Learning the friendly way

While you’ve likely come across the world of cryptocurrencies, you most probably have stumbled upon the term “blockchain”. But what is the blockchain solution? Blockchain is not only the revolutionary technology behind cryptocurrencies, it also has a large use case outside of the cryptocurrency and even the finance sector.

In the decade since blockchain technologies and digital ledger technology came to light, a host of blockchain networks have been created, most with their own digital currency. As the industry has grown and new blockchain networks have emerged, innovation in the space has increased significantly.

From the Ethereum blockchain providing a platform on which developers can create digital assets and smart contracts to corporate organizations implementing a private blockchain in order to streamline their services, the technology is propelling mankind forward in ways not witnessed in decades.

The blockchain solution provides much more than just digital assets, and industries far beyond just the payment processing ones are catching on. With traditional business networks incorporating the technology, the world of permissioned blockchain is igniting.

What is Blockchain?

Blockchain is a decentralized, transparent, immutable technology that keeps a public record of all information entered. Designed to record and distribute information, not to be edited. Also referred to as a public ledger, a blockchain keeps a record of all information ever inputted and stores it chronologically in blocks.

These blocks are linked to each other through a hashing system, which ensures that no one can ever tamper with the previous records, or try to manipulate the information on them. The “chain” of blocks make up the blockchain database.

The decentralized technology is not typically run by one entity, but rather from a variety of computers (also known as nodes) that make up the network, and work together to validate transactions and all information added to the blocks. Blockchain can be used in two forms, as a public blockchain or as private blockchain networks.

The public version allows anyone to view all information on the network, while the private reserves the information for members granted access.

The Advantages of Blockchain Technology

Powerful Technology

Invented in 2008 alongside Bitcoin by an anonymous entity Satoshi Nakamoto, blockchain is the technology that fueled the new way that money is transacted. Not only that, the technology offers incredible use cases far beyond the financial world. 

Fully Trusted, Fully Automated

One of the key features of blockchain is its ability to function without a central authority. The technology is designed to be maintained by various operating systems on the network, with full autonomy dispersed evenly. Information is stored on the blockchain in such a way that everyone can view it but no one can go back and tamper with it.

Powering Industries

While blockchain is the technology behind crypto, it also offers an incredible backbone to a diverse range of industries outside of this space. Companies like Nestle, Microsoft and Walmart are onboarding blockchain, proving to offer a strong and highly adaptable infrastructure to financial, property, and supply chain management entities. The number of blockchain companies is growing by the day.

The Core Benefits of a Blockchain Network

Decentralized

Blockchain networks are designed to be entirely decentralized meaning that there is no one central authority. The entire network is maintained by nodes (computers) around the world and no single entity has control. 

Immutable

Once the information has been added to a blockchain, no one can tamper, edit, or remove it. As information is verified and added to blocks, this solidifies its presence on the blockchain forever. 

Transparent

Blockchain offers a transparent view of all the activity that takes place on the network. This takes away the need for any checks or balances as all the information is available at any given time, in real-time.

What is the Difference Between a Public Blockchain and Private Blockchain?

When understanding what is blockchain, a common question is whether blockchain is secure. The answer is yes, blockchain is very secure.

Due to its decentralized nature, the technology requires a network of operators (computers) to verify and input all the information. As soon as one tries to input incorrect information or conduct illicit transactions, the network will recognize this and reject it immediately. 

The difference between a public and private blockchain is that public blockchain networks are open for anyone to see, while private blockchains are closed to an organization or a selected group of people.

Cryptocurrency networks are examples of public blockchain networks in that anyone can view all the transaction data. For a private blockchain, however, users will need special permission to access this information.

How is Blockchain Tamperproof?

Each block is made up of three things: the hash code of the previous block, the relevant information, and its own hash code.

When a new block is added, the new block will again have the hash of the previous block, the relevant information, and its own hash. This special sequence of hashes ensures that all blocks are stored chronologically, in a linear fashion, meaning that you cannot tamper with one block's information without tampering with every block after that.

