## Τι είναι το ICON (ICX);

Το ICON είναι ένα οικοσύστημα blockchain που σχεδιάστηκε για να διευκολύνει την αλληλεπίδραση πολλαπλών blockchain μέσω του μοναδικού στρώματος διαλειτουργικότητας του. Εγκαινιασμένο το 2017 από μια ομάδα της Νότιας Κορέας, το ICON στοχεύει στο να επιτρέψει σε διαφορετικά blockchain να επικοινωνούν μεταξύ τους, επιτρέποντας την άνετη ανταλλαγή ψηφιακών νομισμάτων και έξυπνων συμβολαίων. Αυτό επιτυγχάνεται μέσω του Cross-Chain Framework του ICON, το οποίο απλοποιεί τη διαδικασία ανάπτυξης διασυνδεδεμένων αλυσίδων, καθιστώντας ευκολότερη τη λειτουργία εφαρμογών σε διάφορα blockchain.

Το δίκτυο λειτουργεί με έναν μηχανισμό συναίνεσης delegated proof-of-stake (DPoS). Σε αυτό το σύστημα, οι κάτοχοι ICX στοιχηματίζουν τα νομίσματά τους και τα αναθέτουν σε Δημόσιους Εκπροσώπους (P-Reps), οι οποίοι είναι υπεύθυνοι για την παραγωγή μπλοκ και τη συμμετοχή στη διακυβέρνηση του δικτύου ICON. Αυτή η προσέγγιση επιτρέπει στους κατόχους ICX να κερδίζουν αμοιβές παθητικά ενώ επιτρέπει σε εκείνους που ενδιαφέρονται για τις τεχνικές και διακυβερνητικές πτυχές του δικτύου να συμμετέχουν ενεργά.

Το ICON συν-ιδρύθηκε από τον Min Kim, ο οποίος έχει παρελθόν τόσο στον χρηματοοικονομικό όσο και στον τομέα διανομής ψηφιακού περιεχομένου. Η συμμετοχή του στο

### Πώς εξασφαλίζεται το ICON (ICX);

Το Δίκτυο ICON χρησιμοποιεί έναν μηχανισμό συναίνεσης αποδεικτικής εντολής (DPoS) για να διασφαλίσει την ασφάλεια και την ακεραιότητά του. Αυτό το σύστημα επιτρέπει στους κατόχους ICX να αναθέτουν τα διακριτικά τους σε Δημόσιους Εκπροσώπους (P-Reps), οι οποίοι είναι υπεύθυνοι για την παραγωγή μπλοκ και τη συμμετοχή στη διακυβέρνηση του δικτύου. Αυτό το μοντέλο ενθαρρύνει την ενεργή συμμετοχή από την κοινότητα ενώ επιτρέπει στους ενδιαφερόμενους να κερδίζουν ανταμοιβές μέσω του staking.

Για να γίνει κάποιος P-Rep και να συμμετάσχει στη διακυβέρνηση του δικτύου, τα άτομα ή οι ομάδες πρέπει να υποβληθούν σε μια διαδικασία εγγραφής, η οποία περιλαμβάνει ένα τέλος. Αυτή η διαδικασία διασφαλίζει ότι μόνο δεσμευμένοι και ικανοί επικυρωτές συμβάλλουν στις λειτουργίες του δικτύου. Η ανατεθειμένη φύση του μηχανισμού συναίνεσης του ICON σημαίνει ότι ακόμη και εκείνοι που δεν έχουν την τεχνική γνώση για να διαχειριστούν έναν κόμβο μπορούν ακόμα να συμμετάσχουν στην ασφάλεια του δικτύου μέσω του staking των ICX τους και αναθέτοντάς τα σε έναν P-Rep της επιλογής τους.

