Avalanche is a layer one blockchain that functions as a platform for decentralized applications and custom blockchain networks. It is one of Ethereum’s rivals, aiming to unseat Ethereum as the most popular blockchain for smart contracts. It aims to do so by having a higher transaction output of up to 6,500 transactions per second while not compromising scalability.

This is made possible by Avalanche’s unique architecture. The Avalanche network consists of three individual blockchains: the X-Chain, C-Chain and P-Chain. Each chain has a distinct purpose, which is radically different from the approach Bitcoin and Ethereum use, namely having all nodes validate all transactions. Avalanche blockchains even use different consensus mechanisms based on their use cases.

After its mainnet launch in 2020, Avalanche has worked on developing its own ecosystem of DApps and DeFi. Different Ethereum-based projects such as SushiSwap and TrueUSD have integrated with Avalanche. Furthermore, the platform is constantly working on improving interoperability between its own ecosystem and Ethereum, like through the development of bridges.

Business & Consumer Applications

Avalanche accelerates blockchain business growth by enabling fast, scalable Web3 application development. The Avalanche network is a system of interconnected Layer 1 blockchains, linked through native Interchain Messaging. With built-in customizability and out-of-the-box tooling, projects on Avalanche can scale both up and across the network. Avalanche L1s offers tailored technology for real-world needs.

Web 3.0 Procurement. Polkadot Ecosystem

polkadot.com

polkadot.subscan.io

coinmarketcap.com

Polkadot is an open-source sharded multichain protocol that connects and secures a network of specialized blockchains, facilitating cross-chain transfer of any data or asset types, not just tokens, thereby allowing blockchains to be interoperable with each other. Polkadot was designed to provide a foundation for a decentralized internet of blockchains, also known as Web3.

Polkadot is known as a layer-0 metaprotocol because it underlies and describes a format for a network of layer 1 blockchains known as parachains (parallel chains). As a metaprotocol, Polkadot is also capable of autonomously and forklessly updating its own codebase via on-chain governance according to the will of its token holder community.

Polkadot provides a foundation to support a decentralized web, controlled by its users, and to simplify the creation of new applications, institutions and services.

The Polkadot protocol can connect public and private chains, permissionless networks, oracles and future technologies, allowing these independent blockchains to trustlessly share information and transactions through the Polkadot Relay Chain (explained further down).

Polkadot’s native DOT token serves three clear purposes: staking for operations and security, facilitating network governance, and bonding tokens to connect parachains .

Smart Contract

Polkadot offers developers flexibility in building smart contracts, supporting both Wasm-based contracts using ink! (written in Rust) and Solidity contracts executed by the EVM (Ethereum Virtual Machine).

  • Wasm (ink!) contracts – contracts are written in Rust and compiled to Wasm. The advantage of Wasm is that it allows for more flexibility, speed, and potentially lower execution costs compared to EVM, especially in the context of Polkadot’s multi-chain architecture
  • EVM-compatible contracts – contracts are written in languages like Solidity or Vyper and executed by the Ethereum Virtual Machine (EVM). The EVM is widely standardized across blockchains, including Polkadot parachains like Astar, Moonbeam, and Acala. This compatibility allows contracts to be deployed across multiple networks with minimal modifications, benefiting from a well-established, broad development ecosystem

Solana is a highly functional open source project that banks on blockchain technology’s permissionless nature to provide decentralized finance (DeFi) solutions. The Solana protocol is designed to facilitate decentralized app (DApp) creation. It aims to improve scalability by introducing a proof-of-history (PoH) consensus combined with the underlying proof-of-stake (PoS) consensus of the blockchain. Because of the innovative hybrid consensus model, Solana enjoys interest from small-time traders and institutional traders alike. A significant focus for the Solana Foundation is to make decentralized finance accessible on a larger scale.

Smart Contract

On Solana, “smart contracts” are called programs. Programs are deployed on-chain to accounts that contain the program’s compiled executable binary. Users interact with programs by sending transactions containing instructions that tell the program what to do.

Solana programs are predominantly written in the Rust programming language, with two common approaches for development:

Anchor: A framework designed for Solana program development. It provides a faster and simpler way to write programs, using Rust macros to reduce boilerplate code. For beginners, it is recommended to start with the Anchor framework.

Native Rust: This approach involves writing Solana programs in Rust without leveraging any frameworks. It offers more flexibility but comes with increased complexity.

