neutron-rehearsal-1 Chain Details

The neutron-rehearsal-1 chain will be launched as a Neutron persistent chain to test Interchain Security functionality.

  • Chain-ID: neutron-rehearsal-1

  • denom: untrn

  • minimum-gas-prices: 0untrn

  • timeout_commit: 2s

  • Spawn time: 2023-04-11T18:30:00Z

  • GitHub repo: neutron-org/neutron

  • Release: v0.4.0

  • Genesis file with CCV state: neutron-rehearsal-1-genesis.json

  • Reference binary: neutrond-linux-amd64

  • Binary sha256sum: 394736d71f5798d0de3427aac96fba27f8df07c23d8d47eedd837774f4e4cb48

  • Genesis file without CCV state: neutron-rehearsal-1-genesis-without-ccv.json, verify with shasum -a 256 neutron-rehearsal-1-genesis-without-ccv.json

  • SHA256 for genesis file without CCV state: e5a5e9f8ba69a846d18737c2d2a6a6de0250f45c53c07df274dc80ab9bda2ba0

  • Genesis file hash

    • The SHA256 is used to verify against the genesis file (without CCV state) that the proposer has made available for review.
    • The neutron-rehearsal-1-genesis-without-ccv.json file cannot be used to run the chain: it must be updated with the CCV (Cross Chain Validation) state after the spawn time is reached.
    • The genesis file includes funds for a relayer and a faucet account as well as account with funds for different internal needs, signed_blocks_window has been set to 864000, and min_signed_per_window has been set to 5%.

  • Binary hash

    • The neutrond-linux-amd64 binary is only provided to verify the SHA256. It was built with Interchain Security release v0.4.0. You can generate the binary following the build instructions in that repo or using one of the scripts provided here.

  • Spawn time

    • Even if a proposal passes, the CCV state will not be available from the provider chain until after the spawn time is reached.

If you want to build genesis by your own please take into account difference between the ccvconsumer section generated by version v9.0.2 of gaiad and the ccvconsumer section required for neutron to run. Please check and add "soft_opt_out_threshold": "0.05" to the params section if it absent.

For more information regarding the consumer chain creation process, see CCV: Overview and Basic Concepts.
