Paper of the Week:
Paper Title: Proof-of-Burn.
Proof-of-burn has been used as a mechanism to destroy cryptocurrency in a verifiable manner and has not been previously formally studied as a primitive.
This work introduces proof-of-burn as a cryptographic primitive for the first time and defines it as a protocol which consists of two algorithms: (i) a burn address generator and (ii) a burn address verifier.
While performing the study, foundational properties such as unspendability, binding, and uncensorability are considered.
Next, a novel and simple construction which is flexible and can be adapted for use in existing cryptocurrencies is presented.
This construction is proven secure in the Random Oracle and requires cryptocurrencies to use public key hashes for address generation.
Following that, a cryptocurrency proof-of-burn bootstrapping mechanism is presented that does not require miners to connect to external blockchain networks.
This work is validated through a comprehensively tested production grade implementation of the bootstrapping mechanism in Ethereum written in Solidity, which is also available as open source software.
In addition, experimental measurements for the cost of burn verification are presented in current Ethereum prices showing that burn verification costs $0.28 per transaction.

“Significant research in the blockchain space is constantly being achieved by academic researchers. Unfortunately, a lot of this research is overlooked due to the massive numbers of papers being generated and the way they are being promoted and published. We’ve put together a categorized list of academic papers that can guide our subscribers and keep them up to date.”
