Thanks for making the time to take a look at this today @nprofile…gu0q !
@nprofile…t202 it looks like we have a solution to address the biggest pain points of auctions with a moving deadline. I'll run it by @nprofile…t5pj soon.
Here is an LLM summary of SatsAndSport's idea:
# Moving-Bound Auctions with 1-of-2 P2PK: Symmetric Oracle Paths for Trustless Early Refunds
**Date:** May 22, 2026
**Companion to:** "Extending Auctions Without Imposing a Hard End Time"
**Credit:** SatsAndSports identified the 1-of-2 P2PK approach as a solution to the early-refund and self-rebidding challenges raised in the original article.
---
## The Problem Recap
The moving-bound auction design (described in the parent article) removes the seller-imposed `max_end_at` and replaces it with a bound that moves forward with each new bid. This creates two friction points that the original article identified as open challenges:
1. **Refund latency:** Losing bidders must wait for the full locktime (grace period) to expire before reclaiming their ecash, even if the seller settles within seconds.
2. **Self-rebidding capital waste:** A bidder who raises their own bid must lock the full new amount while the old amount remains locked, temporarily tying up 2x-3x the actual commitment.
Both problems stem from the same root cause: the current lock profile is 1-of-1 P2PK with a timelocked refund. The only way to unlock ecash before `locktime` is via the seller's derived child private key. Losing bidders have no early exit.
---
## The Insight: Symmetric HD Paths with 1-of-2 P2PK
Cashu's NUT-11 already supports M-of-N P2PK locks. A `1-of-2` lock means the ecash can be spent by either of two specified pubkeys — no multisig coordination required, either key alone suffices.
The proposal: **the oracle issues derivation paths for both the seller and the bidder, and the ecash is locked to both of their derived pubkeys as a 1-of-2.**
This is the same path-oracle pattern already used in v1, applied symmetrically.
---
## Current Design: 1-of-1 P2PK + Timelocked Refund
```
┌─────────────────────────────────────────┐
│ Locked ecash (N sats) │
│ │
│ Spendable by: │
│ • seller_child_pubkey (anytime) │
│ derivation path held by oracle │
│ │
│ • bidder_refund_key (after │
│ locktime only) │
│ bidder holds this key directly │
│ │
│ locktime = max_end_at + grace_period │
└─────────────────────────────────────────┘
```
The oracle generates one derivation path per bid:
```
[seller xpub]
│
path: m/.../n
│
seller_child_pubkey
```
- **Seller** has the `xpriv`. Once the oracle reveals the derivation path, the seller derives the child private key and redeems the ecash.
- **Bidder** has a refund key but can only use it after `locktime` expires.
- **Oracle** holds only the derivation path (a sequence of indices). No private key material. Cannot spend.
The problem: the bidder's only early-exit mechanism is the locktime. In the common case (seller settles quickly), the bidder's funds are unnecessarily trapped for the full grace period.
---
## Proposed Design: 1-of-2 P2PK with Symmetric Paths
```
┌─────────────────────────────────────────┐
│ Locked ecash (N sats) │
│ │
│ Spendable by EITHER (1-of-2): │
│ • seller_child_pubkey │
│ (oracle path A) │
│ • bidder_child_pubkey │
│ (oracle path B) │
│ │
│ Fallback (if oracle disappears): │
│ • bidder_refund_key after locktime │
└─────────────────────────────────────────┘
```
The oracle now generates two derivation paths per bid — one against each party's HD key:
```
Oracle's HD key tree (per bid):
[oracle xpub]
/ \
path A: m/.../0 path B: m/.../1
/ \
seller_child_pubkey bidder_child_pubkey
```
### Key derivation for each party
- **Seller** holds their own `xpriv`. When the oracle reveals path A, the seller derives `seller_child_privkey = derive(xpriv, path_A)` and can spend.
- **Bidder** holds their own `xpriv`. When the oracle reveals path B, the bidder derives `bidder_child_privkey = derive(xpriv, path_B)` and can spend.
- **Oracle** holds only the path indices (e.g., `m/30408'/0'/0'` and `m/30408'/0'/1'`). No `xpriv` material from either party. **Cannot derive any private key. Cannot spend. Cannot steal.**
### The trust model
```
┌──────────────┐
│ ORACLE │
│ │
│ Knows: paths │
│ Can't: spend │
└──────┬───────┘
╱ ╲
path A ╱ ╲ path B
╱ ╲
┌──────┴──────┐ ┌──────┴──────┐
│ SELLER │ │ BIDDER │
│ │ │ │
