DigiByte-II Core

DigiByte-II Core is a standalone UTXO blockchain client (node, wallet, and optional Qt GUI).

This repository is configured as a new chain launch profile with its own genesis block and network identity. It is code-derived from DigiByte software, but runtime consensus/docs below describe the DigiByte-II network configuration.

Chain Identity

• Name: DigiByte-II
• Ticker: DGB2
• PoW algorithm: SHA256D (single-algo)
• Default Bech32 HRP (mainnet): dgb2
• Genesis message:
  • Decentralized in an age of centralized conflict and constrained energy.

Genesis and Launch Profile

Mainnet genesis

• Hash: 00000581951e9da3f12d75651f2301cc2e506ebd3095bfc26a6732ba1b20db36
• Merkle root: d7885a1114aa804f13aff5a65f7fc0eb03eeaeed13fe172bf499ecedc7a2dcc1
• Time: 1389388394
• Bits: 0x1e0ffff0
• Nonce: 1894492

Consensus activation from launch

Mainnet is configured so modern script/algo rules are not waiting on legacy historical heights:

• BIP34/BIP65/BIP66: height 1
• CSV: height 1
• SegWit: always active (SegwitHeight = 0)
• Mining algorithm: SHA256-only (IsAlgoActive() allows only ALGO_SHA256D)

Chain Economics (Mainnet)

Values in this section are taken from consensus code (src/validation.h, src/validation.cpp, src/consensus/amount.h, src/kernel/chainparams.cpp).

Core monetary/time constants

• Block target time: 60 seconds (BLOCK_TIME_SECONDS)
• Blocks per minute: 1
• Blocks per hour: 60
• Blocks per day: 1,440
• Blocks per year (365d): 525,600
• Max supply bound (consensus money range): 21,000,000,000 DGB2 (MAX_MONEY)
• Smallest unit: 1 DGB2 = 100,000,000 base units (COIN)

Block reward schedule

• Genesis block reward parameter: 8000 (genesis coinbase is unspendable)
• First mined block subsidy (height 1): 72,000 DGB2

Height range	Subsidy rule
0 - 1,439	72,000 DGB2 fixed
1,440 - 5,759	16,000 DGB2 fixed
5,760 - 67,199	8,000 DGB2 fixed
67,200 - 399,999	Starts at 8,000 DGB2, reduced by 0.5% every 10,080 blocks
400,000 - 1,429,999	Starts at 2,459 DGB2, reduced by 1% every 80,160 blocks
>= 1,430,000	Starts at 1,078.5 DGB2, monthly decay factor 0.98884

Note: Subsidy is clamped to 0 when it drops below 1 DGB2 in consensus logic.

Network Ports

Network	P2P	RPC	Tor
Mainnet	22024	24022	24122
Testnet	22026	24023	24123
Signet	48443	29443	29445

DNS Seed Servers

Canonical DNS seeds are configured in chain params and should be kept in sync with runtime values.

Mainnet

• seed01.dgb2.org
• seed02.dgb2.org

Testnet

• seed01-testnet.dgb2.org
• seed02-testnet.dgb2.org

Signet / Regtest

• No default DNS seed servers are configured.

Address Prefixes

Address validation constants

Canonical constants from chain params (ADDRESS_HRP, P2PKH_PREFIX, P2SH_PREFIX):

Network	ADDRESS_HRP	P2PKH_PREFIX	P2SH_PREFIX
Mainnet	dgb2	0x1E	0x3F
Testnet	dgb2t	0x7E	0x8C
Signet	dgb2t	0x7E	0x8C
Regtest	dgb2rt	0x7E	0x8C

SegWit (Bech32 HRP)

Network	Prefix
Mainnet	dgb2
Testnet	dgb2t
Signet	dgb2t
Regtest	dgb2rt

Mining Algorithm

• Active PoW algorithm: SHA256D only
• Multi-algo paths are disabled by consensus selection (single-algo chain)

Build

The master branch is regularly built and tested, but is not guaranteed to be production-stable at all times.
