Caldera solves this. Rollups + Metalayer == internet of rollups. The thesis is not new. Cosmos and Polkadot fell short because they solved interop before they solved app chains. We did the opposite and have 100+ thriving chains with 700M+ TVL that we now are working to connect!.
The obvious end state of blockchains is app chains. Every successful app will have its own chain. UX is the only thing stopping it now. Wallet and bridging infra will get there soon enough.

Caldera is building an interconnected internet of blockchains. Today, we already power 30+ mainnets, securing $700M+ in TVL. Our mission is to infinitely scale Ethereum — unlocking a faster, cheaper, and more powerful decentralized web.

Kinto just became a Stage 1 rollup per @l2beat — a huge milestone for compliant, modular L2s. It also becomes the first @arbitrum orbit chain . We’re proud to have supported @KintoXYZ from day one. Here’s how we helped 👇.
What a journey. @KintoXYZ is the 5th chain to become stage1* and the first appchain to get this stage. Incredible work together with @l2beat to understand what the stages framework meant for a world where kinto exists, you can learn about the journey and the all the details

Caldera has 10M+ active wallets on mainnet, each paying real money to our sequencers for blockspace. If that's not traction, then I don't know what is.

The best L2s are enormously profitable. Caldera rollups have made millions in profit. Rollups who create valuable blockspace for users have earned it. Pay Ethereum for security rather than shipping value to validators via token inflation.

Solana wants to build an on-chain NASDAQ and they believe in a future where a single fast chain will host most of the world’s financial activity. It’s a plausible vision but I think it won’t be correct. I believe in Ethereum, rollups, and of course @Calderaxyz. Quick thoughts on.
What if:. - Institutions want their own L2s that plug into the most secure L1?. - Decentralization matters for high value tokenized assets?. - The chain without downtime actually has the most upside?. Will the asset securing the world ledger be worth less than $1 trillion?. $ETH.

Does crypto need more infra?. Yes, but not across the board anymore. We’re past the “We need to scale at all costs” phase. Scaling is largely solved for now: rollups have unlocked enough blockspace to meet current and near-term demand. The real challenges today are around

Purpose-built L1s are pure VC, insider valuation play — and most are going to zero over the next 2 years. We've considered building tooling to help developers launch purpose built L1s. In February 2022, the very first demo we built as a company was a tool to launch Evmos fork.

L2’s give teams ability to define their own tradeoffs:. A general purpose defi L2 should aim for stage 2 and maximal censorship resistance. A tradfi L2 should be compliant with its jurisdiction. Magic happens when intermediaries connect the two.
Some gems from @RaoulGMI’s clip:. “I think the entire financial system builds on ETH”. “You don’t get fired for building on ETH”. “[Other L1s don’t have] the Lindy effects ETH has”. “The banks love an L2 — they have control over certain things but still have settlement on L1”.

My advice on how to get started in crypto: try to make as much money as you can and build a Twitter presence. Crypto is all about culture and money, and you’ll learn more by engaging in competitive markets with fairly objective measures of value than trying a passive approach.

Some miscellaneous thoughts and opinions on based and native rollups after spending my Sunday afternoon digging in. - The vibe I get is that the motivation for creating based rollups is to propose an architecture where a higher slice of value created by the rollup accrues to.
I realized that I had no idea what the heck based or native rollups were really about. So I used Deep Research to help me understand what a based and native rollup is and the tradeoffs, both technical and nontechnical (see article). Here's this breakdown, hope this is helpful!.

Consensus take: L2 interop is broken today. Narrative violation: the solution is simple and does not need any fancy new protocols or infra. The simple solution: a major L2 infra team needs to vertically integrate their existing stack from the protocol to UX layer, and enable

Using storage proofs in cross-chain interop is super cool because it allows any rollup to trustlessly verify state on any other rollup, as long as they both settle on Ethereum. Here's a quick breakdown of how storage proofs might work in an intents-based bridge:. - Say a user.

Why has Caldera succeeded in building an "Internet of Blockchains" where Polkadot and Cosmos failed?. There were three main problems with building an app-chain via Polkadot or Cosmos:. High operating cost - paying for validators via token emissions was unsustainable because there.
