Modules

Overview

Planq utilizes Ethermint and the Tendermint Core consensus engine underneath. Specifically, the Cosmos SDK is a framework that facilitates the development of secure state-machines on top of Tendermint. In particular, we utilize different SDK modules to facilitate the special features of Planq.

In this documentation, we will be focusing on some of the important modules we used, for example:

  • Bank - Token transfer functionalities and query support for the total supply of all assets;

  • Distribution - Fee distribution, and staking rewards to the validators and delegator;

  • Governance - On-chain proposals and voting;

  • Mint - Creation of new units of staking token;

  • Slashing - Validator punishment mechanisms;

  • Staking - Proof-of-Stake layer for public blockchains;

bank

Introduction

The bank module maintains the state of two primary objects:

  • Account balances by address;

  • Total supply of tokens of the chain

bank module tracks and provides query support for the total supply of all assets used in the application. It also supports token transfer functionalities. Specifically, the total supply is updated whenever a token is:

  • Minted, e.g. Token created by the mint module; or

  • Burned, e.g. Token distorted by the slashing module.

bank module: Network Parameters and configuration

distribution

Introduction

The distribution module is responsible for the distribution of rewards to the validators and delegators.

Overview

Network Parameters

Below are all the network parameters for the distribution module:

  • community_tax - The rate of community tax;

  • base_proposer_reward - Base bonus on transaction fees collected in a valid block;

  • bonus_proposer_reward - Maximum bonus on transaction fees collected in a valid block;

  • withdraw_addr_enabled - Whether delegators can set a different address to withdraw their rewards.

Rewards

There are two main types of rewards

Block reward

Block rewards are distributed proportionally to all validators relative to their voting power. This means that even though each validator gains cro with each reward, all validators will maintain equal weight over time.

For the validator operator, the distribution information is updated if:

  • the amount of delegation to a validator is updated (delegation, unbond, slashing etc.);

  • a validator successfully proposes a block and receives the reward;

  • any delegator withdraws from a validator, or

  • the validator withdraws it's commission.

For delegators, once they have delegated to a validator, they will be entitled to a portion of the total reward obtained by the validators. The reward is proportional to their delegated amount, and the commission charged by the validator operator (if any).

Transaction Fees Bonus

When a validator is selected to propose the next block, they must include at least 66% precommits of the previous block. To incentivise validators to include more than 66% precommits, the module provide a bonus reward (portion of the transaction fee in the block) to the proposer.

This bonus reward is dependent linearly on the precommits from the other validators. Stating from 66% of the precommits, the basic bonus will be base_proposer_reward and increase linearly to bonus_proposer_reward when the validator includes 100% of the precommits.

This mechanism aims to incentivize non-empty block proposals, better networking between validators as well as to mitigate censorship. For further example, kindly refers to this link.

Community tax

The community_tax is the tax rate to the reward obtained by the validator. Specifically, part of the reward will be taxed and send to the community pool. The funds in the community pool can be withdrawn by submitting a community pool spend proposal with the gov module.

Even if the community_tax is set to be zero, the balance of the community pool could be non-zero. For example, the truncated remainder in some accounting edge cases will be sent to the community pool as well. Besides that, users can fund the community pool voluntary, and there could be funds allocated to the community pool in the genesis.

distribution module: Network Parameters and configuration

The following tables show overall effects on different configurations of the distribution related network parameters:

gov

Introduction

The gov module enables on-chain governance which allows Planq token holder to participate in the decision-making processes. For example, users can:

  • Form an idea and seek the feedback;

  • Create the proposal and adjust according to feedback as needed;

  • Submit a proposal along with an initial deposit;

  • Deposit tokens and fund an active proposal;

  • Vote for an active proposal.

The details about the governance proposal process are available on The Proposal Process page.

Overview

Network parameters

Below are all the network parameters for the gov module:

  • deposit_params - Deposit related parameters:

    • min_deposit: Minimum deposit for a proposal to enter voting period; and

    • max_deposit_period: Maximum period for Cro holders to deposit on a proposal.

  • voting_params - Voting related parameters

    • voting_period: The length of the voting period.

  • tally_params - Tally related parameters

    • quorum: The minimum percentage of voting power that needs to be casted on a proposal for the result to be valid;

    • threshold: Minimum proportion of Yes votes (excluding Abstain votes) for the proposal to be accepted; and

    • veto: Minimum proportion of Veto votes to total votes ratio for proposal to be vetoed.

