NU5 activates on mainnet, eliminating trusted setup and launching a new era for Zcash
NU5, the first major upgrade since November 2020, includes the launch of the Orchard shielded payment protocol, utilizing the Halo proving system to remove reliance on complex setup ceremonies.
Zcash Proof-of-Stake Research
In August, ECC shared its rationale for moving Zcash from a proof-of-work consensus mechanism to proof-of-stake.
BOSL exceptions added for Zcash projects and friendly forks
When ECC announced the release of zcashd 5.0.0, we indicated our intent to add two general exceptions to the BOSL license so that our partners and friendly forks could use the Orchard technology deploying in NU5 in a manner consistent with their current licensing choice.
ZSAs and Zcash Economics
Over the last 10 months, ECC published a series of blog posts on our work exploring Zcash Shielded Assets (ZSAs), including our plans to perform an economic analysis of various fee mechanisms that could be employed alongside ZSAs.