Επιπλέον, το ICON περιλαμβάνει τακτικούς ελέγχους ασφαλείας και μια αφιερωμένη ομάδα ειδικών ασφαλείας για να παρακολουθούν και να

### Πώς θα χρησιμοποιηθεί το ICON (ICX);

Το ICON είναι σχεδιασμένο ως ένα πολυσύνθετο πρωτόκολλο blockchain που στοχεύει στη διευκόλυνση των αποκεντρωμένων εφαρμογών (DApps) και επιτρέπει στα ανεξάρτητα blockchain να αλληλεπιδρούν μεταξύ τους μέσω της μοναδικής διασυνδεσιμότητας του ICON. Αυτή η διασυνδεσιμότητα επιτυγχάνεται μέσω του Πλαισίου Διασυνδεδεμένων Αλυσίδων του ICON, το οποίο επιτρέπει στα διάφορα blockchain να επικοινωνούν και να μοιράζονται πληροφορίες ομαλά. Το πλαίσιο είναι σχεδιασμένο να είναι προσβάσιμο, επιτρέποντας στους προγραμματιστές να δημιουργούν και να ενσωματώνουν εφαρμογές σε διάφορα blockchain χωρίς την ανάγκη να κατανοούν τις υποκείμενες πολυπλοκότητες κάθε αλυσίδας.

Το Δίκτυο ICON τροφοδοτείται από το νομισματικό του σύμβολο, το ICX, το οποίο διαδραματίζει κεντρικό ρόλο στη συντήρηση και λειτουργία του οικοσυστήματος ICON. Το ICX χρησιμοποιείται για αρκετές βασικές λειτουργίες εντός του δικτύου:

1. **Διακυβέρνηση**: Οι κάτοχοι ICX μπορούν να συμμετέχουν στη διακυβέρνηση του Δικτύου ICON στοιχίζοντας τα νομίσματά τους και αναθέτοντάς τα σε Δημόσιους Αντιπροσώπους (P-Reps). Αυτοί οι P-Reps είναι υπεύθυνοι για την επικύρωση συναλλαγών, την παραγωγή μπλοκ και τη συμμετοχή στη διαδικασία λήψης αποφάσεων σχετικά με τη με

### Ποια είναι τα κύρια γεγονότα που έχουν συμβεί για το ICON (ICX);

Το ICON έχει βιώσει αρκετές καθοριστικές στιγμές που έχουν συμβάλει σημαντικά στην ανάπτυξη και την ανάπτυξή του εντός του οικοσυστήματος blockchain. Ειδικότερα, η κυκλοφορία του Central Relay και του GMP 2.1 τον Μάρτιο του 2024 σηματοδότησε μια σημαντική τεχνολογική πρόοδο για το δίκτυο. Αυτή η ενημέρωση ήταν κρίσιμη για την ενίσχυση των δυνατοτήτων και της αποδοτικότητας του δικτύου.

Ένα άλλο κρίσιμο γεγονός ήταν η εκκίνηση του Πλαισίου Διαλειτουργικότητας του ICON. Αυτή η ανάπτυξη ήταν καθοριστική για τη διευκόλυνση των απρόσκοπτων διασυνδέσεων μεταξύ αλυσίδων, επιτρέποντας ένα πιο διασυνδεδεμένο οικοσύστημα blockchain. Επιτρέποντας σε διαφορετικά blockchain να επικοινωνούν και να μοιράζονται πληροφορίες, το ICON έχει θέσει τον εαυτό του ως ηγέτη στην προώθηση της διαλειτουργικότητας blockchain.

Επιπλέον, η καύση των τελών ICX που παράγονται από εφαρμογές που χρησιμοποιούν την τεχνολογία ICON αντιπροσωπεύει ένα σημαντικό ορόσημο. Αυτός ο μηχανισμός δεν βοηθά μόνο στη μείωση της συνολικής προσφοράς του ICX, ενδεχομένως επηρεάζοντας την αξία του, αλλά επίσης δείχνει τη δέσμευση του ICON στη δημιουργία ενός βιώσιμου και οικονομικά βιώσιμου οικοσυστήματος.

