# Genesis and params

Genesis bootstraps chain state, internal contracts, and initial balances.

## Genesis block creation

`genesis_block` performs:

* State initialization and internal contract setup.
* Funding of configured genesis accounts (including dev/test keys when used).
* Genesis treasury account creation and shielded pool seeding.
* Emission of genesis transactions (create2 factory, optional shielded key).
* Construction of the genesis header with initial difficulty and gas limit.

## Explicit genesis issuance logic

Current native genesis target is 3,900,000,000 MAZZE.

In code, genesis accounting is two-step:

1. Credit explicit genesis accounts first.
2. Mint only the remaining amount needed to reach the configured genesis total.

This avoids double-counting between explicit allocations and the special genesis-account mint path.

Shielded pool bootstrap at genesis is a treasury transfer, not extra issuance. See `../tokenomics/shielded-pool-genesis-fund.md`.

## Genesis inputs

* `genesis_accounts` and `genesis_secrets` can override the account set.
* `execute_genesis` controls whether genesis is executed or loaded from db.

## Chain parameters

Configuration exposes key consensus parameters:

* `initial_difficulty`
* `era_epoch_count`
* `referee_bound`
* `adaptive_weight_beta`, `heavy_block_difficulty_ratio`
* `timer_chain_block_difficulty_ratio`, `timer_chain_beta`
* `transaction_epoch_bound`

Hardfork transitions are also configured by height/epoch.
