BSV, bitcoin.conf

I’d be happy to explain each part of your Bitcoin configuration file in detail. Let’s break down the bitcoin.conf file line by line:

server=1

• This enables the Bitcoin node to operate as a server. When set to 1, it allows the node to accept JSON-RPC commands, which is necessary if you want to interact with your node programmatically or through a wallet interface.

rpcuser=hajunho
rpcpassword=********

• These lines configure the credentials for Remote Procedure Call (RPC) authentication:
  • rpcuser: Sets the username for RPC connections to “hajunho”
  • rpcpassword: Sets the password (hidden for security) that will be required when connecting to the Bitcoin node via RPC
• These credentials protect your node from unauthorized access when the RPC interface is enabled

txindex=1

• This enables full transaction indexing. With this option enabled, your node will maintain an index of all transactions in the blockchain, not just those relevant to your wallet.
• This allows you to look up any transaction by its ID (txid) and is essential for certain applications or if you want to run block explorers or other services that need complete transaction data.

# 필수 합의 매개변수 (Essential Consensus Parameters)

• This is a comment indicating that the following parameters are related to consensus rules

excessiveblocksize=2000000000

• Sets the maximum block size your node will accept to 2GB (2 billion bytes)
• This is quite large compared to Bitcoin Core’s typical 1MB limit, suggesting this might be a Bitcoin Cash or Bitcoin SV configuration, or a modified Bitcoin node that supports bigger blocks

maxstackmemoryusageconsensus=100000000

• This sets the maximum memory that can be used by the script interpreter for the stack to 100MB
• It helps prevent denial-of-service attacks by limiting resources scripts can consume during validation

# 필수 정책 매개변수 (Essential Policy Parameters)

• Comment indicating the following parameters are related to node policy rather than consensus rules

minminingtxfee=0.00000500

• Sets the minimum fee rate (in BTC per kilobyte) that the node will accept for transactions to be included in blocks it mines
• The value 0.00000500 BTC/KB (or 0.5 satoshis per byte) is relatively low, allowing for less expensive transactions to be mined

This configuration appears to be for a Bitcoin node fork that supports large blocks (like Bitcoin Cash or Bitcoin SV) since the excessive block size is set to 2GB. The configuration enables the node to function as a server with RPC capabilities, full transaction indexing, and specific consensus and policy parameters to control how the node interacts with the network.