Tampering with blocks would take an enormous amount of computing power and is largely considered impossible. Hence the security of using a digital asset or digital currency.

Blockchain Explained: How Does It Work

At its core, blockchain records and distributes information to a wide network of users that participate in verifying the information and maintaining the network. Let’s take a deeper look at Bitcoin transactions to further explain how blockchain works. 

If one user wanted to send a portion of Bitcoin to another user, they would require the user’s wallet address. Each wallet is made up of two codes, a public and private key, which enable the user to receive BTC (through the public key), as well as access BTC and conduct transactions (through the private key). The sender will then input the receiver’s wallet code and send the amount of Bitcoin they desire. 

This transaction will then enter a pool of transactions waiting to be verified by a miner on the network. The miner will ensure that the sender owns the amount they are sending, and verify the transaction along with a number of other transactions.

On the Bitcoin network, the size of one block is 1MB, which equates to roughly 3,200 transactions able to be stored in one block. When building a blockchain network, the size of the blocks can be increased or decreased to suit the use case. 

Once the transaction has been verified, the miner will record transactions processed and ensure they are added to the chain. The transaction ledger will then be distributed to the rest of the operators on the network. This new version will then override the older versions, and so on as more blocks are added.

Once the block is added to the blockchain and distributed, the funds will reflect in the receiver’s wallet. No need for a bank account or legal contracts, Bitcoin (and other digital currencies) operate entirely separately from traditional banking institutions and allow for the fast, efficient and cost-effective transaction of value.

Fraudulent transactions cannot take place as this will be flagged long before the block is added to the chain. Blockchain work in such a way that network participants can immediately flag ill actors and dismiss fraudulent financial transactions.

Understanding the Difference Between Blockchain and The Bitcoin Blockchain

The burning question: how does blockchain compare to Bitcoin. The answer is that it doesn’t, there are two separate, co-dependent technologies. Bitcoin, the cryptocurrency, is built on blockchain technology and requires it to function. There is no Bitcoin without blockchain technology.

Consider it the backbone of all cryptocurrencies. Blockchain technology, however, is an adaptable technology that can be used outside of the cryptocurrency industry. The technology can be used in any industry, provided that they require a transparent, immutable public ledger. 

One thing the two do have in common is that they were both introduced to the world at the same time. While the concept of blockchain technology was initially invented by researchers W. Scott Stornetta and Stuart Haber in 1991, it was referred to as distributed ledger technology (DLT) and was created purely to store office documents.

The anonymous entity Satoshi Nakamoto built on this and ultimately solved the double spending problem it was plagued with. In 2008, Nakamoto released both blockchain technology and Bitcoin in a whitepaper titled Bitcoin: A Peer-to-Peer Electronic Cash System.

The Bitcoin blockchain refers to the network, while blockchain technology refers to the technology as a whole.

In Conclusion

What is blockchain? Blockchain technology is the transparent, immutable storage of information. As mentioned earlier, this technology has use cases far outside of just the cryptocurrency and financial ecosystems.

Industries like renewable energy, supply chain management, and even farming sectors are now incorporating blockchain technology into their business systems, empowering them with a fully automated and safe means of storing records.

One of the largest and oldest dapps in the DeFi (decentralized finance) space, Compound Finance has built a reliable reputation among traders looking for lending and borrowing services. Compound operates using its native ERC-20 COMP tokens which provide community governance as well as other services.

What is the Compound protocol (COMP)?

Built on the Ethereum blockchain, the Compound protocol provides liquid money markets offering services such as lending and borrowing. Supporting a number of crypto assets, the Compound protocol allows users to deposit crypto into lending pools providing capital for borrowers on the network and allowing them to earn interest in return.

