Ecoterra is a blockchain ecosystem that was initiated on the 1st of April, in Bucharest, Romania, by a team experienced in recycling and business. It integrates several functionalities to engage individuals and businesses in actions that support climate change mitigation.

One function, the 'Recycle2Earn' (R2E) application, allows users to earn Ecoterra tokens when they recycle various materials, associating a certain amount of Ecoterra with each recyclable item. This app is a part of the ecosystem's effort to promote waste management and environmentally-conscious habits.

The ecosystem also includes a Carbon Offset Marketplace, a platform where users can use Ecoterra or other cryptocurrencies to counterbalance their carbon emissions by investing in carbon offset projects. This feature offers a direct connection between digital currencies and environmental impact mitigation.

Further, Ecoterra provides a Recycled Materials Marketplace where businesses can purchase recycled materials such as plastic, glass, and aluminum using Ecoterra or other cryptocurrencies. The aim is to support the use of recycled materials and encourage responsible consumption.

The fourth feature is the Impact Trackable Profile, a tool designed for individuals and businesses to record and display their environmentally friendly actions. This feature can help build an 'eco-portfolio', demonstrating a commitment to sustainability and potentially fostering customer loyalty.

In essence, Ecoterra is a blockchain ecosystem combining several features - the R2E app, the Carbon Offset and Recycled Materials Marketplaces, and the Impact Trackable Profile. This project, originating from Bucharest, Romania, represents an approach to align economic incentives with climate change mitigation actions, encouraging waste management, responsible consumption, and the use of recycled materials.

Kaspa is a proof-of-work (PoW) cryptocurrency which implements the GHOSTDAG protocol. Unlike traditional blockchains, GHOSTDAG does not orphan blocks created in parallel, rather allows them to coexist and orders them in consensus. The Kaspa blockchain is actually a blockDAG. This generalization of Nakamoto consensus allows for secure operation while maintaining very high block rates (currently one block per second, aiming for 10/sec, dreaming of 100/sec) and minuscule confirmation times dominated by internet latency.

The Kaspa implementation includes a lot of cool features such as Reachability to query the DAG's topology, Block data pruning (with near-future plans for block header pruning), SPV proofs, and later subnetwork support which will make future implementation of layer 2 solutions much easier.

Hedera is the most used, sustainable, enterprise-grade public network for the decentralized economy that allows individuals and businesses to create powerful decentralized applications (DApps).

It is designed to be a fairer, more efficient system that eliminates some of the limitations that older blockchain-based platforms face — such as slow performance and instability.

It was funded through an initial coin offering (ICO) in August 2018 and first launched open access to its mainnet just over a year later in September 2019. As part of the ICO, investors were able to purchase the platform’s native utility token (HBAR) at the lowest possible pricing.

The HBAR token has a dual role within the Hedera public network.

First and foremost, HBAR the fuel that powers Hedera services, such as smart contracts, file storage and regular transactions. Second, it's used to help secure the network, since HBAR users can stake their tokens to assist with maintaining the integrity of the platform.

Hedera (HBAR) is the native cryptocurrency of Hedera Hashgraph, a platform that is positioned as an alternative to traditional blockchain technology and aims to excel in speed, efficiency and security.

Older blockchains tend to use a consensus mechanism like proof-of-work (PoW) to validate transactions, while younger blockchains opted for proof-of-stake (PoS). The Hedera Hashgraph system has a structure that was created from scratch particularly for the project. Hedera is based on a PoS model that is believed to increase the efficiency of transaction verification in the network, provide a high level of security, and protect the network from hacker attacks. Its ecosystem has the underlying hashgraph consensus algorithm and the global enterprise governing body.

Hedera Hashgraph is a distributed ledger technology (DLT). According to the project website, Hedera differs from other blockchains because it uses a new consensus algorithm called hashgraph. It intends to process and execute transactions faster, eliminate delays, and smooth out the TPS (transactions per second) indicator. Hashgraph is claimed to be an upgrade in transaction speed, cost, and scalability.

Core network services by Hedera:

Consensus Service (HCS). With HCS, clients send messages to the network to negotiate consensus timestamping and order. In this case, the state is stored offline, and users can define privacy and access control.

Hedera Token Service (HTS). Thanks to HTS, token creation and management are available to customers. It supports built-in tokenization.

The goal of Hedera’s hashgraph is to increase the speed of transactions. Moreover, the network is also focused on high-volume operations: micropayments, data integrity and tokenization.

Like the EVM, the Hedera network maintains a virtual machine that writes smart contracts in the Solidity programming language. On top of that, Hedera offers a set of built-in KYC and AML checks.

From a technical point of view, Hedera is a form of distributed ledger technology. It is a hashgraph, or consensus algorithm, where users agree on the order in which transactions should be performed. However, Hedera is not exactly a blockchain. It has its own distinctiveness and works differently. With hashgraph, all transaction branches are merged, no block equivalent is thrown away, and each is used to reach consensus.

One of the most noticeable features of the network is the Gossip-about-Gossip protocol. According to Dr. Leemon Baird, Hedera's inventor, within the system nodes randomly transmit data about themselves to other nodes via hashgraph using the Gossip protocol. Soon, all nodes in a cluster become familiar with each other. Then a certain data structure is formed. It consists of a payload of transactions, a timestamp, a digital signature, and hashes to the previous structures.

HBAR is Hedera's native token that powers applications on the Hedera network. HBAR is utilized to pay for network services, transaction fees, in-app payments and micropayments. Developers can pay network fees with HBAR tokens, namely: work with smart contracts, file storage and currency exchange. HBAR is used to incentivize and pay network nodes.

Hedera Hashgraph has a decentralized governance system that is set apart. All critical decisions about pricing policy, software updates, and wealth management are made by the Governing Council.

The XDC Network is a blockchain developed to support trade finance and the tokenization of RWAs. A highly optimized, EVM-compatible Layer 1 blockchain, XDC Network reaches consensus through a delegated proof-of-stake (dPoS) mechanism, which allows for a transaction time of mere seconds, near zero gas fees, and a high number of transactions per second (TPS).

Secure, scalable, and highly efficient, the XDC Network powers a wide range of novel blockchain use cases and provides state-of-the-art infrastructure for enterprise-grade blockchain applications. With architecture that enables the creation of sovereign sub-networks, XDC Network is uniquely equipped to support those who require dedicated blockchain environments for enhanced permissions and control, such as government agencies, financial institutions, and businesses.

As of April 25, 2024, there are 312 XDC Network validator masternode candidates, of which 108 actively operate as validator masternodes, and the remainder are standby masternodes. Each masternode operator is required to stake 10M XDC.

A forthcoming upgrade to the consensus mechanism, dubbed XDC 2.0, is currently running on testnet. It and subsequent iterations of the XDC Network protocol will further enhance the security of the consensus mechanism and incorporate a novel "judiciary branch" into the consensus mechanism.

Developed by Princeton University's Pramod Viswanath, Hash Laboratories' Fisher Yu, and their team, XDC 2.0’s cutting-edge compliance technology will ensure unprecedented Byzantine fault tolerance (BFT) by holding validators accountable for their actions on an automated yet discretionary basis.
