CORD v0.8.0 Release checklist

Release Checklist

This is the release checklist for CORD v0.8.0. All following checks should be completed before publishing a new release. The current release candidate can be checked out with git checkout release-v0.8.0

All Releases

These checks should be performed on the codebase prior to forking to a release-candidate branch.

Verify spec_version has been incremented since the last release. If the runtime was published (release or pre-release), either the spec_version or impl must be bumped.
Verify previously completed migrations are removed.
Verify pallet and extrinsic ordering has stayed the same. Bump transaction_version if not.
Verify benchmarks have been updated for any modified runtime logic.
Verify builds are done using the production profile

The following checks can be performed after we have forked off to the release-candidate branch or started an additional release-candidate branch (rc-2, rc-3, etc)

Verify new migrations complete successfully, and the runtime state is correctly updated.
Verify CORD SDK & API are up to date with the latest runtime changes.
Push runtime upgrade to Sprintnet and verify network stability.
Verify Docker images are published

RFE: Provide a mechanism to check all transactions on a given identifier

Usecase: Anyone using 'chain' should be able to query the chain to see all transactions on the identifier. This would enhance the trust factor by multiple factor.

Can be implemented through pallet storage, or through a rpc method.

Right now, the projects like subql which can aggregate all events on the chain build a query for such things, but still, that becomes a request served from an entity outside of the chain, and hence outside the purview of chain governance. This is key in 'verification' of any data.

pallet_asset: implement a restore() call

After #267 is implemented, there would be a need to restore the revoked asset / instance.

This may help in a 'suspension' of asset to see if the particular transfer query would come on the revoked asset.

Test should assert for ReferenceIdentifierNotFound being returned properly in all the possible calls.
If there are more than one function returning this error code, all of them should be validated either as one test case or as multiple test cases.

Acceptance Criteria

Implementation Details

Look at other test cases, and add a test case for the same.
Ex: In pallets/network-membership check method test_duplicate_member_request which validates error code MembershipAlreadyAcquired

Need help to create a ChainSpec file for deployment

Steps I followed

Create new accounts for every node

Generate Sr25519 keys

./target/release/cord key generate --scheme Sr25519 --password-interactive

Generate ED25519 keys from Sr25519 keys

./target/release/cord key inspect --password-interactive --scheme Ed25519 "<seed phrase of the Sr25519 key>"

Choosing sidney-cord-dhiway as the first and main node (sudo)

All Sr25519 SS58 keys

sidney-cord: 5EX237TZo8zbSxTa4ehDoNYgsCxS2o57NiJB7jfb1NNyfnJb
europe-cord: 5EHonjewVo5BdCXmuQvX5FKTziCTL6Po56LN8LJnKHj2GZxA
usa-cord: 5DP59Md5jM1FGzcLQV6EyJffW568KqR9s3gEwv7rkmiAu1rU

Ed25519 keys for Grandpa

sidney-cord: 5FaP17pFGGtbFrzwVz3z4L6iJawnrtWsgKGzjJxMtEdH3ZG7
europe-cord: 5Dq3ZQKMscCsS5MCxaMDzdYVAfikJejkrksQ3kJQL6u54XLr
usa-cord: 5Ep9R2CPbNZXiqiEe8xZqRqUcZj9fs5pG67Hm1YZE1PH74DM

NOTE: I have also written down all the account details like seed phrase, passwords in a separate doc

Create chain spec file

./target/release/cord build-spec --disable-default-bootnode --chain local > cordV2.json

Make the chain spec in Raw

./target/release/cord build-spec --chain=cordV2.json --raw --disable-default-bootnode > cordV2Raw.json

What else I did

I have open all inbound and outbound requests in EC2 machine.
Used the public ip and Node Id to connect with the Node running on EC2 - but no luck
Failed to Transpile this Chainspec into RawChainspec to further use to run nodes.

I'm currently able to simulate 3-4 node CORD network with predefined accounts on my local machine. I'm trying to use the accounts I have just created to run a 3 Node CORD chain on 3 EC2 on different regions.

comeup with a elaborate steps on recovery / best practise on handling lagging finality

In case of finality lagging (can happen when 1/3rd of validators are down), we need a set of instruction to handle the chain, and its continuity.

