<p>Built on Optimism’s software package known as <a href="https://crypto.news/optimism-to-introduce-op-stack-to-resolve-human-coordination-issues/" data-type="link" data-id="https://crypto.news/optimism-to-introduce-op-stack-to-resolve-human-coordination-issues/" rel="noopener noreferrer nofollow">OP Stack</a>, opBNB is a layer-2 scaling solution engineered to accelerate transaction speeds and diminish fees for dapps. </p> 
<p>The technology allows for the deployment of Ethereum(ETH)-compatible dapps on an off-chain layer, subsequently securing these transactions through the BNB Chain using optimistic rollup technology.</p> 
<p>This architecture aims to resolve some of the longstanding issues surrounding blockchain scalability and cost, making the technology more accessible and functional for developers and users alike.</p>

<p>Arno Bauer, Senior Solution Architect at BNB Chain, emphasized that both scalability and security were of utmost importance throughout the development process. “Before opening the mainnet to the general public, strict criteria were met,” Bauer stated, highlighting the platform’s unwavering focus on performance and security metrics.</p>
