The last submissions to the Great Reddit Scaling Back-Off were submitted with the deadline being the 31st of July 2020.

Due to the amount of Layer 2 scaling Ethereum solutions out there, all at varying degrees of success, the Reddit team made a public challenge to submit a working demo meeting their scaling requirements.

What were the Scaling Requirements of Reddit’s Crypto Community Points?

  • The demo must be a live proof of concept that simulates Community Points usage for 100,000 users (It will eventually scale to all of Reddit’s 430 million users)
  • Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
  • Over a 5 day period, your scaling PoC should be able to handle:
    • 100,000 point claims (minting & distributing points)
    • 25,000 subscriptions
    • 75,000 one-off points burning
    • 100,000 transfers

So How Did Solana Go in the Reddit Scaling Bake-Off?

We crushed the challenge in 5 minutes 40 seconds. The total cost was 5 SOL or about $5 to $7 USD. Check out the video below to listen to Anatoly (Solana CEO) talk about the innovations of Solana and how it will continue to scale up every year as industry standard hardware and network bandwidth also scales.

How Can Solana Help Reddit’s Community Points System Scale?

Solana doesn’t mess around with vague GWEI, Gas and Channels. It is a no bullshit no sharding blockchain that scales up with industry standard hardware and network bandwidth. It is built by engineers from Qualcomm who scale telecommunication cellular solutions to millions of users.

Just to summarise, Solana is fast and cheap:

  • Max. Transactions Per Second: 59,490
  • Block times: 400ms
  • Cost per Transaction: $0.00001
  • Decentralised across 130+ independent validator nodes
  • You can build smart contracts with Rust

How Did Solana Compare to Other Reddit Scaling Bake-Off Submissions?

This comparison table is subject to change and is based off researching each submission. Hopefully, the scaling solution lists their result for meeting Reddit’s requirement of processing ~300,000 transactions in Time & Cost (100k point claims, 25k subs, 75k points burning & 100k transfers). If it doesn’t results may be inaccurate and is marked with “?”. Sources have been linked to the results.

Above results are based off researching each Reddit Bake Off submission and specifically looking for Time & Cost for completing the Reddit required activities.

After Reddit picks Solana as the winner of the scaling bake-off, we’re going to work tirelessly to make sure we can roll out the features that Reddit wants, like community points, to the entire 430 million Reddit user base.
