What is Keep Network (KEEP)?

The Keep Network is a software aiming to incentivize a global network of computers to store private information that can be deployed on public blockchains via smart contracts. 

Many decentralized applications (dapps) running on public blockchains, like Ethereum, require the use of private data (such as health records, credit scores and financial information) to operate. 

To protect individual user’s privacy, the Keep Network enables private data to be stored outside the blockchain in “keeps”, which are containers that allow smart contracts to manage and use pieces of the stored data without exposing it to the public blockchain.

In order to operate a keep, nodes must stake KEEP tokens, Keep Network’s native cryptocurrency, to be selected by the Keep Network. These nodes are awarded KEEP for successfully maintaining keeps.  

The first application built on the Keep Network is tBTC, which serves as a bridge between Bitcoin and EthereumBitcoin holders deposit their BTC funds to a smart contract and receive tBTC, an Ethereum token of equivalent BTC value, used to access various dapps on the Ethereum blockchain.

Users seeking to stay up-to-date with the Keep Network’s progress can bookmark its blog. For more information on tBTC, you can read our “What is tBTC?” guide located in our Learn Center.
 

Who Created Keep Network?

Keep Network was founded by Matt Luongo and Corbin Pon in 2017. They previously co-founded Fold, a bitcoin shopping app, in 2014. 

Keep Network sold $20 million worth of KEEP tokens in two rounds in private sales to investors, which include noted venture capital firm Andreessen Horowitz, and noted cryptocurrency investors Polychain Capital, Fenbushi Capital and Paradigm. 

How Does the Keep Network Work?

Keep Network’s key feature is its ability to store private data, called secrets, outside the blockchain systems in keeps.

Keeps allow blockchain-based applications to interact with secrets without fully exposing their contents through the use of smart contracts, who, when a specific criteria is met, can provide data, encrypted files or verification of a user’s identity to the application.

Computers, or nodes, who maintain keeps are known as keep providers and are assigned fractions of a secret using the random beacon protocol, an advanced cryptography technique for trustless randomization.  

When a user wishes to purchase a keep, they publish a request to the Keep Network, who, in turn, divides and mixes their secrets, sends shares of them to different keep providers, and returns keys to the users to access the content of their keeps when needed.   

Keep providers must stake a certain amount of KEEP that can be retrieved by the protocol should they be unreliable or negligent with the keeps. However, providers incentivized through KEEP rewards for their services, including providing encryption, computation and storage services.

What is NEAR Protocol (NEAR)

NEAR Protocol is a smart contract capable, public Proof-of-Stake (PoS) blockchain that was conceptualized as a community-run cloud computing platform. Built by the NEAR Collective, NEAR was designed to host decentralized applications (dApps), and strives to compete with Ethereum and other leading smart contract-enabled blockchains like EOS and Polkadot. NEAR’s native token is also called NEAR, and is used to pay for transaction fees and storage. NEAR tokens can also be staked by token holders who participate in achieving network consensus as transaction validators.

NEAR Protocol is focused on creating a developer and user friendly platform. To accommodate this mission, NEAR has incorporated features like human-readable account names as opposed to only cryptographic wallet addresses, and the ability for new users to interact with dApps and smart contracts without requiring a wallet at all.

Projects building on NEAR include Mintbase, a non-fungible token (NFT) minting platform, and Flux, a protocol that allows developers to create markets based on assets, commodities, real-world events, and more.

NEAR Protocol Technology

As dApps have grown in popularity, the crypto community has faced a growing scalability problem. Scalability in this context refers to a blockchain’s ability to handle a large number of transactions with reasonable speed and cost. Ethereum has particularly faced scalability challenges due to the high demand for its usage, and while some people advocate for scaling solutions to be built on top of Ethereum (Layer-2 solutions), other projects like NEAR have decided to build entirely new blockchains with different architecture.

