What Is Walrus (WAL)? Decentralized Storage Token on Sui

Walrus (WAL) is the token of a decentralized storage network built on the Sui blockchain, where 94 storage nodes held all 1,000 of its data shards in mid-October 2026. It topped CoinMarketCap's most-searched list that month, in the days after the Sui Foundation named Walrus the default storage layer for DATA Network's apps.

Most of those shards sit with a minority of the nodes. The 15 largest nodes hold 341 shards between them, more than the 333 faulty shards Walrus's design is built to tolerate, and 40 nodes reach two thirds of the total. Holders have staked about 1 billion WAL behind the network's storage nodes, which works out to 38.3% of the circulating supply.

What Is Walrus (WAL)?

Walrus stores large files, which its developers call blobs, on a network of independent storage nodes. It keeps the records and payments for those files on the Sui Layer 1 blockchain, where each stored file is an object that a Sui smart contract can own and renew.

It's the second major protocol from Mysten Labs, the Sui developer run by chief executive Evan Cheng. Walrus went live on mainnet in March 2025 with more than 100 independent node operators, and the Walrus Foundation raised $140 million that month in a private token sale led by Standard Crypto.

WAL is the Walrus protocol's own token, and storage buyers pay with it while holders stake it behind the nodes.

In early October 2026 the Walrus Foundation launched Walrus Console, a managed service that stores files and AI-agent memory and connects them to apps through an API key or MCP. Console users need no wallet or tokens, since the service handles and renews the storage for them.

Why Is Walrus Trending in October 2026?

In mid-October 2026 the Sui Foundation announced that DATA Network and its Trace registry for AI training data are joining the Sui stack. The foundation is investing $30 million in DATA Network, and the post says that "Walrus becomes the default storage layer for DATA Foundation applications."

DATA Network's own chain will be retired and its DATA token carried over one-to-one onto Sui. The post sets no date for that move and says a detailed timeline and holder transition plan will come out before the upgrade.

By CoinMarketCap's daily closes, WAL fell 8.40% on the day of the post. It rose 9.62% the next day to its mid-October close of $0.0384, while Phemex's FIL perpetual gained 5.74% and its SUI perpetual 1.87% on that same day.

How Does Walrus Work?

Walrus splits each file with RedStuff, a two-dimensional erasure code, and spreads the encoded pieces across 1,000 shards held by the storage nodes. The encoding stores about 4.5 times the original file size, according to Walrus's RedStuff parameters page, which is far less than a full copy on every node would take.

That overhead pays for resilience. The design budgets for up to 333 faulty or malicious shards out of 1,000, and Walrus says stored data stays available even if up to two-thirds of its nodes go offline.

Users buy storage in epochs of two weeks on mainnet, and a buyer can pay up to 53 epochs ahead, or about two years. Walrus prices that storage in US dollars and charges for it in WAL, adjusting the WAL amount so the dollar price holds steady.

Walrus goes after the same customers as Filecoin's decentralized cloud storage, and its pitch is programmability. Every file gets a cryptographic fingerprint recorded on Sui, so an app, an auditor or an AI agent can check that the file is still there and unchanged.

Who Runs Walrus Storage?

Walrus picks a committee of storage nodes for each epoch, and shards go to nodes roughly in proportion to the WAL staked with them. In the epoch that began in early October 2026, 94 of the 137 registered nodes made the committee. The two largest hold 26 shards each and the smallest holds 2.

Line the nodes up from largest to smallest and the running total passes 333 shards at the 15th node, which brings it to 341. It takes 40 nodes to reach two thirds of the shards, and the remaining 54 nodes share the last third. Two nodes registered under the Mysten Labs name hold 51 shards between them, and they rank among the four largest.

Method: the shard counts come from the committee field of Walrus's staking object on Sui for that epoch, sorted from the largest node to the smallest and added up. The counts sum to exactly 1,000, and the 333 limit is the figure Walrus's own docs give for a 1,000-shard network.

The census measures how few nodes it takes to reach the fault budget, and it makes no claim about any operator's intent. It moves every two weeks with the committee, so it's a number any holder can recheck.

Walrus Tokenomics

WAL's supply is fixed at 5 billion, all minted in one Sui transaction in February 2025. Its treasury has two public functions, one reporting supply and one burning tokens. Neither can create WAL, so the token has no mint path. A transaction the next day made the package immutable, so no one can upgrade the code to add one. The coin also has no freeze or deny-list authority.