After depositing funds into the lending pool, lenders are issued "cTokens" (cETH, cDAI, cBAT) which represent the deposit made. These tokens can then be traded or transferred within the platform, or redeemed for the original cryptocurrency deposited. This process is conducted by smart contracts and operates entirely automatically with interest rates algorithmically assigned based on the activity in its liquidity pools. 

The Compound protocol also uses the ERC-20 native COMP token which is distributed to traders that utilize the Compound market, i.e. borrowing, withdrawing or repaying the asset. COMP tokens are distributed each time an Ethereum block is mined proportional to the interest collected from each asset. The COMP cryptocurrency grants COMP token holders governance and voting rights.

Following notable investments from the likes of consulting firm Bain Capital Ventures, Andreessen Horowitz, and Polychain, the platform has grown and established a strong reputation within the decentralized finance space and the greater crypto world.

The history of Compound and who created it

Compound was founded in 2017 by Robert Leshner and Geoffrey Hayes, who both previously held high-profile jobs at PostMates, an online food delivery service. Leshner holds the CEO position while Hayes remains the CTO at Compound Labs, Inc, the software development firm behind the Compound protocol. Compound Labs is an open-source software development firm creating cutting-edge tools, products, and services for the innovative DeFi ecosystem.

In 2018, the platform raised $8.2 million from notable venture capital firms Bain Capital Ventures and Andreessen Horowitz. A year later, Compound raised an additional $25 million from many of the same investors along with new ones including Paradigm Capital.

How does Compound work?

The Compound protocol leverages the power of Ethereum smart contracts and cryptocurrency incentives to benefit lenders and borrowers. Lend and borrow services make up the two main use cases for the platform, as outlined below.

Interest rates on Compound are dynamically managed based on the supply and demand of particular crypto assets within the coin pools. The higher the liquidity, the lower the interest rate. Prices are determined by using the Open Price Feed based on Chainlink's oracles which collect the data from numerous exchanges.

In order to use the Compound DeFi protocol to engage in lending or borrowing services, you will need to connect one of the supported crypto wallets. Currently, the app supports MetaMask, Ledger, WalletConnect, and Tally Ho. The interface has been designed to be user-friendly and easy to navigate, perfect for traders new to the space as well as seasoned DeFi participants.

Lending/supplying

The process of lending on the Compound platform is called supplying. Lenders are able to earn interest on their cryptocurrency by depositing cryptocurrencies into the Compound platform. Borrowers are also required to deposit digital assets into the protocol, which can earn interest but cannot be withdrawn for the duration of the borrowing period.

The platform currently supports roughly 20 crypto assets, from Basic Attention Token (BAT) to Wrapped Bitcoin (WBTC), with Ethereum (ETH) and a number of stablecoins (DAI, USDC, and USDT) being the most actively used.

Once users lend assets to the platform, they are issued with ERC-20-based cTokens corresponding to the cryptocurrency deposited (i.e. cETH, cDAI, etc.). These tokens confirm the liquidity providers' deposits and offer a number of other incentives.

Borrowing

After depositing a particular cryptocurrency into the decentralized finance protocol, users are assigned a "borrowing capacity". This is a limit set in USD based on the rate of the crypto asset which is determined by the Open Price Feed. When depositing multiple cryptocurrencies, the borrowing capacity will factor this in.

Users can also borrow cryptocurrencies supported by the protocol based on a coin's collateral ratio. For instance, if DAI has a collateral ratio of 70%, users can borrow DAI up to 70% of the total amount deposited. Typically, collateral ratios are between 60% and 85%.

Similar to the lending process, when borrowing cryptocurrency borrowers are issued cTokens. So when borrowing DAI for instance, borrowers will be issued cDAI tokens, with the interest payable based on these tokens as well.

Withdrawing

After paying back the borrowed debt, users can redeem their deposited funds. Without having to deal with other traders, the protocol seamlessly utilizes a dynamically maintained set of liquidity pools. The platform also does not charge any withdrawal penalties or hold users to minimum investment times.

