakthrough is the optimization of the storage model. Compared to Filecoin and Arweave, Walrus introduces advanced erasure coding technology. This scheme maintains high reliability with 4-5 times data redundancy, and storage costs can be hundreds of times lower than Arweave. In other words, for the same data volume, Walrus can complete storage tasks with fewer nodes and lower costs. Files are sharded and distributed across nodes worldwide, ensuring resistance to censorship and enhancing fault tolerance.

**But that's not all.**

Walrus's core innovation is making stored data programmable. Through deep integration with the Sui chain, data stored on Walrus (Blob) can be transformed into programmable objects on the chain. Smart contracts can directly call, verify, and even manage this data, opening up new possibilities — dynamic, truly on-chain assets are thus born.

The most intuitive example is NFTs. Traditional NFT metadata often points to external storage or IPFS, risking link failures and content changes. Under the Walrus framework, the complete metadata of an NFT can be securely stored within, permanently bound to on-chain tokens, and thoroughly solve the old problem of asset-storage separation. This is undoubtedly a qualitative leap for the entire NFT ecosystem.

The concept of erasure coding has been around for a long time; the key is whether it can truly be implemented at scale or not. Another big hype in the Sui ecosystem? Let's see how long it can last before making any judgments. The claim of storage costs being a hundred times lower is a bit questionable—where does the data come from? Permanent binding of NFT metadata sounds good, but storing too much data on-chain will just blow up gas fees. Walrus can be used, but claiming to overthrow Arweave still needs some more time. This kind of programmable storage is indeed innovative, but I'm not sure how practical the applications will be.

As low as a hundred times the cost? That number sounds a bit exaggerated, seems a bit fishy. --- The Sui ecosystem is up to something again, but can Walrus beat Arweave? Feels a bit hollow. --- Programmable storage is indeed new, but its practical implementation still depends on the follow-up. --- The idea of binding NFT metadata to a chain is pretty good, much better than pointing to external links. --- Wait, Filecoin has already used erasure coding technology before, why is it being hyped as if Walrus invented it? --- To be honest, who still cares about decentralized storage? Not many are actually using it. --- Looks good, but projects like this are usually heavily hyped in the early stages, and practical implementation is difficult. --- Low cost by a hundred times? Did those previous projects just give up? --- Doing this on Sui is still somewhat interesting, it has natural advantages over other public chains. --- In plain language, it means data can run directly on the chain, making NFTs permanent. Got it.

Wait, erasing the technical cost of encoding can be a hundred times lower? That number really needs to be verified before I can believe it... Walrus's programmable storage sounds pretty good, but the key is whether the ecosystem can get off the ground, right? Another project aiming to revolutionize NFT metadata... Hopefully this time it’s not just PPT tokens again. Data ownership is indeed a pain point, but can Sui's gas fees really support large-scale applications? Arweave has been providing persistent storage for so many years, so what makes Walrus claim that the costs can be so much lower? Are there specific benchmark data? If this kind of programmable Blob approach really works, there might be some new opportunities in DeFi... but the prerequisite is to avoid a crash. Honestly, I’ve heard too many stories about decentralized storage; it all depends on whose token can finally survive.

NGL Walrus's idea is a bit extreme. Can erasure coding costs be reduced to a hundredth of Arweave's while still ensuring reliability? That's a bit too dreamy. Finally, someone is serious about building a storage layer. The IPFS approach should have been phased out long ago. Data programmability is indeed fresh, but what about the liquidity of the Sui ecosystem... Have you guys considered this? Anyway, another DePIN project. Let's wait and see the actual usage. Will Walrus also fall into the same NFT metadata trap? I don't quite understand erasure coding. Can someone briefly explain why it would be so much cheaper? Feels like another hype cycle. The key is still when the mainnet will truly go live.

A hundred times lower cost? That number sounds a bit suspicious; we’ll have to wait until it launches to believe it. --- Honestly, Walrus’s programmable storage is quite innovative, but the NFT case feels a bit overhyped. --- I get the optimization of erase coding, but the key is whether the ecosystem can really come alive. --- Another storage project, is this really different this time? --- Applications on Sui are becoming more competitive. It’s hard to say how much market share Walrus can really grab. --- It seems a bit clearer than Arweave’s logic, at least without so many historical baggage. --- Programmable Blob sounds amazing, but whether it will actually be practical is another story. --- Permanent binding of NFT metadata sounds good, but the real question is how many projects are willing to migrate. --- A hundred times cost difference? Is this compared to Arweave’s current price or to the theoretical cost? Need to clarify.

actually if you read the whitepaper the erasure coding math doesn't quite add up like they're claiming... 100x cheaper than arweave? nah, called this months ago when the tokenomics unlock schedule drops next quarter watch the dump pattern

Walrus's erasure coding is indeed awesome, and the cost being that low is a bit outrageous. --- I believe in the storage programmability on the Sui chain. NFT metadata binding can finally solve the problem of abandoned projects. --- Cheaper than Arweave by a hundred times? This data needs to be verified, or it might just be another overhyped project. --- Speaking of which, can storage sharding across global nodes truly be completely censorship-resistant? I have a feeling there are pitfalls. --- Permanent NFT binding sounds good, but who will bear the operational costs in the long run? --- Has anyone used Walrus? Or is it just another ideal technical solution?