NEAR Protocol’s proposed solution to this scalability problem is the implementation of sharding. Before diving into what this means, it’s useful to identify the three main functions of blockchain nodes: they process transactions, communicate validated transactions and completed blocks to other nodes, and store the state and history of the entire network. As network congestion increases, these tasks become more and more demanding for the nodes.

Sharding lessens the computational load by splitting or partitioning the network into shards (or fragments). With this tactic, every node is not required to run all of the network’s code — just the code that’s relevant to its shard — so shards can conduct computation in parallel with one another, thereby scaling the network’s capacity as the number of nodes in the network increases.

To achieve consensus among the nodes in the network, NEAR uses a PoS system. With PoS, nodes who wish to become transaction validators must stake their NEAR tokens to be considered for participation. Token holders who do not want to operate a node can delegate their stake to validators of their choice. NEAR uses an auction system to choose validators every epoch (approximately every 12 hours), and validators who have larger stakes have more influence in the consensus process.

Some validators are responsible for validating “chunks” — an aggregation of transactions from a shard — while others are tasked with producing blocks, which contain chunks from all the shards. Other nodes, called “fishermen,” observe the network and detect and report malicious behavior. If a validator behaves badly, their stake will be slashed.

NEAR Token Economics

The NEAR token is primarily used to pay transaction fees and as collateral for storing data on the blockchain. NEAR also rewards several stakeholders in the blockchain with NEAR tokens. For their services, transaction validators receive a NEAR token reward every epoch that amounts to 4.5% of the total NEAR supply on an annualized basis.

Additionally, developers who create smart contracts receive a portion of the transaction fees that their contracts generate. The remainder of each transaction fee is burned, increasing the scarcity of the NEAR token. NEAR has also established a protocol treasury, which receives 0.5% of the total NEAR supply annually, for the purpose of reinvesting in the development of the ecosystem.

NEAR Protocol is capable of supporting tokens that are “wrapped” from other chains in addition to NFTs. Likewise, NEAR has constructed a bridge with Ethereum, allowing users to transfer ERC-20 tokens from Ethereum to NEAR.

NEAR Platform Governance

Resources allocated to the protocol treasury are distributed by the NEAR Foundation, a Switzerland-based non-profit dedicated to protocol maintenance, ecosystem funding, and guiding the governance of the protocol. Technical upgrades to the NEAR crypto network are carried out by the Reference Maintainer, which is selected by the NEAR Foundation board, though all nodes in the network must consent to updates by upgrading their software. Eventually, oversight of the Reference Maintainer will be conducted by community-elected representatives.

NEAR Protocol aims to pull ahead in the crowded race to provide the infrastructure for Web 3.0 and has sought to distinguish itself through its unique developer and user friendly features.

Where and how to buy NEAR?

If you want to get involved with NEAR or begin using any dapps built on the NEAR platform, then you’re going to need to get your hands on some NEAR tokens.

Though it’s possible to earn these by participating in development bounties, staking, and operating a NEAR community, the simplest way to get some is by buying it from a supported exchange platform—such as Binance, Huobi Global, or OKEx.

Below, we’ll cover how to buy these with Tether (USDT) on Binance—currently the most liquid exchange for NEAR.

Step 1: Register on Binance and top up your account with USDT or another supported asset. Right now, Binance supports conversions for NEAR against Tether (USDT), Bitcoin (BTC), Binance USD (BUSD), and Binance Coin (BNB).

Step 2: Head over to your designed NEAR market on the Binance spot exchange, e.g. NEAR/USDT or NEAR/BTC.

Step 3: Here, you’ll find the Binance trading interface. At the bottom of the page, select the ‘Market’ option from the order panel.

Step 4: Enter the amount of USDT you want to spend and click ‘Buy NEAR’—this will automatically execute your order at the best available price. Your NEAR will then be deposited to your Binance account balance, ready to withdraw or trade.

