🚀 Highlights

1. Founder / Dev Reward (10%)

A fixed founder reward has been added at the consensus level:

• From each block:
  • Miner receives:
    • 90% of the block subsidy
    • 100% of the transaction fees
  • Dev wallet receives:
    • 10% of the block subsidy
• The logic guarantees:
  • minerAmount + devReward == totalReward
  • No consensus violation: total block reward is preserved.
• If the dev address is invalid for any reason, 100% of the reward goes to the miner as a fallback.

This ensures ongoing funding for development while keeping miners properly incentivized.

2. Default Seed Node

A public seed node has been hardcoded into the network parameters to improve initial connectivity for new nodes and wallets:

• Seed node: 75.86.96.101
• Default mainnet port: 17554

New nodes can now discover peers without requiring manual addnode entries in flashcoin.conf.

3. Coinbase Reward Structure Cleanup

The coinbase transaction logic has been updated to cleanly separate:

• blockReward → block subsidy
• fees → transaction fees
• totalReward = blockReward + fees

On top of this:

• The founder reward is calculated as 10% of the subsidy only.
• The miner output is adjusted accordingly.
• A second output is added for the dev wallet with the computed founder reward.

If anything goes wrong with the dev destination (invalid address, etc.), the miner receives the full totalReward.

  • GUI “About” dialog in FlashCoin Core
