Alberto Garoffolo, Robert Viglione

TL;DR
This paper introduces a new sidechain design enabling secure, decentralized cross-chain transfers without mainchain node tracking, applicable to Horizen and similar blockchain systems.
Contribution
It presents a novel sidechain construction that allows secure cross-chain transfers without mainchain node verification, enhancing blockchain interoperability.
Findings
Secure cross-ledger transfer mechanism demonstrated
Compatible with Horizen blockchain and similar systems
Does not require mainchain nodes to track sidechains
Abstract
We propose a novel sidechain construction tailored to be compatible with the Horizen blockchain and designed for conducting secure and decentralized cross-chain transfers without requiring the mainchain nodes to track sidechains to verify them. The proposed scheme can also be adopted for other similar blockchain systems. We show that our cross-ledger transfer mechanism is secure under certain plausible assumptions.
