Incentivizing Blockchain Forks via Whale Transactions
Bitcoin’s core innovation is its solution to double-spending, called Nakamoto consensus. This mechanism provides a probabilistic guarantee that transactions will not be reversed once they are sufficiently deep in the blockchain, assuming an attacker controls a bounded fraction of mining power in the network. We show, however, that when miners are rational this guarantee can be undermined by a w...

But descriptions of many these proposals are more visionary projections than realizable proposals, and even basic definitions are often missing. We define “blockchain” and “blockchain network”, and then discuss two very different, well known classes of blockchain networks: cr...
متن کاملA Formal Framework for Policy Analysis
We present a formal, logical framework for the representation and analysis of an expressive class of authorization and obligation policies. Basic concepts of the language and operational model are given, and details of the representation are defined, with an attention to how different classes of policies can be written in our framework. We show how complex dependencies amonst policy rules can b...
