Download the runtime from IPFS:
https://ipfs.io/ipfs/QmUf6CDf7PxgpjqfHMTEiAj2LLrgpc3RKXNc8B2FxjC4Me?filename=kusama_runtime-v0818.compact.wasm

To check that the file you get from IPFS is legit, you can install substrate-runtime-hasherwith:
cargo install --git https://gitlab.com/chevdor/substrate-runtime-hasher.git

More infos here: https://gitlab.com/chevdor/substrate-runtime-hasher

Then run:

$ substrate-runtime-hasher kusama_runtime-v0818.compact.wasm 0x285fcc0b48bfcb48d01e25690dc7961fcce5730a5be77d9b732ac49415dde8d6

NOTE: Helping with seeding the runtime on IPFS would be nice: ipfs pin add QmUf6CDf7PxgpjqfHMTEiAj2LLrgpc3RKXNc8B2FxjC4Me

CI Release: https://github.com/paritytech/polkadot/releases/tag/v0.8.18

WARNING: The hash of the CI release will likely NOT match at first until srtool is integrated in the CI pipeline as well.
