[`RococoGenesisExt`](https://github.com/paritytech/polkadot-sdk/blob/a414ea7515c9cdc81f1d12410e646afc148250e8/polkadot/node/service/src/chain_spec.rs#L152-L171) is removed. It was the hack to allow overwriting `EpochDurationInBlocks`. Removal of `RococGenesisExt` prevents from manipulating the state to change the runtime constants. Changes: - Environment variable which controls the `time::EpochDurationInBlocks` value was added: `ROCOCO_EPOCH_DURATION` (epoch duration will be set to the value of env), - `10,100,600` versions of rococo-runtime are built in CI and put into `polkadot-debug` docker image. `rococo-runtime` building examples: - to build runtime for `versi_staging_testnet` which had EpochDurationInBlocks set to 100: ``` ROCOCO_EPOCH_DURATION=100 cargo build --features=fast-runtime -p rococo-runtime ``` - to build runtime for `wococo_development` ``` ROCOCO_EPOCH_DURATION=10 cargo build --features=fast-runtime -p rococo-runtime ``` - to build `versi-staging` chain spec: ``` ROCOCO_EPOCH_DURATION=100 cargo run -p polkadot --features=fast-runtime -- build-spec --chain versi-staging --raw ``` - to build `wococo-dev` chain spec: ``` ROCOCO_EPOCH_DURATION=10 cargo run -p polkadot --features=fast-runtime -- build-spec --chain wococo-dev --raw ``` It is also possible to change the epoch duration by replacing the `code` field in the chain spec with the hex dump of pre-built runtime wasm blob (because the epoch duration is hard-coded into wasm blob). --------- Co-authored-by: Bastian Köcher <git@kchr.de>

# Rococo: v2.1
|
|
|
|
Rococo is a testnet runtime with no stability guarantees.
|
|
|
|
## How to build `rococo` runtime
|
|
`EpochDurationInBlocks` parameter is configurable via `ROCOCO_EPOCH_DURATION` environment variable. To build wasm
|
|
runtime blob with customized epoch duration the following command shall be exectuted:
|
|
```bash
|
|
ROCOCO_EPOCH_DURATION=10 ./polkadot/scripts/build-only-wasm.sh rococo-runtime /path/to/output/directory/
|
|
```
|
|
|
|
## How to run `rococo-local`
|
|
|
|
The [Cumulus Tutorial](https://docs.substrate.io/tutorials/v3/cumulus/start-relay/) details building, starting, and
|
|
testing `rococo-local` and parachains connecting to it.
|
|
|
|
## How to register a parachain on the Rococo testnet
|
|
|
|
The [parachain registration process](https://docs.substrate.io/tutorials/v3/cumulus/rococo/) on the public Rococo
|
|
testnet is also outlined.
