Legacy types are defined below to aid in the migration of CometBFT consensus parameters from use of the now deprecated x/params modules to a new dedicated x/consensus module.

Application developers should ensure that they implement their upgrade handler correctly such that app.ConsensusParamsKeeper.Set() is called with the values returned by GetConsensusParams().


baseAppLegacySS := app.ParamsKeeper.Subspace(baseapp.Paramspace).WithKeyTable(paramstypes.ConsensusParamsKeyTable())

	func(ctx sdk.Context, plan upgradetypes.Plan, fromVM module.VersionMap) (module.VersionMap, error) {
		if cp := baseapp.GetConsensusParams(ctx, baseAppLegacySS); cp != nil {
			app.ConsensusParamsKeeper.Set(ctx, cp)
		} else {
			ctx.Logger().Info("warning: consensus parameters are undefined; skipping migration", "upgrade", UpgradeName)

		return app.ModuleManager.RunMigrations(ctx, app.Configurator(), fromVM)

Developers can also bypass the use of the legacy Params subspace and set the values to app.ConsensusParamsKeeper.Set() explicitly.

Note, for new chains this is not necessary as CometBFT's consensus parameters will automatically be set for you in InitChain.

It calls the application's ExtendVote handler which is responsible for performing application-specific business logic when sending a pre-commit for the NEXT block height. The extensions response may be non-deterministic but must always be returned, even if empty.

Agreed upon vote extensions are made available to the proposer of the next height and are committed in the subsequent height, i.e. H+2. An error is returned if vote extensions are not enabled or if extendVote fails or panics.

For each raw transaction, i.e. a byte slice, BaseApp will only execute it if it adheres to the sdk.Tx interface. Otherwise, the raw transaction will be skipped. This is to support compatibility with proposers injecting vote extensions into the proposal, which should not themselves be executed in cases where they adhere to the sdk.Tx interface.

func (app *BaseApp) GRPCQueryRouter() *GRPCQueryRouter

GRPCQueryRouter returns the GRPCQueryRouter of a BaseApp.

func (*BaseApp) GetBlockRetentionHeight added in v0.40.0

func (app *BaseApp) GetBlockRetentionHeight(commitHeight int64) int64

GetBlockRetentionHeight returns the height for which all blocks below this height are pruned from CometBFT. Given a commitment height and a non-zero local minRetainBlocks configuration, the retentionHeight is the smallest height that satisfies:

- Unbonding (safety threshold) time: The block interval in which validators can be economically punished for misbehavior. Blocks in this interval must be auditable e.g. by the light client.

- Logical store snapshot interval: The block interval at which the underlying logical store database is persisted to disk, e.g. every 10000 heights. Blocks since the last IAVL snapshot must be available for replay on application restart.

- State sync snapshots: Blocks since the oldest available snapshot must be available for state sync nodes to catch up (oldest because a node may be restoring an old snapshot while a new snapshot was taken).

- Local (minRetainBlocks) config: Archive nodes may want to retain more or all blocks, e.g. via a local config option min-retain-blocks. There may also be a need to vary retention for other nodes, e.g. sentry nodes which do not need historical blocks.

func (app *BaseApp) PrepareProposal(req *abci.RequestPrepareProposal) (resp *abci.ResponsePrepareProposal, err error)

PrepareProposal implements the PrepareProposal ABCI method and returns a ResponsePrepareProposal object to the client. The PrepareProposal method is responsible for allowing the block proposer to perform application-dependent work in a block before proposing it.

Transactions can be modified, removed, or added by the application. Since the application maintains its own local mempool, it will ignore the transactions provided to it in RequestPrepareProposal. Instead, it will determine which transactions to return based on the mempool's semantics and the MaxTxBytes provided by the client's request.

Ref: Ref:

func (*BaseApp) PrepareProposalVerifyTx added in v0.47.0

func (app *BaseApp) PrepareProposalVerifyTx(tx sdk.Tx) ([]byte, error)

PrepareProposalVerifyTx performs transaction verification when a proposer is creating a block proposal during PrepareProposal.

func (*BaseApp) ProcessProposal added in v0.47.0

func (app *BaseApp) ProcessProposal(req *abci.RequestProcessProposal) (resp *abci.ResponseProcessProposal, err error)

ProcessProposal implements the ProcessProposal ABCI method and returns a ResponseProcessProposal object to the client. The ProcessProposal method is responsible for allowing execution of application-dependent work in a proposed block. Note, the application defines the exact implementation details of ProcessProposal. In general, the application must at the very least ensure that all transactions are valid. If all transactions are valid, then we inform CometBFT that the Status is ACCEPT. However, the application is also able to implement optimizations such as executing the entire proposed block immediately.

If a panic is detected during execution of an application's ProcessProposal handler, it will be recovered and we will reject the proposal.

Ref: Ref:

func (*BaseApp) ProcessProposalVerifyTx added in v0.47.0

func NewDefaultProposalHandler(mp mempool.Mempool, txVerifier ProposalTxVerifier) *DefaultProposalHandler

func (*DefaultProposalHandler) PrepareProposalHandler added in v0.47.0

func (h *DefaultProposalHandler) PrepareProposalHandler() sdk.PrepareProposalHandler

PrepareProposalHandler returns the default implementation for processing an ABCI proposal. The application's mempool is enumerated and all valid transactions are added to the proposal. Transactions are valid if they:

1) Successfully encode to bytes. 2) Are valid (i.e. pass runTx, AnteHandler only).

Enumeration is halted once RequestPrepareProposal.MaxBytes of transactions is reached or the mempool is exhausted.


- Step (2) is identical to the validation step performed in DefaultProcessProposal. It is very important that the same validation logic is used in both steps, and applications must ensure that this is the case in non-default handlers.

- If no mempool is set or if the mempool is a no-op mempool, the transactions requested from CometBFT will simply be returned, which, by default, are in FIFO order.

func (*DefaultProposalHandler) ProcessProposalHandler added in v0.47.0

func (h *DefaultProposalHandler) ProcessProposalHandler() sdk.ProcessProposalHandler

ProcessProposalHandler returns the default implementation for processing an ABCI proposal. Every transaction in the proposal must pass 2 conditions:

1. The transaction bytes must decode to a valid transaction. 2. The transaction must be valid (i.e. pass runTx, AnteHandler only)

If any transaction fails to pass either condition, the proposal is rejected. Note that step (2) is identical to the validation step performed in DefaultPrepareProposal. It is very important that the same validation logic is used in both steps, and applications must ensure that this is the case in non-default handlers.
