Measure latency from broadcasting a transaction to its inclusion in a block:

```

(broadcast tx) -> (first appeareance of a block) -> (block timestamp)

```

Transaction is sent directly with `eth_sendRawTransaction` RPC call. All related 

calls necessary to make a transaction (gas, block number, nonce) were done

outside of timing window for higher measurement accuracy.

# Configure

```sh

# setup dotenv file

cp .env.example .env

# edit the config according to comments inside

vim .env

```

Make sure you have `deno` and `duckdb` installed

# Usage

```sh

# start broadcasting and tracking transactions

deno run -A main.ts | tee /dev/tty | rg -r '' '\t' > out/events.jsonl

# dump stats

duckdb < events.sql

```
