Onchain storage has two newcomers worth a closer look: @WalrusProtocol on Sui and @irys_xyz on its own L1 (Aptos' @shelbyserves to join soon). Walrus uses Sui for consensus and payments. Irys rebuilds everything so contracts can read blobs natively. Each design bets on a different bottleneck. 1. Plug-in versus standalone - Walrus plugs erasure-coded storage into Sui. Developers keep Move, RPCs, and Sui’s network effects. - Irys ships a new chain where storage, execution, and consensus share one validator set. Deep data integration, tougher bootstrap. 2. Token model - Walrus uses two tokens. $WAL covers storage; $SUI covers gas. Costs stay separate, but builders need to watch two markets. - Irys uses one token. $IRYS pays every fee and funds every reward. UX is simple, but price swings hit security and storage together. 3. Durability math - Walrus cuts files into shards and adds parity. Roughly 5 bytes on the network back every byte you store. - Irys keeps 10 full copies. Overhead is higher, but the proof system stays simple. 4. Permanence policy - Walrus rents space. Pay while you need the data; renew or it disappears. - Irys sells permanence. Pay once into an endowment and the network stores it forever (short term storage also supported). 5. Current traction - Walrus: ~1.1 PB stored, 100+ operators, notable brands like @pudgypenguins and @Claynosaurz already live. Clearly leading today. - Irys: ~280 TB stored, miner cohort still forming. Trump NFTs are already live, and Codatta’s robotics dataset soon. 6. Decision rule - Need quick launch inside the Sui ecosystem and tight cost control → Walrus. - Need contracts that stream large files and a pay-once, store-forever option → Irys. - Both models can coexist.