When users redeem their funds, the cTokens issued are added to the accumulated interest and converted back to the originally deposited cryptocurrency. These funds can then be withdrawn into the connected wallet.

Account Health

The Compound platform uses a system called "account health" to establish whether accounts are in risk of liquidation. This system measures the sum of the deposited funds against the total amount borrowed. If a user's account health falls dangerously low, the account could be liquidated, and some of the collateral forfeited.

This process is managed in a decentralized way where platform users act as liquidators and monitor for risky accounts. Should they liquidate an account they earn a portion of the liquidated funds.

What is the COMP token?

The COMP token is the Compound platform's native token which mainly serves as a governance token, with a built-in incentive for users holding the token. Holders of COMP tokens are able to vote on all important decisions pertaining to the protocol, including interest rates. Much like the cTokens, COMP tokens are based on Ethereum’s ERC-20 token standard. 

Compound tokens have a total supply of 10,000,000 tokens, of which over 70% of Compound coins are in circulation (at the time of writing).

How can I buy COMP tokens?

With Tap's mobile app, users can easily acquire COMP tokens and store them in the integrated wallet with confidence, either to hold long-term, sell, trade or use on other DeFi platforms. Not only does Tap provide an effortless way of trading digital assets, but also a safe space to keep your investments secure over long periods of time.

In order to access the mobile app users will need to download the app and create an account. After a quick verification process, users have access to a wide range of vetted cryptocurrencies as well as fiat wallets where funds can be safely stored or used in the real world. Whether you're looking to buy Compound or sell Compound coins, Tap provides a seamless solution to your crypto needs.

USD Coin is a prominent stablecoin in the cryptocurrency market. Providing a plethora of use cases to both crypto and traditional investors, financial services and traders, USD Coin sits among the top 10 biggest cryptocurrencies by market capitalisation.

In this article, we explore this celebrated stablecoin and all it has to offer in terms of being a traditional investment opportunity, savings relief and digital value settlement service.

USD Coin is relatively new to the market, launching in September 2018. The stablecoin is pegged to the US dollar, meaning that its value will always reflect the price of the dollar on a 1:1 ratio.

This is established by keeping an equivalent amount of the circulating supply in a reserve account, i.e. for every 1 USDC in circulation, $1 needs to be held in reserve. The reserve is a mixture of cash and short-term U.S. Treasury bonds.

What Is The Point Of The USD Coin?

Built on top of the Ethereum network, USDC is a tokenised version of the US dollar that can operate over the internet and public blockchains. It is designed to provide a stable digital currency in an industry prone to volatility.

Setting itself apart in an increasingly saturated stablecoin market, USD Coin has received wide interest due to it providing a strong layer of transparency. The platform maintains strict protocols to ensure that the reserves are always at the correct levels, ensuring holders that they can withdraw 1 USDC for $1 at any given time, by way of enlisting a major accounting firm.

All USD holdings are required to be reported regularly by USDC issuers, which are in turn published by Grant Thornton LLP (as witnessed in the news). Unlike Bitcoin, while the company uses the decentralized network of Ethereum to function, it has a centralized agency controlling it.

Who Created USD Coin?

The coin was created by the Centre Consortium, a foundation consisting of the peer-to-peer payment service company, Circle and cryptocurrency exchange, Coinbase. Circle and Coinbase were the first commercial industry users of the stablecoin.

In 2020, Circle and Coinbase announced an upgrade to the USDC protocol and smart contracts. These upgrades were implemented to increase the cryptocurrency's usability for everyday payments, commerce and peer-to-peer transactions.

Both companies are well-funded and have achieved regulatory compliance, confirming the cryptocurrency's stability and international transparency appeal.

How Does USD Coin Work?

USD Coins are created through a process of minting. Users send USD to the USDC issuer's bank account, which then uses the USDC smart contract to create the equivalent amount of USDC. The digital currencies are then delivered to the user, with the fiat payment held in reserve.

