View History

Essential steps to get Nas from Nxt 1.1.3

"Essential" here means that they are the only required modifications for the Nas blockchain. The non-essential modifications doesn't affect the blockchain.

1. Blockchain identity and coin distribution

  • src/java/nxt/Genesis.java: taken from Nas 0.8.13(N1), changing interface for final class. This file is the essence of the coin.
  • html/ui/js/nrs.server.js: genesis account ID hardcoded!, changed to NAS-*

2. Start of blockchain time, 2014-March-25 12:00:0.000

  • src/java/nxt/Constants.java: EPOCH_BEGINNING
  • html/nrs/myTransactions.java
  • html/nrs/orphanedBlocks.java
  • html/nrs/recentBlocks.java
  • html/nrs/unconfirmedTransactions.java
  • html/ui/js/nrs.messages.js
  • html/ui/js/nrs.polls.js
  • html/ui/js/nrs.util.js
  • html/ui/message.html

3. Total amount of coins 10 billion NAS

  • src/java/nxt/Constants.java: defined at MAX_BALANCE_NXT.
  • src/java/nxt/DbVersion.java: method update, cases 1, 3, 24 and 26, BIGINT in DB fields block.total_amount and transaction.amount.
  • src/java/nxt/BlockImpl.java: getBytes(), two conditions version < 3
  • src/java/nxt/TransactionImpl.java: getBytes() and signatureOffset(), two conditions useNQT() in case of false

Non-essential steps in order to complete the identity of Nas Coin

Name properties, and filename

  • ./* recursively: replace of Property("nxt. with Property("nas.
  • nxt-default.properties renamed to nas-default.properties
  • src/java/nxt/Nxt.java: properties filename in strings
  • nas-default.properties:
    • replaced nxt. for nas.
    • updated values (mainly timeouts) to that of Nxt recent version, 1.4.17

Ports for Nas servers

  • conf/nas-default.properties: defaults for peer (7871), UI (7872), API(7873):
  • src/java/nxt/peer/Peers.java: peer default (7871) and testnet (6871)
  • src/java/nxt/user/Users.java: UI testnet (6872)
  • src/java/nxt/http/API.java: API testnet (6873)
  • html/ui/js/nrs.js: API testnet (6873, hardcoded!)

Block heights for check points

  • src/java/nxt/Constants.java: NQT_BLOCK = 35025 and other *_BLOCK, (taken from decompiling the .jar file in Nas Client 1.1.3(N1))
  • src/java/nxt/BlockchainProcessorImpl.java: CHECKSUM_*, taken from the log when running with null values from scratch enough time to pass that heights

Hardcoded peer nodes

  • src/java/nxt/peer/DbVersion.java: as it must be hardcoded in this file, we use the 3 currently trusted
  • conf/nas-default.properties: empty wellKnownPeers, knownBlacklistedPeers and testnetPeers, as any peer should go to conf/nas.properties

Prefix NAS- for account ID:

  • src/java/nxt/util/Convert.java
  • html/ui/js/assetexchange.js
  • html/ui/js/contacts.js
  • html/ui/js/nrs.forms.js
  • html/ui/js/nrs.server.js
