Oracle is a Greek Mythology for a priest or priestess acting as a medium to predict the future. The same terminology works with Blockchain Oracles to help make decisions for developers. Blockchain platforms such as Bitcoin does not have  available information outside of the chain,  thus makes it difficult to validate the conditions of the smart contracts.  The importance of oracles is that it allows smart contracts to interact with data outside of the blockchain environment. This provides necessary information for smart contracts to execute the original terms to meet the conditions of the contract. However, without access to sources of information, the use cases of smart contract will lose a portion of their potential to work.  Therefore, Oracle will leverage Blockstack’s smart contract language Clarity on Stacks 2.0.  Blockstack PBC and Chainlink Blockstack and Chainlink announced that they are collaborating to integrate oracles to Clarity- the smart contract language, leading up to t

Introduction  Cryptocurrencies are gradually moving towards a new generation of how transaction can make a real impact in current societies. In today’s post, I want to share with you my three favourite crypto projects and why I am inspired by them.   These are the projects: Lev Market Pilot Study  Risidio Auctions  The Fabricant 1. Bancor-  Lev Market Pilot Study  Galia Benartzi is the co- founder of Bancor. The Bancor Protocol Foundation promotes the development and the use of smart tokens through their smart contracts.  Galia mentioned in a talk that ‘money is a story’, that humans have created  value and meaning through money. In order to take this a step further and create a positive step for communities, Galia wanted to redesign the way people percieve and share the value of money on blockchain based assets, using tokens. Tokens are an incentive to encourage collective activity through community transactions, using the cryptocurrency ‘Hearts’. This is known as the Lev Market pilot

The Freehold community recognised that people are hodling but are not doing anything further to increase the value and mission of the token. Just like the fiat market, the cryptocurrency market also experiences volatility, however, the difference is that  people are not spending cryptocurrencies like money and are just holding onto it.  Freehold aims to revolutionise how users interact with each other to create a positive movement of crypto civilisation. Freehold believes that there is an opportunity to empower individuals and to grow through education, especially for people who may be skeptical about emerging technologies such as blockchain applications. Conversely, the developer community has done this by educating their communities by working collaboratively on platforms such as Github; including developing ideas, making clear on how to educate each other, and what is being done in open projects.

What is Decentralised Finance (DeFi)? Decentralised finance (DeFi) is well known in sectors such as finance and business within the crypto space. As mentioned in the previous post ‘What is Proof- of – Transfer and Stacking?’, the features of blockchain is the same mechanism used to secure the cryptocurrency bitcoin. DeFi stores existing financial assets such as loans, savings and investments into blockchain with the implementation of smart contracts. Smart contracts  eliminates the need or trust of a middle man or corporation to make the arrangements of personal assets (I will further explain this is more depth later on). On the contrary, centralised finance (CeFi) has a co-dependant relationship between government control and our  assets. If DeFi fails, it would become CeFi, thus defeating the purpose of decentralisation.  What makes DeFi desirable is the model of transparency, efficiency and most importantly security of personal assets. Bitcoin the digital currency is kept on a publi

Introduction Blockchain is a digital record that keeps track of all transactions and information that are made by an individual. This mechanism was unused until 2009 by Satoshi who created the digital cryptocurrency Bitcoin. Bitcoin is the most secure, trusted mechanism in processing electronic payments.   Blockchain is a distributed leger that is open to anyone. Data is    stored in blockchains called ‘blocks’, these blocks consists of    three features; 1.       Data – details of the transaction or information  2.       Hash-   this is equivalent to an ID that is unique to you 3.       Hash of previous block- connects the blocks together to create the chain   It is difficult for data    to be changed or tampered with once secured in a block. Inputted data creates a new block allowing transparency of information and prevents people from tampering the blocks. Nevertheless, there are still risks of tampering that can occur. To overcome this, blockchain uses a mechanisms called consensus
