Main net is running RNode version 0.12.8 ( https://github.com/rchain/rchain/releases/tag/v0.12.8). This version resolves a bug around hashing of the blocks. The code will choose between the previous hashing scheme or the new hashing scheme based on the version of the node.
Testnet 0.13.0 had been running Since about March the 10th. All block merge code is now on the testnet, but finalization needs to be worked on and that is the current focus of the team. Current version on this LLBM test net is 0.13.0-alpha3. This version enables testing the sharding related behavior. Dappy (fabcoTech) and other community members are currently testing this version.
There were two planned hard forks: Hard Fork 2 for block merge (release versioning will be 0.13.x) and Hard Fork 3 for PoS changes (release versioning will be either 0.14.x or 1.x.x) to eventually enable a fully decentralized node with external validators. Most of the Hard fork 3 changes are now likely to be included in Hard Fork 2. We will do a Hard Fork 3 only if needed.
Main Focus is to prepare the leaderless block merge Hard fork (hf2), specifically (a) complete the finalization feature for multi-parent block merge for release to Test net (b) a lot of testing + bug fixing and (c) performance improvements (d) Completed - Adding shardId inside the signatures, to enable multi-shard operation and prevent reusing of deploys from one shard in another shard (e) sdk project to make the code more modular and serve as a base for RNode domain logic with corresponding data types (f) Prepare for trusted external validators in order to decentralize the network.
Other work includes resolving any identified bugs, hardening the network and working with external customers.
Significant progress on finalization and Block merge (LLBM). We expect 0.13.alpha4 release on the test net later this week that includes block merge and finalization with simple protocol (i.e. potential network partitioning ignored). Both Tomislav and Nutzipper are working on this. The remaining work after this release is handling invalid blocks, implementing slashing and thorough testing. Stas, Max and others will be helping with tests to support this effort. Stas had recently been working on the mockito for scala testing framework.
Will is preparing his PR for bonding of external validators for review by the team. https://github.com/rchain/rchain/issues/3714 . He needs to make some minor cleanup adjustments to the PR. This will be used as a test case to test the registry update process. After this, he will be working to implement dckc's request for a separate REV address for rewards to validators. There will be a requirements clarification session tomorrow. Design and other activity will follow that.
Denis is temporarily switching to support parsing of a small EDI extension language for an external customer. He will be supporting the testing effort for LLBM, as well as the error reporting and error handling framework along with Nutzipper.
External validator engagement as well as customer/market engagement continues.
Development Plans for the rest of the year and beyond - for reference
Near term plans and releases are as below:
Block merge release hard fork 2 plus any configuration changes that do not need extensive work - Leaderful and Leaderless block merge. All PoS contract changes initially intended for hard fork 3 are also included in this release, including enabling future updates to be least disruptive. (in progress)
External validators (only with trusted community validators and third parties, aka Friends & Family) on the test net (in progress)
Friends & Family + trusted third parties validation on the main net
Potentially one or more releases for Configuration changes and/or performance improvements,
External validators among extended ecosystem (e.g. exchanges, if they're willing)
External validators in the wild
Hard Fork 3 is only if absolutely required (see note 1). We currently do not anticipate a need for this.
Feature releases driven by external market engagement
Reminder: It's important for all Wallet makers to update their code to match the new implementation where minimum phlo price is a parameter. Please communicate this to any wallets you are using. Wallets will have to call /api/status to get min phlo price accepted by the validator and put that value in deploy data instead of the currently used constant 1.Tomislav has updated the wiki at https://github.com/rchain/rchain/wiki/Cost-accounting-in-RChain#phlopriceWe will start communications with exchanges also for HF2.
Explanation of the different Hard Forks (for reference)
Proceeding further with block merge requires changes to the per validator vault to make it a per deploy vault/purse etc. We are currently finalizing the design for this. Actual code and test will take some time. We are potentially looking at this scenario: 1. First hard fork for balances and removing the slashed validator 2. Second hard fork for block merge - This is the fastest way to get block merge on the main net without holding it until the third hard fork. This includes REV balance merging (aka per deploy vault), attestation messages and the Tree depth being increased to four. 3. Third hard fork with all other changes. Third hard fork includes implementation of a lot of changes including the PoS contract changes, Soft fork process etc. Design for soft fork process is complete and is being reviewed by the team.
(Hard Fork) TEST NET 2 ADVISORY: (for reference)
To test the version of block merge with data changes that need a hard fork, we are creating a separate feature branch and a TEST NET 2 as the testbed for this feature branch. This content will be left here until we are close to Hard Fork 2 implementation on the main net. TestNet 2 is now available for the community to test their contracts on.
There will be no guarantees of data storage format compatibility on Test Net 2, as the data storage format changes are incrementally implemented. The anticipated changes are mostly storage level format changes visible only to node operators. We encourage the community to start using Test Net 2 in addition to the current test net, so that we can quickly identify and resolve any issues with the upcoming hard forks. All new development should be targeted to TEST NET 2 and all current code MUST BE tested against TEST NET 2 to ensure future compatibility.
On all the hard forks on the main net, we will be starting from an empty state, with REV balances only. On Test Net 2, this 'loosing the state' will be repeated multiple times.
