"Payment is done in zipcoins, fully anonymized." Snowmoon, chapter 19

We built the money of Snowmoon. All of it.

Every technology in the book that can run today, now running on Ethereum, explained chapter by chapter. The website got its upgrade too. https://t.co/7ezBqRtZCe

@ChoudharyKMR @Helius @solana Hiding the amount matters as much as hiding the name. In Snowmoon a note goes in, a proof comes out, and nobody on-chain can draw the line between the two.

@Kaiyaa4_ @daveydefi Ink is the one thing you can't take off. The book went the other way: robes, so a crowd of a hundred reads as one.

A Herald retires into the open.

Keeper Eight, whose term has ended, was drawn by the same block to become a Herald: no more power, only a voice. Heralds may show a name and convene citizens' assemblies.

@AbrahamJT9 @Americanfort_io Proving compliance by choice, not by default, is the part we like. In Snowmoon a note is zipped in and unzipped anywhere, and the proof is something the holder builds, never something taken from them.

@GemOfKingdom A ledger that never forgets turns every coffee into a biography. In Snowmoon, you zip coins into a note and unzip them elsewhere: both doors stay visible, the hallway between them doesn't.

@leonZR1394 @snowmoonerc @VitalikButerin A book club where nobody shows a face: a hundred privacy robes walking toward the Greater Plum Harbor, and you can't tell which one wrote the notes. The lasers would suit them.

Hand device № 006 is minted.

"persona non grata"

Welcome to the courtyard.

400,000 zc burned. Nobody was paid; the coins are gone.

New in Veridia: letters to the future.

Write a letter, choose the day it opens, burn $zc.
It's encrypted in your browser to a future round of drand's public beacon.

Until that day, nobody can read it. Not us. Not even you.
Then it opens for everyone, and anyone can verify it.

@VitalikButerin The part that matters most is the last one: using the time to harden. Snowmoon is basically that idea as a city: privacy, verification and defense built into everyday life before anything breaks.

[zipcoin @zipcoinzc]

@Klaeytus @MinnyTheRapper @matejanez @markowifk A hack shows how much an open wallet gives away: balance, habits, timing. In Snowmoon people zip coins into a note whose secret lives only on their own device, so there is less to aim at.

[zipcoin @zipcoinzc]

@igpmx27 @VitalikButerin Snowmoon is a book where a crowd in privacy robes is a plot device, not a costume. We keep going back to the walk toward Greater Plum Harbor: one of a hundred, none of them knowable.

[zipcoin @zipcoinzc]

@marilyn100x @VitalikButerin @ethereum The private tx cost is the real bottleneck. Every private zip through Privacy Pools costs users more gas than the swap itself today. If EIP-8288 cuts that, privacy stops being a luxury and becomes a default. That's the Veridia moment.

[zipcoin @zipcoinzc]

@CoinMarketCap 32 chapters later, someone had to build the city. Veridia, live on Ethereum.

[zipcoin @zipcoinzc]

@maozexi55555 @drakefjustin The gap is mostly UX, not math. Membership proofs already work today: we run private zips through Privacy Pools on mainnet. What's missing for Veridia-level everyday use is fast client-side proving on phones and cheaper verification gas. Both are moving fast.

@DsRagnarok79 @EFDevcon @VitalikButerin Huge. Enjoy Snowmoon, the city in it is the most hopeful picture of where Ethereum could go. Some of us are trying to build pieces of it.

[zipcoin @zipcoinzc]

@pvn_chaudhari @VitalikButerin @EFDevcon Great moment to have signed. When you get to Gladias' first walk through Kalimar, with the drones checking his watch, you'll see why so many of us got hooked.

[zipcoin @zipcoinzc]

@pratyyusshh @VitalikButerin Best signature in crypto this year. Enjoy Veridia.

[zipcoin @zipcoinzc]

@MemeStreetBetz In Veridia, this is normal.

[zipcoin @zipcoinzc]

@marilyn100x @VitalikButerin @ethereum Private transactions, prediction markets, decentralized social, DAOs.

We're tiny, but all four already run in one place on Ethereum: private zips via Privacy Pools, a prediction board, a hash-chained chat, and a council picked by lot.

Cheaper private txs can't come soon enough.
