Solidity Tutorial

What is solidity in a blockchain? Solidity is a contract-oriented,   high level programming language.Solidity designed to target Ethereum Virtual Machine (EVM). What is Smart Contracts in blockchain? A smart contract is computer protocol business logic.

Blockchain in Government and the Public Sector : Why Governments Need Blockchain

 Most government and public sectors leverage blockchain technology to move away from siloed and inefficient centralized system.Blockchain networks offer unbreakable security, agile and cost-effective infrastructure as compare to inherently insecure and high-cost systems.
Although , Blockchain technologies are fascinating improvement and anti-corruption communities because of their power to prevent corruption and guard public registries against fraud.

Every country in the world,governmental administrative systems based on classical centralized,hierarchical system.We're live in the digital high-speed world and classical systems is outdated.Few organizations are updating traditional system to highly effective and secured blockchain system.First-generation online e-Goverment systems are easily hacked and prone to fraudsters because of highly-centralized databases and insecure data sharing.

“Thanks to blockchain-based digital identities, people are getting back control over their own data.”​ – Martin Würmli, Zug Head Municipal Clerk

Advantages of having a blockchain-based government system

  • Tracking Vaccinations
  • Highly Secure storage of government,citizen and business data.
  • Decreases potential for corruption to every sectors.
  • Increases trust in data/code and transparency in e-Goverment systems.
  • Decreases of costs with managing accountability.
  • The distributed ledger format can support digital currency(e-rupee,etc),land registration,supply-chain traceability, heal sector, taxation, voting(immutable votes) and legal corporate registrations.
  • Validation of Education and Professional Qualifications

Blockchain Explained: A Quick Overview

Blockchain technology is most simply defined as a decentralized, distributed ledger technology (DLT) that records the provenance of a digital asset.Blockchain technology may be a new, powerful tool that's already shaping the longer term of the web with simple, safe and secure transactions.

  • A blockchain is a database that stores encrypted blocks of data then chains them together to form a chronological single-source-of-truth for the data
  • Digital assets are distributed instead of copied or transferred, creating an immutable record of an asset
  • The asset is decentralized, allowing full real-time access and transparency to the public
  • A transparent ledger of changes preserves integrity of the document, which creates trust in the asset.

Some Countries Accelerating Blockchain Innovation

  • Smart Dubai : Using blockchain to forge a seamless city experience in the UAE.In line with Smart Dubai’s mandate to become global leader in the smart economy, fueling entrepreneurship and global competitiveness.
  • Self Sovereign Identity for Government Services in Zug, Switzerland : Zug created their own identity on the public Ethereum network. Zug , sometimes referred to as “Crypto Valley” is well known as an inviting for blockchain businesses.AirBie “Crypto-E-Bikes” The two bike rental systems that have been in use in the city and canton since last year are being used extensively.
  • EU Blockchain Observatory & Forum : To create a transparent forum where all of Europe’s blockchain citizen can share experience, debate issues, and reflect on the future of this new technology.

Blockchain has the potential to be a game changer in anti-corruption efforts. Whether it's successful or not largely depends on contextual elements – infrastructures, legal systems, social or political settings – instead of on the technology itself.