The Governance Procedure

Phase 0 - Submit a proposal along with an initial deposit:

Users can submit a proposal with an initial deposit. The proposal will then become "active" and entre the deposit period.

Phase 1 - Deposit period

During the deposit period, users can deposit and support an active proposal. Once the deposit of the proposal reached min_deposit, it will enter the voting period. Otherwise, if the proposal is not successfully funded within max_deposit_period, It will become inactive and all the deposit will be refunded.

Phase 2 - Voting period

During the voting period, staked (bonded) token will be able to participate in the voting. Users can choose one of the following option: "yes", "no", "no_with_veto" and "abstain"

After the voting_period has passed, there are several scenarios that a proposal will consider to be "Rejected", for example, if

  • No one votes (everyone "abstain");

  • Votes did not reach the quorum;

  • More than veto of voters vote for "no_with_veto";

  • More than threshold that non-abstaining voters vote "no".

Otherwise, the proposal will be accepted and changes will be implemented according to the proposal.

gov module: Network Parameters and configuration

The following tables show overall effects on different configurations of the gov related network parameters:

mint

Introduction

The mint module is responsible for creating token in a flexible way to reward the validator who participate in the proof of stake consensus process (see also the distribution module). It is also designed in a way to bring a balance between market liquidity and staked supply.

Overview

Network parameters

Below are all the network parameters for the mint module:

  • "blocks_per_year" - The expected number of blocks being produced per year;

  • "goal_bonded" - Goal of bonded token in percentage;

  • "inflation_max" - Maximum annual inflation rate;

  • "inflation_min" - Minimum annual inflation rate;

  • "inflation_rate_change" - Maximum annual change in inflation rate;

  • "mint_denom" - Token type being minted.

The target annual inflation rate is recalculated for each previsions cycle. The inflation is also subject to a rate change (positive or negative) depending on the distance from the desired ratio ("goal_bonded"). The maximum rate change possible is defined to be "inflation_rate_change" per year, where the annual inflation is capped as between "inflation_min" and "inflation_max".

mint module: Queries

Queries

query mint params - Query the current minting annual provisions value

We can query the current minting annual provisions value, for example:

  $ planqd query mint annual-provisions

implies that the current minting annual provisions will be 109573801550200370 atplanq ( i.e. 1,095,738,015 cro)

query mint inflation - Query the current minting inflation value

We can query the current minting inflation value, for example:

  $ planqd query mint inflation
  0.013687008526984104

implies that the current minting annual provisions will be 0.013687008526984104( i.e. 1.368%)

query mint annual-provisions - Query the current minting parameters

We can query the current query parameters by

Appendix

gov module: Network Parameters and configuration

The following tables show overall effects on different configurations of the mint related network parameters:

slashing

Introduction

Validators are responsible for signing or proposing block at each consensus round. A penalty should be imposed on validators' misbehavior to reinforce this.

Specifically, slashing functionality that aims to dis-incentivize network-observable actions, such as faulty validations. The penalties may include losing some amount of their stake, losing their ability to perform the network functionality for a period of time, collect rewards etc.

Overview

Network parameters

Below are all the network parameters used to configure the behavior of validator punishments. Details of all these parameters and their effect on behavior of validator punishments is discussed later in this document.

  • signed_blocks_window: Number of blocks for which the liveness is calculated for uptime tracking;

  • min_signed_per_window: Maximum percentage of blocks with faulty/missed validations allowed for an account in last; signed_blocks_window blocks before it gets deactivated;

  • downtime_jail_duration: Duration for jailing;

  • slash_fraction_double_sign: Percentage of funds being slashed when validator makes a byzantine fault; and

  • slash_fraction_downtime: Percentage of funds being slashed when a validator is non-live.

Slashing mechanism

Punishments for a validator are triggered when they either make a byzantine fault or become non-live:

  • Liveness Faults (Low availability)

    A validator is said to be non-live when they fail to sign at least min_signed_per_window blocks (in percentage) in the last signed_blocks_window blocks successfully. signed_blocks_window and min_signed_per_window are network parameters and can be configured during genesis and can be updated during runtime by the governance module.

