Gloria Zhao Steps Down as Maintainer
THE NEWS
Gloria Zhao (glozow) has opened PR #34517 to remove her key from Bitcoin Core's
trusted-keys file, formally stepping down as a maintainer. She was added in July 2022 and served for nearly 4 years.WHAT MAINTAINERS DO
Bitcoin Core maintainers have merge access to the repository. They don't unilaterally decide what gets in -- they merge code that has achieved sufficient review and consensus from the broader contributor community. Their trusted GPG keys are stored in the repo so anyone can verify who merged what.
HER DOMAIN
Gloria was the primary maintainer for the mempool, transaction relay, and P2P subsystems -- arguably the most active and contentious area of Bitcoin Core development in recent years. Her work on package relay and v3 transactions shaped how unconfirmed transactions propagate across the network.
THE PATTERN
Gloria joins a growing list of maintainers who have stepped down: Wladimir van der Laan (2022, after 8+ years as lead), Jonas Schnelli (2021), Marco Falke (2023), Samuel Dobson (2023), and Michael Ford (fanquake, stepped back from some duties). Maintaining Bitcoin Core is a high-stress, often thankless role.

TRAJECTORY
Gloria started contributing in 2020, initially working in Testing and QA. She rapidly moved into the transaction relay and mempool policy subsystems -- the code that governs how unconfirmed transactions are validated, stored, and forwarded between nodes. Within two years she was granted maintainer access.
KEY TECHNICAL CONTRIBUTIONS
BIP 331
Package Relay — allows nodes to evaluate groups of transactions together, solving the CPFP fee-bumping problem for pre-signed transactions
BIP 431
V3 Transactions (TRUC) — opt-in policy restricting topology for reliable fee-bumping, critical for Lightning anchor outputs
MEMPOOL POLICY
Overhaul of the mempool's Replace-By-Fee logic, package CPFP rules, and ancestor/descendant limits
TX RELAY
Orphan transaction handling, transaction download scheduling, 1p1c relay (one-parent-one-child package relay)
WHY THIS MATTERS
Package relay and v3 transactions are foundational infrastructure for Lightning Network. Without reliable fee-bumping for pre-signed commitment transactions, Lightning channels are vulnerable to pinning attacks. Gloria's work directly hardens L2 protocols.
Current Maintainer Roster
| MAINTAINER | GITHUB | ADDED | FOCUS |
|---|---|---|---|
| Ava Chow | achow101 | 2021 | Wallet, GUI, HWI |
| fanquake | fanquake | 2019 | Build, CI, Releases |
| Hennadii Stepanov | hebasto | 2021 | GUI, Build (CMake) |
| Ryan Ofsky | ryanofsky | 2023 | Multiprocess / IPC |
| Sebastian Kung | TheCharlatan | 2026 | libbitcoinkernel |
| Gloria Zhao | glozow | 2022 | Mempool, TX Relay |
BUS FACTOR: MEMPOOL
With Gloria's departure, there is no dedicated maintainer for the mempool and transaction relay subsystem. This is one of the most complex and actively-developed areas of Bitcoin Core. PRs in this domain will need another maintainer to step up, or review and merge velocity will slow significantly.

Maintainer Activity Visualization
DERGOEGGE'S DASHBOARD
Bitcoin Core contributor dergoegge (Niklas Goegge) published a maintainer activity visualization tracking merge commit frequency, review activity, and response times across all current and historical Bitcoin Core maintainers. It provides an empirical view of project health beyond contributor counts.
GLORIA'S CONTRIBUTION PROFILE
Analysis by sorukumar shows 5+ years of sustained output across 10 code domains. Starting from Testing/QA in 2020, she concentrated effort into mempool policy and transaction relay.