│ Has: xpriv │ │ Has: xpriv │
│ Needs: A │ │ Needs: B │
└──────────────┘ └──────────────┘
```
The oracle's role is purely **informational**: it decides *which* path to reveal to *which* party. It controls the routing of funds without ever being able to take them.
**What the oracle CAN do:**
- Reveal path A to seller → seller claims the ecash (settlement)
- Reveal path B to bidder → bidder reclaims the ecash (early refund)
- Refuse to reveal any path → parties wait for locktime fallback (DoS, not theft)
- Reveal the "wrong" path → misroutes funds (seller gets refund, or bidder gets payment)
**What the oracle CANNOT do:**
- Derive either party's private key (holds no `xpriv`)
- Spend the locked ecash (no key material)
- Steal funds (can only redirect them to one of the two intended parties)
- Create or destroy ecash (bearer asset, mint-controlled)
This is the same threat model as v1. The oracle is trusted for **liveness** (it must reveal paths) and **correctness** (it reveals the right path to the right party), but NOT for **custody** (it cannot take funds).
---
## How This Solves the Open Challenges
### 1. Instant refunds for losing bidders
```
Auction ends. Winner determined.
For each LOSING bid:
Oracle reveals path B to the bidder
→ Bidder derives child privkey from xpriv + path B
→ Bidder redeems ecash from mint
→ Refund is INSTANT. No locktime wait.
For the WINNING bid:
Oracle reveals path A to the seller
→ Seller derives child privkey from xpriv + path A
→ Seller redeems ecash from mint
→ Same as today.
```
The locktime + refund key still exists as a **fallback**. If the oracle disappears or is unresponsive, every bidder can still reclaim after locktime expires. But in the normal case (oracle online), refunds happen immediately.
This means the grace period can be set generously (hours or even days) to handle seller downtime or mint downtime, **without penalizing losing bidders**. In the happy path, everyone gets their funds quickly regardless of the grace period length.
### 2. Capital-efficient self-rebidding
```
Bidder has a 5,000-sat bid (lock 1, 1-of-2 with paths A1/B1).
Bidder wants to raise to 8,000 sats.
1. Bidder requests new grant from oracle
→ Oracle generates paths A2/B2 for the new bid
2. Bidder locks 8,000 sats in new 1-of-2 lock (lock 2)
3. Bidder publishes new bid event
4. Oracle sees the new bid supersedes the old one
5. Oracle reveals path B1 for the OLD lock to the bidder
→ Bidder instantly reclaims the 5,000 sats
Net result: 5,000 recovered + 8,000 locked = only 8,000 outstanding.
Old lock is resolved immediately, no locktime wait.
```
The oracle's knowledge of which bids are superseded allows it to release the bidder's path for old locks as soon as a higher bid is confirmed. The bidder gets their capital back immediately and can reuse it.
### 3. Generous grace periods without penalty
In v1, the grace period directly determines how long losing bidders wait. A 1-hour grace means a 1-hour wait. This creates a tension: short grace = risky for seller, long grace = painful for bidders.
With 1-of-2 P2PK, the grace period is a **worst-case fallback**, not the normal-case latency:
- **Normal case** (oracle online): losing bidders get refunds via path B within seconds of settlement. Grace period length is irrelevant.
- **Worst case** (oracle offline): losing bidders wait for locktime (same as today). A longer grace period provides more safety for the seller without making the common case worse.
---
## Comparison: v1 vs. Proposed
| Aspect | v1 (current) | 1-of-2 proposal |
|--------|-------------|-----------------|
| Lock type | 1-of-1 P2PK | 1-of-2 P2PK |
| Pubkeys in lock | seller_child only | seller_child + bidder_child |
| Bidder refund trigger | locktime expiry only | oracle-revealed path B (instant) OR locktime (fallback) |
| Refund latency (normal case) | full grace period (1+ hour) | seconds |
| Self-rebid capital efficiency | must lock full new amount, old lock trapped | oracle releases old lock path B immediately |
| Grace period tradeoff | long grace = long bidder wait | long grace = safe fallback only, no normal-case penalty |
| Oracle trust | trusted for liveness + correctness, not custody | **identical** — same threat model |
| Bidder key requirement | single refund key (any secp256k1) | HD key (xpriv) for path derivation |
