# Brave THEMIS
|
|
|
|
An implementation of Brave's THEMIS research project. This project contains
|
|
two privacy-oriented smart contracts, the Policy Smart Contract (PSC) and
|
|
the Fund Smart Contract (FSC). Together, the two contracts allow users to
|
|
be compensated for engaging with ad publishers. The users do not expose
|
|
their identities or preferences.
|
|
|
|
## Build and Run the TPS demo client
|
|
|
|
The demo client simulates 1,000 users interacting with the Ristretto
|
|
version of the THEMIS on-chain program.
|
|
|
|
### Install prerequisites
|
|
|
|
Create an Ubuntu 20.04 instance with at least 8GB of memory and 20 GB of
|
|
disk space.
|
|
|
|
Install system dependencies:
|
|
|
|
```bash
|
|
sudo apt update
|
|
sudo apt install -y g++ libclang-dev pkg-config make libssl-dev libudev-dev
|
|
```
|
|
|
|
Install the Rust compiler:
|
|
|
|
```
|
|
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
|
|
source $HOME/.cargo/env
|
|
```
|
|
|
|
Install the Solana command-line tools:
|
|
|
|
```bash
|
|
curl -sSf https://raw.githubusercontent.com/solana-labs/solana/v1.4.2/install/solana-install-init.sh | sh -s - v1.4.2
|
|
export PATH="$HOME/.local/share/solana/install/active_release/bin:$PATH"
|
|
```
|
|
|
|
### Build the TPS example app
|
|
|
|
Clone this git repo:
|
|
|
|
```bash
|
|
git clone https://github.com/solana-labs/solana-program-library.git
|
|
cd solana-program-library
|
|
```
|
|
|
|
Build the demo client:
|
|
|
|
```bash
|
|
cd themis/client_ristretto
|
|
cargo build --example tps
|
|
```
|
|
|
|
### Configure the default Solana wallet
|
|
|
|
Point to the testnet cluster (default is mainnet-beta):
|
|
|
|
```bash
|
|
solana config set --url http://testnet.solana.com
|
|
```
|
|
|
|
Create a keypair and airdrop it some SOL:
|
|
|
|
```bash
|
|
solana-keygen new --no-passphrase
|
|
solana airdrop 10
|
|
```
|
|
|
|
### Run the TPS example app
|
|
|
|
```bash
|
|
cargo run --example tps
|
|
```
|
|
|
|
You should see something like:
|
|
|
|
```bash
|
|
Seeding feepayer accounts...
|
|
Starting benchmark...
|
|
Benchmark complete.
|
|
4000 transactions in 27.880907273s (143.4673542303847 TPS)
|
|
```
