Zcash’s NU7 upgrade activates on mainnet, bringing faster block production and changing how transaction fees are handled. Multiple outlets report that NU7 reduces the target time between blocks, and that it includes updates intended to affect private payments and fee economics.
A key component of NU7 is the Network Sustainability Mechanism. Coverage across sources says the mechanism removes a portion of each block’s transaction fees from circulation and recycles value for future block rewards, with details pointing to 60% of fees being removed and reissued later, while also staying within the broader Zcash supply limit. CoinDesk also emphasizes that the upgrade speeds up private payments by reducing the work required for “work wallets” to find private payments.
Outlets differ slightly in emphasis: some foreground block-time changes, others focus on private-payment performance, and others highlight the sustainability or dev-funding debate implied by how removed fees are earmarked for later rewards.
