Feb 1, 2026February 2026: Tellor Layer (tellor-io/layer) delivered hardening of the vote extension input path by enforcing strict size limits and validation. Key feature delivered: vote extension interface with size enforcement and trailing data rejection, improving data integrity, security, and reliability of the voting system. Major bugs fixed: blocked trailing data and prevented oversized vote extensions at the interface boundary, reducing attack surface and data corruption. Overall impact: stronger voting data integrity, more robust validation, reduced maintenance risk, and clearer failure modes. Technologies/skills demonstrated: interface design, JSON payload validation, security hardening, commit hygiene, and collaborative code review as reflected in the final commit 2663b86358c84c3c3338f7bb0ac308139dad9079.

Dec 1, 2024December 2024 – tellor-io/layer: Implemented governance-controlled snapshot limit for the bridge module to cap attestation requests per block. The feature required updates to genesis state, transaction definitions, and keeper logic, and is controlled via governance parameters with a getter for visibility. This work enhances stability under load and reduces operational risk by preventing bursty attestation traffic. Key commits: 0efe1cc0eb041264091bd7d684c711f682ddbea6 (feat: snapshot limit param set by gov (#453)) and 09cb346ddf9b8171db7cb8f6d375a102692f6ea7 (feat: snapshot limit getter (#458)).
