Spectre A Fast And Scalable Cryptocurrency Protocol

Spectre a fast and scalable cryptocurrency protocol

In this paper we present SPECTRE, a PoW-based protocol that can process a high throughput of transactions and maintain fast confirmation times while remaining secure from attackers with up to 50% of the computational power. SPECTRE relies on a data structure that generalizes Nakamoto’s blockchain into a direct acyclic graph (a block DAG).

· We present SPECTRE, a new protocol for the consensus core of cryptocurrencies that remains secure even under high throughput and fast confirmation times.

At any throughput, SPECTRE is resilient to attackers with up to 50\% of the computational power (up until the limit defined by network congestion and bandwidth constraints). One of the big issues with bitcoin’s blockchain is the scalability of the protocol which means that the blockchain cannot process a high transaction.

SPECTRE: A Fast and Scalable Cryptocurrency Protocol [pdf let me get this right: you're proposing a new cryptocurrency, which the media and masses often unfairly associate with nefarious use cases, and the name you chose for it coincides with the nefarious criminal organization from the James Bond universe? wslh days ago.

Spectre: A fast and scalable distributed ledger protocol ...

Distributed cryptographic protocols such as Bitcoin and Ethereum use a data structure known as the block chain to synchronize a global log of events between nodes in their network. Blocks, which are batches of updates to the log, reference the parent they are extending, and thus form the structure of a chain.

Blockchain mining should not be a game among power oligarchs. In this paper, we present the Multiple Winners Proof of Work Protocol (MWPoW), a mining-pool-like decentralised blockchain consensus protocol. MWPoW enables disadvantaged nodes which post only a small amount of calculation resource in the mining game to create blocks together and compete with power oligarchs without centralised.
