Best Layer 2 Protocols

SX’s mission is simple, we aim to slash betting costs by 90% from 4.8% to 0.5%. This represents a 10x improvement from the industry standard odds. In simple terms, this means a $100 bet on a 50–50 outcome pays you $99 in profit, a 10% higher payout for bettors. SX Network is a peer-to-peer betting exchange that allows all users to both offer and take bets. This is different from traditional sportsbooks where users can only take bets offered by the company running the site. This peer-to-peer model of betting leads to better odds and removes the ability of owners to exploit the users for profit. SX Bet is built on its own custom EVM-compatible blockchain, making it the first ever fully integrated betting app chain. SX treats sports betting like a financial market where you can win, not a casino where you can only lose. Every time a user wins a bet, they not only receive their winnings but also earn SX tokens.

MegaETH is a next-generation blockchain execution platform built to deliver extreme performance and efficiency for decentralized applications and high-throughput workloads. To achieve this, MegaETH introduces a new state trie design that scales smoothly to terabytes of state data with minimal I/O cost. It implements a write-optimized storage backend to replace traditional high-amplification databases, ensuring fast, predictable read and write latencies. It uses just-in-time bytecode compilation to eliminate interpretation overhead and bring near native code speed to compute-intensive smart contracts. MegaETH also supports a two-pronged parallel execution model; block producers use a flexible concurrency protocol, while full nodes employ stateless validation to maximize parallel speedups. For network synchronization, MegaETH features a custom peer-to-peer protocol with compression techniques that allow even nodes with limited bandwidth to stay in sync at high throughput.

Polkadot is a blockchain network being built to enable Web 3.0, a decentralized and fair internet where users control their own data and markets prosper from network efficiency and security. Polkadot was founded in 2016 by Gavin Wood, former Co-Founder and CTO of Ethereum. Polkadot’s technology addresses the major issues that have stymied blockchain adoption in recent years. Polkadot’s software development toolkit, Substrate, created by Parity Technologies, makes it easy for blockchain developers to build their own custom, fit-for-use blockchains. Polkadot also enables multiple blockchains to communicate between each other, allows for easy upgradeability, and introduces “shared security”, a plug-and-play network security model that allows developers to focus on the technology and avoid spending time and resources recruiting a set of operators to run a new blockchain.

By applying optimistic rollup, we can achieve more than 5,000 TPS while keeping the gas prices as low as 0.000000008 Gwei. COMBO has built full-fledged partnerships with leading Web3 infrastructure projects to provide comprehensive development toolchains and built-in game engines.

The Raiden Network is an off-chain scaling solution, enabling near-instant, low-fee and scalable payments. It’s complementary to the Ethereum blockchain and works with any ERC20 compatible token. The Raiden project is work in progress. Its goal is to research state channel technology, define protocols and develop reference implementations. The Raiden Network is an infrastructure layer on top of the Ethereum blockchain. While the basic idea is simple, the underlying protocol is quite complex and the implementation non-trivial. Nonetheless the technicalities can be abstracted away, such that developers can interface with a rather simple API to build scalable decentralized applications based on the Raiden Network. The basic idea of the Raiden Network is to avoid the blockchain consensus bottleneck. This is done by leveraging a network of payment channels which allow to securely transfer value off-chain, i.e without involving the blockchain for every transfer.

Perun is an off-chain framework that supports real-time payments as well as complex business logic and supercharges any existing blockchain. Perun connects people across multiple blockchains, allowing interoperability between different currencies and blockchain networks. Transactions are instant, energy efficient and cheap to enable massively increased throughput by applying Layer-2-Technology. Virtual channel technology can keep your transaction data private and is continually proven secure to guarantee state-of-the-art procedures. Perun supports payments over NFC and Bluetooth without an active internet connection. The first component of Perun’s off-chain framework are State Channels. State Channels allow users to execute massive amounts transactions off-chain, while the security is backed by the underlying blockchain. The soundness of our protocols has been analyzed with cutting edge methods of cryptographic research.

The only Ethereum L2 with native yield for ETH and stablecoins. Blast yield comes from ETH staking and RWA protocols. The yield from these decentralized protocols is passed back to Blast users automatically. The default interest rate on other L2s is 0%. Our goal as contributors is to grow the on-chain economy with the highest-yield L2 possible. Community members who join our mission will have the opportunity to earn the Blast Airdrop. Blast only became possible this year following Ethereum's Shanghai upgrade. ETH yield from L1 staking, initially Lido, is automatically transferred to users via rebasing ETH on the L2.

opBNB is a high-performance layer-2 solution within the BNB ecosystem, built using the OP stack. Leveraging its block size of 100M, opBNB's gas fees remain stable and low cost, making it a great solution for widespread adoption across multiple digital environments. From gaming and decentralized exchanges to daily use and digital collectibles, opBNB caters to a diverse set of needs while delivering optimal performance. Gamers typically demand highly responsive experiences, for example, imagine looting an in-game asset after completing a combat scenario, but then having to wait dozens of seconds or even minutes for the game to respond and grant you the item. An experience like that would make the game largely unappealing and frustrating to play.

Dogechain supercharges $Dogecoin to bring crypto applications like NFTs, games, and DeFi to the $Dogecoin community. $Dogecoin has very limited access to these applications (or any other dApps) - Dogechain fixes this. With Dogechain, Dogecoin holders can do more than simply hodl and wait for Dogecoin to moon. Dogechain users can use $Dogecoin for gas fees. Dogechain brings utility to Dogecoin users tired of simply hodling $Dogecoin. The blockchain uses POS consensus to provide cheap fees and fast transactions.
