The Matic team has put together a Proof-of-Concept for the Reddit Scaling Bake-Off. We think Matic is the most apt solution for the scaling requirements of Reddit, keeping in mind it’s current and future needs.

We believe that the Matic Layer 2 platform is the most complete solution out there in terms of the features and fits right in with what Reddit requires:

• Security via Plasma predicates on Ethereum: Reliable exits to Ethereum (Proof-of-Stake based decentralized multi-operator Plasma construction which mitigates mass exit occurrence)
• Composability (EVM Support),
• Extremely high scalability with each sidechain (multiple sidechains in future, hence suitable for the scale of Reddit)
• Ability to add custom smart contract features (via Ethereum Plasma predicates) for future product innovation

***TL;DR:*** *The Matic sidechain processed 3mn transactions over 12 hours with total gas fees of USD 3.52 as part of the Great Reddit Scaling Bake-Off PoC.*

The PoC used a few addresses only for the purpose of the demo, and the total throughput with millions of user addresses can go up to 7200 TPS per sidechain and these 3mn transactions could've been completed in a matter of 10-11mins.

The PoC touches upon various aspects of the solution required – scalability that will need to meet Reddit’s requirements over time (more subreddits using Community Points), faster transaction times, inexpensive minting of Community Points, decentralization, accessible developer tooling, use of meta-transactions to pay for gas on behalf of users, open-source code, extensibility, ability to exit back to Ethereum, if needed and more.

• *What is Matic?**

Matic Network is a Layer 2 scaling solution for Ethereum that provides hybrid Proof-of-Stake and Plasma-enabled sidechains. We just released version 1 of our mainnet in May 2020 – https://blog.matic.network/the-matic-network-mainnet-is-now-live/[1][2].

Matic implements an account-based variant of MoreVP (More Viable Plasma[3]), with support for custom Plasma predicates[4]. The Plasma framework with predicates is used to guarantee the security of assets and specific smart contracts using Plasma predicates, while arbitrary smart contracts are secured by a Proof-of-Stake network, with validators staking Matic tokens on Ethereum. Matic sidechains are essentially EVM-enabled chains and are conducive to ready deployment of Solidity smart contracts, essentially making it an easy tool for Ethereum developers to use it for scaling their DApps/Protocols.

