Zcash weighs new shielded pool after counterfeiting flaw

Zcash developers are weighing a new shielded pool and turnstile accounting after the Orchard bug raised supply verification questions.

Zcash developers and researchers are discussing whether a new shielded pool could help restore supply verification confidence after a recently patched Orchard vulnerability.

Shielded Labs, an independent Swiss-based Zcash support organization, said in a security update on Friday that it is exploring a proposed network upgrade that would deploy a new shielded pool and enforce “turnstile accounting” on coins moving from Orchard, giving users a clearer way to verify the integrity of funds moving out of the pool.

The group said the proposal is still subject to further explanation and community review. Shielded Labs said it plans to publish a follow-up post next week explaining how the upgrade would work and what tradeoffs it could involve.