:::tip Example: For example, if block_signing_window is 2000 blocks and min_signed_per_window is 0.5, a validator will be marked as non-live and jailed if they fail to successfully sign at least 2000*0.5=1000 blocks in last 2000 blocks. :::

  • Byzantine Faults

    A validator is said to make a byzantine fault when they sign conflicting messages/blocks at the same height and round. Tendermint has mechanisms to publish evidence of validators that signed conflicting votes so they can be punished by the slashing module. For example:

    • Validator who votes for two different blocks within a single round ("Equivocation validator"/ "Double signing");

    • Validator who signs commit messages for arbitrary application state ( "Lunatic validator").

Remark: The evidence of a set of validators attempting to mislead a light client can also be detected and captured. However, even the Amnesia attack can be detected, punishment can not be applied at this stage, as we can not deduce the malicious validators.

:::tip Implementation note: Tendermint passes Evidence of a byzantine validator in BeginBlock request. Before jailing any account due to byzantine fault, that evidence should be verified. Also, it should be checked that evidence provided by tendermint is not older than max_age in tendermint. :::

Inactivity Slashing

It is important that the validators maintain excellent availability and network connectivity to perform their tasks. A penalty should be imposed on validators' misbehavior to reinforce this.

When a validator fails to successfully sign missed_block_threshold blocks in last block_signing_window blocks, it is immediately jailed and punished by deducting funds from their bonded and unbonded amount and removing them from active validator set. The funds to be deducted are calculated based on slash_fraction_downtime. Kindly refer to this link on the logic of the liveness tracking.

Jailing

A validator is jailed when they make liveness or Byzantine fault, when a validator is jailed, it will no longer be considered as an active validator until they are un-jailed. Futhermore, it cannot be un-jailed before downtime_jail_duration. This downtime_jail_duration is a network parameter which can be configured during genesis.

:::warning Important: When a validator is jailed because of a byzantine fault, their validator public key is added to a list of permanently banned validators and cannot re-join the network as a validator with the same public key, see staking tombstone :::

Un-jailing

When a jailed validator wishes to resume normal operations (after downtime_jail_duration has passed), they can create anunjail transaction which marks them as un-jailed. Validator will then rejoin the validator set once it has bee successful un-jailed.

Slashing for Byzantine Fault

When there is byzantine fault detected, they are immediately slashed other than jailed. The funds to be deducted are calculated based on slash_fraction_double_sign. Furthermore, validator who commit this double-signing fault will also be put into the "tombstone state", which means it will be blacklisted and jailed forever.

tx slashing unjail - Unjailing a validator

Validator could be punished and jailed due to network misbehaviour, for example if we check the validator set:

................................

After the jailing period has passed, one can broadcast a unjail transaction to unjail the validator and resume its normal operations by

$ planqd tx slashing unjail --from node1 --chain-id planq_7070-2

slashing module: Network Parameters and configuration

The following tables show overall effects on different configurations of the slashing related network parameters:

staking

Introduction

The staking module handles Proof-of-Stake related logics, which plays a very import part to the underneath consensus protocol.

Overview

Planq is based on Tendermint Core's consensus engine, it relies on a set of validators to participate in the proof of stake (PoS) consensus protocol, and they are responsible for committing new blocks in the blockchain.

  • unbonding_time: The time duration of unbonding;

  • max_validators: The maximum number of validator;

  • max_entries: The max entries for either unbonding delegation or redelegation;

  • historical_entries: The number of historical entries to persist; and

  • bond_denom: Coin denomination for staking.

Validator

Validators are responsible for signing or proposing block at each consensus round. It is important that the validators maintain excellent availability and network connectivity to perform their tasks. To incentivise the validator nodes to run the network, rewards are distributed to the validators according to their performance and amount of staked token (see distribution and mint). On the other hand, a penalty should be imposed on validators' misbehavior (see slashing).

Delegator

The staking module enables PLQ owners to delegate their tokens to active validators and share part of the reward obtained by the validator during the proof of stake protocol(see distribution module). Specifically, It allows token owners to take part in the consensus process without running a validator themselves.

It is important to point out that the delegator and the validator are on the same boat: They share the reward and the risk. In particular, part of their delegated token could be slashed due to validator's misbehaviour (see slashing). Therefore, It is very important to choose a reliable validator to delegate. Kindly refer to this link for detailed specification and state transitions of delegation.
