Rincoin-Sim v1.0.6: Customized Halving & MWEB Proof of Concept

🔬 Rincoin-Sim v1.0.6: Customized Halving & MWEB Proof of Concept

This release provides a dedicated simulation environment to validate
Rincoin's core protocol upgrades under accelerated regtest conditions,
prior to mainnet deployment.

✨ What's Validated

1. Customized Halving (Scenario II)

The multi-phase emission schedule has been fully verified via
Boundary Value Analysis (BVA) at 1/1000 scaled block heights.

Block (sim)	Block (mainnet)	RIN	Result
839 → 840	839,000 → 840,000	6.25 → 4.00	✅ CH Activated
2,099 → 2,100	2,099,000 → 2,100,000	4.00 → 2.00	✅ CH Halving 1
4,199 → 4,200	4,199,000 → 4,200,000	2.00 → 1.00	✅ CH Halving 2
6,299 → 6,300	6,299,000 → 6,300,000	1.00 → 0.60	✅ Terminal

2. MWEB (MimbleWimble Extension Block)

A critical consensus bug affecting MWEB initial activation has been
identified and fixed. The bug caused bad-txns-vin-empty errors on
the first HogEx transaction, preventing MWEB from functioning.

Fixed files:

• src/consensus/tx_check.cpp: HogEx transactions now correctly exempt
  from empty-vin validation
• src/mweb/mweb_miner.cpp: Defensive guard prevents empty HogEx
  transactions from being added to blocks

Validated:

• ✅ MWEB address generation (rrmweb1...)
• ✅ Transparent → MWEB Peg-in (10 RIN transferred)
• ✅ Automatic MWEB change address generation

3. Built-in Safety (Killswitch)

Both Mainnet and Testnet are physically disabled at the code level
(src/chainparams.cpp → SelectParams()). Accidental execution
outside of regtest is impossible.

Network	Status
./rincoind -regtest	✅ Allowed
./rincoind -testnet	❌ Error & exit
./rincoind	❌ Error & exit

⚠️ Important Notice

This is a simulation environment only.
Do NOT use this binary to connect to the Rincoin mainnet.
The 1/1000 scaled parameters will cause immediate consensus
rejection by standard nodes.

The production-ready Rincoin Core v1.0.6 mainnet release
will follow after community validation of this simulation.
