Happy Birthday Zcash 10 #008
Message in a Bottle
✦ Only You Can Read It
A crystal bottle in the sand, sealed with a gold Zcash wax seal; the letter inside glows but cannot be read.
- Every shielded note carries an encrypted 512-byte memo.
- Only the recipient, or someone they give a viewing key, can read it: this postcard lives in exactly such a memo.
✓ In the collection’s signed manifest
✓ Bound to the collection key and this image
✓ Issued on Zcash, block 3,501,212
