Kaspa

## **What Is KASPA (KAS)?**

Kaspa is a [proof-of-work](https://coinmarketcap.com/alexandria/glossary/proof-of-work-pow) (PoW) cryptocurrency which implements the GHOSTDAG protocol. Unlike traditional [blockchains](https://coinmarketcap.com/alexandria/glossary/blockchain), GHOSTDAG does not orphan [blocks](https://coinmarketcap.com/alexandria/glossary/block) 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.


## Who Are the Founders of Kaspa?

Kaspa was envisioned by R&D company DAGLabs, through investment by PolyChain.

Nonetheless, Kaspa is a community project, completely open source, no central governance, and no business model.

The founder is Yonatan Sompolinsky, Postdoc CS at Harvard University on the MEV Research Team.

Yonatan's 2013 paper on Ghost protocol is cited in the Ethereum Whitepaper.

Kaspa core developers and contributors include Cryptography Doctoral student Shai Wyborski, CS Master Michael Sutton, Mike Zak CS Undergrad Studies, Cryptography researcher Elichai Turkel, and Developer Ori Newman - all of whom contributed immensely to the implementation and stabilization of the network.


## What Makes Kaspa Unique?

Kaspa is unique in its ability to support high block rates while maintaining the level of security offered by proof-of-work environments. Kaspa’s current main net operates at 1 block per second. Down the road, core developers and researchers will work on stretching the capability to the limits—think 10 or even 100 blocks per second.

Kaspa also includes a unique monetary policy which decreases emissions geometrically over time based on the 12-note scale of music. Known as the chromatic phase - this policy activated May 7th 2022 with a block reward of 440 KAS. The block reward will be halved once per year, but smoothly: every month, the block reward is reduced by a factor of (1/2)^(1/12). This means that the ratio of block rewards in consecutive months is exactly the same as the ratio of frequencies of two consecutive semitones in a tempered chromatic scale. The initial block reward is the frequency of the note A4, and every averaged year is hence called an octave.

Note that the policy dictates how many coins are minted per second regardless of the block rate. Should Kaspa change the block rate in the future, the reward will be adjusted accordingly to maintain the same emission rate.

In addition, all forms of financial markets such as spot, perpetual, futures and options are fully on-chain. The decentralized cross-chain bridging infrastructure is compatible with Ethereum, IBC-enabled blockchains, and non EVM chains such as Solana.

Injective also provides a next-generation, highly interoperable smart contract platform based on CosmWasm, with advanced interchain capabilities. Injective is custom built with the Cosmos SDK and utilizes Tendermint-based Proof-of-Stake consensus mechanism, providing instant transaction finality with the ability to sustain lightning-fast performance (10,000+ TPS).

The Injective ecosystem includes 100+ projects and over 150,000 community members globally. Injective is backed by a group of prominent investors such as Binance, Pantera Capital, Jump Crypto and Mark Cuban.

Injective’s core exchange module provides state-of-the-art capabilities including an advanced on-chain order book and matching engine for spot, perpetual, futures and options markets, resistance to Miner-Extractable Value (MEV) through frequent batch auction order matching, and zero gas fees for users.

Injective natively uses IBC and is highly-interoperable with multiple layer 1s, including, but not limited to, Polygon and Solana (through an upcoming Wormhole integration). It is also uniquely built to be interoperable with Ethereum, through its own decentralized ERC-20 token bridge, making Injective the first network within the Cosmos ecosystem to natively support Ethereum assets.

Smart contracts are implemented on Injective through CosmWasm, allowing for multi-chain smart contract transactions to occur seamlessly. Injective, however, is the only blockchain that enables automatic smart contract execution. This capability serves as a powerful building block for developers to create novel use cases that would not be possible on any other chain.

The use cases intended for INJ include but are not limited to: protocol governance, dApp value capture, Proof-of-Stake (PoS) security, developer incentives and staking. Further details regarding each of these use cases can be found below:

Protocol Governance: The INJ token governs every single component of Injective, including chain upgrades. Since its mainnet launch, the Injective community has actively contributed to governance, with all proposals passing through a DAO governance vote. The comprehensive governance page is available here.

