Many distributed ledgers have adopted this approach to increase their performance, however, they focus on the permissionless setting that assumes the existence of a strong adversary. In this paper, we deploy channels for permissioned blockchains. Our first contribution is to adapt sharding on asset-management applications for the permissioned setting, while preserving liveness and safety even on transactions spanning across-channels. Our second contribution is to leverage channels as a confidentiality boundary, enabling different organizations and consortia to preserve their privacy within their channels and still be part of a bigger collaborative ecosystem. To make our system concrete we map it on top of Hyperledger Fabric.","lang":"eng"}],"doi":"10.1007/978-3-319-99073-6_6","publisher":"Springer Nature","intvolume":"     11098","title":"Channels: Horizontal scaling and confidentiality on permissioned blockchains","author":[{"full_name":"Androulaki, Elli","first_name":"Elli","last_name":"Androulaki"},{"full_name":"Cachin, Christian","first_name":"Christian","last_name":"Cachin"},{"first_name":"Angelo","full_name":"De Caro, Angelo","last_name":"De Caro"},{"full_name":"Kokoris Kogias, Eleftherios","first_name":"Eleftherios","id":"f5983044-d7ef-11ea-ac6d-fd1430a26d30","last_name":"Kokoris Kogias"}],"publication_status":"published","day":"08","article_processing_charge":"No","language":[{"iso":"eng"}],"date_published":"2018-08-08T00:00:00Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2020-08-26T11:47:34Z","page":"111-131","oa_version":"None","citation":{"mla":"Androulaki, Elli, et al. “Channels: Horizontal Scaling and Confidentiality on Permissioned Blockchains.” <i>Computer Security</i>, vol. 11098, Springer Nature, 2018, pp. 111–31, doi:<a href=\"https://doi.org/10.1007/978-3-319-99073-6_6\">10.1007/978-3-319-99073-6_6</a>.","ieee":"E.