### Ποιοι είναι οι ιδρυτές του ICON (ICX);

Το Δίκτυο ICON συν-ιδρύθηκε από τον Min Kim και τον JH Kim, οι οποίοι και οι δύο φέρνουν μια πλούσια εμπειρία από τους τομείς των fintech και της διανομής ψηφιακού περιεχομένου. Ο Min Kim, με παρελθόν ως πρώην επικεφαλής στρατηγικής αξιωματούχος ενός μεγάλου fintech holding εταιρείας στην Κορέα και ως επικεφαλής λειτουργικός αξιωματούχος σε μια πλατφόρμα διανομής ψηφιακού περιεχομένου στις Η.Π.Α., έχει μια στέρεη βάση στην επιχειρηματική στρατηγική και ανάπτυξη. Η εκπαίδευσή του από το Haas School of Business στο University of California, Berkeley, συμπληρώνει περαιτέρω τον ρόλο του στην κατεύθυνση του έργου ICON προς τους στόχους του. Ο Min Kim έπαιξε επίσης έναν καθοριστικό ρόλο στην εκκόλαψη της ICONLOOP, η οποία λειτουργεί ως τεχνικός εταίρος του ICON, υπογραμμίζοντας τον καθοριστικό του ρόλο στην τεχνική και στρατηγική ανάπτυξη του Δικτύου ICON.

Οι συνεισφορές του JH Kim στο ICON, αν και δεν περιγράφονται λεπτομερώς στις παρεχόμενες πληροφορίες, μπορεί να θεωρηθεί ότι είναι εξίσου σημαντικές, δεδομένης της συνεργατικής φύσης τέτοιων καινοτόμων έργων. Μαζί, οι συνδυασμένες προσπάθειές τους έχουν τοποθετήσει το ICON ως έναν αξιοσημείωτο παίκτη στον χώρο του blockchain, επικεντρωμένο στη διαλειτουργικότητα και την άνευ ραφής διασυνδεσιμότητα μετα

## What Is ICON Network (ICX)?

Apps use [ICON](https://coinmarketcap.com/currencies/icon/) to operate cross-chain seamlessly, build momentum and gain reputation. ICON's Cross-Chain Framework simplifies cross-chain development with its easy-to-use xCall messaging standard and connections to secure bridging protocols.

## Who Are the Founders of ICON Network?

ICON Network was co-founded by Min Kim, the former chief strategy officer of DAYLI Financial Group, Korea’s largest fintech holding company, and the chief operating officer at Tapas Media, a U.S. digital content distribution platform. He is also an alumnus of Haas School of Business at the University of California in Berkeley. Min Kim incubated ICONLOOP, ICON’s technical partner.  


## What Makes ICON Network Unique?

ICON's native ICX coin fuels interoperability with a sizeable percentage of all these fees collected in ICX are burned. Apps, written in any programming language, can use the ICON Cross-Chain Framework on a growing list of blockchains. Visit the ICON Community website (https://icon.community/ )  for an up to date overview of connected blockchains!


## How Is the ICON Network Secured?

ICON is a delegated proof-of-stake (DPoS) network, which means a majority of stakeholders delegate their share of the network – in this case, ICX – to registered validators that produce blocks and participate in governance. ICON’s DPoS consensus lets non-technical stakeholders benefit from staking without having to set up a node or join a staking pool.

On ICON, ICX holders can stake and delegate ICX to P-Reps – entities that have registered to participate in governing the ICON blockchain. This DPoS implementation offers the best of both worlds – stakers can passively earn rewards, while technical individuals that are actually interested in setting up infrastructure and governing ICON can do so.

The ICON blockchain is governed by Public Representatives (P-Reps). To become a P-Rep, a team or individual must go through an on-chain registration process which includes paying a 2,000 ICX registration fee. Following registration, a P-Rep can start receiving delegation in the form of staked ICX.

🌐 ICON Network is a layer-one blockchain focused on building a multichain bridging solution that is scalable, chain-agnostic, and secure!

Ontology is a project designed to bring trust, privacy, and security to Web3 through decentralized identity and data solutions. It is building the infrastructure to provide trusted access to Web3, allowing individuals and enterprises to rest assured that through regulatory compliant digital identity solutions, users and their privacy come first.

The Ontology blockchain is a high speed, low cost public blockchain. It is designed to bring decentralized identity and data solutions to Web3, with the goal of increasing privacy, transparency, and trust. To achieve this, users and enterprises are provided with the flexibility to build blockchain-based solutions that suit their needs, while also ensuring regulatory compliance. Through Ontology’s Ethereum Virtual Machine (EVM), Ontology ensures frictionless compatibility with Ethereum, the first step in the creation of the Ontology Multi-Virtual Machine and further interoperability for the chain.

