## Usage

```go

import (

	"context"

	"time"

	"os"

	"os/signal"

	"syscall"

	"github.com/scorum/event-provider-go/event"

	"github.com/scorum/event-provider-go/provider"

	log "github.com/sirupsen/logrus"

)

func main() {

	provider := provider.NewProvider("https://testnet.scorum.com", provider.SyncInterval(time.Second))

	ctx, cancel := context.WithCancel(context.Background())

	blocksCh, irreversibleBlocksCh, errorCh := provider.Provide(ctx, 2220447, 2220447,

		[]event.Type{event.CommentEventType, event.PostEventType, event.VoteEventType, event.FlagEventType})

	sigCh := make(chan os.Signal, 1)

	signal.Notify(sigCh,

		syscall.SIGHUP,

		syscall.SIGINT,

		syscall.SIGTERM,

		syscall.SIGQUIT)

	go func() {

		<-sigCh

		cancel()

	}()

	for {

		select {

		case e := <-errorCh:

			panic(e)

		case <-ctx.Done():

			return

		case b := <-blocksCh:

			log.Infof("reversible block %d with %d operations", b.BlockNum, len(b.Events))

		case b := <-irreversibleBlocksCh:

			log.Infof("irreversible block %d with %d operations", b.BlockNum, len(b.Events))

		}

	}

}
