An experimental evaluation of the scalability of permissioned blockchains

Permissioned blockchains are decentralized digital systems, which are used to record transactions and which maintain multiple, synchronized copies of the whole list of transactions (i.e., the ledger) on geographically dispersed nodes. Cryptographic operations are used to ‘chain’ transactions in the ledger, making the system tamper-resistant. In permissioned blockchains, access to the system (in pa...
