Zcash is preparing to implement its NU7 network upgrade in November, which will disable version 4 transactions. According to CoinTelegraph, this change will render funds held in Zcash’s legacy Sprout shielded pool unspendable.
The upgrade aims to phase out older transaction formats to improve network efficiency and security, but users with ZEC stored in the Sprout pool will be affected by the inability to move those funds post-upgrade. This marks a significant shift for holders relying on the legacy shielded pool.
For Japanese investors, who closely monitor privacy-focused cryptocurrencies in the FX and crypto markets, this upgrade signals important considerations regarding asset accessibility and network protocol changes affecting token usability.
