8 Best Sia Alternatives & Competitors (2026)

The Ethereum Foundation funds core protocol development and research for the Ethereum blockchain. It focuses on scalability, security, and developer tooling for smart contracts and decentralized applications. Unlike Protocol Labs' broad multi-domain network model, the Foundation concentrates resources on a single public chain and its ecosystem upgrades. Pricing is grant-based with no direct product fees. Teams building dApps or layer-2 solutions often compare it to Protocol Labs when seeking protocol-level funding versus infrastructure research across storage and data layers.

Arweave offers permanent, one-time payment decentralized storage using its blockweave architecture. It targets data permanence for NFTs, archives, and web content. Compared with Protocol Labs' Filecoin, Arweave emphasizes simpler pricing and stronger immutability guarantees but lacks the broader startup network and multi-technology research scope. It appeals to users needing long-term storage without ongoing fees or complex retrieval markets.

The Web3 Foundation supports the Polkadot ecosystem through grants and research focused on interoperability and multi-chain infrastructure. It shares Protocol Labs' interest in decentralized protocols but centers funding and governance around the Polkadot relay chain rather than a wide-ranging innovation network spanning AI and hardware.

Storj provides decentralized cloud object storage with end-to-end encryption and S3 compatibility. It competes with Filecoin on enterprise-friendly storage use cases while offering more traditional billing. Storj does not maintain an equivalent open research network or protocol suite like IPFS and libp2p, making it narrower in scope than Protocol Labs.

ConsenSys builds and invests in Ethereum tooling, infrastructure, and enterprise solutions including MetaMask and Infura. It operates as a commercial company with product revenue, contrasting Protocol Labs' non-profit-style network approach. Organizations compare the two when choosing between venture-backed product suites and open research networks.

Swarm delivers decentralized storage and communication primitives integrated with Ethereum. It targets data availability for dApps and focuses on incentives within the Ethereum stack, providing a narrower alternative to the multi-protocol, multi-field scope of Protocol Labs.

The Algorand Foundation funds ecosystem growth, grants, and research for the Algorand blockchain emphasizing pure proof-of-stake and carbon-negative operation. It differs from Protocol Labs by concentrating on one layer-1 chain rather than operating an expansive innovation network across storage, data, and emerging tech.
