Towards Scaling Blockchain Systems via Sharding
TL;DR: In this article, the authors proposed a principled approach to apply sharding to blockchain systems in order to improve their transaction throughput at scale, which is challenging due to the fundamental difference in failure models between databases and blockchain.

Consensus in the Age of Blockchains.
Shehar Bano,Alberto Sonnino,Mustafa Al-Bassam,Sarah Azouvi,Patrick McCorry,Sarah Meiklejohn,George Danezis +6 more
TL;DR: A systematic and comprehensive study of blockchain consensus protocols is conducted, developing a framework to evaluate their performance, security and design properties, and using it to systematize key themes in the protocol categories described above.

Towards Scaling Blockchain Systems via Sharding
TL;DR: This work takes a principled approach to apply sharding to blockchain systems in order to improve their transaction throughput at scale, and achieves a high throughput that can handle Visa-level workloads, and is the largest ever reported in a realistic environment.

Short Signatures from the Weil Pairing
Dan Boneh,Ben Lynn,Hovav Shacham +2 more
TL;DR: A short signature scheme based on the Computational Diffie-Hellman assumption on certain elliptic and hyperelliptic curves is introduced, designed for systems where signatures are typed in by a human or signatures are sent over a low-bandwidth channel.
Journal ArticleDOI
Efficient signature generation by smart cards
TL;DR: An efficient algorithm that preprocesses the exponentiation of a random residue modulo p is presented, which improves the ElGamal signature scheme in the speed of the procedures for the generation and the verification of signatures and also in the bit length of signatures.
Ethereum: A Secure Decentralised Generalised Transaction Ledger
TL;DR: Ethereum as mentioned in this paper is a transactional singleton machine with shared state, which can be seen as a simple application on a decentralised, but singleton, compute resource, and it provides a plurality of resources, each with a distinct state and operating code but able to interact through a message-passing framework with others.

Ouroboros: A Provably Secure Proof-of-Stake Blockchain Protocol
TL;DR: “Ouroboros” is presented, the first blockchain protocol based on proof of stake with rigorous security guarantees and it is proved that, given this mechanism, honest behavior is an approximate Nash equilibrium, thus neutralizing attacks such as selfish mining.

A Secure Sharding Protocol For Open Blockchains
TL;DR: ELASTICO is the first candidate for a secure sharding protocol with presence of byzantine adversaries, and scalability experiments on Amazon EC2 with up to $1, 600$ nodes confirm ELASTICO's theoretical scaling properties.