| Fallback if oracle disappears | bidder reclaims via locktime + refund key | **same** — locktime + refund key still in lock |
| Cashu mint compatibility | NUT-11 with P2PK + locktime + refund | NUT-11 with multi-pubkey P2PK + locktime + refund |
---
## What Changes in the Implementation
### NUT-11 lock construction
Current (v1):
```json
[
"P2PK",
{
"nonce": "<random>",
"data": "<seller_child_pubkey>",
"tags": [
["sigflag", "SIG_INPUTS"],
["locktime", "<locktime_unix_seconds>"],
["refund", "<bidder_refund_pubkey>"],
["n_sigs_refund", "1"]
]
}
]
```
Proposed (1-of-2):
```json
[
"P2PK",
{
"nonce": "<random>",
"data": "<seller_child_pubkey>,<bidder_child_pubkey>",
"tags": [
["sigflag", "SIG_INPUTS"],
["n_sigs", "1"],
["locktime", "<locktime_unix_seconds>"],
["refund", "<bidder_fallback_pubkey>"],
["n_sigs_refund", "1"]
]
}
]
```
Key differences:
- `data` field contains both pubkeys (comma-separated or as per NUT-11 multi-pubkey convention)
- `n_sigs: 1` explicitly set (1-of-2: either key suffices)
- `locktime` and `refund` remain as the oracle-disappears fallback
### Oracle grant flow
The oracle's `request_path` response expands from:
```json
{
"derivationPath": "m/30408'/0'/0'",
"childPubkey": "<seller_child>",
"grantId": "..."
}
```
To:
```json
{
"derivationPathA": "m/30408'/0'/0'",
"sellerChildPubkey": "<seller_child>",
"derivationPathB": "m/30408'/0'/1'",
"bidderChildPubkey": "<bidder_child>",
"grantId": "..."
}
```
The oracle still reveals paths only at settlement time:
- **Settlement:** oracle reveals `derivationPathA` to seller (same as today)
- **Refund:** oracle reveals `derivationPathB` to the losing bidder (new capability)
- **Rebid:** oracle reveals `derivationPathB` for the superseded bid to the bidder (new capability)
### Bidder key setup
In v1, bidders only need a refund pubkey (any secp256k1 key). In the 1-of-2 design, bidders need an HD key (`xpriv`/`xpub`) so they can derive child private keys from oracle-revealed paths.
This could be:
- The bidder's Nostr key (if it's an HD key)
- A dedicated auction HD key generated at first bid
- Derived from the bidder's NIP-60 wallet key material
The auction event would carry a `bidder_p2pk_xpub` in addition to the existing `p2pk_xpub` (seller), or a convention could be established where the bidder's xpub is communicated during the path request.
---
## Open Questions
1. **Bidder xpub source:** Where does the bidder's HD key come from? Options include: derived from Nostr key, derived from NIP-60 wallet, generated per-auction, or generated per-bid. The tradeoff is between privacy (fresh key per bid) and recoverability (deterministic from existing key material).
2. **Oracle path revelation timing:** When exactly does the oracle reveal path B to losers? Options: immediately after settlement, on request from the bidder, or batch-revealed for all losers at once.
3. **Rebid race condition:** If a bidder submits a rebid and the oracle releases path B for the old lock, what prevents the bidder from reclaiming the old funds AND cancelling the new bid before it's confirmed? The oracle should only release path B after the new bid is published and verified.
4. **Mint compatibility:** Not all Cashu mints may support multi-pubkey P2PK locks. The auction's trusted mint list should be validated for 1-of-2 support before the auction is created.
5. **Settlement policy versioning:** This would likely ship as `cashu_p2pk_path_oracle_v2`, coexisting with v1 auctions on the same relays. V1 auctions continue to settle under v1 rules.
---
## Summary
The 1-of-2 P2PK pattern applies the existing path-oracle trust model symmetrically: the oracle creates derivation paths for both the seller and the bidder, and the ecash is locked to both derived pubkeys. The oracle controls *who* can access the funds by choosing which path to reveal, but can never *take* the funds itself.
This solves the three biggest friction points in the moving-bound auction design:
- **Losing bidders** get instant refunds (no locktime wait in the normal case)
- **Self-rebidders** recover old locks immediately (no capital waste)
- **Grace periods** can be generous for safety without penalizing anyone in the happy path
The trust model is unchanged: the oracle is trusted for liveness and correctness, but never for custody. If the oracle disappears, the locktime + refund fallback works exactly as in v1.

