The Rosen<sup>1<\/sup> Bridge design will permit value to be transferred or directly from Bitcoin to Cardano for example, without needing to be converted to an intermediate token such as Ergo.<\/p>\n\n\n\n<p>Initial uptake looks very positive with the RSN token already showing a significant increase in price along with ERG, both of which are needed to operate watchers. There are already more than 80 watchers on Cardano and Ergo sides of the bridge which bodes well for a successful launch in the coming months.<\/p>\n\n\n\n<p>In the longer term Rosen Bridge has the potential to bring significant additional liquidity into the Cardano and Ergo ecosystems. It could also change the bridge landscape in time, assuming the implementation delivers the security and decentralisation benefits promised.<\/p>\n\n\n\n<p>More information is available from <a href=\"https:\/\/rosen.tech\">https:\/\/rosen.tech<\/a>.<\/p>\n\n\n\n<p><sup>1<\/sup> If you are curious where the name for the bridge comes from then check out <a href=\"https:\/\/en.wikipedia.org\/wiki\/Wormhole\">this article<\/a> on Wormholes.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>Einstein\u2013Rosen bridges, also known as&nbsp;<em>EPR=KOI bridges<\/em><sup><a href=\"https:\/\/en.wikipedia.org\/wiki\/Wormhole#cite_note-Dobrev-17\">[17]<\/a><\/sup>&nbsp;(named after&nbsp;<a href=\"https:\/\/en.wikipedia.org\/wiki\/Albert_Einstein\">Albert Einstein<\/a>&nbsp;and&nbsp;<a href=\"https:\/\/en.wikipedia.org\/wiki\/Nathan_Rosen\">Nathan Rosen<\/a>),<sup><a href=\"https:\/\/en.wikipedia.org\/wiki\/Wormhole#cite_note-ER-18\">[18]<\/a><\/sup>&nbsp;are connections between areas of space that can be modeled as&nbsp;<a href=\"https:\/\/en.wikipedia.org\/wiki\/Vacuum_solution\">vacuum solutions<\/a>&nbsp;to the&nbsp;<a href=\"https:\/\/en.wikipedia.org\/wiki\/Einstein_field_equations\">Einstein field equations<\/a>, and that are now understood to be intrinsic parts of the&nbsp;<a href=\"https:\/\/en.wikipedia.org\/wiki\/Kruskal%E2%80%93Szekeres_coordinates#The_maximally_extended_Schwarzschild_solution\">maximally extended<\/a>&nbsp;version of the&nbsp;<a href=\"https:\/\/en.wikipedia.org\/wiki\/Schwarzschild_metric\">Schwarzschild metric<\/a>&nbsp;describing an eternal black hole with no charge and no rotation.<\/p>\n<cite><a href=\"https:\/\/en.wikipedia.org\/wiki\/Wormhole\">https:\/\/en.wikipedia.org\/wiki\/Wormhole<\/a><\/cite><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>Bridges are an important part of the crypto landscape to provide liquidity and integration between crypto ecosystems such as Bitcoin, Ethereum and Cardano.
