Technical Activity Report

January 2026

January 2026 centered on open-sourcing the Roborovski v2 codebase, migrated from the private robo2-temp workspace to a new public repository under the AGPL-3.0 license. Alongside this milestone, development continued across Roborovski’s action streaming system, ABI decoding infrastructure, and API surface. Unicove integrated sentiment voting into its dev branch and began consuming the Roborovski v2 API with a v1 fallback mechanism.

Key Achievements:

  • Open-sourced Roborovski v2 codebase from private robo2-temp to public greymass/roborovski under AGPL-3.0
  • Hardened the action streaming system with keepalive, panic recovery, and compaction concurrency
  • Integrated sentiment voting (accounts + multisig proposals) and search plugin refactor into Unicove dev branch
  • Began Unicove integration with Roborovski v2 API including v1 fallback and new transfers page
  • Advanced wharfkit/roborovski TypeScript client from rc2 to rc5 with new activity() and transaction() methods
  • Fixed ABI decoding edge cases in go-eosio underpinning Roborovski’s abicache

Technical Significance: The open-sourcing of Roborovski makes the v2 blockchain history infrastructure available to the broader Antelope ecosystem. While still in release candidate phase with data inconsistencies being resolved, the public repository enables external review and contribution. The coordinated work across greymass/roborovski, wharfkit/roborovski, greymass/go-eosio, and greymass/unicove demonstrates a full-stack progression from Go indexing services through TypeScript client library to end-user application integration.

Roborovski v2 Full-Stack Integration

Repositories: greymass/roborovski, wharfkit/roborovski, greymass/go-eosio, greymass/unicove, greymass/statindex-ui-prototype

Previous Context: See December 2025 for robo2-temp and wharfkit/roborovski rc1-rc2 development.

January brought Roborovski v2 development out of the private robo2-temp workspace and into the public. The integration stack spans four layers:

  1. go-eosio provided ABI decoding fixes for extension fields and name parsing that directly resolved decoding failures in Roborovski’s abicache system
  2. greymass/roborovski received the full open-source codebase migration on January 15, followed by action streaming hardening, API refinements (new /log endpoint, refactored /activity), and data integrity work (CRC checks, WAL key fixes for multi-account indexing)
  3. wharfkit/roborovski advanced from rc2 to rc5, adding activity() and transaction() methods that map to the server-side /account/{name}/activity and /transaction/{txid} endpoints
  4. greymass/unicove began consuming the v2 API on its robo2 branch with a v1 fallback mechanism, plus a new transfers page

The statindex-ui-prototype was created as a Svelte-based test harness for validating action streaming integrations during the same period streaming was being hardened in the main Roborovski repository.

Overview

The Roborovski v2 codebase was open-sourced on January 15, migrated from the private robo2-temp workspace to this new public repository.

V2 remains in development with release candidates ongoing and data format inconsistencies still being resolved.

greymass/unicove

Repository: https://github.com/greymass/unicove Activity: 3 PRs merged, 26 commits Previous Context: See December 2025 for governance features (producer voting, proposals) and search plugin architecture Related Work: See greymass/roborovski, wharfkit/roborovski

Overview

January delivered two parallel tracks: integrating the sentiment voting feature stack into the dev branch, and beginning Roborovski v2 API integration on a separate branch. The sentiment work brought account-level and proposal-level sentiment voting into Unicove alongside a refactored search plugin system. The Roborovski v2 integration introduced a v1 fallback mechanism and a new transfers page.

greymass/go-eosio

Repository: https://github.com/greymass/go-eosio Activity: 4 commits to master Related Work: See greymass/roborovski

Overview

Bug fixes for ABI decoding in the Go library that underpins Roborovski’s abicache system. Roborovski relies on go-eosio for historical ABI decoding — parsing contract ABIs at the correct block height to decode action data. These fixes addressed edge cases in extension field handling and name parsing that caused decoding failures on certain on-chain data.

Repository: https://github.com/wharfkit/roborovski Branch: https://github.com/wharfkit/roborovski/tree/v2 Activity: 5 commits on v2 branch Previous Context: See December 2025 for rc1-rc2 and get_activity client implementation Related Work: See greymass/roborovski

Overview

The TypeScript client library for Roborovski v2 advanced from rc2 to rc5. New activity() and transaction() methods were added, mapping to the server-side /account/{name}/activity and /transaction/{txid} endpoints respectively. These provide TypeScript applications programmatic access to account history and transaction lookup capabilities.
