 * **Gas Meters:** Specifically, a [`gasMeter`](../beginner/04-gas-fees.md#main-gas-meter) for the transaction currently being processed using the context and a [`blockGasMeter`](../beginner/04-gas-fees.md#block-gas-meter) for the entire block it belongs to. Users specify how much in fees they wish to pay for the execution of their transaction; these gas meters keep track of how much [gas](../beginner/04-gas-fees.md) has been used in the transaction or block so far. If the gas meter runs out, execution halts.
 * **CheckTx Mode:** A boolean value indicating whether a transaction should be processed in `CheckTx` or `DeliverTx` mode.
 * **Min Gas Price:** The minimum [gas](../beginner/04-gas-fees.md) price a node is willing to take in order to include a transaction in its block. This price is a local value configured by each node individually, and should therefore **not be used in any functions used in sequences leading to state-transitions**.
-* **Consensus Params:** The ABCI type [Consensus Parameters](https://docs.cometbft.com/v0.37/spec/abci/abci++_methods#consensus_param_updates), which specify certain limits for the blockchain, such as maximum gas for a block.

 * **Event Manager:** The event manager allows any caller with access to a `Context` to emit [`Events`](./08-events.md). Modules may define module specific
   `Events` by defining various `Types` and `Attributes` or use the common definitions found in `types/`. Clients can subscribe or query for these `Events`. These `Events` are collected throughout `FinalizeBlock` and are returned to CometBFT for indexing.
 * **Priority:** The transaction priority, only relevant in `CheckTx`.

 A copy of the cached context is provided to the `AnteHandler`, which performs limited checks specified for the transaction type. Using a copy allows the `AnteHandler` to do stateful checks for `Tx` without modifying the last committed state, and revert back to the original if the execution fails.
 
-For example, the [`auth`](https://github.com/cosmos/cosmos-sdk/tree/main/x/auth/spec) module `AnteHandler` checks and increments sequence numbers, checks signatures and account numbers, and deducts fees from the first signer of the transaction - all state changes are made using the `checkState`.

 :::warning
 Ante handlers only run on a transaction. If a transaction embed multiple messages (like some x/authz, x/gov transactions for instance), the ante handlers only have awareness of the outer message. Inner messages are mostly directly routed to the [message router](https://docs.cosmos.network/main/learn/advanced/baseapp#msg-service-router) and will skip the chain of ante handlers. Keep that in mind when designing your own ante handler.
