2021 Sprint 21 2021.11.02 - 2021.11.15

Retrospective pad: https://pad.riseup.net/p/UHGI-tq-9bnFPIBBME7K

During this sprint we will build on our first beta release by continuing to work towards our goal of having Zebra act as a fully participating and validating node by the time NU5 activates early next year. In particular by the end of the Sprint we would like for Zebra to:

• Fully validate Orchard proofs, note commitment trees & anchors,
• Fully validate Sprout and Sapling note commitment trees and anchors,
• Support parsing of addrv2 messages as per ZIP-155,
• Calculate block subsidies

By the end of the sprint we would also like to fix a number of security issues that could pose a DDoS risk or otherwise negatively impact other nodes on the network.
