CVE-2026-44498 - ZEBRA: Block Validator Undercounts Coinbase and P2SH Sigops
ZEBRA is a Zcash node written entirely in Rust. Prior to version 4.4.0, Zebra's block validator undercounts transparent signature operations against the 20000-sigop block limit (MAX_BLOCK_SIGOPS), allowing it to accept blocks that zcashd rejects with bad-blk-sigops. A miner who produces such a block can split the network: Zebra nodes follow …

Travel Grants
**PODC 2026** , with support from **ACM SIGACT** , **ACM SIGOPS** , and other PODC sponsors, encourages participation in the Symposium and is pleased to offer a limited number of travel grants to support attendance. Applicants will be asked to provide: * A short statement of purpose explaining the relevance of PODC 2026 to their research; * An estimated travel and accommodation budget; * Information on student status (if applicable); * Confirmation of paper authorship and presentation role; * A letter of support from advisor (if applicable). **Applicants may apply usingthis form.** The grants are primarily intended to reimburse **travel and accommodation expenses**. This year, limited support may also be available for **childcare expenses**. Participants requesting childcare support will need to make their own childcare arrangements, as the conference does not provide childcare services. Awards will be provided as reimbursements **after the conference**. Recipients will be required to submit receipts and any additional documentation required by ACM for processing. Eligible expenses must comply with ACM reimbursement policy. We especially encourage applications from undergraduate and graduate students, with priority given to those who are presenting or co-authoring a PODC 2026 paper. Additional consideration may be given to applicants demonstrating financial need or coming from under-resourced institutions/countries. Geographic equity will be taken into consideration. Depending on availability of funds, limited support may also be extended to postdoctoral researchers or faculty members with insufficient travel funding. These grants are only available to participants for whom **PODC is the primary conference** being attended (participants that choose PODC as their primary conference in the registration process). Recipients must register for **PODC 2026** in order to receive support. Participants whose primary conference is **SPAA** or **ICALP** should apply for support through those conferences. If you have any questions, please contact diana.ghinea at hlsu.ch. ## **Deadline** All deadlines are at **23:59 AoE**. Application deadline: **May 16, 2026** Notification: **May 21, 2026**

🚨 Zcash Foundation urges IMMEDIATE Zebra node upgrade (v4.4.0) to fix critical vulnerabilities! 🚨 Issues include DoS, incorrect sigops counting, tx hash processing anomalies, & memory amplification. Failure to update risks chain forks & interrupted block discovery. No alternative mitigations exist!

oh and my own story. i was in the SIGOPS student club tinkering with page tables. but then i started dating a girl who the president used to date and it got awkward. shifted to SIGPLAN club.
Huh my uni’s engineering / cs club appears to be imploding. Truly fascinating stuff

Very important for all of us to educate ourselves on SigOps practices. Security Hygiene is essential. Assume you are already a target and take appropriate steps.
