Between August 25 and October 6, 2026, ten of 110 chains we scanned stopped producing blocks for 10 minutes or more. TAC was down 10.6 days, Neutron 77.75 hours, Cosmos Hub 24.8 hours, Cronos 17 hours. The full list, the method, and the raw data.
Read →Kava runs an EVM beside a Cosmos SDK chain. Measured: 5.7 s blocks, instant finality, a 10,000-block getLogs cap, ~100 blocks of state, archive routing.
Read →How to use Cronos EVM over JSON-RPC — chain ID 25, ~0.42 second blocks with instant finality, a 10,000-block eth_getLogs cap, historical state pruned after ~100 blocks, and no debug or trace namespace.
Read →How to query Babylon Genesis over RPC and LCD — CometBFT 0.38.22 on chain bbn-1, ~9.6 second blocks, 68 validators, blocks filled with finality signatures, why tx_search refuses ranges, and the pruning floor that gave three different answers in six calls.
Read →How to query Neutron over JSON-RPC — CometBFT 0.38 on chain neutron-1, why there is no numeric chain ID, the header fields that disappeared in 0.38, a tx_search that times out instead of answering, a pruning floor that differs between nodes, and a block time that measured 7s this week against a 2s baseline.
Read →Injective is a Cosmos-SDK finance L1 (injective-1) whose defining feature is a native, chain-level central-limit order book — a protocol module, not a smart contract. The RPC is CometBFT/Tendermint JSON-RPC (not eth_*), with sub-second blocks and instant single-block finality. Here's the developer map, including how you query the exchange module and place orders.
Read →On Ethereum, 'the RPC' is one JSON-RPC endpoint. On Cosmos chains, 'RPC' can mean three different interfaces — Tendermint/CometBFT RPC, REST (LCD), and gRPC — each on its own port, each for a different job. Here's what each one does, when to use it, and the mental shift from calling contracts to querying modules.
Read →Osmosis is the leading Cosmos DEX — a non-EVM Cosmos SDK chain (osmosis-1) on CometBFT. The twist for developers: the AMM isn't a smart contract you eth_call, it's a native chain module you query over Tendermint RPC, REST, or gRPC. Here's how to read pools, prices, and swaps.
