Tokenomics is an international forum for theory, design, analysis, implementation and applications of blockchains and smart contracts. The goal of the conference is to bring together economists, computer science researchers and practitioners working on blockchains in a unique program featuring ...

This paper studies how transaction fees and seigniorage, equivalent to inflation in the cryptocurrency setting, affect miner incentives and trade congestion. Each cryptocurrency miner chooses how many new transactions to group into the next block of transactions that the miner ...

In STARK-like zero -knowledge proofs, like those of the Starware company, the major algorithmic and mathematical breakthrough which enables such great performance in applications is the invention of very efficient "low degree test" of univariate polynomials. Our work enables to ...

Multi-client functional encryption (MCFE) is an extension of functional encryption (FE) in which the decryption procedure involves ciphertexts from multiple parties. In this paper, we consider MCFE schemes supporting encryption labels, which allow the encryptor to limit the amount of ...

In this paper, we present a multi-client quadratic functional encryption (MCQFE) scheme from function-hiding inner-product (FHIP). The main challenge in such construction is that all the clients require the access to the master secret key of the underlying FHIP scheme, ...

We propose a framework for the fundamental valuation of utility tokens. Our model endogenizes the velocity of circulation of tokens and yields a pricing formula that is fully microfounded. According to our model, tokens are valuable because they have to ...

It is widely believed that financial markets cannot be liquid without centralised processes to manage counterparty risk. We propose an alternative method for liquidity based on reversible and composable contracts run atop a blockchain. Novel instruments for zero-collateral intermediation can ...

A double-authentication preventing signature(DAPS)scheme is a digital signature scheme equipped with a self-enforcement mechanism. Messages consist of an address and a payload component, and a signer is penalized if she signs two messages with the same addresses but different payloads. ...
