BTUCOIN — PoS Hybrid (Deposit, Withdraw, Stake)

Studio ledger in play · PoS settlement later · deposit / withdraw bridge · optional stake · never power

This chapter locks how BTUCOIN can sit on a Proof of Stake settlement layer without breaking Year‑1 play authority. Year 1 stays a studio ledger + market-price feed. PoS is the designed TBD-038 path: hybrid deposit / withdraw / optional stake — not a miner or validator inside Unreal.

Note

Hybrid. Match / objectives / convert / Marketplace remain on the MonetaryPlatform studio ledger (fail-closed). PoS secures transferable BTUCOIN after withdraw. The UE5 client never runs consensus. Studio 51% mint share is never player-withdrawable. Looks and LUMENAR rules unchanged — BTUCOIN still never tenders Marketplace SKUs.

Lock plate. Play ledger stays authoritative. PoS is settlement + optional stake. Bridge is gated. Never Combat power.

Phases

Phase	What ships
Year 1	Studio-operated BTUCOIN ledger + external market-price feed. Settlement P = max(floor, market). Play/cash mint M = V / P; convert uses same P (LUMENAR flat for V). No on-chain client, wallet seed, or exchange listing in C++.
PoS hybrid (TBD-038)	BTUCOIN issued / bridged on a PoS host (existing L1, L2, or app-chain). Deposit + withdraw. Optional on-chain stake. Wallet chrome for bridge status.

Preferred host shape: issue on an existing PoS network or PoS L2 (inherit validators). Building a custom PoS L1 is out of Year 1 and not required for this lock.

Two layers

Layer	Owns	Does not own
Game ledger (MonetaryPlatform)	Play mint 51/49, convert → LUMENAR, fiat→BTUCOIN mint; convert→LUMENAR, Season Pass LUMENAR spend, AntiCheat withdraw gates	Block production, validator sets
PoS chain	Transferable BTUCOIN, bridge mint/burn, optional stake / unstake	Match outcomes, objective completion, LUMENAR storefront tender

Note

Authority. In-session balances that affect play or Marketplace are always the studio ledger until a completed deposit/withdraw settles. Clients never invent on-chain credit.

Fiat store → BTUCOIN (not LUMENAR)

When a player pays real money on the Marketplace, that SKU mints BTUCOIN with 51% BTU Games / 49% buyer. It does not grant LUMENAR. Shopping requires convert 49% → LUMENAR, then LUMENAR spend. PoS deposit/withdraw still only moves the player 49% ledger lane — fiat mint credits the studio ledger first; withdraw is optional later.

Note

Fiat. $ → BTUCOIN mint 51/49 on studio ledger. Spend = convert → LUMENAR. PoS bridge is not on the hot purchase path.

Withdraw (game → chain)

1. Player requests withdraw of some or all of their player 49% BTUCOIN on Marketplace Wallet.
2. Server checks: Online / EOS identity, sufficient balance, no active fraud / AntiCheat hold, amount ≥ min withdraw (TBD-038-A).
3. Ledger freezes then burns/debits that amount (fail-closed; studio 51% treasury never withdrawable).
4. Bridge releases / mints the same amount on-chain to the linked wallet after policy delay / confirmations (TBD-038-B).
5. If bridge fails after debit: compensated credit back to ledger or support queue — never silent loss. Spec the reconcile job at scaffold.

Note

Fail-closed withdraw. Reject when AntiCheat / economy fraud signals are elevated, when identity is not Online, when balance is insufficient, or when the bridge is paused. Hotkey / UI cannot bypass.

Deposit (chain → game)

1. Player sends on-chain BTUCOIN to the studio deposit address / contract (Wallet shows QR / address / connect flow — external wallet OK).
2. After N PoS confirmations (TBD-038-C), MonetaryPlatform credits the EOS PUID ledger.
3. Credited BTUCOIN is the player 49% lane for convert / future withdraw. It does not invent studio treasury share.
4. Deposit never grants LUMENAR, Credits, frames, or Season Pass tiers by itself — convert or spend rules unchanged.

Optional stake (on-chain only)

• Staking is optional and happens on the PoS layer (or a staking contract), not inside a match.
• Rewards = inflation / fee share / protocol rewards — never gun power, cadence, trees, RAID access, Ladder MMR, or Trust rank.
• Show stake / unstake / bonding period on Marketplace Wallet (or a Crypto sub-pane). Not Character I. Not OmniVisor combat chrome.
• Unstake delay (bonding) is expected PoS UX; copy must say when funds return to withdrawable on-chain balance, then deposit if they want ledger credit again.
• Validators may be studio-run, delegated, or host-chain native — product does not require every player to be a validator.

Note

Stake ≠ power. No Combat GE, no loadout gate, no Ladder boost from staking BTUCOIN.

Mint policy stays game-side

• Daily / weekly / hard objectives still mint on the studio ledger: fiat V (TBD-039), M = V / P at settlement, then FS-ECO-004 (51/49).
• PoS block rewards and stake rewards are not a substitute for play mints and do not skip the studio cut on play grants.
• Token inflation for stakers (if any) is a chain/tokenomics table (TBD-038-D) separate from play grant tables.

Wallet chrome

• Year 1 Wallet: LUMENAR, player BTUCOIN 49%, floor, market, settlement P, Convert at P.
• PoS hybrid adds: linked wallet status, deposit instructions, withdraw form, pending bridge jobs, optional stake summary.
• Connect-wallet / deep-link to an external wallet is allowed. Embedding a full validator or seed phrase UX in UE5 is not.

What this is not

• Not Proof of Work mining in the client.
• Not “play to validate blocks.”
• Not BTUCOIN as Marketplace tender (still convert → LUMENAR).
• Not a path to buy power, frames, or trees.
• Not required for Demo exit or Year‑1 Ladder vertical slice.

Owners

Owner	Owns
MonetaryPlatform	Ledger debit/credit, bridge job state, withdraw gates, AntiCheat hooks
TFAFrontend / Marketplace Wallet	Deposit / withdraw / stake presentation
TFAOnline	EOS identity bind; never Combat
Legal / ops (TBD-038)	Custody, listing, jurisdiction, host-chain choice

Exit gates (when PoS hybrid ships)

1. Year‑1 ledger play path still green with bridge disabled.
2. Withdraw debits only player 49%; studio 51% untouched.
3. Deposit credits ledger only after confirmations; client cannot fake credit.
4. Fraud / AntiCheat hold blocks withdraw.
5. Stake UI cannot grant Combat or Ladder advantage.
6. BTUCOIN still cannot buy storefront / listings without convert → LUMENAR.
