blockchain is a replicated, tamper-evident database designed for hostile environments. It consists of a number of nodes, of which some may be malicious, which maintain an append-only ledger. The ledger stores transactions that modify some global states. In the canonical example, i.e., cryptocurrencies , the global states are user accounts and native tokens, and the ledger contains transactions transferring tokens from one account to another.
with some of the most popular blockchain platforms that support smart contracts: Ethereum, Hyperledger Fabric, and Quorum. Finally, we have developed a GUI for our case study. The auction case study is one of three case studies whose code can be found in the PIEChain code repository on GitHub. II. OVERVIEW OF
has the same structure as cross-chain deals as proposed by Herlihy et al. . Cross-chain deals are agreements by multiple users to exchange assets on different blockchains, and consist of five phases : Clearing phase: the CC-SVC creates the smart contracts on the different blockchains that are used to escrow and transfer the assets involved in the deal. Escrow phase: the users escrow their outgoing assets by transferring them to the smart contracts.
, the auction requires two types of CC-SVC: the relayer and the signer. The relayer listens for events on the coin chains and relays them to the ticket blockchain. The signer assists in creating the commit vote. IV. Rafael Belchior, Andre Vasconcelos, S ´ ergio Guerreiro, and Miguel ´ Correia.