• *We are submitting the following:**

• A live proof-of-concept which demonstrates the scale required for the bakeoff and future requirements * **We did over 3,000,000 (3 million) transactions in our scaling PoC bulk run over a period of ~12 hours (yes that’s 3 mn transactions):** * 1,000,000 point claims (minting & distributing points) * 1,000,000 subscriptions and 1,000,000 burns * 1,000,000 transfers * Video to showcase our benchmarking[5] * Proof-of-Concept repo – https://github.com/maticnetwork/reddit-bakeoff-poc[6][7] * A detailed explanation of the demo is given here: https://github.com/maticnetwork/reddit-bakeoff-poc/blob/develop/README.md[8][9] * The following contracts have been deployed on Mumbai testnet[10] – * SubredditPoints: 0xc4f93FeF8086c452134B0F15a5AE963ACe6A7748[11] * Distributions: 0xd7ab2634121e7afCE48b2A8Ea5db908869158D3E[12] * Subscriptions: 0x94B8f2A9a36Be215F2D4211DFee523f204f0a897[13] * Refer https://github.com/maticnetwork/reddit-bakeoff-poc/blob/develop/README.md#workflows[14][15] for the end-to-end flow of the PoC * User requests a claim from Owner account, and submits the claim to the distributions contract which then (internally) calls Subreddit Points contract to mint tokens. * User can transfer SubredditPoints tokens to another user * User submits subscribe transaction to place a subscription intent, thereby burning some amount of their tokens. * Wiki for more information on the PoC and relevant Matic links can be found here: https://github.com/maticnetwork/reddit-bakeoff-poc/wiki[16][17] * Single user scripts can be found here – https://github.com/maticnetwork/reddit-bakeoff-poc/tree/develop/scripts[18][19] * Single user scripts with meta-transaction support (gas to be paid on behalf of the user) can be found here: * Gas Station Network[20]: https://github.com/maticnetwork/reddit-bakeoff-poc/tree/gsn[21][22] * Bulk transaction scripts can be found here: https://github.com/maticnetwork/reddit-bakeoff-poc/tree/reddit%5C_benchmark[23][24] * The bulk transaction run of 3 million transactions can be found here * Bulk transaction logs can be found here: https://drive.google.com/%E2%80%A6/1r1X0RNTIpE0w4MY599t9TO8PHvdQXqqz[25][26] * A previous run of the bulk transactions having 300k transactions can be found here – https://www.notion.so/maticnetwork/Reddit-PoC-bulk-transaction-script-results-5aac772b3c0b424b93c7700ad53dc30c[27][28] * Total cost of the PoC (1 mn transactions each – total 3 mn txs) – ~3.52 US$ at current price * Claim and mint points: ~71 Matic tokens (~1.4 US$) * Subscribe and burn points: ~52 Matic tokens (~1.02 US$) * Transfer points: ~56 Matic tokens (~1.1 US$)
• A live mainnet (we just launched in May 2020 after 2+ years of development!)
• Very cheap transactions
• Atleast ~4000 TPS, but we have gotten around 17,000 TPS while benchmarking[29]
• Block time is ~2 seconds
• Code[30], which is already open source – audited by 3 different audit firms
• Documentation[31], including architecture[32]
• EVM compatible interface – web3js[33] and other web3 library support
• Standard Solidity support to enable existing smart contracts to be deployed without major rework
• EVM compatibility results in support for all Ethereum developer and user tooling * Most wallets such as Portis[34], Torus[35], Fortmatic[36], Metamask[37] and others already have support for the Matic mainnet sidechain * Most libraries[38] readily usable on Matic * Compatibility with common utilities & toolchains * Third-party permissionless integrations[39] * HSM and hardware wallet support
• Account-based Plasma MoreVP implementation[40], with Plasma predicates[41] support to enable more expressive, custom fraud proofs, if required * Reddit smart contracts can be modified and appropriate fraud proofs via predicates can be written to ensure changes can be done later
• Decentralization:[42] Validators operating the Plasma chain need to stake Matic tokens on our staking smart contracts deployed on Ethereum. They can be slashed in case they resort to adversarial behavior.
• GSN[43] and Biconomy[44] support for meta-transactions (Reddit can pay gas fees on behalf of their users)
• Fast exits/withdrawals[45] from Ethereum to Matic via our tokenized NFT/ERC721 exit mechanism * https://medium.com/matic-network/enabling-faster-plasma-exits-3ca5a936f215[46][47] * https://github.com/maticnetwork/reddit-bakeoff-poc/wiki/Withdraw:-How-to-exit-from-Matic-chain[48][49]
• Fully functional Blockchain explorer[50]
• Tokens can be withdrawn to Ethereum in case the Matic sidechain goes down by way of our Plasma MoreVP[51] mechanism
• Plasma contracts have been audited by a leading audit firm
• Inexpensive minting on Matic directly * As and when users do want to exit to Ethereum, they can do so via the MintableERC20[52] predicate. Once they exit to Ethereum, the exited token amount is burned on the Matic sidechain and correspondingly minted on the mapped Ethereum Subreddit ERC20 token contract. The only requirement here is that the Ethereum and Matic ERC20 token contracts be mapped in advance once in the Matic Plasma contracts on Ethereum.

Here is Matic's proposal to scale Reddit on Ethereum.

​

Hello Ethereum community,

Happy to answer any questions you might have.

Great work, very impressive numbers

Proof-of-Stake based decentralized multi-operator Plasma construction which mitigates mass exit occurrence

How many operators were running during these benchmarks?

How many ought to run for the side-chain to be secure?

Extremely high scalability with each sidechain (multiple sidechains in future, hence suitable for the scale of Reddit)

If you were designing a Matic-Reddit integration, would you consider running a separate side chain for each subreddit vs one side-chain for all subreddits?

Matic proving to be the most scalable, usable and secure solution that Reddit requires. Hats off to the team who put together this PoC.

Crisp and precise explanation unlike certain others.

1285$ per year for more than 1B transactions.

If I did this on Ethereum right now, I’d be 1B$ poorer. Good thing I don’t have 1B 😂

Thanks Matic for giving me an opportunity to do things only billionaires can do <3

I'll put in my vote for Matic. They have the tech needed to solve this. No question about it. They utilize the security and decentralization of Ethereum, with the speed and scalability of Plasma.

I see Matic being as successful and helpful to Ethereum as Lightning Network for Bitcoin.

this is good! the only thing that let me think is , you calculate the price of using your L2 system with matic tokens(you used 179 tokens in this example) but what if the price of the token will skyrocket during a bull run-like it will go 20x that in crypto isn't to far fetched- will the price of the L2 skyrocket too?

Reddit have found their scaling solution here in Matic Network. This submission is absolutely stunning. The numbers are so impressive. Honestly, $3.52 for 3m transactions, Ethereum can only dream of that.

Matic Network, I tip my hat to your team for this excellent work and I'm extremely confident you guys will get the gig.
