Last week there was no weekly report due to the Chinese New Year holiday and limited working days.
This week, the NBW development team focused on BTCD protocol Taproot contract audit fixes, BTCD protocol Taproot integration work with an external wallet provider, BPoS block production testing, and resolving an ELA-PG cross-chain withdrawal issue. Following the Feb 17 update, BTCD Taproot work continued, with attention shifting toward audit follow-ups and broader wallet support discussions.
Key Work This Week
-
Identified and resolved issues found during the BTCD Taproot contract audit, completed fixes and verification.

This week the team closed out BTCD Taproot contract audit fixes, moved external wallet BTCD Taproot discussions forward, and responded quickly to a community reported PG chain cross-chain withdrawal of ELA issue with a precision fix and coordinated upgrades. The team also addressed a practical BTCD operations issue around penalty order closure for legacy Issuer orders by publishing a new Issuer signing service version and testing closure paths via the PG Issuer.
*Note: PG Chain is operated by NBW as a partner initiative. PG Chain is not a core Elastos product.
