Break Solana Game 
How it works
The Break Solana Game consists of a 3 parts: a web client frontend, a web server backend, and an on-chain Solana program. The web server backend is not strictly required but it helps with certain performance improvements.
At a basic level, the Break Solana Game allows a player to send simple smart contract transactions as fast as they can to showcase Solana's speed. The web frontend is responsible for creating, sending, and confirming transactions and displays the status of each transaction in a colored grid. The web backend helps out by acting as a fast relay for transactions. It will forward transactions directly to the TPU (transaction processing unit) UDP port of the current cluster leader node (typically transactions are first sent to an RPC API node for forwarding). It also helps by creating a supply of game accounts ahead of time to speed up game setup time (these accounts can be tracked across server restarts using Redis).
Rather than subscribing to each transaction signature, the web client subscribes to account data updates. Each transaction will set a bit in the state within a Break program account, so each transaction can be uniquely identified by the bit it sets.
Prerequisites
Solana CLI Tooling: https://docs.solana.com/cli/install-solana-cli-tools For running this application you need to have NodeJs and NPM. We recommend to use NVM for managing NodeJs versions For NVM installation please refer to manual
Install
npm install
Run Server
Note: If the cluster you connect to doesn't provide a faucet, you will need to supply the server with a payer key. (See 'Configuration' below).
# Start local node
solana-test-validator
# Deploy program to local node
cd program
cargo build-bpf
solana program deploy target/deploy/break_solana_program.so --url localhost
# Connect to local node
cd server
npm run start:dev
Configuration
By default, the Break server will connect to a local node for RPC. To configure this behavior, set the following environment variables when running the server:
PORT
Set this option to specify the port for the API server. Default is 8080.
PORT=80 npm run start:dev
RPC_URL
Set this option to connect to a specific remote RPC API server.
RPC_URL=http://api.mainnet-beta.solana.com npm run start:dev
LIVE
Enable this option to connect to a remote cluster. The default cluster is devnet.
LIVE=true npm run start:dev
CLUSTER
Enable this option along with LIVE=true to connect to a specific remote cluster.
LIVE=true CLUSTER=devnet npm run start:dev
LIVE=true CLUSTER=testnet npm run start:dev
LIVE=true CLUSTER=mainnet-beta npm run start:dev
DEPLOYED_PROGRAM_ADDRESS
Set this option to use an existing loaded Break Solana program rather than load a new version. If the program doesn't exist, the server will exit with an error.
DEPLOYED_PROGRAM_ADDRESS=<BASE58 ENCODED ADDRESS> npm run start:dev
To use the Break Solana program that's used on https://break.solana.com, use the following address:
DEPLOYED_PROGRAM_ADDRESS=BrEAK7zGZ6dM71zUDACDqJnekihmwF15noTddWTsknjC npm run start:dev
SEND_TO_RPC
Enable this option to send transactions to the RPC API rather than directly to a validator TPU port.
SEND_TO_RPC=true npm run start:dev
Run Client
cd client
npm run start
Configuration
Client behavior can be modified with the usage of url parameters.
cluster
Set this parameter to pick a remote cluster. This parameter is automatically set when using the UI cluster selector.

commitment
Set this parameter to set the commitment level used for confirming transactions. Default is 'confirmed' but 'processed'
is also supported.
https://break.solana.com/game?commitment=processed
debug
Set this parameter to enable "debug mode" which will display a table of confirmation times instead of the colored grid.

retry
Set this parameter to disable retrying transactions which have not yet been confirmed. Retry behavior is enabled by default because some transactions will be forwarded to a leader who skips their block slot.
https://break.solana.com/game?retry=disabled
split
Set this parameter to split transactions across multiple payer and program accounts to increase transaction parallelization. Default is 4.
https://break.solana.com/game?split=1
test
Set this parameter to enable "test mode" which will automatically send approximately 33 transactions per second.
