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 HIVE_SOFT_MAX_COMMENT_DEPTH, are allowed to change to some extent.

Sections

HBD_SYMBOL

Debt asset symbol, expressed as nai.



HIVE_ADDRESS_PREFIX

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

See: Hive Testnet



HIVE_BLOCKS_PER_HOUR

60*60/HIVE_BLOCK_INTERVAL



HIVE_BLOCK_INTERVAL

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

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.

See: Hive Testnet



HIVE_CHAIN_ID

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

See: Hive Testnet



HIVE_CHAIN_ID_NAME

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

See: Hive Testnet



HIVE_CONVERSION_DELAY

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

See: #551



HIVE_CREATE_ACCOUNT_DELEGATION_RATIO

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

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

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.

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



HIVE_DEFAULT_ACCOUNT_SUBSIDY_BUDGET

Default rate is 0.5 accounts per block



HIVE_DEFAULT_ACCOUNT_SUBSIDY_DECAY

347321 corresponds to a 5-day halflife



HIVE_DEFAULT_HBD_INTEREST_RATE

< 10% APR



HIVE_FEED_HISTORY_WINDOW

Price feed history window, which is 3.5 days since HF16.



HIVE_GENESIS_TIME

Scheduled time that the blockchain waited until the first block was produced. It is represented as the unix epoch of 1458835200, which is Thu Mar 24 16:00:00 UTC 2016. About five seconds later, the first block was produced.

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



HIVE_HARDFORK_REQUIRED_WITNESSES

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

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.

HIVE_MAX_WITNESSES

This value is set to 21, which means there are 21 witnesses cycling to produce blocks.

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.

HIVE_MINER_ACCOUNT

Represents the current witnesses



HIVE_MIN_ACCOUNT_NAME_LENGTH

See: #3084, HIVE_DB_FORMAT_VERSION, state-format, from-state, to-state



HIVE_NULL_ACCOUNT

The blockchain checks all asset types transferred to this account, thus, even reward balances and VESTS are burned.

See: operation_time_tests.cpp



HIVE_NULL_ACCOUNT

Represents the canonical account with NO authority (nobody can access funds in null account)



HIVE_PROPOSAL_MAINTENANCE_CLEANUP

1 day

See: PR#3272, PR#3278, Decentralized Hive Fund, database_api.get_reward_funds, sps_fund

HIVE_REVERSE_AUCTION_WINDOW_SECONDS

Removed in HF21, see: #1874

Prior to HF6, there was no reverse auction logic. From HF6 to HF19, the reverse auction window is 30 minutes.

In HF20, the reverse action is being reduced to 15 minutes.

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

See: reverse_auction_seconds, #1874, #1878



HIVE_ROOT_POST_PARENT

Represents the canonical root post parent account



HIVE_SAVINGS_WITHDRAW_TIME

This value sets the timelock of 3 days for funds being withdrawn from savings. Funds can be transferred into savings instantly, but require 72 hours (3 days) to withdraw from savings. This will guarantee there is at least 1 business day during which you can contact your recovery agent.



HIVE_SOFT_MAX_BLOCK_SIZE

Max block size cannot be more than 2MiB (2*1024*1024).

See: #1655



HIVE_SOFT_MAX_COMMENT_DEPTH

A comment is nested at a maximum depth of 255. As a soft limit, it is enforced by the witness_plugin.

Prior to HF17, the maximum comment depth was 6.

See: #767, HIVE_MAX_COMMENT_DEPTH, witness_plugin.cpp

HIVE_UPVOTE_LOCKOUT_HF17

Accounts may not increase payout within last 12 hours before payout, since HF17.



HIVE_VESTING_WITHDRAW_INTERVALS

Sets the power-down rate, which is fulfilled once a week over 13 weeks.

Prior to HF16, this value was 104 weeks.

See: #551



HIVE_VESTING_WITHDRAW_INTERVAL_SECONDS

1 week per interval



HIVE_VOTE_DUST_THRESHOLD

Used to determine when abs_rshares is too small while evaluating vote operation.

See: #774, vote, vote2



HIVE_VOTING_MANA_REGENERATION_SECONDS

Renamed from HIVE_VOTE_REGENERATION_SECONDS



HIVE_WITNESS_SUBSIDY_DECAY_PERCENT

Since witness decay only procs once per round, multiplying the decay constant by the number of witnesses means the per-witness pools have the same effective decay rate in real-time terms.



IS_TEST_NET

Indicates if this node is running on testnet.

See: Hive Testnet



NEW_HIVE_TREASURY_ACCOUNT

See: OBSOLETE_TREASURY_ACCOUNT



OBSOLETE_TREASURY_ACCOUNT

See: Hive Testnet
