Types

type AppState

type AppState struct {
	DB     *model.DB
	Size   int64 `json:"size"`
	Height int64 `json:"height"`
}

func (AppState) Hash

func (s AppState) Hash() []byte

type Config

type Config struct {
	ChainID    string `toml:"chain_id"`
	CurseWords string `toml:"curse_words"`
}

func LoadConfig

func LoadConfig(file string) (*Config, error)

func (Config) Validate

func (cfg Config) Validate() error

Validate validates the configuration. We don't do exhaustive config validation here, instead relying on Testnet.Validate() to handle it.

type ForumApp

func (*ForumApp) ProcessProposal

func (app *ForumApp) ProcessProposal(_ context.Context, req *abci.ProcessProposalRequest) (*abci.ProcessProposalResponse, error)

ProcessProposal validates the proposed block and the transactions and return a status if it was accepted or rejected

func (*ForumApp) Query

func (app *ForumApp) Query(ctx context.Context, query *abci.QueryRequest) (*abci.QueryResponse, error)

Query the application state for specific information

func (*ForumApp) VerifyVoteExtension

func (app *ForumApp) VerifyVoteExtension(_ context.Context, req *abci.VerifyVoteExtensionRequest) (*abci.VerifyVoteExtensionResponse, error)

VerifyVoteExtension verifies the vote extensions and ensure they include the curse words It will not be called for extensions generated by this validator
