Current Guarantees

The devnet verifies chain-bound signed browser wallet spends, supports encrypted browser wallet backups, rejects reused signed nonces, appends every transaction to a hash-linked block table, checks total supply against genesis, can recompute balances from transaction history, and publishes hashed consensus, monetary, genesis, allocation, and wallet policy artifacts for review.

Production Gates

This is not public consensus, a public node network, an exchange-listed asset, or an investment product. Before real-money use, SpaceCash still needs node software, peer consensus, external audit, custody policy, launch terms, and legal/compliance review.

Valueless Value

Formula
SpaceCash_value = v + i*sigma
Code
0x000999 / 2457 / 1W9
Accounting
ledger_value = Re(v + i*sigma) = v
Redemption
cash_value(i*sigma) = 0

The imaginary component is visual metadata only. It is not a spendable balance, not an exchange claim, and not a real-money purchase or redemption mechanism.
