Proof of Work vs. Proof of Stake In A Nutshell

Proof of Work and Proof of Stake are the two primary philosophies and consensus algorithms behind the Blockchain protocols, since the inception of Bitcoin. For instance, Bitcoin still runs through Proof of Work. While other protocols, like Ethereum moved toward Proof of Stake.

Proof of Stake in a nutshell

proof-of-stake
A Proof of Stake (PoS) is a form of consensus algorithm used to achieve agreement across a distributed network. As such it is, together with Proof of Work, among the key consensus algorithms for Blockchain protocols (like the Ethereum’s Casper protocol). Proof of Stake has the advantage of security, reduced risk of centralization, and energy efficiency.

Proof of Work in a nutshell

proof-of-work
A Proof of Work is a form of consensus algorithm used to achieve agreement across a distributed network. In a Proof of Work, miners compete to complete transactions on the network, by commuting hard mathematical problems (i.e. hashes functions) and as a result they get rewarded in coins.

Key takeaways

Consensus algorithms help Blockchain Protocols reach agreement among a distributed network. Among those consensus algorithm there are two main philosophies: Proof of Stake and Proof of Work.

The Proof of Stake determines the consensus based on the stake of each user in the network.

In a Proof of Work, miners compete to complete transactions on the network, by commuting hard mathematical problems (i.e. hashes functions) and as a result they get rewarded in coins.

According to Joel Monegro, a former analyst at USV (a venture capital firm) the blockchain implies value creation in its protocols. Where the web has allowed the value to be captured at the applications layer (take Facebook, Twitter, Google, and many others). In a Blockchain Economy, this value might be captured by the protocols at the base of the blockchain (for instance Bitcoin and Ethereum). However, according to blockchain investor Paivinen due to ease of forking, incentives to compete and improved interoperability and interchangeability also in a blockchain-based economy, protocols might get thinner. Although the marginal value of scale might be lower compared to a web-based economy, where massive scale created an economic advantage. The success of the Blockchain will depend on its commercial viability!

vbde-framework
A Blockchain Business Model according to the FourWeekMBA framework is made of four main components: Value Model (Core Philosophy, Core Values and Value Propositions for the key stakeholders), Blockchain Model (Protocol Rules, Network Shape and Applications Layer/Ecosystem), Distribution Model (the key channels amplifying the protocol and its communities), and the Economic Model (the dynamics/incentives through which protocol players make money). Those elements coming together can serve as the basis to build and analyze a solid Blockchain Business Model.
ethereum-blockchain
Ethereum was launched in 2015 with its cryptocurrency, Ether, as an open-source, blockchain-based, decentralized platform software. Smart contracts are enabled, and Distributed Applications (dApps) get built without downtime or third-party disturbance. It also helps developers build and publish applications as it is also a programming language running on a blockchain.
the-graph-token
The Graph is an ERC20 Utility Token (built on top of Ethereum) to enable consumers to freely query the blockchain through a fully decentralized database kept by indexers, incentivized by the payment of tokens (called GRT). The network is also ministered by curators and delegators that help maintain a high-quality index.
bat-token
BAT or Basic Attention Token is a utility token aiming to provide privacy-based web tools for advertisers and users to monetize attention on the web in a decentralized way via Blockchain-based technologies. Therefore, the BAT ecosystem moves around a browser (Brave), a privacy-based search engine (Brave Search), and a utility token (BAT). Users can opt-in to advertising, thus making money based on their attention to ads as they browse the web.
ripple-blockchain
In 2012, co-founders Christian Larsen and Jed McCaleb created Ripple, a technology acting as both a pre-mined cryptocurrency called XRP and a digital payment platform enabling monetary transactions. Where Ripple is the tech company, XRP is the decentralized ledger.
stellar-blockchain
In 2014, Jed McCaleb – which also played a key role in the development of Ripple – created a cryptocurrency to provide fast, reliable, and affordable money transactions. The same cryptocurrency has considerably grown seven years later. It is now one of the most stellar cryptocurrencies to provide a real-time platform that links banks, payment systems, and people. Meet, Stellar!
bittorrent-token
In early 2019, a joint project between TRON and BitTorrent Foundation called BitTorrent Token came to fruition. BitTorrent Token launched to tokenize in-demand file-sharing protocol and enhance content delivery and bandwidth accessibility with blockchain technology.
chainlink-token
Chainlink is considered the most established decentralized oracle network. As an ecosystem housing several decentralized oracle networks running simultaneously. As a decentralized oracle service built on Ethereum, Chainlink has the power to support the development of blockchain solutions for both traditional businesses and enterprises.
decentralized-exchange-platforms
Uniswap is a renowned decentralized crypto exchange created in 2018 and based on the Ethereum blockchain, to provide liquidity to the system. As a cryptocurrency exchange technology that operates on a decentralized basis. The Uniswap protocol inherited its namesake from the business that created it — Uniswap. Through smart contracts, the Uniswap protocol automates transactions between cryptocurrency tokens on the Ethereum blockchain.
polkadot-token
In essence, Polkadot is a cryptocurrency project created as an effort to transform and power a decentralized internet, Web 3.0, in the future. Polkadot is a decentralized platform, which makes it interoperable with other blockchains.
cardano-blockchain
Designed and created as an alternative to Ethereum, Cardano claims to be the first decentralized blockchain protocol to use a scientific approach and undergo a peer evaluation.
solana-blockchain
Solana is a blockchain network with a focus on high performance and rapid transactions. To boost speed, it employs a one-of-a-kind approach to transaction sequencing. Users can use SOL, the network’s native cryptocurrency, to cover transaction costs and engage with smart contracts.
