# Root updater [](https://github.com/tornadocash/tornado-root-updater/actions) [](https://hub.docker.com/repository/docker/tornadocash/tornado-root-updater)
|
||||||
|
|
||||||
|
For Tornado Cash to enable mining, it needs more metadata than is currently available: it needs to know the block number for each Tornado Cash deposit and withdrawal. Since the current version of Tornado cash is immutable the mining system uses a special proxy to collect this data. When users make deposits and withdrawal all necessary data is recorded to the [proxy](https://github.com/tornadocash/tornado-anonymity-mining/blob/master/contracts/TornadoProxy.sol) contract. In order to be used in zkSnark proof, this data should be added to the special Merkle trees (deposits Merkle tree and withdrawals Merkle tree). So long as someone out there does this, the system works smoothly and trustlessly.
|
||||||
|
|
||||||
|
This software helps to upload deposit and withdrawal metadata from Tornado Cash anonymity mining [proxy](https://github.com/tornadocash/tornado-anonymity-mining/blob/master/contracts/TornadoProxy.sol) into the [TornadoTrees](https://github.com/tornadocash/tornado-anonymity-mining/blob/master/contracts/TornadoTrees.sol) contract that handles the Merkle trees.
|
||||||
|
|
||||||
|
Keep in mind, it could cost some ether to do so.
|
||||||
|
|
||||||
|
## Usage with docker
|
||||||
|
|
||||||
|
```shell script
|
||||||
|
wget https://raw.githubusercontent.com/tornadocash/tornado-root-updater/master/docker-compose.yml
|
||||||
|
wget https://raw.githubusercontent.com/tornadocash/tornado-root-updater/master/.env.example -O .env
|
||||||
|
vi .env # update env vars
|
||||||
|
docker-compose up -d
|
||||||
|
```
|
||||||
|
|
||||||
|
## Usage for development
|
||||||
|
|
||||||
|
```shell script
|
||||||
|
brew install redis
|
||||||
|
redis-server
|
||||||
|
|
||||||
|
yarn
|
||||||
|
cp .env.example .env
|
||||||
|
vi .env
|
||||||
|
# download and unzip snark keys from https://tornado-trees-circuit.s3-eu-west-1.amazonaws.com/tornado-trees-circuit.tar.gz to `snarks` directory
|
||||||
|
yarn start
|
||||||
|
```
|
||||||
|
|
||||||
|
Caches events from both mining and tornado cash instances
