Hey everyone,
We’ve been keeping busy refining features, boosting performance, and rolling out improvements to make everything run smoother. There’s always something new to tackle. Here’s what we’ve been up to lately!
Weeks 6-7 (February 3 - February 16, 2025)
Dincho Todorov
We added new configuration options to allow initializing a HyperChain validator directly from the node config file. Additionally, we worked on improving node configuration defaults and validation.

We fixed an issue with the /transfers endpoint where the ref_tx_type and ref_block_hash fields were swapped. Another fix addressed a bug causing MDW to crash when checking if a HyperChain is connected to its parent, as seen in this update.
To improve performance, we added transaction fees to the MDW table, preventing repeated fetching and resolving timeout issues on the stats endpoint. We also explored modifying MDW config paths in Docker to mirror those in the node image, making MDW a drop-in replacement.
Additionally, we updated ae_plugin to remove the requirement for the node path to contain rel/aeternity and pinned it in MDW to avoid breaking earlier versions. We made MDW ignore query parameters starting with an underscore and improved Swagger documentation by adding an enum for transaction types and specific types.
Ongoing efforts include modifying the top miners’ endpoint to return data for the actual last 24 hours instead of breaking it down by day, adjusting /stats/transactions/total endpoint parameters to use timestamps, and increasing the record limit on MDW stats endpoints from 100 to 1000. We are also working on adding the accounts count to the total and delta stats endpoints.

We set the target to the height of the end-of-epoch block, validated the contract call in the end-of-epoch call, and started adding tests for following the fork chosen by vote. More details can be found in this PR.
Additionally, we integrated code into the new hole production framework and added tests for targets, the EOE block flag, and the end-of-epoch cal.

We realized that the HyperChain implementation doesn’t fully handle parent chain finality, so we started sketching a solution to address this issue.
Additionally, we’ve been working on hole production, ensuring that when a block producer is absent, the next one can create an empty block to maintain continuity. Fork resolution has also been a long-term focus, and after struggling with a complex design, we successfully simplified it, leading to a major merge at the end of the week.
Thomas Arts
We participated in meetings and discussions.

We focused on bringing the tests for the holes-and-forks branch to working condition. Multiple test groups and suites were reviewed, investigated, and fixed to align with the new consensus code. Updates included fixing hc_SUITE and splitting its second half into hc_epochs_SUITE, repairing hc_pinning_SUITE so that it now passes, and relocating aehttp_hyperchains_btc_doge_SUITE to hc_btc_doge_SUITE with API call fixes.
Further work involved updating the branch from master to integrate recent changes and resolve any arising conflicts. Final touches were applied to hc_SUITE to ensure full functionality, while hc_epochs_SUITE remains under investigation due to continued voting for shorter epochs despite expectations for a longer epoch transition.
Richard Carlsson
Did another dive into the time API to explore ways to speed up time-dependent tests, including investigating the addition of a time virtualization layer.
We also worked on splitting and rebasing current branches, reviewed the new holes-and-forks branch, and explored unifying hole candidate and key candidate modules. Additionally, we reviewed and fixed the HyperChains whitepaper and revisited the logdir-config branch.
Måns af Klercker
We continued work on pinning validation but had to pause due to required fixes and implementations around finality on the parent chain. Additionally, we produced a video on running Docker and added validator configuration workflows based on the core HyperChain documentation. Work on penalties was also restarted to refine the system further.
Thank you for your support! As always, feedback from the community and your comments are greatly appreciated!