An amateur radio satellite based TollGate already exists - @nprofile…kq7x built it. Its just a question of time till its compatible with the TollGate protocol and accepts bearer instruments 😃

It seems to me like DNN has the same set of tradeoffs as noDNS, but DNN has a global state thanks to Bitcoin. Where does DNN store the IP address that a name resolves to? Does it use nostr for this? Apologies if you already explained this..

When trying to understand new systems, I like to try to place them on that triangle to reason about the tradeoffs...

Aah, so the name is human readable, but the TLD is a large random string - ie. the entropy that makes it secure. That makes sense. Does this mean I need to check the large random string like checking an npub to make sure I'm being redirected to the right IP address?

2025-12-26 14:48:45 UTC

- reply

Thanks for the patient explanation @nprofile…u4cn. Getting a sense of the tradeoffs helps a bit, but I must admit that I still need to give it more thought before I fully grock your system. What do you mean by "no name scarcity"? Can others claim the same name that I have already claimed? I guess the cost of doing a Bitcoin transaction is what rate limits my ability to claim as many names as I want right?

2025-12-25 13:09:58 UTC

- reply

That sounds really promising! It makes sense that Bitcoin would be the anchor for a global naming system, because Bitcoin is the closest approximation to a truly global database that we have.
Have you heard of the spaces protocol? I managed to set up the DHT client on my computer, but haven't tried securing and/or resolving a name yet. Would be interested in your thoughts...

## BudaBit Demo Day application
### Title: TollGate auto connect with data measurement
Pitch:
TollGates turn on, connect to eachother automatically and start reselling access to the gateway while measuring data rather than time. The user can connect other devices to the password protected SSID of their TollGate to get regular WiFi UX without needing software that tops up their session on their user devices.

@nprofile…zqac also knows a lot about this stuff. If only he had a proxy running on main net already.
Oh, by the way @nprofile…zqac I think I finally understand why latency is important even though bitaxes are happy to run at a loss in certain scenarios (like when it improves the UX of something). Apparently pools reject high latency shares because miners who do care about their margins don't want to be mining with high latency miners who don't care about margins.
Does this mean we need special pools for high latency miners or am I overlooking something?

2025-12-12 18:32:11 UTC

The smallest useful thing you can broadcast is the latest block hash. The second most useful thing is the latest block template (see sparse pool by @nprofile…924l). These things can be obtained for free from block stream because it's a one way broadcast of data that everyone cares about.
Traffic from miners is different from traffic from Netflix, because the miners have very little traffic, but the traffic that they do have is very valuable on a per Byte basis.
Your two way link is especially interesting for miners who want to get their nonces to a pool ASAP. These miners already have a block template from spares pool or from block stream, but they need transportat to get their nonces out reliably. Depending on the energy source, they may not have an economically viable uplink, unless if they pay per Byte to use your satellite dish..

I guess a question of efficiency. Having things pre-installed makes sense if I only need them briefly and a large portion of my costs are setup & teardown. Perhaps what your making here is a framework for people to make their custom pre-installed environment...

I like the idea of being able to pay for small amounts of compute and/or small periods of time. However, my concern is that the service might be specific to a very niche use case.
Can I run anything I want on it in the same way that I would with a VPS that I rented for 3 minutes?

Is this whole thing a layer on-top of VMs/containers for SATs? I still think there is value in having super generic machines that users can run whatever they want on...

Absolutely, and this machine is probably more beefy, so it should be able to run CDK..

Aah yes, if I recall correctly, at the time we thought stage 2 wasn't necessary and we thought wallets were just doing it for the sake of storing unlocked proofs. I guess stage 2 did have a purpose which we were overlooking at the time then..

Meeting notes:
Dimi x86 based TollGate that runs in a VM and works over wireguard
Notes:
The x86 image is useful for machines like start9. Wireguard is required for the enterprise ISP features that will transform Elzonte in no time.
Could add reticulum to this. It deals with double NATing etc.
Compression for smaller routers:
https://github.com/OpenTollGate/tollgate-module-basic-go/pull/63
Merged and released dual SSID:
https://github.com/OpenTollGate/tollgate-module-basic-go/commit/e9aa0356a8691a9c32fe3bd3fa06b32e307d0ae9
Notes:
You can now connect to your TollGate's second password protected SSID to get internet access from your own router without paying it. This is good for your UX.
New version of release explorer:
https://releases.tollgate.me/
Notes:
Beautiful new release explorer. Has search. Can see raw events. Architectures are now in a drop down menu. The compressed package will be shown as a separate download button for the same architecture.
Conferences:
