Spent the last few months thinking about how thin the "decentralized" layer of normal web3 UX actually is. The chain is decentralized. The execution is decentralized. But the way almost every user sees the chain — block explorers, hosted RPC providers, some dashboard — is concentrated in maybe five vendors total. If one of them rotates an API key tier or IP-bans you, a meaningful chunk of "web3 tooling" stops working for you specifically, and nobody talks about it because it's the kind of dependency that's invisible until it breaks. The part I keep coming back to is the public RPC commons. Endpoints like publicnode, mempool dot space, blockstream, and Solana's mainnet-beta are open and unauthenticated, and they're genuinely good enough for read-side workflows — balances, tx lookups, gas estimation, mempool fees.…
