Recorded and assembled networks

A network with history cannot have its genesis changed: the bytes are its identity — every blockchain ID, the staker set, and the units every balance since block 0 is denominated in. So mainnet and testnet are recorded: genesis.json is the document in their luxd-genesis ConfigMap, and GetGenesis returns it byte for byte. A node started without --genesis-file joins the running network — C-Chain 2Hx3UMuW… with block 0 0x3f4fa2a0… on mainnet, 5kjSQWfw… with block 0 0x1c5fe377… on testnet. Both are 9-decimal by birth, and allocations handed to them are refused.

devnet, localnet and new networks are assembled from network.json, pchain.json and one shard per chain, in 6-decimal units. A shard present is a chain in genesis; a shard absent is not.

Mainnet C-Chain Genesis

The mainnet C-Chain was initialized with a single genesis allocation:

Address	Balance
`0x9011e888251ab053b7bd1cdb598db4f9ded94714`	2,000,000,000,000,000,000,000,000,000,000 wei (2T LUX)

Key Parameters

Chain ID: 96369
Gas Limit: 12,000,000 (0xB71B00)
Min Base Fee: 25 gwei
Block Rate: 2 seconds

Network IDs

Network	Chain ID	Network ID	Purpose
LUX Mainnet	96369	1	Production network
LUX Testnet	96368	2	Public test network
LUX Devnet	96367	3	Fast iteration dev network

Usage

These genesis files are used by:

luxd node for network initialization
coreth for C-Chain configuration
Block explorers for genesis block verification
Migration tools for state reconstruction

RPC Endpoints

/v1 is luxd's only HTTP prefix (node/server/http/server.go, baseURL). The port differs per fleet — read spec.ports.http off that net's LuxNetwork CR, never assume one:

Mainnet: http://localhost:9630/v1/chain/c/rpc
Testnet: http://localhost:9640/v1/chain/c/rpc
Devnet: http://localhost:9650/v1/chain/c/rpc

Genesis Account

All networks use the same production genesis account:

Account	Balance	Networks
`0x9011e888251ab053b7bd1cdb598db4f9ded94714`	2T LUX	All networks

State Data & RLP Exports

Blockchain state exports and RLP-encoded blocks are maintained in a separate repository:
