Runtime Hash

blake2b 256bit WASM Runtime hash can be computed with b2sum command:

$ b2sum -l 256 joystream_runtime_6_15_0.wasm
cae786ae24e5d625acd063625603b8c0e064ec78761e6280ec0eede588c8d521  joystream_runtime_6_15_0.wasm

The runtime file was produced on docker hub built from the release commit. check the build logs here The computation appears near the end of the log.

Proposal on testnet

Verifying the build matches the proposed runtime

Instructions to build and verify that the runtime was built from the current release commit (you need docker tools):

# get the same rust build environment
docker pull joystream/rust-builder
# clone the joystream repo
git clone https://github.com/Joystream/joystream.git
cd joystream
# checkout the release version 
git checkout v6.15.0
# build the node and runtime
./scripts/build-joystream-node-docker-image.sh
# Get some coffee and check the computed hash at the end of the build :)

Constantinople runtime new features:

• New proposal system that strengthens the governance structure of the platform
• Adjusted inflation curve to better reflect a new realistic economic system for the platform

New Features

• Forum
• Improved Storage and Discovery Module

Bug Fixes

• Clearing role entry requests correctly after expiry
• Fix implementation of removing actors by sudo

Build Details

compiled wasm blob hash: f430d43887a5c71692bbd2a063d00ad699f00565ad069f965023fb2e135983e9

Steps to reproduce build:

git clone https://github.com/Joystream/substrate-runtime-joystream
git checkout v5.4.0
./build-with-docker.sh

will generate a joystream_runtime.wasm file that should match the attached joystream_runtime_v5.4.0.wasm in this release.

To verify the attached blob download it and run:
OSX:

brew install b2sum
b2sum -a blake2b -l 256 joystream_runtime.wasm

Ubuntu 17.0+:

apt-get install coreutils;
b2sum -l 256 joystream_runtime.wasm