Protocol Fee Value Capture: 60% of all fees generated from dApps enter an on-chain buy-back-and-burn auction to maintain the deflationary nature of INJ. The burn auction page is available here.

Tendermint-based Proof-of-Stake (PoS) Security: INJ is used to secure the Injective blockchain using a proof-of-stake mechanism. Validators and delegators can both participate in staking.

Developer Incentives: 40% of fees generated by users on dApps built on Injective go directly towards incentivizing new developers building on Injective which brings an ever growing funnel of builders to Injective.

Arbitrum is an Ethereum layer-two (L2) scaling solution. It uses optimistic rollups to achieve its goal of improving speed, scalability and cost-efficiency on Ethereum. Arbitrum benefits from the security and compatibility of Ethereum. Another benefit is the higher throughput and lower fees compared to Ethereum. That is made possible thanks to moving most of the computation and storage load off-chain.

Arbitrum’s native token is called ARB and is used for governance. Offchain Labs, the developers behind Arbitrum, announced the shift to a decentralized autonomous organization (DAO) structure — the Arbitrum DAO. ARB holders can vote on proposals that affect the features, protocol upgrades, funds allocation and election of a Security Council.

Arbitrum has an ambitious roadmap for 2023, which includes: Launching its own layer-three solution called Orbit; Enabling developers to deploy programs written in popular programming languages like Rust, C++, and more using Stylus; Expanding its validator set to include more independent institutional validators; Moving its protocol to layer two with Arbitrum One.

On March 16, 2023,  Arbitrum announced their highly anticipated airdrop of ARB. The token will be airdropped to early users and DAOs building on Arbitrum, with 12.75% of the total supply to be distributed. Recipients were rewarded on a point-based system depending on their interaction with the Arbitrum network until a cutoff date of March 1, 2023. The token generation event is on March 23, 2023.

SingularityNET is a blockchain-powered platform that allows anybody to easily "create, share, and monetize" AI services, thanks to its globally-accessible AI marketplace.

Through the SingularityNET marketplace, users can browse, test and purchase a huge variety of AI services using the platform’s native utility token — AGIX. Moreover, the marketplace represents an outlet AI developers can use to publish and sell their AI tools, and easily track their performance.

With the benefits of LLMs and generative AI are increasingly exciting, their limitations are also becoming increasingly apparent. The convergence of structured knowledge with neural networks is emerging as the key to overcoming their shortcomings.

Uniquely positioned at the heart of this convergence, SingularityNET will prioritize the integration of Knowledge Graphs (KGs) and comprehensive Neural Symbolic tools for LLMs, with the goal of empowering developers to create the next generation of AI systems on the SingularityNET Platform.

SingularityNET is strategically positioned to become the Knowledge Layer of the Internet, leading the evolution of the emerging AI landscape while also laying the foundations for the Artificial General Intelligence (AGI) of tomorrow.

The team behind SingularityNET pioneered the development of an AI known as Sophia, which is described as the "world's most expressive robot". SingularityNET’s goal is to enable Sophia to be able to fully understand human language, and continue developing “OpenCog” — an AI framework that is hoped to eventually achieve a state known as “advanced general intelligence,” i.e. human-level artificial intelligence (or beyond).

The platform was first announced in 2017 and completed an initial coin offering (ICO) in December the same year, raising $36 million in just one minute.

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.

Solana is a highly functional open source project that banks on blockchain technology’s permissionless nature to provide decentralized finance (DeFi) solutions. While the idea and initial work on the project began in 2017, Solana was officially launched in March 2020 by the Solana Foundation with headquarters in Geneva, Switzerland.

To learn more about this project, check out our deep dive of Solana.

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.

Polygon (previously Matic Network) is the first well-structured, easy-to-use platform for Ethereum scaling and infrastructure development. Its core component is Polygon SDK, a modular, flexible framework that supports building multiple types of applications.

To learn more about this project, check out our deep dive of Polygon Matic.

Using Polygon, one can create optimistic rollup chains, ZK rollup chains, stand alone chains or any other kind of infra required by the developer.

Polygon effectively transforms Ethereum into a full-fledged multi-chain system (aka Internet of Blockchains). This multi-chain system is akin to other ones such as Polkadot, Cosmos, Avalanche etc. with the advantages of Ethereum’s security, vibrant ecosystem and openness.