Should the user wish to liquidate their USDC, they can send a request to the USDC issuer who then sends a request to the USDC smart contract to take a certain amount of USDC out of circulation. The issuer then sends the equivalent amount of USD (minus fees) to the user's bank account, taken from the reserve.

USD Coins can be traded through exchanges for other cryptocurrencies, or sent to crypto wallets around the world (provided that they support ERC-20 tokens). The coins are also often used to hedge against cryptocurrencies going through turbulent or crashing market periods.

What Is USDC?

USDC is a fiat-collateralised ERC-20 token hosted on the Ethereum blockchain platform. The stablecoin has an unlimited total supply with currently just under 37 billion USDC in circulation.

The coin provides an easy means of transferring funds internationally at a fraction of the cost and time that sending the traditional fiat would take. It has also proven to be a popular innovation in the DeFi (decentralized finance) space.

How Can I Buy USDC?

If you're looking to add USDC to your crypto portfolio you can do so conveniently through the Tap app. In a recent upgrade, the Tap app has added support for a number of prominent cryptocurrencies, including USDC.

Users can simply exchange one of the supported cryptocurrencies for USDC, or purchase USDC using fiat money. These can then be stored in the unique wallets integrated into your Tap account.

Le Litecoin fait partie de la toute première génération d’altcoins apparus après le lancement de Bitcoin. Cette cryptomonnaie pair-à-pair est aujourd’hui largement utilisée pour les paiements dans le monde réel, mais aussi comme actif dans les portefeuilles d’investisseurs. Depuis des années, elle reste solidement installée dans le top 15 des plus grandes cryptos par capitalisation boursière.

Lancé en 2011, Litecoin a été conçu pour offrir un moyen plus rapide d’envoyer de l’argent sur Internet, tout en restant complémentaire à Bitcoin. C’est pourquoi on l’appelle souvent "l’argent numérique", en écho au "Bitcoin, l’or numérique".

Litecoin est basé sur le code source de Bitcoin, mais avec quelques ajustements notables : un traitement des transactions bien plus rapide, des frais minimes, un algorithme de hachage différent, et un plafond d’émission plus élevé. Alors que Bitcoin a un maximum de 21 millions d’unités, Litecoin peut en produire jusqu’à 84 millions, avec un temps de validation des blocs réduit à 2,5 minutes contre 10 pour Bitcoin.

Le réseau a aussi été pionnier dans l’implémentation de technologies innovantes comme le Lightning Network et Segregated Witness (SegWit), qui ont ensuite été adoptées par Bitcoin.

Comment fonctionne le Litecoin ?

Litecoin utilise un mécanisme de consensus appelé Proof-of-Work (preuve de travail). Lorsqu’une transaction est initiée, elle rejoint un pool de transactions en attente. Les mineurs sélectionnent alors ces transactions, en vérifient la validité (soldes, adresses, etc.) et les incluent dans un bloc.

Le premier mineur à résoudre l’énigme cryptographique du bloc obtient le droit de le valider et reçoit une récompense en Litecoin. Cette récompense est divisée par deux tous les 840 000 blocs minés, dans un processus appelé halving, qui régule la création de nouveaux tokens.

Le réseau traite les transactions en moyenne toutes les 2,5 minutes, ce qui en fait un excellent choix pour des paiements rapides du quotidien. Les frais sont généralement de l’ordre de 0,03 à 0,04 $ US, rendant son usage abordable même pour de petites dépenses.

Litecoin et la technologie blockchain

Comme la plupart des cryptomonnaies, Litecoin repose sur la blockchain, un registre public et décentralisé. Chaque transaction est regroupée dans un bloc, vérifiée par les mineurs, puis ajoutée à la chaîne. Cela garantit la transparence et l’intégrité du réseau.

Grâce à la nature distribuée de la blockchain, aucun acteur unique ne contrôle les transactions sur le réseau Litecoin, ce qui renforce la sécurité et la confiance entre les utilisateurs.

