Tiger_beetle_simulation

Project Details

This challenge is designed to test your ability to deal with a completely new technology (in this case TigerBeetle) and your ability to do research into things you’ve probably never dealt with.

TigerBeetle is a new open source database that has been primarily built for financial transactions.

They claim to do 800K txn/sec, we want to see how true that is!

Visa currently has capacity to process 50K/txn per second Stripe - a global leader in payments handled over 27K txn/second

In order to test the claims of TigerBeetle, your task is to:

1. Create a micro-payments system, with the following subtask:

• Setup TigerBeetle either on localhost or on your preferred cloud.
• Intialize two users X and Y with an intial balance of 100 each.

Next Implement a transactions engine that has the following parameters

• A signing mechanism Public Key to associate the balance and a Private Key to sign the transaction. (Choose your preferred signing algorithm)
• Create endpoints to send a transactions with micro-payments such as 0.01 and even lesser, which are digitally signed { i.e, a user sends a transaction which is signed by a particular private key }

Next

• Set up a backend server which verifies these transactions, checks there is no double spending { hence we need a nonce in transaction format }, and then does the transfer to the other account. [Do your own research on how blockchain payment systems enables transactions using NONCE and implement a simplified transaction scheme]
• Benchmark this system, to check how many transactions per second it can do!

Log the results and show us your code.

Tech used

• Nodejs v16.20.2
• Docker.
• Tiger Beetle Database.
• Grafana K6 for load testing.
• Pino for Logging.

Running a single node cluster

• Run the below command and makes sure to have docker installed and setup locally.

npm run prepare:tigerbeetle

This will create a data folder in the current directory.

• Run the below command to start the tiger beetle server

npm run start:tigerbeetle

• For any issues occuring while using on docker desktop please apply the below solution

Go to docker desktop > setting > Docker Engine and add the below scripts, and make sure there are no trailing commas

  "default-ulimits": {
    "memlock": {
      "Hard": -1,
      "Name": "memlock",
      "Soft": -1
    }
  }

Now delete data folder and restart docker and try again.

Running the server

npm install

npm run start:server

Running the Benchmark

The benchmarking is done using Grafana's K6 testing tool. This requires installation of the K6.

Installation guide link.

Running the benchmark

k6 run k6.test.js   

Feel free to adjust the options of K6 in k6.test.js file. It looks something like below.

export const options = {
  vus: 1000,
  duration: "10s",
};