At its launch, Ontology chose to forego the popular initial coin offering (ICO) model in favor of a series of community distributions and airdrops of its ONT cryptocurrency.

This helped to quickly establish both organic price discovery and a passionate community and helped the project to avoid subsequent regulatory scrutiny.

For example, for a brief period any person who signed up for the Ontology newsletter received an airdrop of free 1,000 ONT, which reached a value of $10 per token soon after the token became listed on major exchanges like Binance.

Ontology launched its own MainNet on June 30, 2018 and has been up and running smoothly since.

Qtum (pronounced ‘“quantum”)  is a proof-of-stake (PoS) smart contract open-source blockchain platform and value transfer protocol. It aims to bring together the strengths of Bitcoinand Ethereumin one chain. Qtum is built on Bitcoin's UTXO transaction model, with the added functionality of smart contract execution and DApps. Recently, the platform added support for DeFi applications. As of March 2021, there are more than 20 tokens created on the Qtum blockchain.

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

The project was announced in March 2016 and held an ICO a year after, in March 2017, which brought its founders $15 million USD. The Qtum main chain was released on Sept.13, 2017. Initially, the Qtum coin was issued as a ETH-20 token, but with the launch of the mainnet, it was converted to native blockchain.

Qtum

NEM is a blockchain platform that was launched in March of 2015. It was one of the pioneers of the cryptocurrency industry, and sought to improve on the imperfections found on other chains at the time. It was one of the first non-turing complete chains to feature user-defined tokens (called mosaics), namespaces, multisignature accounts, and a P2P reputation system based on EigenTrust++. Its most notable contribution to the space is the proof-of-importance consensus mechanism, which sought to reward on-chain activity and deter the concentration of wealth commonly associated with proof-of-stake. Its client, NIS, is written in Java.

NEM has a global community. It sees the most utility as an alternative form of payment for businesses and vendors, and has a variety of social media apps built on top of it in Japan, such as nemgraph, a community-driven owned and operated alternative to Instagram.

In December 2021, NEM was hard forked by a pseudonymous team of cryptocurrency experts and enthusiasts alike. Titled Harlock, this hard fork signaled the community’s intent to take NEM from a shadow of its former self into the world’s leading payments platform for on-chain and off-chain media content.

Zilliqa is a public, permissionless blockchain that is designed to offer high throughput with the ability to complete thousands of transactions per second. It seeks to solve the issue of blockchain scalability and speed by employing sharding as a second-layer scaling solution. The platform is home to many decentralized applications, and as of October 2020, it also allows for staking and yield farming.

Development work officially started on Zilliqa in June 2017, and its testnet went live in March 2018. A little over a year later, in June 2019, the platform launched its mainnet.

The native utility token of Zilliqa, ZIL, is used to process transactions on the network and execute smart contracts.

Zilliqa

OMG Network, formerly known as OmiseGo, is a non-custodial, layer-2 scaling solution built for the Ethereum blockchain. As an Ethereum scaling solution, OMG Network is designed to allow users to transfer ETH and ERC20 tokens significantly faster and cheaper than when transacting directly on the Ethereum network.

The network is based on a novel scaling solution called MoreViable Plasma, which uses a sidechain architecture to group several transactions off-chain into a batch, which can then be verified as a single transaction on the Ethereum root chain. According to OMG Network, this technology has the potential to scale Ethereum to thousands of transactions per second (TPS) — instead of the 10 to 14 tps Ethereum 1.0 is currently capable of.

The network is powered by the OMG utility token, which can be used as one of the payment methods for fees on the OMG Network, and will eventually be stakable — helping to secure the network in return for rewards.

Billed as "digital money for the modern world," nano is a lightweight cryptocurrency that is designed to facilitate secure, practically instant payments, without fees, and addresses some of the major limitations of both legacy financial infrastructure, and many modern cryptocurrencies.