D’où vient la valeur du Litecoin ?

La valeur du Litecoin dépend de l’offre et de la demande sur les marchés d’échange. Avec une offre limitée et une liquidité mondiale, il s’agit d’une cryptomonnaie dite déflationniste. Son adoption continue et son utilité en tant qu’actif numérique ont contribué à son positionnement solide au fil des années.

À quoi sert le Litecoin ?

Litecoin fonctionne comme un système de paiement numérique, à la fois moyen d’échange et réserve de valeur. Grâce à sa rapidité et à la fiabilité de son réseau, il est idéal pour des transactions du quotidien — comme acheter un café ou régler une addition au restaurant.

LTC est accepté par de nombreux commerçants et prestataires dans le monde, et son adoption dans l’écosystème crypto ne cesse de croître.

Qui a créé le Litecoin ?

Litecoin a été lancé par Charlie Lee, un ancien ingénieur chez Google et diplômé du MIT. Deux ans après avoir lancé le projet, il a rejoint une grande plateforme d’échange crypto en tant que directeur de l’ingénierie. En 2017, il est revenu à la tête du projet en tant que directeur de la Litecoin Foundation, une organisation à but non lucratif qui soutient le développement de la crypto et de sa technologie.

Développement de Litecoin et sa communauté

Le développement de Litecoin est assuré par une équipe dédiée de développeurs, qui améliore continuellement le protocole. Le projet est open-source, permettant à quiconque de contribuer à son évolution ou de proposer des améliorations.

Des mises à jour régulières sont publiées pour renforcer la sécurité, améliorer les performances et intégrer de nouvelles fonctionnalités compatibles avec les évolutions du secteur.

La communauté Litecoin est particulièrement active. Elle participe à la vie du projet à travers des retours, des propositions, du développement de code ou des initiatives communautaires. Cet engagement constant permet à Litecoin de continuer à se développer dans un environnement collaboratif.

‍

Il n’est jamais trop tard pour découvrir le nouveau système de paiement numérique. Bitcoin gagne en popularité chaque année, et à mesure que l’adoption s’accélère, c’est le moment idéal pour mieux comprendre la toute première (et toujours la plus importante) cryptomonnaie au monde.

Qu’est-ce que Bitcoin ?

Bitcoin est un système de paiement peer-to-peer qui fonctionne via Internet, sans passer par une autorité centrale comme une banque ou un gouvernement. Cette monnaie numérique permet d’envoyer de l’argent directement d’une personne à une autre, sans intermédiaires, sans frais bancaires excessifs, ni délais de traitement.

Contrairement aux monnaies traditionnelles, Bitcoin est géré par un réseau mondial d’ordinateurs, tous synchronisés par un protocole commun. Sa technologie de base, la blockchain, assure que chaque transaction est enregistrée de manière transparente, sécurisée et immuable.

Bitcoin fonctionne 24h/24, 7j/7, sans frontière ni restriction. Il est souvent comparé à l’or, car tous deux sont considérés comme des réserves de valeur fiables. Et même si la réglementation des cryptos continue d’évoluer, Bitcoin reste l’une des monnaies numériques les plus utilisées dans le monde.

Quels sont les avantages de Bitcoin ?

Bitcoin a introduit une nouvelle manière de gérer ses fonds — simple, transparente et indépendante. Voici quelques-uns de ses principaux avantages :

• Décentralisé : Aucune entité ne peut bloquer vos transactions, geler vos fonds ou exiger des démarches administratives complexes.
• Accessible : Il suffit d’une connexion Internet pour utiliser Bitcoin, où que vous soyez dans le monde.
• Transparent : Toutes les transactions sont enregistrées en temps réel sur une base de données publique, la blockchain.
• Liquide : Bitcoin est négocié sur des centaines de plateformes dans le monde entier, ce qui garantit une forte liquidité.

Comment fonctionne Bitcoin ?

