Best Layer 2 Protocols in Germany

Meter is a high performance infrastructure that allows smart contracts to scale and travel seamlessly through heterogeneous blockchain networks. Meter is a Layer 1 and Layer 2 blockchain protocol. The Meter system consists of two tokens: MTRG, the governance token (eMTRG is the ERC20 version), and MTR, the low-volatility currency token. Financial assets should flow freely among blockchains. Meter’s HotStuff-based consensus allows 1000s of validator nodes, making Meter the most decentralized Layer 2 for Ethereum. Meter processes thousands of transactions per second and transactions are confirmed almost instantly. Meter Passport allows assets and smart contracts travel and communicate across heterogeneous blockchains for the best price, liquidity and yield. Meter is an Ethereum Compatible with unique enhancements. Unlike other Layer 2, DEXes build on Meter are front running/MEV resistant, fast and uncensorable.

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.

Loopring is an open protocol for building scalable non-custodial exchanges on Ethereum. Leveraging zero-knowledge proofs (zkRollup), it allows for high performance trading (high throughput, low settlement cost), without sacrificing Ethereum-level security guarantees. Users always maintain 100% control of their assets throughout the trade lifecycle. You can trade on Loopring to test it out. Loopring is an open-sourced, audited, and non-custodial exchange protocol, which means nobody in the Loopring ecosystem needs to trust others. Cryptoassets are always under users' own control, with 100% Ethereum-level security guarantees. Loopring powers highly scalable decentralized exchanges by batch-processing thousands of requests off-chain, with verifiably correct execution via ZKPs. The performance of underlying blockchains is no longer the bottleneck. Loopring performs most operations, including order-matching and trade settlement, off the Ethereum blockchain.

An open source community dedicated to scaling Bitcoin, especially its proof-of-work security, to meet global needs and emerging use cases, while sticking as close as possible to Bitcoin's original ideals. Syscoin's evolution across ten years of main net and the foresight reflected in its design means the project has a head-start providing a comprehensive network and protocol for projects aiming to achieve Bitcoin L2. Syscoin is a mainnet Bitcoin L2 that provides a data availability protocol that scales, making EVM and AltVM rollups on Bitcoin a reality. Merge-mined by a majority of Bitcoin's hash rate, Syscoin anchors rollups to Bitcoin's own proof-of-work and works with rollups’ existing sequencer architectures. Syscoin provides Bitcoin with a scalable data availability layer which is necessary for rollups (and other EVM or AltVM layers) to tap into Bitcoin's network in a safe and scalable way.

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.

Faster, more confidential Bitcoin transactions. Liquid is a sidechain-based settlement network for traders and exchanges, enabling faster, more confidential Bitcoin transactions and the issuance of digital assets. Bitcoin transfers on Liquid are fully settled within two minutes, allowing traders to move funds rapidly between exchanges and their own wallets without facing long, uncertain confirmation times. Anyone can issue new assets on Liquid, including stablecoins and security tokens. Each asset can be traded freely within the network, taking advantage of Liquid’s privacy, speed, and secure trading features. Asset types and amounts are hidden by default on the Liquid sidechain, keeping traders’ sensitive financial data secure from third parties, and preventing the front-running of large orders. Each asset on Liquid can be swapped for any other asset using the open source Liquid Swaps Tool.

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.
