Avail is a blockchain that is laser-focused on data availability: ordering and recording blockchain transactions, and making it possible to prove that block data is available without downloading the entire block. This allows it to scale in ways that monolithic blockchains cannot. Off-chain scaling solutions can unlock their full potential by offloading data availability to Avail. Standalone chains can bootstrap validator security by leveraging Avail for data availability.
Tanssi Network is an appchain infrastructure protocol backed by Polkadot's shared security framework. With Tanssi's ContainerChain technology, devs can deploy chains more efficiently and securely and have more time to grow their user base and enhance their application. When a project becomes a Tanssi ContainerChain, it gains access to a suite of tools and resources as services, including block production, data availability, cross-chain messaging, and bridges to external networks. Also included are management tools, templates, and key integrations such as wallets, indexers, RPC endpoints, block explorers and oracles.