Bitcoin repose sur la blockchain, une technologie qui permet à un réseau d’ordinateurs de traiter et valider les transactions sans intermédiaire. Voici comment ça marche :

Disons qu’Amal souhaite envoyer 1 BTC à Georges. Elle entre l’adresse du portefeuille de Georges et le montant dans son application Bitcoin. Chaque portefeuille contient une clé publique (visible par tous) et une clé privée (connue uniquement du propriétaire, comme un code PIN).

Une fois la transaction lancée, elle est ajoutée à un ensemble de transactions en attente. Des mineurs vont alors se concurrencer pour résoudre une équation cryptographique complexe. Le premier à réussir pourra valider la transaction.

Les fonds sont alors transférés d’Amal à Georges, et cette opération est enregistrée sur la blockchain. Ce registre numérique transparent mentionne la date, l’heure, les adresses concernées et le montant. L’historique est immuable et public.

Pour plus de sécurité, il faut souvent attendre trois confirmations (c’est-à-dire trois nouveaux blocs ajoutés à la blockchain) avant de pouvoir utiliser les fonds reçus.

Qu’est-ce qui donne de la valeur à Bitcoin ?

La valeur de Bitcoin repose sur l’offre et la demande. Son prix augmente quand la demande monte et que l’offre se raréfie.

Par design, Bitcoin est limité à 21 millions d’unités. Ce plafond intégré dans son code rend la cryptomonnaie naturellement déflationniste, à l’inverse des monnaies fiduciaires.

Avec sa progression remarquable au fil des ans, Bitcoin est devenu pour beaucoup un actif de long terme. Sa disponibilité permanente et sa forte liquidité renforcent encore son attrait auprès de ceux qui préfèrent "hodler".

À quoi sert Bitcoin ?

Bitcoin peut être utilisé comme moyen de paiement ou comme réserve de valeur. Son fonctionnement simple, sa disponibilité constante et la possibilité de le transférer partout dans le monde en quelques minutes en font une solution pratique.

De plus en plus de commerçants acceptent les paiements en Bitcoin, aussi bien en ligne qu’en boutique. Tant que vous avez Internet, vous pouvez envoyer et recevoir des BTC.

Quelle est l’origine de Bitcoin ?

Bitcoin a été annoncé publiquement le 31 octobre 2008, puis lancé officiellement en janvier 2009. Son créateur — toujours anonyme à ce jour — se fait appeler Satoshi Nakamoto. Il ou elle (ou eux) est à l’origine de toute la révolution crypto.

Dans le whitepaper du projet, Nakamoto explique avoir voulu créer une monnaie indépendante des banques et des gouvernements, en réponse à la crise financière de 2008. Une monnaie contrôlée uniquement par ses utilisateurs.

Vers 2010, Satoshi a disparu d’Internet, et son identité reste un mystère. Certains pensent même qu’il s’agissait d’un collectif.

Depuis, plus de 12 000 cryptomonnaies ont vu le jour. On parle alors d’altcoins (monnaies alternatives). Certaines, comme Ethereum, permettent de créer des applications décentralisées. D’autres, comme Litecoin, cherchent à améliorer le système de paiement de Bitcoin.

Comment acheter du Bitcoin ?

Acheter du Bitcoin est bien plus simple qu’on ne le pense.

Il vous suffit de créer un compte sur l’app Tap, de valider votre identité, et vous pourrez acheter des BTC en quelques clics. L’application vous donne accès à un portefeuille crypto sécurisé, à des échanges en temps réel, et même à une carte Tap pour dépenser vos cryptos comme des devises classiques.

Le staking liquide proposé par Lido permet aux utilisateurs de profiter des récompenses de staking sans perdre l’accès à leurs fonds. Le protocole soutient plusieurs cryptomonnaies basées sur le mécanisme de preuve d’enjeu (Proof of Stake, ou PoS) et offre une solution pratique : vos tokens sont mis en staking, vous touchez des rendements, et vous recevez en échange une version tokenisée de vos actifs que vous pouvez utiliser dans d'autres protocoles DeFi pour générer encore plus de rendement.

