# Lite RPC
|
|
|
|
Submitting a [transaction](https://docs.solana.com/terminology#transaction) to be executed on the solana blockchain,
|
|
requires the client to identify the next few leaders based on the
|
|
[leader schedule](https://docs.solana.com/terminology#leader-schedule), look up their peering information in gossip and
|
|
connect to them via the [quic protocol](https://en.wikipedia.org/wiki/QUIC). In order to simplify the
|
|
process so it can be triggered from a web browser, most applications
|
|
run full [validators](https://docs.solana.com/terminology#validator) that forward the transactions according to the
|
|
protocol on behalf of the web browser. Running full solana [validators](https://docs.solana.com/terminology#validator)
|
|
is incredibly resource intensive `(>256GB RAM)`, the goal of this
|
|
project would be to create a specialized micro-service that allows
|
|
to deploy this logic quickly and allows [horizontal scalability](https://en.wikipedia.org/wiki/Scalability) with
|
|
commodity vms.
|
|
|
|
### Confirmation strategies
|
|
|
|
1) Subscribe to new blocks using [blockSubscribe](https://docs.solana.com/developing/clients/jsonrpc-api#blocksubscribe---unstable-disabled-by-default)
|
|
2) Subscribing to signatures with pool of rpc servers. (Under development)
|
|
3) Listining to gossip protocol. (Future roadmap)
|
|
|
|
## Executing
|
|
|
|
*make sure `solana-validator` is running in the background with `--rpc-pubsub-enable-block-subscription`*
|
|
|
|
*run using*
|
|
```bash
|
|
$ cargo run --release
|
|
```
|
|
|
|
*to know about command line options*
|
|
```bash
|
|
$ cargo run --release -- --help
|
|
```
|
|
|
|
## Test and Bench
|
|
|
|
*Make sure both `solana-validator` and `lite-rpc` is running*
|
|
|
|
*test*
|
|
```bash
|
|
$ cargo test
|
|
```
|
|
|
|
*bench*
|
|
```bash
|
|
$ cargo bench
|
|
```
|
|
|
|
Find a new file named `metrics.csv` in the project root.
