Use this glossary to learn about terms specific to the XPLA Chain.

Active Set

The top 40 validators that participate in consensus, receive rewards, and secure the blockchain.


An unchangeable ledger of transactions copied among a network of independent computer systems.


Groups of information stored on a blockchain. Each block contains transactions that are grouped, verified, and signed by validators.

Bonded validator

A validator in the active set participating in consensus. Bonded validators earn rewards.


When a user delegates or bonds XPLA to a validator to receive staking rewards. Validators never have ownership of a delegator’s XPLA, even when bonded. Delegating, bonding, and staking generally refer to the same process.


The percentage of staking rewards a validator keeps before distributing the rest of the rewards to delegators. Commission is a validator’s income. Validators set their own commission rates.

Community Pool

A special fund designated for funding community projects. Any community member can create a governance proposal to spend the tokens in the community pool. If the proposal passes, the funds are spent as specified in the proposal.


A system used by validators to agree that each block of transactions in a blockchain is correct. The XPLA Chain uses the Tendermint consensus. Validators earn rewards for participating in consensus. Visit the Tendermint official documentation site for more information.


The open-source framework the XPLA Chain is built on. For more information, check out the Cosmos SDK Documentation.


An application built on a decentralized platform.


Distributed denial of service attack. When an attacker floods a network with traffic or requests in order to disrupt service.


Decentralized finance. A movement away from traditional finance and toward systems that do not require financial intermediaries.


When users or delegators add their XPLA to a validator’s stake in exchange for rewards. Delegated XPLA is bonded to a validator. Validators never have ownership of a delegator’s XPLA. Delegating, bonding, and staking generally refer to the same process.


A user who delegates, bonds, or stakes XPLA to a validator to earn rewards. Delegating, bonding, and staking generally refer to the same process.


  • Gas: Compute fees added on to all transactions to avoid spamming. Validators set minimum gas prices and reject transactions that have implied gas prices below this threshold.

For more information on fees, visit Fees.

Full Node

A computer connected to the XPLA mainnet that is able to validate transactions and interact with the XPLA Chain. All active validators run full nodes.


The native staking token of the XPLA Chain. XPLA is also used as a governance token. Delegators can stake XPLA to receive rewards.


Governance is the democratic process that allows users and validators to make changes to the XPLA Chain. Community members submit, vote, and implement proposals. One staked XPLA is equal to one vote.

Governance Proposal

A written submission for a change or addition to the XPLA Chain. Topics of proposals can vary from community pool spending, software changes, or parameter changes.


Inter-Blockchain Communication. The technology that enables different blockchains to interact with each other. IBC allows for assets to be traded and transacted across different blockchains.

Inactive Set

Validators that are not in the active set. These validators do not participate in consensus and do not earn rewards.


Validators who misbehave are jailed or excluded from the active set for a period amount of time.


When a vote fails to be included in consensus.


A section of the XPLA Chain core that represents a particular function of the XPLA Chain. Visit the XPLA Chain core module specifications for more information.


The latest version of the mainnet


Groups of tokens. Supply pools represent the total supply of tokens in a market.

Proof of Stake

Proof of Stake. A style of blockchain where validators are chosen to propose blocks according to the number of coins they hold.


The minimum amount of votes needed to make an election viable. 33.4% of all staked XPLA must vote to meet quorum. If quorum is not met before the voting period ends, the proposal fails, and the proposer’s deposit is burned.


When a delegator wants to transfer their bonded XPLA to a different validator. Redelegating XPLA is instant and does not require a 21-day unbonding period.


Revenue generated from fees given to validators and disbursed to delegators.


The amount of XPLA a validator bonds to themselves. Also referred to as self-bond.


Punishment for validators that misbehave. Validators lose part of their stake when they get slashed.

For more information, see slashing in the description of the XPLA Chain.


The difference in a coin’s price between the start and end of a transaction.


The amount of XPLA bonded to a validator.


When a user delegates or bonds their XPLA to an active validator to receive rewards. Bonded XPLA adds to a validator’s stake. Validators provide their stakes as collateral to participate in the consensus process. Validators with larger stakes are chosen to participate more often. Validators receive staking rewards for their participation. A validator’s stake can be slashed if the validator misbehaves. Validators never have ownership of a delegator’s XPLA, even when staking.

For more information on staking, visit the concepts page.

Tendermint Consensus

The consensus procedure used by the XPLA Chain. First, a validator proposes a new block. Other validators vote on the block in two rounds. If a block receives a two-thirds majority or greater of yes votes in both rounds, it gets added to the blockchain. Validators get rewarded with the block’s transaction fees. Proposers get rewarded extra. Each validator is chosen to propose based on their weight. Check out the Tendermint official documentation for more information.

XPLA Chain Core

The official source code for the XPLA Chain.

For more information on the XPLA Chain core, see XPLA Chain core module specifications.


The XPLA Chain’s network where all transactions take place.

XPLA Vault

XPLA Chain’s native wallet and platform for swaps, governance, and staking. In XPLA Vault, you can send, receive, and stake XPLA coins. You can also participate in governance and vote on proposals.

To learn how to install and get started using XPLA Vault, visit the XPLA Vault tutorial.

To learn how to use the advanced features of XPLA Vault, visit the XPLA Vault how-to guide.


The command line interface for interacting with a XPLA Chain node.

For more information on xplad, see xplad guides.

xplavaloper Address

A validator’s public address beginning with xplavaloper followed by a string of characters.


A version of the mainnet just for testing. The testnet does not use real coins. You can use the testnet to get familiar with transactions. The current testnet for XPLA Chain is cube_47-5

The XPLA Chain Ecosystem

A quickly expanding network of decentralized applications built on the XPLA Chain.


To block a validator from participating in consensus. Tombstoned validators cannot rejoin the active set.

Total Stake

The total amount of XPLA bonded to a delegator, including self-bonded XPLA.

Unbonded Validator

A validator that is not in the active set and does not participate in consensus or receive rewards. Some unbonded validators may be jailed.

Unbonding Validator

A validator transitioning from the active set to the inactive set. An unbonding validator does not participate in consensus or earn rewards. The unbonding process takes 21 days.

Unbonded XPLA

XPLA that can be freely traded and is not staked to a validator.


When a delegator decides to undelegate their XPLA from a validator. This process takes 21 days. No rewards accrue during this period. This action cannot be stopped once executed.

Unbonding XPLA

XPLA that is transitioning from bonded to unbonded. XPLA that is unbonding cannot be traded freely. The unbonding process takes 21 days. No rewards accrue during this period. This action cannot be stopped once executed.


When a delegator no longer wants to have their XPLA bonded to a validator. This process takes 21 days. No rewards accrue during this period. This action cannot be stopped once executed.


The amount of time a validator is active in a given timeframe. Validators with low uptime may be slashed.


A XPLA Chain miner responsible for verifying transactions on the blockchain. Validators run programs called full nodes that allow them to participate in consensus, verify blocks, participate in governance, and receive rewards. The top 40 validators with the highest total stake can participate in consensus.

For more information on validators, visit the concepts page.


The measure of a validator’s total stake. Validators with higher weights get selected more often to propose blocks. A validator’s weight is also a measure of their voting power in governance.
