I have made certain changes in LedgerManagerImpl.cpp file under src-> ledger folder on line approx 68-72

  const uint32_t LedgerManager::GENESIS_LEDGER_BASE_FEE = 50;
  const uint32_t LedgerManager::GENESIS_LEDGER_BASE_RESERVE = 0;
  const uint32_t LedgerManager::GENESIS_LEDGER_MAX_TX_SIZE = 100;
  const int64_t LedgerManager::GENESIS_LEDGER_TOTAL_COINS = 10000000;

My aim is to change the base fee to 50, base reserve to 0 and total coins to 10000000.

Although we can change the transaction fees to 1 stroop using var txn = new Stellar.TransactionBuilder(sourceAccount, opts={fee:1}) But i want to make changes in the stellar core file. i want to change the base reserve too. I asked this question to other platform too but didnt get the correct answer.

I simply made the changes to the cpp files but as i have reinstalled the stellar core and tried running my programme but still didnt see any changes.

Any help will really be appreciated. I have made a private stellar with 2 nodes.

  • Values are stored in the ledger, take a look at your latest ledger if they were applied correctly: https://[yourHorizon]/ledgers/?order=desc&limit=1

  • @sui using the above commands giving me the below output "total_coins": "100000000000.0000000", "fee_pool": "0.0000918", "base_fee_in_stroops": 1, "base_reserve_in_stroops": 1, It is still not the value which i have set in LedgerManagerImpl.cpp file under src-> ledger folder . Help me out in unistalling the stellar core.

  • From my understanding those constants are start values when initializing a new network. So I guess if you start over with new-db it will probably init the new ledger with those values. Changes can somehow be set with the upgrades command (your question some days ago) but I have not done that before and have absolutely no experience regarding this.
