Turbo-Geth

GoDoc

Disclaimer: this software is currenly a tech preview. We will do our best to keep it stable and make no breaking changes but we don't guarantee anything. Things can and will break.

Turbo-Geth is a fork of Go-Ethereum with focus on performance.

The current version is currently based on Go-Ethereum 1.9.15.

Usage:

> make tg
> ./build/bin/tg

Key features

See more detailed overview of functionality and current limitations. It is being updated on recurring basis.

1. More Efficient State Storage

Flat KV storage. Turbo-Geth uses a key-value database and storing accounts and storage in a simple way. See our detailed DB walkthrough here.

Preprocessing. For some operations, turbo-geth uses temporary files to preprocess data before inserting it into the main DB. That reduces write amplification and DB inserts sometimes are orders of magnitude quicker.

Plain state.

Single accounts/state trie. Turbo-Geth uses a single Merkle trie for both accounts and the storage.

2. Faster Initial Sync

Turbo-Geth uses a rearchitected full sync algorithm from Go-Ethereum that is split into "stages".

It uses the same network primitives and is compatible with regular go-ethereum nodes that are using full sync, you do not need any special sync capabilities for turbo-geth to sync.

When reimagining the full sync, we focused on batching data together and minimize DB overwrites. That makes it possible to sync Ethereum mainnet in under 2 days if you have a fast enough network connection and an SSD drive.

Examples of stages are:

• Downloading headers;

• Downloading block bodies;

• Executing blocks;

• Validating root hashes and building intermediate hashes for the state Merkle trie;

• And more...

3. JSON-RPC daemon

In turbo-geth RPC calls are extracted out of the main binary into a separate daemon. This daemon can use both local or remote DBs. That means, that this RPC daemon doesn't have to be running on the same machine as the main turbo-geth binary or it can run from a snapshot of a database for read-only calls.

For local DB

> make rpcdaemon
> ./build/bin/rpcdaemon --chaindata ~/Library/TurboGeth/tg/chaindata --http.api=eth,debug

For remote DB

Run turbo-geth in one terminal window

> ./build/bin/tg --private.api.addr=localhost:9090

Run RPC daemon

> ./build/bin/rpcdaemon --private.api.addr=localhost:9090

---

Currently supported JSON-RPC calls:

• eth_call

• eth_getBlockByHash

• eth_getBlock

• eth_blockNumber

• eth_getBalance

• eth_getLogs

• eth_estimateGas

• debug_storageRangeAt

• debug_traceTransaction

• debug_accountRange

• debug_getModifiedAccountsByNumber

• debug_getModifiedAccountsByHash

4. REST API Daemon

Apart from JSON-RPC daemon, Turbo-Geth also contains REST API daemon. It uses turbo-geth remote DB functionality.

Run turbo-geth in one terminal window

> ./build/bin/tg --private.api.addr=localhost:9090

Run REST daemon

> make restapi
> ./build/bin/restapi --private.api.addr=localhost:9090

This API is very limited at the moment too:

GET /api/v1/accounts/<accountAddress>
GET /api/v1/storage/?prefix=PREFIX
