Gönczy: Summer internship at the Linux Foundation mentor On-chain Business Process Management Course: Blockchain technologies and applications (coming next spring) Linux Foundation Hyperledger fabric: performance characterization and modelling Cooperation: Prof. Miklós Telek Dept. of Networked Systems and Services (HIT) 2

3 A new approach to business transactions Centralized Blockchain-based ledger Trusted 3 rd party Shared, distributed ledger 3

4 Blockchain, smart contracts [1] Source: Marley Gray, Principle Architect PM Microsoft: Introducing Project Bletchley 4

5 Properties Ledger: immutable Tx log; not (just) cryptocurrency! Smart contracts: programmed Tx logic over ledger state Shared: across participants Distributed: replication Cryptographically authentic: non-repudiable (secure identities), tokenization, signed Txs Trust: fault/attack tolerant group consensus 5

6 Basic transaction logic Client request Order, contract exec result, acceptance: consensus All ledgers updated Batch processing < Blockchain latency < hard real-time 6

7 An emerging sector Enterprise, permissioned Open/permissionless, cryptocurrency 7
