This is a very basic first Litepaper, serving as an initial guideline for interested developers. More information will be added as the project moves past the testing phases.
Scaling BNB Smart Chain (BSC) with the Autobahn L2
The Autobahn Network is a Layer2 Rollup created to support and scale the BNB Smart Chain (BSC; formerly known as Binance Smart Chain) network. Using Go Ethereum, the Autobahn was designed as a rollup to batch process transactions to reduce usage and cost on the BNB Smart Chain base layer. For the first time after launch, the Autobahn will run as its own network with 21 nodes (potentially less in the early days after launch) based on a Proof of Authority Consensus. It will step-by-step migrate to a zero knowledge powered solution (potentially based on ZkBNB).
The Autobahn is designed with developers and the community in mind with the goal of sustaining a seamless user experience in the BNB ecosystem. Marketing for the Autobahn Network will focus on the NFT community. The Autobahn Network uses its own gas token $TXL.
2021 was the year of Layer 1 (L1) blockchains. With the launch of each new blockchain, it became clear there was a need for other networks, as transaction costs on existing ones- such as Ethereum- began to increase and transaction speeds slowed down as block space demand grew. Additionally, multiple unforeseen use cases have arisen in crypto that are taking up more block space, such as NFTs and GameFi—making future demand unpredictable for any given chain.
Rollup scaling solutions were invented-such as Optimistic and Zero-Knowledge Rollups - to increase transaction volumes, reduce transaction times and minimize gas fees. However, these scaling solutions focused mainly on scaling Ethereum. The Autobahn Network developers saw the need for other EVM chains to have a scaling tool to prevent them from running into the same situation, hence the creation of the Autobahn Network.
The Autobahn Network is designed to serve the BNB Smart Chain (BSC) and its community. BSC has proven to be one of the highest throughput Layer 1s in terms of volume and new projects being built in the blockchain ecosystem. To enhance this growth and ensure that projects are not hindered by a slower and more expensive base layer, the Autobahn Network is launching before the BNB network becomes even more congested and expensive. Even today, the average BSC transaction already costs around $0.35 (Source: YCharts). This cost is not feasible for the many NFT and game projects with high transaction volumes. A transaction with the Autobahn Network L2 is expected to be 95% cheaper, at around $0.0175.
Autobahn Network’s Goal
To provide fast and straightforward scaling solutions to projects on BNB to keep gas costs low, and increase the productivity and longevity of the BNB Smart Chain base layer.
Autobahn Network’s Token
TXL = Transaction Lane, formerly known as “Tixl”.
TXL acts as the primary source of Gas when it comes to paying for transactions on the Autobahn Network. For further details on the TXL please see the Tokenomics section of the Gitbook.
