PPCoin: Peer-to-Peer Crypto-Currency with Proof-of-Stake

  title={PPCoin: Peer-to-Peer Crypto-Currency with Proof-of-Stake},
  author={Sunny King and Scott Nadal},
A peer-to-peer crypto-currency design derived from Satoshi Nakamoto’s Bitcoin. Proof-of-stake replaces proof-of-work to provide most of the network security. Under this hybrid design proof-of-work mainly provides initial minting and is largely non-essential in the long run. Security level of the network is not dependent on energy consumption in the long term thus providing an energyefficient and more cost-competitive peer-to-peer crypto-currency. Proof-of-stake is based on coin age and… 

Bitcoin Wallet Transaction using Peer-to-Peer Network

A peer–to-peer allows online payments that sent directly from one party to another party without going through the financial institution. Digital signature is a part but the main benefit is lost, if

Bitcoin Cooperative Proof-of-Stake

A hard-fork reconfiguration of the peer to peer Bitcoin network is described that substitutes tamper-evident logs and proof- of-stake consensus for proof-of-work consensus and enables the processing of numerous microtransactions.

NeuCoin: The First Secure, Cost-Efficient and Decentralized Cryptocurrency

This paper demonstrates how NeuCoin’s proof-of-stake implementation addresses all commonly raised “nothing at stake” objections to generic proof- of-Stake systems, and reviews many of the flaws of proof-Of-work designs to highlight the potential for an alternate cryptocurrency that solves these flaws.

Formal Barriers to Longest-Chain Proof-of-Stake Protocols

The main results of this paper are several formal barriers to designing incentive-compatible proof-of-stake cryptocurrencies (that don't apply to proof- of-work).

KopperCoin - A Distributed File Storage with Financial Incentives

KopperCoin is a token system inspired by Bitcoin’s blockchain which can be integrated into a peer-to-peer file storage system and provides direct reward to participants contributing storage resources.

Designing Proof of Transaction Puzzles for Cryptocurrency

A novel Proof of Transaction (PoT) puzzle is constructed, and it is proved that PoT puzzle satisfies the basic construction conditions of scratch-off puzzle, and construction of PoTcoin is shown as application.

Myth, machinery and cryptocoin avarice

This paper aims to address the questions like « to whom do the structures like Bitcoin ultimately serve ? » and to propose an idea that further growth of cryptocoin economy could induce a sort of Nietzche’s «transvaluation of values».

Winkle: Foiling Long-Range Attacks in Proof-of-Stake Systems

It is shown that under plausible and flexible security assumptions about clients the confirmed checkpoints can not be equivocated, and checkpoint latency is evaluated experimentally using Bitcoin and Ethereum transaction graphs, with and without delegation of stake.

Comparative evaluation of consensus mechanisms in cryptocurrencies

A comparative evaluation that has been conducted on various significant consensus mechanisms used by other cryptocurrencies is presented, highlighting the unique characteristics, as well as drawbacks, of each mechanism.

Pikachu: Securing PoS Blockchains from Long-Range Attacks by Checkpointing into Bitcoin PoW using Taproot

This work uses Schnorr signatures and leverages Bitcoin recent Taproot upgrade, allowing it to create a checkpointing transaction of constant size and argues for the security of the protocol and presents an open-source implementation that was tested on the Bitcoin testnet.


On bitcoin and red balloons

This work examines a common scenario in which only participants that are aware of the information can compete for some reward, and thus informed participants have an incentive not to propagate information to others, and proposes a modification to the protocol that can eliminate this problem.
