App-Chains and Rollup-as-a-Service
How Cosmos-style app-chains and modern Rollup-as-a-Service (RaaS) providers (Caldera, Conduit, AltLayer, Gelato) let applications deploy dedicated chains, and the trade-offs vs shared chains.
The App-Chain Thesis
The app-chain thesis argues high-value applications should run on their own chain rather than sharing block space with other apps. Benefits: customised consensus parameters, sovereign tokenomics, no congestion from unrelated apps, full control over upgrades. This is Cosmos's approach — many sovereign chains interoperating via IBC. Modern rollup-as-a-service (RaaS) has brought a similar model to Ethereum — anyone can deploy a dedicated rollup for their application, benefiting from Ethereum security while having full control over their chain's parameters.
Why RaaS Emerged
Deploying and operating a rollup from scratch is expensive and complex — requires deep infrastructure knowledge, ongoing security work, monitoring systems. RaaS providers (Caldera, Conduit, AltLayer, Gelato, others) offer 'rollup as a service' — spin up a dedicated rollup with a few clicks. They handle sequencer operation, upgrades, monitoring, and infrastructure. Applications pay recurring fees for the service. This dramatically lowers the barrier to launching a dedicated chain — many applications now can deploy app-chains that couldn't before.
Major RaaS Providers
**Caldera**: OP Stack chains as a service; multiple production deployments. **Conduit**: OP Stack chains focused on gaming and consumer applications. **AltLayer**: Multi-stack support with restaking security via EigenLayer. **Gelato**: Multi-chain deployment across various stacks. **Alchemy Rollups**: Alchemy's rollup service. Each has different specialisations and technical approaches. The competition is real; multiple major applications have deployed rollups through various providers.
- App-chain thesis: high-value apps run own chains
