Oracles x Clarity Solutions


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 the launch on Stacks 2.0 main net. 
(For more information on smart contracts, check out my previous post DeFiOnBTC)

Chainlink is a decentralised oracle network that provides real work data to smart contracts on the blockchain. This will allow developers to build more advanced applications as they are able to avoid manipulation that are triggered by the smart contract, as well as to deliver high quality data for building the smart contract infrastructure, and end- to- end security.

The oracle contract will deliver high quality data  that needs to be easily useable for developers to pass and receive data beyond the blockchain platform delivering:


Developers will benefit from this with the following:
  • Access to Any API: Chainlink will allow developers to access off-chain API such as  password-protected data, and credentialed enterprise systems
  • Secure network infrastructure: Oracle services will benefit Blockstack’s applications by using Chainlink’s Sybil resistant node in relation to the decentralised oracle design.
  • Flexible Oracle Framework: Chainlink’s oracle solution is ready for production in market prices and verifiable randomness, building tool that can be customised by using the oracle design. 



Overall,  the collaboration between Blockstack and Chainlink will leverage and strengthen STX ecosystem’s security and infrastructure. Furthermore this  will support developers as a translator of information, allowing reliable data for real life events with the strength of Oracles that will provide smart contracts with necessary information off-chain -outside of the blockchain environment.

What is Proof- of-Transfer and Stacking?

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

My Top 3 Blockchain Projects

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

What Is Freehold?

Image
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. Contributing to the decentralised web.  Members of freehold are contributing to the STX
