Blockchain Glossary

Blockchain

blockchain
Blockchain technology is the use of cryptography to link data. It is basically a list of records that is unalterable. Along with this, it is also decentralized meaning it is not in the control of a single entity and is distributed among several entities to divide the power. In order to link the data is linked through a process known as “cryptographic hashing”. It uses a mathematical algorithm to map the data of arbitrary size to a fixed size.

Blockchain Business Models

The emergence of the Blockchain has also favored the development of new business models. It is essential to understand the implication of these new business models from a different standpoint. According to Joel Monegro, from 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, where the apps built on top of it will have a fraction of the value.

Blockchain Economics

According to Joel Monegro, 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!

Ethereum Blockchain

ethereum-blockchain
Ethereum is a cryptocurrency currently ranking at number two in market capitalization after Bitcoin, which is at the top. However, in terms of being used actively, Ethereum is ahead of Bitcoin. While Bitcoin is sent, received, and held only in a singular form, Ethereum allows entities to create different ledgers. These can even be used to create additional cryptocurrencies. The use and transactions using Ethereum have grown consistently over the years ever since it began operations half a decade ago.

Smart Contracts

smart-contracts
Smart contracts are protocols designed to facilitate, verify, or enforce digital contracts without the need for a credible third party. These contracts work on an “if/when-then” principle and have some similarities to modern escrow services but without a third party involved in guaranteeing the transaction. Instead, it uses blockchain technology to verify the information and increase trust between the transaction participants.

Stablecoins

stablecoins
Stablecoins are a type of cryptocurrency whose value is tied to an external asset to reduce volatility. Therefore, the value of a stablecoin is linked to the much more stable value of fiat currency – or government-issued currency such as dollars or euros. Thus, reducing the price volatility of the cryptocurrency to make it more appealing for transactions.

Decentralized Finance

decentralized-finance-defi
Decentralized finance (DeFi) refers to an ecosystem of financial products that do not rely on traditional financial intermediaries such as banks and exchanges. Central to the success of decentralized finance is smart contracts, which are deployed on Ethereum (contracts that two parties can deploy without an intermediary). DeFi also gave rise to dApps (decentralized apps), giving developers the ability to build applications on top of the Ethereum blockchain.

Non-fungible Tokens

non-fungible-tokens
Non-fungible tokens (NFTs) are cryptographic tokens that represent something unique. Non-fungible assets are those that are not mutually interchangeable. Non-fungible tokens contain identifying information that makes them unique. Unlike Bitcoin – which has a supply of 21 million identical coins – they cannot be exchanged like for like.

Proof of Work

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.

Proof of Stake

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.
