Best Layer 2 Protocols in Germany

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.

Liquidity is a significantly better account to manage your money and crypto coins better, wherever you are, whoever you are. Unlike banks, we can't freeze your money, we speak to our customers like humans, we don’t add hidden fees and we put technology and research at the heart of everything we do. User security is the priority, users are always in control of their funds. Liquidity Network's transaction throughput is not bound by the blockchain. Liquidity Network enables gasless transfers and swaps. Intuitive API for developers to build usable dApps. Based on peer-reviewed research, our work is publicly available, to introduce a secure and scalable solution to the community. Liquidity Network's smart contracts are completely open-source under GNU General Public License v3.0. LQD is the main utility token used to pay for Liquidity Network’s services. Think instant transfers, direct spending notifications, swapping cryptocurrencies and an easy way to spend and send to friends.

COMBO is a leading provider of scaling solutions for Web3 game development. By leveraging the world's top game engine, COMBO is building an open source, decentralized, game-oriented protocol that is accessible to everyone. It aims to maximize the potential of Web3 games by connecting game developers with the entire ecosystem in an efficient, affordable, and secure way. COMBO has built full-fledged partnerships with leading Web3 infrastructure projects to provide comprehensive development toolchains and built-in game engines. These advanced tools can help game developers to easily get into the Web3 world, and simplify and accelerate their game development process. 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.

Carbon is a cross-chain protocol that acts as a building block for DeFi. Carbon protocol allows anyone to bootstrap open financial markets for any asset type, on any blockchain. Carbon powers Demex, a popular, fully decentralized exchange for trading a plethora of financial instruments. Powers interoperability between blockchains like Ethereum, Cosmos, BSC, Neo and Zilliqa with true cross-chain liquidity pools through the PolyNetwork bridge. Supports any DeFi innovation with native support of crypto derivatives, Balancer-style liquidity pools, AMMs, on-chain order books and more. Custom-built using Cosmos-SDK and secured by a large network of validators through Tendermint PoS for trustless and safe transactions. Powers interoperability between blockchains like Ethereum, Cosmos, BSC, Neo and Zilliqa with true cross-chain liquidity pools through the PolyNetwork bridge.