The validators would be having logs like below in that case..

2023-08-15 17:11:03 Backing off claiming new slot for block authorship: finality is lagging.    
2023-08-15 17:11:04 💤 Idle (23 peers), best: #151637 (0xee66…81e1), finalized #151158 (0x28a6…91f8), ⬇ 1.6kiB/s ⬆ 1.6kiB/s

Update the README file

https://github.com/dhiway/cord/tree/develop/extras#generate-node-key

We must add an updated version of this information to the main readme file. The directory is outdated. Looks safe to remove.

[C4GT] Chain-Space: Add tests for `TypeCapacityOverflow`

Description

Subtask under : cord-network/community#7

New testcase can be tested under cargo test -p pallet-chain-space after adding it in the code.

Goals

Add tests for TypeCapacityOverflow for pallet/chain-space

Expected Outcome

Test should assert for TypeCapacityOverflow being returned properly in all the possible calls.
If there are more than one function returning this error code, all of them should be validated either as one test case or as multiple test cases.

Acceptance Criteria

Implementation Details

Look at other test cases, and add a test case for the same.
Ex: creating_a_duplicate_space_should_fail which validates error code SpaceAlreadyAnchored

Replace mentions of the `ci-linux:production` image tag with the `ci-unified:latest`

Hello everyone!

I see that your project uses one of the paritytech CI images. Just FYI, the paritytech/ci-linux:production image has been deprecated in favor of the paritytech/ci-unified image. Please use the paritytech/ci-unified:latest image in your workflows, pipelines or docs, or use the specific tag (e.g. paritytech/ci-unified:bullseye-1.70.0) for granularity and versioning, but you will still need to check upstream for new releases.

Switch to using distroless in Dockerfiles

We currently use a full blown ubuntu:20.04 for Cord release images. While useful for debugging, an Ubuntu image contains packages that are not required to run a Cord node.
Using a fat Docker image:

increases the network bandwidth as larger image needs to be pulled. It is especially important in orchestrated environments when pulls happen often
widens the attack surface due to a larger number of dependencies in a resulting image
decreases noise/signal ratio of security scanners as it should scan through more packages

[C4GT] Chain-Space: Add tests for `SpaceDelegatesLimitExceeded`

Description

Subtask under : cord-network/community#7

New testcase can be tested under cargo test -p pallet-chain-space after adding it in the code.

Goals

Add tests for SpaceDelegatesLimitExceeded for pallet/chain-space

Expected Outcome

Test should assert for SpaceDelegatesLimitExceeded being returned properly in all the possible calls.
If there are more than one function returning this error code, all of them should be validated either as one test case or as multiple test cases.

Acceptance Criteria

[C4GT] - Integrate with Sunbird RC

Project Details

Like Bitcoin, Ethereum, and Polkadot, CORD refers at once to a network protocol and the
primary federated public network that runs this protocol. CORD is a free and open project, with
the code being placed under a FLOSS license. The project is developed in an open manner
and accepts contributions where ever they are helpful.
The implementation of the CORD Layer-1 Framework (CLF), known as CORD and includes a full
protocol implementation together with API bindings and SDK. CORD is designed to be a
general-purpose blockchain technology stack, neither uniquely for a federated network nor
public/private network operation. This paper nonetheless describes CORD under the context
of a federated network.

More on the project @ https://cord.network

Features to be implemented

Integrate ability to anchor schemas through APIs
Integrate ability to create 'registry' on chain
Integrate APIs to create credentials, or entries on to this registry

What exists

CORD Blockchain
API interfaces, API service code (issuer-agent)
An attempt done earlier on the similar lines, but need a revisit now, with new API set and DID based logic
- Sunbird-RC/sunbird-rc-core#152 by @gamemaker1

What needs to be built

Sunbird RC project should get a support for anchoring the credentials, and registry entries on to CORD Blockchain for immutability.

Complexity

Medium

Skills Required

Typescript, REST APIs, basic understanding of Sunbird RC, Rust