Development of the project began in 2014 under the name RaiBlocks, and the coin (then termed XRB) launched the following year through a public faucet, which allowed users to claim small amounts of XRB after completing a captcha challenge. Anyone with access to a computer or phone could solve captchas, and be rewarded with RaiBlocks. The number of XRB people received per solved captcha varied over time

RaiBlocks (XRB) was rebranded to Nano in January 2018, with the new name chosen to better represent the speed and simplicity the project offers to users.

It is a peer-to-peer platform that uses a unique block-lattice data structure to allow users to easily transfer value to one another without relying on centralized intermediaries.

Unlike other platforms which typically use the combined proof-of-work of a massive mining network to achieve consensus, nano instead uses a system known as Open Representative Voting (ORV) — which sees account holders vote for their chosen representative, who then work to confirm blocks of transactions securely.

ORV makes Nano extremely energy efficient, positioning it as a more environmentally friendly alternative to proof-of-work (POW)-based cryptocurrencies.

In November, 2021, aiming to bring nano to the real world and to comply with the globally-recognized standards of the International Organisation for Standardisation (ISO) requirements, nano adopted a new ticker and a standard symbol: XNO and Ӿ.

Nano

Tezos is a high-performing blockchain and open-source platform for assets and applications, with a strong focus on code security, on-chain governance, and decentralization. Tezos 2.0, the upcoming step in the evolution of Tezos, aims to improve scalability (via layer 2s), composability, and to implement support to mainstream programming languages (like Javascript, Typescript, Python, and many others).

Initially built with formal verification in mind, the Tezos protocol enables builders to avoid bugs when developing smart contracts, making it particularly suited to applications that require a high degree of security and certainty.

Tezos’ LPoS (Liquid Proof-of-Stake) consensus mechanism enables any stakeholder to take part, directly or by delegation, in the consensus process, and to be rewarded for securing the network. Rather uniquely, Tezos’ on-chain governance system also enables stakeholders to create and vote on protocol upgrade proposals. This pioneering system allows the protocol to self-amend and upgrade itself without leading to a split (or fork) in the blockchain, empowering the community without slowing down innovation.

First proposed in 2014 and launched in 2018, the Tezos Mainnet has a proven track record of running uninterrupted ever since, having earned a strong reputation for technical excellence and a supportive community.

Tezos

Basic Attention Token, or BAT, is the token that powers a new blockchain-based digital advertising platform designed to fairly reward users for their attention, while providing advertisers with a better return on their ad spend.

To learn more about this project, check out our deep dive of Basic Attention Token.

This experience is delivered through the Brave Browser, where users can watch privacy-preserving adverts and receive BAT rewards for doing so. On the other hand, advertisers can deliver targeted ads to maximize engagement and cut down losses due to ad fraud and abuse.

The Basic Attention Token itself is the unit of reward in this advertising ecosystem, and is exchanged between advertisers, publishers and users. Advertisers pay for their advertising campaigns in BAT tokens. Out of this budget, a small portion is distributed to advertisers, while 70% is distributed to users — whereas the intermediaries that typically drive up advertising costs are cut out of the equation to improve cost-efficiency.

Basic Attention Token launched in 2017 following one of the fastest sell-out initial coin offerings (ICOs) of all time, with the platform raising a total of $35 million in under a minute. Since then, it has rolled out its attention-based advertising experience to users in most countries through its Brave Rewards program.

As of November 2020, the United States, the United Kingdom and Canada had the most active advertising campaigns.

Basic Attention Token

Band Protocol is a cross-chain data oracle platform that is able to take real-world data and supply it to on-chain applications, while also connecting APIs to smart-contracts to facilitate the exchange of information between on-chain and off-chain data sources.

By supplying reputable, verifiable real-world data to blockchains, Band Protocol unlocks a range of new use cases for developers to explore — since they can now use any type of real-world data as part of their decentralized application (DApp) logic, including sports, weather, random numbers, price feed data and more.

Band Protocol initially launched as an ERC-20 project on the Ethereum blockchain in September 2019, but transitioned to the Cosmos network in June 2020 with the release of Band Protocol 2.0. The new protocol is built on BandChain using the Cosmos SDK. Oracle nodes on BandChain not only relay data but are also involved in block production/validation, giving them a dual role.