Qu’est-ce que Lido (LDO) ?

Lido DAO est une organisation autonome décentralisée (DAO) qui permet le staking liquide sur Ethereum 2.0 et d’autres blockchains PoS comme Solana (SOL), Polygon (MATIC), Polkadot (DOT) et Kusama (KSM). Le principe est simple : vous déposez vos tokens, et vous recevez une version tokenisée (1:1) que vous pouvez ensuite utiliser dans la DeFi, sans avoir à bloquer vos fonds.

Depuis son lancement en décembre 2020, peu après la sortie d’ETH 2.0, la plateforme est gérée par la DAO Lido avec des membres clés comme P2P Capital, KR1 et Semantic Ventures. Aujourd’hui, Lido gère plus de 13 milliards de dollars d’actifs en staking et se concentre principalement sur Ethereum, tout en s’ouvrant à d'autres blockchains comme Terra ou Solana.

Lido se distingue par sa nature décentralisée et ses rendements attractifs : par exemple, 4,8 % pour Ethereum, 8,1 % pour Terra, et 6,6 % pour Solana.

Qui a créé Lido DAO ?

Lido a été cofondé par Kasper Rasmussen et Jordan Fish (alias CryptoCobain). Parmi ses membres, on retrouve plusieurs acteurs majeurs du secteur DeFi comme Semantic VC, ParaFi Capital, Chorus, StakeFish, Libertus Capital, KR1 ou encore Terra. Des investisseurs de renom soutiennent également le projet, notamment Stani Kulechov (Aave), Banteg (Yearn), Julien Bouteloup (Stake Capital) ou Kain Warwick (Synthetix).

Comment fonctionne le protocole Lido ?

Le protocole Lido permet de mettre en staking ses cryptomonnaies tout en conservant leur liquidité. Lorsqu’un utilisateur stake ses actifs, il reçoit des tokens liquides appelés stAssets (par exemple, stETH pour Ethereum), utilisables dans d'autres protocoles DeFi comme des pools de liquidité ou des services de prêt.

Le contrat intelligent gère le staking, les retraits, les frais de récompenses, la délégation vers les validateurs, et l’émission ou la destruction de tokens.

Exemple avec Ethereum :

• Vous stakez de l’ETH → vous recevez des stETH en échange (1:1)
• Ces stETH continuent de générer des récompenses
• Vous pouvez les utiliser dans d'autres protocoles DeFi, sans immobiliser vos fonds

Il n’y a ni dépôt minimum, ni période de verrouillage.

Comment les récompenses sont-elles générées ?

Normalement, pour devenir validateur Ethereum, il faut déposer 32 ETH. Avec Lido, vous pouvez commencer avec une fraction de ce montant et recevoir des récompenses proportionnelles. Vos ETH sont répartis entre plusieurs validateurs sélectionnés par Lido DAO, puis déposés sur la Beacon Chain.

Cette répartition réduit les risques liés à un validateur unique et garantit une meilleure sécurité du réseau.

Le token LDO, à quoi sert-il ?

Le LDO est le token de gouvernance du protocole Lido. Il permet aux détenteurs de :

• Voter sur les décisions de la DAO
• Ajouter ou retirer des validateurs
• Gérer les frais de staking et leur distribution

Plus vous possédez de LDO, plus votre poids dans les votes est important. Le LDO a un supply total de 1 milliard de tokens.

Comment acheter du LDO et participer aux récompenses ?

Vous pouvez facilement acheter du LDO via l’application Tap. Une fois le token dans votre portefeuille, vous pouvez le conserver en toute sécurité ou l’utiliser sur la plateforme Lido pour générer des revenus passifs via le staking.

Téléchargez l’app Tap sur iOS ou Android pour commencer à explorer l’univers de Lido dès aujourd’hui.
