Aere Network public source. Everything here can be checked against the live chain (chain id 2800, https://rpc.aere.network). Scope note, stated up front rather than buried: consensus on chain 2800 is classical secp256k1 ECDSA QBFT. The post-quantum work in this repository is at the signature, precompile, account and transport layers. Nothing here makes the consensus post-quantum, and no document in it should be read as claiming so.

/**
|
|
* @title AerePointsLedger — AERE Season 1 "Altitude" non-transferable points
|
|
* @notice A CREDIT-ONLY, NON-TRANSFERABLE ledger of "Altitude Points" (AP).
|
|
*
|
|
* HARD SAFETY DESIGN — AP is NOT a token and can never become one:
|
|
* - transfer / transferFrom / approve HARD-REVERT (NotTransferable). AP can
|
|
* never move between accounts, so it can never trade as a shadow token.
|
|
* - There is NO burn, NO redeem, NO conversion, NO "claim your tokens"
|
|
* path anywhere in this contract. AP is a scoreboard, nothing else.
|
|
* - Only Foundation-authorized attestors may `credit`. There is no mint()
|
|
* callable by users and no way for AP to leave an account.
|
|
*
|
|
* HONESTY / DISCLAIMER (must accompany any user-facing surfacing of AP):
|
|
* Altitude Points are NOT a token, carry NO guaranteed value, and confer
|
|
* NO right to returns. Any future reward depends on the network growing
|
|
* and is not promised. There is no listing.
|
|
*
|
|
* ERC-20 read shape (name/symbol/decimals/balanceOf/totalSupply) plus a
|
|
* mint-style Transfer(address(0), account, amount) event are emitted purely
|
|
* so block explorers / the AERE indexer can display balances. The WRITE side
|
|
* of ERC-20 is deliberately bricked.
|
|
*
|
|
* Owner = Foundation multisig. Ownable only manages the attestor allowlist;
|
|
* the owner cannot move, mint to itself for transfer, or reduce balances.
