Two gaps the owner panel left open. First, a hidden TLD was only a UI
gate: anyone could still broadcast a REG under it and every indexer
admitted it. Second, there was no way to sell a name without trusting
the other side.
Co-sign rule (consensus, applied in lockstep by bns.js and
resolver-web.js): a REG under a TLD whose records at that height say
policy "cosign" or hidden 1 is indexed only if the transaction carries
the TLD's own certificate. The certificate can only be spent by the
owner's key and is re-issued to them in the same transaction, so it is
a co-signature nobody can forge and nothing is consumed. The TLD map
now keeps the TUPD timeline so policy is evaluated at the REG height.
Owners register under their private TLDs with the certificate added
from their own wallet; third parties under a "cosign" TLD build the
full transaction, sign their inputs and queue it at /api/cosign, where
the owner approves it from the dashboard (signCosignRequest refuses to
sign unless the certificate returns to the same locking script).
Marketplace: a listing is the seller's certificate input plus a price
output signed SIGHASH_SINGLE|ANYONECANPAY, stored by the gateway as a
bulletin board (/api/market, verified against the on-chain owner and
pruned when the certificate moves). The buyer completes it in one
transaction, so the seller is paid exactly when the name moves.
Cancelling also spends the certificate once so the offer is void.
Site: market.html, Sell sub-tab and Pending approvals in the portal,
Market link in nav and footer, six dictionaries extended, cache tags
bumped. Verified on chipnet: cosigned.sc registered by a throwaway
wallet through the queue with the .sc certificate back at the owner;
aloevera.test listed and delisted through the API.
Ariadne's resolver-web.js copy and the mobile Bns.java port still need
the co-sign rule; until then they admit REGs this index rejects.
A TLD owner needed to run their namespace without the operator: set what
every name under the TLD sells for, take the TLD off the public registry
for a while, and still register names under it themselves.
Both settings live on chain in the TLD's TUPD records (`price`, `hidden`)
because changes are rare and every client already walks the TLD beacon.
The gateway's /api/tlds now carries records, owner, price_usd and
hidden_by per TLD; pricing.js quotes the owner price ahead of the length
tiers and only trusts a TLD_BEACON-sourced list; the register flow refuses
hidden and frozen TLDs for the public but lets the owner through at the
platform share only (the 90% owner cut would be paid to themselves). The
portal's TLDs tab loads real holdings, shows price and on/off state, and
gives each TLD a one-click switch, a price/policy editor and an inline
"register a name under .tld" form. Docs and the design table describe the
two new records.
TLD price tiers (pricing.js):
1 char $500 (was $10)
2 char $250 (was $8)
3 char $150 (was $6)
4-6ch $100 (was $5)
7-10ch $50 (was $5)
11+ch $25 (was $4)
Payment approval (register-flow.js):
New stepApprove(...) gates the actual sign+broadcast on an explicit
user gesture — PIN pad when a PIN blob exists on this device, wallet
password otherwise. Same "3 wrong PINs → wipe, fall back to password"
behavior as the sign-in unlock step. Wired between stepConfirm(Tld)?
and stepRegister(Tld)? so both name mints and TLD mints require
approval even when the wallet is already in memory.
tld.html fee card: reflects the new $25–$500 range instead of the
"≈ 1,250,000 sat · ≈ $5" placeholder.
Single source of truth (js/pricing.js) mirrored on landing, tld.html
and the mint flow — same label always shows the same price everywhere.
Name tiers (label part):
1 char $5.00 premium-1
2 chars $3.00 short-2
3 chars $2.00 short-3
4–5 chars $1.00 standard
6–7 chars $0.50 long
8–16 chars $0.25 extended
17+ chars $0.10 very-long
all-digits ×0.5 (less brandable)
contains hyphen ×0.7
TLD tiers (label part):
1 char $10.00 premium-1
2 chars $8.00 short-2
3 chars $6.00 short-3
4–8 chars $5.00 standard
9+ chars $4.00 long
Rendering:
- Landing #search-results: acid-tinted price badge on each available
row; grid grew a fourth column so name + badge + price + button
all sit on one line
- tld.html search result-card: same price badge next to the Register
button on available TLDs
- tld.html registered-TLDs table: new 'Mint price' column showing the
tier price for every registered TLD, so buyers see the pricing
ladder next to concrete examples
Mint pipe:
- startFlow(name)/startTldFlow(label) resolve the label price via
window.siriusPricing (default) but honour opts.serviceFeeSats when
the caller passes one — leaves the door open for coupons /
operator discounts / oracle overrides in a future revision without
reshuffling call sites
- The overridden service fee is threaded through quoteRegistration
AND registerWithBuiltInWallet/registerWithExternalWallet so the
confirm screen and the on-chain output agree
Chipnet placeholder rate (250,000 sat/USD) stays in pricing.js;
mainnet will swap in a live BCH/USD oracle. Operator-side discounts
and coupon codes are the next iteration — deliberately not disclosed
in this shipping copy.