The $MATIC token will continue to exist and will play an increasingly important role, securing the system and enabling governance.

Polygon (formerly Matic Network) is a Layer 2 scaling solution backed by Binance and Coinbase. The project seeks to stimulate mass adoption of cryptocurrencies by resolving the problems of scalability on many blockchains.

Polygon combines the Plasma Framework and the proof-of-stake blockchain architecture. The Plasma framework used by Polygon as proposed by the co-founder of Ethereum, Vitalik Buterin, allows for the easy execution of scalable and autonomous smart contracts.

Nothing will change for the existing ecosystem built on the Plasma-POS chain. With Polygon, new features are being built around the existing proven technology to expand the ability to cater to diverse needs from the developer ecosystem. Polygon will continue to develop the core technology so that it can scale to a larger ecosystem.

Polygon boasts of up to 65,000 transactions per second on a single side chain, along with a respectable block confirmation time of less than two seconds. The framework also allows for the creation of globally available decentralized financial applications on a single foundational blockchain.

The Plasma framework gives Polygon the potential of housing an unlimited number of decentralized applications on their infrastructure without experiencing the normal drawbacks common on proof-of-work blockchains. So far, Polygon has attracted more than 50 DApps to its PoS-secured Ethereum sidechain.

MATIC, the native tokens of Polygon, is an ERC-20 token running on the Ethereum blockchain. The tokens are used for payment services on Polygon and as a settlement currency between users who operate within the Polygon ecosystem. The transaction fees on Polygon sidechains are also paid in MATIC tokens.

Polygon

The $BEAM token serves as the native crypto asset for the Beam network, a gaming network empowered by the Merit Circle DAO. Beam is an ecosystem where gamers and developers come together to shape the future of the gaming industry. One of its core components is the Beam SDK, which is a flexible software development kit that enables game developers to choose between a variety of tools that can be used to fuel and structure their in-game blockchain elements.

To interact with Beam, $BEAM is required. This is the native crypto asset used within the Beam network to pay for transactions. This not only includes transfers of assets but also involves all interactions with smart contracts on the Beam network, facilitating a seamless, immersive gaming experience.

Besides functioning as a gas token that fuels the Beam network, $BEAM is the heart of the governance of the Merit Circle DAO. This decentralized autonomous organization (DAO) was brought to live in early 2021 to revolutionize the gaming industry. The $BEAM token allows its holders to participate in governance of this DAO.

Beam

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.

Avalanche

NEAR Protocol is a layer-one blockchain that was designed as a community-run cloud computing platform and that eliminates some of the limitations that have been bogging competing blockchains, such as low transaction speeds, low throughput and poor interoperability. This provides the ideal environment for DApps and creates a developer and user-friendly platform. For instance, NEAR uses human-readable account names, unlike the cryptographic wallet addresses common to Ethereum. NEAR also introduces unique solutions to scaling problems and has its own consensus mechanism called “Doomslug.”

NEAR Protocol is being built by the NEAR Collective, its community that is updating the initial code and releasing updates to the ecosystem. Its declared goal is to build a platform that is “secure enough to manage high value assets like money or identity and performant enough to make them useful for everyday people.”

Flux, a protocol that allows developers to create markets based on assets, commodities, real-world events, and Mintbase, an NFT minting platform are examples of projects being built on NEAR Protocol.

NEAR Protocol

Quant launched in June 2018 with the goal of connecting blockchains and networks on a global scale, without reducing the efficiency and interoperability of the network. It is the first project to solve the interoperability problem through the creation of the first blockchain operating system.

To learn more about this project, check out our deep dive of Quant.

The project is built as an operating system distributed ledger technology— and Overledger Network — for connecting different blockchain networks. The project is billed as the first OS to be built for blockchains.

The main aim of Quant — using Overledger — is to bridge the gap that exists between different blockchains. The backbone of the project is the Overledger network, which Quant bills as the ecosystem on which the future digital economy ecosystem will be built.

Overledger allows developers to build decentralized multi-chain applications (known as MApps) for their customers. For developers to build a Mapp on the network, they must hold a certain amount of Quant tokens (QNT).
