Modular zk-Rollup On-Demand
Thomas Lavaur, Jonathan Detchart, Jérôme Lacan +1
The rapid expansion of the use of blockchain-based systems often leads to a choice between customizable private blockchains and more secure, scalable and decentralized but expensiv…
Using Homomorphic hashes in coded blockchains
Doriane Perard, Xavier Goffin, Jérôme Lacan
One of the scalability issues of blockchains is the increase of their sizes which can prevent users from storing them and thus from contributing to the decentralization effort. Rec…
BlockHouse: Blockchain-based Distributed Storehouse System
Doriane Perard, Lucas Gicquel, Jérôme Lacan
We propose in this paper BlockHouse, a decentralized/P2P storage system fully based on private blockchains. Each participant can rent his unused storage in order to host data of ot…
XOR-based Source Routing
Jérôme Lacan, Emmanuel Lochin
We introduce a XOR-based source routing (XSR) scheme as a novel approach to enable fast forwarding and low-latency communications. XSR uses linear encoding operation to both 1)~bui…
Erasure code-based low storage blockchain node
Doriane Perard, Jérôme Lacan, Yann Bachy +1
The concept of a decentralized ledger usually implies that each node of a blockchain network stores the entire blockchain. However, in the case of popular blockchains, which each w…
Improving the coding speed of erasure codes with polynomial ring transforms
Jonathan Detchart, Jérôme Lacan
Erasure codes are widely used in today's storage systems to cope with failures. Most of them use the finite field arithmetic. In this paper, we propose an implementation and a codi…
