Retrospective pad: https://pad.riseup.net/p/p-a7pwoTTxZzd1ku7AL2

During this sprint we will continue to work towards our goal of having Zebra act as a fully participating and validating node by the time NU5 activates early 2022. In particular by the end of the Sprint we would like for Zebra to:

• Fully validate Orchard, Sapling and Sprout proofs, note commitment trees & anchors,
• Validate miner subsidies and fees
• Validate lock times
• Implement ZIP-203 for transaction expiry
• Close existing connections to outdated peers after a network upgrade activation
