Snapshots

A dataset you can sum yourself, its checksum, the Merkle root over it, and the command that reproduces both. Do not take the proof page on trust; recompute it.

◐ Fixture data · algorithm real, entries are not

The tree below is genuine and every proof it produces verifies. The entries are fixtures, and no root has been anchored to any chain. A snapshot of the live ledger cannot be published until balances are integers behind one guarded writer — a dataset drawn from a float ledger with 124 writers would not reproduce twice, and a reader who fails to reproduce a published root has learned something false about our competence rather than something true about our data. Verify the mechanism here; do not treat it as evidence about the ledger.

What is inside the liability

Σ of every entry amount in the published snapshot, over obligation-class assets only — the ledger classes REWARD_CURRENCY and PARTNER_CREDIT. Commodity units are excluded and named. Signed integer minor units throughout, summed as BigInt — a total in the hundreds of millions of minor units exceeds what a double holds exactly. Reproduce it from the JSONL on /snapshots/.

Asset	Ledger class	In the liability	Basis
Flashy Gold FG	Reward currency	Counted	Redeemed against a stated obligation for stated goods, so every outstanding unit is something the group owes. See /redemption/.
Wheat WHEAT	Commodity unit	Excluded	Produced and consumed inside the economy. Nothing can be presented to the group in exchange for it, so it is not a debt.
Stone STONE	Commodity unit	Excluded	A building input, destroyed on use. Inventory inside the economy, never a claim.
Wood WOOD	Commodity unit	Excluded	A building input, destroyed on use. Inventory inside the economy, never a claim.
Iron IRON	Commodity unit	Excluded	Spent to initiate and to defend raids, destroyed on use. Inventory inside the economy, never a claim.

The class names are the ledger’s own — REWARD_CURRENCY, COMMODITY_UNIT, PARTNER_CREDIT — so the perimeter published here and the field stored on the asset are one fact rather than two. Commodities do not exist yet. The rule is written now so that adding the first one is a row in the asset registry rather than an argument about what a published total meant last quarter.

∅ Unavailable · outstanding liability, book-wide

The published snapshot is a sample, and the live book stores amounts as floats behind 124 writers. A book-wide total drawn from it would not reproduce between two reads. Blocked on CYG-LED-1 — integer minor units — not on effort.

How the root is built

Specified rather than described, so it can be reimplemented in a language we did not choose. A root only we can compute is a number we assert, not a number you check.

canonical(entry) = id | asset | type | source | amount_minor | recorded_at
                   joined with U+007C, no padding, no whitespace

leaf(entry)      = SHA256( 0x00 || utf8(canonical(entry)) )
node(left,right) = SHA256( 0x01 || left || right )

leaves sorted by id, ascending, byte-wise
odd nodes are promoted to the next level, never duplicated

tenant(id,root)  = SHA256( 0x02 || utf8(id) || 0x1f || root )

tenants sorted by id, ascending, byte-wise
one day root over every tenant subtree — one transaction per chain per day

Why the 0x00 / 0x01 prefixes

Domain separation. Without it, an internal node digest can be presented as though it were a leaf, and an inclusion proof forged for an entry that was never in the tree.

Why odd nodes are promoted

Duplicating the last node to pad a level lets two different entry sets produce the same root — the flaw behind CVE-2012-2459. Promotion carries the node up unchanged.

Reproduce it

# the proof for one entry, self-contained
curl -s https://flashynetwork.com/api/v1/public/ledger/proof/gl_01K2F7QW3M/ | jq

# rebuild the root from the dataset
npx tsx scripts/anchor.ts

The self-check in that script proves every entry against the root before it will print one, so a broken tree fails here rather than in front of a reader who could not reproduce a published number.

Where roots get published

Target	Network	Why it earns a row	State
TON Testnet	testnet	The strategic home, on testnet first. Proves the pipeline against the chain our holders are closest to, at no cost and with no claim that it is production.	IN BUILD
Base Sepolia	testnet	The credibility anchor, on testnet first. EVM, so the deepest auditor and tooling pool. Proving the pipeline here costs nothing and means the first mainnet root is not the first root we have ever produced.	IN BUILD
Avalanche Fuji	testnet	Avalanche on testnet first, for the same reason as Base Sepolia: the first mainnet root must not be the first root the pipeline has ever produced. EVM C-Chain, so it reuses the calldata format and the on-chain verify() unchanged.	IN BUILD
TON	mainnet	Where the people who hold Flashy Gold already are. Telegram-native, and the chain that makes the settlement record legible inside the product rather than only to auditors on a desktop.	NORTH STAR
Base	mainnet	The one an integrator checks. Median fee near two cents, so a daily root is on the order of seven dollars a year regardless of how many entries the day contained.	NORTH STAR
Avalanche C-Chain	mainnet	Sub-second deterministic finality and a cent-scale fee, so a daily root is confirmed in one block a reader can watch rather than a probabilistic wait. Same 32 bytes and same verify() as every other EVM target — the cost of adding it was one config row.	NORTH STAR

No contract is deployed on any of them. A root is 32 bytes in a transaction — it needs no contract, and deploying one named after Flashy Gold would create exactly the artifact /no-contract/ exists to say does not exist.