Ethereum is a decentralized open-source blockchain system that features its own cryptocurrency, Ether. ETH works as a platform for numerous other cryptocurrencies, as well as for the execution of decentralized smart contracts.

Ethereum’s own purported goal is to become a global platform for decentralized applications, allowing users from all over the world to write and run software that is resistant to censorship, downtime and fraud.

DeFi

DeFi is an open and global financial system built for the internet age – an alternative to a system that’s opaque, tightly controlled, and held together by decades-old infrastructure and processes. It gives you control and visibility over your money. It gives you exposure to global markets and alternatives to your local currency or banking options. DeFi products open up financial services to anyone with an internet connection and they’re largely owned and maintained by their users. So far tens of billions of dollars worth of crypto has flowed through DeFi applications and it’s growing every day.

DAO

A DAO is a collectively-owned organization working towards a shared mission. DAOs allow us to work with like-minded folks around the globe without trusting a benevolent leader to manage the funds or operations. There is no CEO who can spend funds on a whim or CFO who can manipulate the books. Instead, blockchain-based rules baked into the code define how the organization works and how funds are spent. They have built-in treasuries that no one has the authority to access without the approval of the group. Decisions are governed by proposals and voting to ensure everyone in the organization has a voice, and everything happens transparently onchain.

Payments

While traditional financial institutions have built robust payment systems over decades, they often remain constrained by borders, working hours, and legacy infrastructure. Ethereum offers a new paradigm: a global, 24/7 financial platform that enables near-instant, programmable transactions for anyone with internet access.

Smart contract

A “smart contract” is simply a program that runs on the Ethereum blockchain. It’s a collection of code (its functions) and data (its state) that resides at a specific address on the Ethereum blockchain. Smart contracts are a type of Ethereum account. This means they have a balance and can be the target of transactions. However they’re not controlled by a user, instead they are deployed to the network and run as programmed. User accounts can then interact with a smart contract by submitting transactions that execute a function defined on the smart contract. Smart contracts can define rules, like a regular contract, and automatically enforce them via the code. Smart contracts cannot be deleted by default, and interactions with them are irreversible.

The two most active and maintained languages are:

Solidity

  • Object-oriented, high-level language for implementing smart contracts.
  • Curly-bracket language that has been most profoundly influenced by C++.
  • Statically typed (the type of a variable is known at compile time).
  • Supports: Inheritance, Libraries, Complex user-defined types.

Online Educational Course “e-Procurement Learning”

This e-Learning course is designed to provide participants with an in-depth understanding of the concept of public procurement and e-Government Procurement (e-GP) and how e-Procurement solutions can be designed and implemented in a more effective and economical way. This course outlines how to prepare a strategy for establishing an e-GP framework and presents in detail basic and advanced tools of e-Procurement systems. Moreover, it describes the need for the establishment and use of public procurement indicators, as well as how public financial management can be strengthened through the incorporation of procurement and e-Procurement into PFM reform projects.

Course overview

E-Government procurement (e-GP) projects are often part of the wider e-government efforts of countries to efficiently and effectively serve their citizens and businesses. E-GP promotes better governance in public procurement by increasing transparency and eliminating opportunities for fraud and corruption. The application of ICT to procurement processes has resulted in e-Procurement platforms that are ideally suited to address the e-GP objectives.

Pursuing an e-Procurement system implementation is an effective way to improve public procurement management, through the automation of all underlying processes. Many governments worldwide have adopted end-to-end e-Procurement systems which cover the full procurement cycle.

The current e-Learning course is composed of five modules, aiming to assist its audience to better understand electronic procurement and provide them with guidance on decisions they may need to take for establishing or improving the e-GP framework of their countries.

The course initially focuses on how organizations can establish a plan for an e-GP implementation, and what benefits can be expected by such an implementation project. Furthermore it provides an overview of the basic and advanced features and modules of e-Procurement systems, along with concise information on how to implement each of the described e-Procurement modules.

Additionally, the course briefly describes e-Procurement indicators and presents how these can be used by governments in order to measure adoption, performance and overall governance. Lastly, it focuses on how to incorporate procurement and e-procurement into FMIS implementations in the context of PFM reform projects.

At the end of this course, a certification can be obtained by those participants who complete the course and successfully pass the respective examination.