Tokens outside circulation reach the market through a monthly release schedule that runs to 2033, and our guide to crypto vesting and cliffs explains how schedules like it work.

How Walrus Staking Works

Walrus staking runs on delegated proof of stake. You delegate WAL to a storage node, and the node's total stake decides how many shards it holds and how much in storage fees it earns for its stakers.

Timing matters here. Walrus picks each epoch's committee at the midpoint of the epoch before it, so stake you add after that point starts counting one epoch later, and withdrawals follow the same clock.

Walrus never slashes the principal you delegate, according to its WAL tokenomics FAQ, and slashing a misbehaving node burns its operator's commission. Fees flow into a storage fund that pays nodes and stakers at the end of each epoch, and the system burns 3% of each epoch's total rewards before paying them out.

How to Buy Walrus on Sui Safely

Phemex does not list WAL, and its WAL spot pair and perpetual are both delisted. WAL trades in decentralized pools on Sui, so the safe route runs through your own Sui wallet and the exact coin type in the table below.

1. Set up a self-custody Sui wallet and fund it with a small amount of SUI, which pays the gas on every Sui transaction.

2. Copy WAL's coin type from the table and match its package against Walrus's Available Networks page.

3. Open a Sui decentralized exchange and paste that coin type into the swap, because other tokens borrow the Walrus name, among them Walrus the Tusk (TUSK) and Winter Walrus Staked WAL.

4. Check that the token shows the symbol WAL with 9 decimals, then send a small test swap first.

5. Confirm the WAL lands in your wallet under the same coin type before you swap a larger amount or stake it.

What Are the Risks of Walrus?

• DATA Network's move has no date. The Sui Foundation's post sets no timeline for retiring DATA Network's chain and promises one before the upgrade. Until that upgrade ships, Walrus as DATA's default storage layer is a plan on paper.

• Fifteen nodes hold more than the fault budget. Walrus's safety math assumes no more than 333 of its 1,000 shards fail at once, and its 15 largest nodes together hold more than that. Shards follow stake, so the spread can widen or narrow at each two-week committee change.

• New supply arrives every month. More WAL enters circulation each month until 2033 under the release schedule. Holders carry that supply growth even in a month when paid storage on Walrus falls.

• Lookalike tokens on Sui. Several tokens use the Walrus name, so a swap made by name alone can buy the wrong coin. Only the full coin type identifies WAL.

Is Walrus a Good Investment?

Walrus is a high-risk bet that paid demand for its storage keeps growing. The data from mid-October 2026 shows a working network with about 1 billion WAL staked and an announced storage client in DATA Network, alongside a fault budget that rests on 15 nodes.

What would strengthen the case is a dated DATA Network migration and a wider spread of shards across the committee, and a holder can track both every two weeks.

Frequently Asked Questions

What is WAL crypto?

WAL is the token of Walrus, a decentralized storage network on Sui. Buyers pay for storage in WAL and holders stake it behind storage nodes. Its supply is fixed at 5 billion tokens, all minted in February 2025.

Is Walrus crypto a good investment?

It's a high-risk token tied to demand for Walrus storage. In mid-October 2026 its 15 biggest storage nodes held just over a third of the network's shards, and DATA Network's move onto Walrus had no set date.

Can you buy WAL on Phemex?

Phemex has delisted its WAL spot pair and its WAL perpetual, so it does not list WAL. You can swap SUI for WAL on a Sui decentralized exchange after matching WAL's full coin type.

How does Walrus staking work?

You delegate WAL to a storage node, and nodes with more stake get more of Walrus's 1,000 shards and more of its storage fees. Stakers share those fees, and Walrus never slashes the principal they delegate.

Who created Walrus?

Mysten Labs developed Walrus as its second major protocol after Sui, and Walrus mainnet went live in March 2025. The Walrus Foundation promotes the protocol and raised $140 million in a private token sale that month.

Bottom Line

Walrus is designed to stay safe with up to a third of its shards faulty, and in mid-October 2026 its 15 biggest nodes held just past that line. DATA Network would bring more data onto that same committee, so the spread of shards is the figure that decides how much margin the design really has.