BAND is the native token of the Band Protocol ecosystem and is used as collateral by validators involved in fulfilling data requests, as well as the main medium of exchange on BandChain — being used to paying for private data.

Band Protocol

The EOS Network is an open-source blockchain platform that prioritizes high performance, flexibility, security, and developer experience. As a third-generation blockchain platform powered by the EOS virtual machine, EOS has an extensible WebAssembly engine for deterministic execution of near fee-less transactions.

EOS is the market's most scalable, divisible, and programmable digital currency. EOS is a Delegated Proof of Stake (DPoS) network where stakeholders have the authority to select node operators. Due to the decentralized nature of the token distribution on EOS, power doesn't reside in the hands of block miners, but rather all parties involved in the EOS Network.

The EOS Network is attractive because of its technology and community. It allows developers to build projects that other blockchains cannot support. The network is straightforward and has multiple tools and educational resources to help users acclimate to the blockchain.

IOST describes itself as an “ultra-fast,” fully fledged and decentralized blockchain network and ecosystem with its own nodes, wallets and based on the “next-generation” consensus protocol dubbed “proof-of-believability.”

Ren (REN) is an open protocol built to provide interoperability and liquidity between different blockchain platforms.

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

Formerly known as Republic Protocol, Ren launched RenVM, its virtual machine mainnet, in May 2020, having completed a $34 million initial coin offering (ICO) in 2018.

The protocol’s native token, REN, functions as a bond for those running nodes which power RenVM, known as Darknodes.

Ren aims to expand the interoperability, and hence accessibility, of decentralized finance (DeFi) by removing hurdles involved in liquidity between blockchains.

Waves is a multi-purpose blockchain platform which supports various use cases including decentralized applications (DApps) and smart contracts.

Launched in June 2016 following one of the cryptocurrency industry’s earliest initial coin offerings (ICO), Waves initially set out to improve on the first blockchain platforms by increasing speed, utility and user-friendliness.

The platform has undergone various changes and added new spin-off features to build on its original design.

Waves’ native token is WAVES, an uncapped supply token used for standard payments such as block rewards.

DigiByte (DGB) is an open source blockchain and asset creation platform. Development began in October 2013 and the genesis block of its DGB token was mined in January 2014 as a fork of Bitcoin (BTC).

A longstanding public blockchain and cryptocurrency, DigiByte uses five different algorithms to improve security, and originally aimed to improve on the Bitcoin blockchain’s security, capacity and transaction speed.

DigiByte consists of three layers: a smart contract “App Store,” a public ledger and the core protocol featuring nodes communicating to relay transactions.

DigiByte

Siacoin (SC) is the native utility token of Sia, a blockchain-based distributed, decentralized cloud storage platform. Sia acts as a secure, trustless marketplace for cloud storage in which users can lease access to their unused storage space. Agreements and transactions are enforced with smart contracts, and Siacoin is the medium of exchange for paying for storage on the network. The main goal of the project is to become the "backbone storage layer of the internet."

Sia was originally announced in May 2014 before being revised and re-announced a year later in May 2015. It officially launched in June 2015.

Siacoin

Holo is a peer-to-peer distributed platform for hosting decentralized applications built using Holochain, a framework for developing DApps that does not require the use of blockchain technology. The goal of Holo is to serve as a bridge between the broader internet and apps built using Holochain, offering an ecosystem and marketplace in which DApps are easily accessible, as they are hosted on the internet by Holo network participants.

The Holo network will be facilitated using a token called HoloFuel, which is actively being tested and will act as an accounting system to pay hosts for their services. In 2018, the project minted an ERC-20 token, HOT — also known as HoloToken — as an "IOU" that will be redeemable for HoloFuel upon launch.

Holo is still in development and is expected to launch for open alpha and beta testing by 2021.

Holo

Harmony is a blockchain platform designed to facilitate the creation and use of decentralized applications (DApps). The network aims to innovate the way decentralized applications work by focusing on random state sharding, which allows creating blocks in seconds.

According to the project’s website, Harmony is expected to introduce cross-shard contracts and a cross-chain infrastructure by the end of 2021.
