FCMP++ features:

• Massive anonymity set increase — sender anonymity set goes from ~16 to over 160 million per transaction input (a 10-million-fold increase), giving Zcash-level sender privacy
• Carrot addressing protocol and new addresses — new address scheme with new view keys (also fixes issues like the burning bug and Janus attack, and enables outgoing view keys and offline address generation)
• Transaction relay v2 — bandwidth-efficient transaction relay (32-byte tx IDs instead of full ~10 KB transactions)
• RandomX v2 — improved ASIC resistance
• Proof-of-work commitments — better DoS/spam resistance for nodes; easier SPV-style wallet verification since proof-of-work can be checked without running a full RandomX hash (important for resource-constrained devices)
• Vastly improved multisig — no need for all parties to be online (or recently online) to sync key images; far fewer interaction rounds between participants
• Simplified hot/cold wallets and hardware wallet support — cold signing and vaults become much easier (part of why projects like XMR Bazaar and hardware wallet integrations struggled before)
• Signing before proving (decoupled signatures/proofs) — transactions can be signed ahead of time and membership proofs attached later, with no on-chain fingerprint distinguishing old vs. new signatures
• Transaction chaining / conditional spends — enables simple payment channel-style constructions (lock-time conditions, atomic-swap-style escapes) — an open PR by Teodor adds a basic version
• Faster wallet scanning — via the mx25519 library (~40% faster scanning compute in the assembly backends)
• Fungibility/privacy parity — closes the "Zcash is more private" sender-side gap; amounts and receivers were already protected

several of these (multisig relief, hot/cold simplicity, sign-then-prove) are the exact features Serai DEX is waiting on before launching its Monero integration.

Yes, this is such a good episode

A great overview of the upcoming hardfork including features, and even discussing the prospective next steps after FCMP++

hbs has been working on it

He's actually giving a workshop on this topic this weekend at Dark Prague

https://speak.darkprague.com/dp26/talk/LQJEYC/

There's still active development on it too, but just seems to need more polishing

This is a response I had when someone said that Thorchain wouldnt be a BIG addition:

Total lifetime volume of Thorchain: $124 Billion
Yesterday's volume: $30.6 million

Near intents lifetime volume : $27 Billion
Yesterday's volume: $68 million

Total lifetime volume of retoswap:
$200 million (back in January)
Yesterdays total liquidity: $6.4 million

basicswap total liquidity: $122,000

This isn't a 1:1 comparison but can't find perfectly overlapping metrics

But adding Thorchain will open a HUGE door

I hope there aren't more security issues, but the volume that thorchain will open up will definitely be the biggest market, by a huge margin, that isn't a CEX

We try and best solve this with our Re-router service (https://sovereignstack.tools/rerouter/). We successfully ship items abroad but it varies depending on each order. (Item, size, dimension, shipping address being used, border inspection, Country). We work with customers regarding sourcing/shipment/delivery/reception. We try and find it locally rather than shipping from abroad.

We wrote a blogpost back in '21 on private mailing options (https://sovereignstack.tools/how-to-thinking-about-private-mail-drops/) but it's more US-centric. Its helpful to get an idea of what you should think about.

A few other considerations:

• What's the availability of the item? Is it available at different vendors?
• Can the item be acquired locally?
• What's the country's Customs enforcement like?
• Does the country offer no-kyc locker/package delivery solutions?

If you're a nomad this may be more difficult but befriending local businesses or using hotels as shipping addresses are a good work around.

There is no one-size fits all, believe me, I wish there was.

For the items to be delivered to an amazon locker, they need to be "shipped by Amazon" or "fulfilled by Amazon"

We can also ship other amazon items to you via our re-router (https://sovereignstack.tools/rerouter/), it will come direct to the shipping address you provide instead

There is no minimum or maximum order amount

As of right now we're servicing US lockers/counters before we decide to expand internationally.

If the item is rejected (because its too big of an item, or not shipped by Amazon), Amazon won't allow us to place the order to the locker/counter location reject the order. There are no refunds once we've placed the order (unless the item doesn't get picked up). We verify the order before placing with the customer. If the item doesn't get picked up in 3 days, it gets returned and we can refund funds or re-place the order.

We keep the one-time payment fee to prevent abuse from people ordering and cancelling repeatedly.

You need an amazon account to use that service you linked

You dont need an amazon account with us

We'll start in the US but we'll be looking to expand after a few months under our belt
