Zcash’s proposed NU7 network upgrade could affect users holding ZEC in the cryptocurrency’s legacy Sprout shielded pool. According to Cointelegraph, the change is expected to disable version 4 transactions. If implemented, ZEC remaining in the Sprout pool would become unspendable because transactions using that legacy system would no longer be supported. The issue centers on the compatibility of older shielded funds with the proposed November upgrade. Zcash is the related market asset, with the change potentially relevant to holders whose coins remain in the legacy pool. The proposal has not been described here as an already completed network change; its potential impact depends on the implementation of NU7.
