### Understanding Configuration Values

Low level blockchain constants

### Intro

These values underpin the behavior of the entire blockchain. In a sense, each witness votes for these configuration values every time they sign a block. Unlike many of the Dynamic Global Properties, these values never change at runtime (e.g., as a witness, in order to change them, you typically must shut down your node, make the change, recompile, and run).

See: config.hpp

Usually, these configuration values are universally adhered to, but there are situations where these values can and should be altered, like in the case of deploying a new blockchain (typically a testnet). Some of the values that do not affect consensus, like `STEEM_SOFT_MAX_COMMENT_DEPTH`, are allowed to change to some extent.

### `HIVE_ADDRESS_PREFIX`

- Related

Address prefix used on mainnet is `STM` and on testnet is `TST`.

- Examples:

  - `STM` - mainnet

  - `TST` - mainnet

See: Hive Testnet

### `HIVE_BLOCKS_PER_HOUR`

- Related

`60*60/HIVE_BLOCK_INTERVAL`

### `HIVE_BLOCK_INTERVAL`

- Related

Block interval in seconds is `3`. This is the target for block production. This constant is also used as a component for determining valid peer inventory, bandwidth calculations, and block production gaps.

### `HIVE_CASHOUT_WINDOW_SECONDS`

- Related

This value was simply set to 7 days, since HF17.

Prior to this, other very complicated machinations were tried like multiple payouts and an initial 24 hours (prior to HF12) and even initial 12 hours (in HF12) all with time extensions depending on how much of an upvote the content got.

Note, on testnet, this is typically much shorter: 1 hour.

- Examples:

  - `604800` - mainnet

  - `3600` - testnet

See: Hive Testnet

### `HIVE_CHAIN_ID`

- Related

The chain ID to connect to, which is used to seed signing and prevent transaction crosstalk between two chains, typically mainnet and testnet.

- Examples:

  - `0000000000000000000000000000000000000000000000000000000000000000` - mainnet

  - `18dcf0a285365fc58b71f18b3d3fec954aa0c141c44e4e5cb4cf777b9eab274e` - testnet

See: Hive Testnet

### `HIVE_CHAIN_ID_NAME`

- Related

Tyically used to automatically get a unique chain id for a testnet.

See: Hive Testnet

### `HIVE_CONVERSION_DELAY`

- Related

Prior to HF16, 7 day conversion. After HF16 3.5 day conversion

See: #551

### `HIVE_CREATE_ACCOUNT_DELEGATION_RATIO`

- Related

This ratio is set to 5 and is used to determine the cost of an account created with delegation.

As an example, imagine the account creation fee is currently `3.000 HIVE`. Instead of creating the account using pure HIVE, there is an option to use delegation so that the blockchain would reduce the creation fee to `0.100 HIVE`. Going this route would require a delegation of `15.000 HIVE`, that can be revoked at any time, but will stay in limbo for 30 days after the creation date (`HIVE_CREATE_ACCOUNT_DELEGATION_TIME`).

This minimum HIVE ensures that those accounts can transact if the delegation is removed.

See: #818

### `HIVE_CREATE_ACCOUNT_DELEGATION_TIME`

- Related

There is a minimum delegation period (30 days) and a minimum fee in HIVE even when delegating for account creation (derived with `HIVE_CREATE_ACCOUNT_DELEGATION_RATIO`). The minimum period enforces a rate limit on account creation.

Note that delegation can be revoked before 30 days have elapsed from the creation date, but stays in limbo.

See: #818

### `HIVE_DB_FORMAT_VERSION`

- Since: Mysterious Future
- Related

Version format string for platform independent state files. The Hive binary will refuse to load a state file where this does not match the built-in version.

- `db_format_version` - Must match HIVE_DB_FORMAT_VERSION
- `network_type` - Must match HIVE_NETWORK_TYPE
- `chain_id` - Must match requested chain ID and value of embedded GPO

See: #3084, `HIVE_NETWORK_TYPE`, state-format, from-state, to-state

See: https://steemd.com/b/1

### `HIVE_HARDFORK_REQUIRED_WITNESSES`

- Related

The minimum number of Delegated Proof of Stake witnesses required for hardfork. This guarantees 75% participation on all subsequent rounds.

By default it is set to 17, but when running a testnet, we can change it to 1 so that only one node instance would be sufficient and the network will be still functional and fast.

See: Hive Testnet

### `HIVE_INFLATION_NARROWING_PERIOD`

- Related

Inflation narrows 0.01% every 250k blocks, since HF16. At block 7,000,000, there was a 9.5% instantaneous inflation rate, decreasing to 0.95% at this rate of 0.01% every 250k blocks. This narrowing will take approximately 20.5 years and will complete on block 220,750,000.

Every round of block production begins with the shuffling of 21 witnesses: the top 20 witnesses (by vote), plus one randomly-selected standby witness. Each is given a turn to produce a single block at a fixed rate of one block every 3 seconds. If a witness does not produce a block in their time slot, then that time slot is skipped, and the next witness produces the next block.

In HF21, the reverse action is being reduced to 5 minutes.

See: `reverse_auction_seconds`, #1874, #1878

### `HIVE_SAVINGS_WITHDRAW_TIME`

- Related

- Related

Renamed from `HIVE_VOTE_REGENERATION_SECONDS`