沃尔玛设立比特币ATM,实现门店购买比特币

在比特币创下新高之际,美国零售巨头沃尔玛(Walmart)已悄悄开始与Coinstar合作,在全美各地的数十家门市共设立200台比特币ATM(自动取款机),允许客户在门市内使用现金购买比特币。

沃尔玛计划,最终将在美国安装共8000台比特币ATM(也被称为BTM),但到目前为止,还没有关于推出时间的更多细节。

沃尔玛发言人莫莉布莱克曼(Molly Blakeman)表示:“Coinstar与Coinme合作启动了试点项目,在美国各地的沃尔玛门市里,已经有200台比特币ATM,它们都是试点项目的一部分。”Coinstar以其兑币机服务而闻名,它允许消费者用零钱硬币来兑换纸钞或礼品卡;Coinme则是一家提供用户购买和存储比特币的在线平台。

比特币ATM的购买流程是,客户将钞票插入ATM后,会拿到一张带有兑换代码的纸质凭证,而在兑换之前,需先建立Coinme的账户,并通过身份审核(Know your customer)。用户无法从他们的账户中提取比特币,也没有迹象表明在不久的将来会提供此功能。

根据Coinstar网站,每笔购买都需支付4%的交易手续费,另外还有7%的现金兑换费用。相比之下,币安和Coinbase对借记卡和信用卡购买加密货币分别收取3-4.5%和3.99%的费用,而从银行账户直接存款到币安或Coinbase钱包则是免费的。

根据Coin ATM Radar的数据,目前在美国共有超过2.5万台比特币ATM,Coinstar在33个州运营着4400台支持购买比特币的机器。

金融科技公司BitOoda的首席战略官兼研究主管Sam Doctor认为,虽然比特币ATM并不是一个新的发展,而且已经可以在许多超市找到,但“沃尔玛将比特币的使用范围扩大,并赋予它进一步的合法性”。

合规疑虑

尽管BTM的大规模推出可能预示着BTM将被广泛使用,但BTM设备供货商DigitalMint合规总监赛斯·萨特勒(Seth Sattler)指出,人们对于BTM可能助长洗钱也存在疑虑,因为有一些加密货币ATM营运商,对这些机器吸引相对高水平的非法活动视而不见

涉及BTM的诈骗活动也层出不穷,萨特勒透露,过去18个月以来,仅占BTM总交易额5%的DigitalMint,就返还了高达500万美元给诈骗的受害者。萨特勒认为,大型零售商需要了解他们正在与哪家供货商合作,以及该公司正在采取何种措施来管理风险。

用Defi平台炒币能否跨过国内监管

在中国严厉打击加密货币的压力下,众多中国投资者纷纷转向去中心化金融(DeFi)平台,因为它允许用户在没有任何中介(例如银行或经纪人)的情况下相互交易,而且不易被政府监管。据英国金融时报提供的数据,自去年6月起的1年间,中国近2650亿美元的加密货币投资中,就有高达49%来自去中心化金融平台。

监管打击造成交易量下降

中国自5月以来陆续祭出对加密货币的严厉监管措施,包含关闭比特币挖矿业务、勒令境内的加密货币交易所停业等,9月时更宣布交易加密货币为违法行为。

根据研究公司Chainalysis的数据,中国在全球比特币交易中的份额在2019年11月达到峰值15%,并在2021年6月降至 5%。

用户转向DeFi继续投资

专家表示,虽然最新的官方限制阻止了新用户进入加密市场,但一些现有的加密货币持有者正在转向DeFi继续交易。

中央财经大学金融科技研究中心主任Deng Jianpeng说:“由于禁令,大多数加密交易将停止,但总会有一些人会尝试寻找新的投资途径,比如使用海外平台或通过去中心化交易所。”

事实上,自中国于2017年首次禁止加密货币交易所开始,用户就逐渐转向DeFi。在截至今年6月的12个月中,中国大陆有2560亿美元与加密货币相关的活动,是亚洲地区最高的,其中49%是通过DeFi平台进行交易的。Chainalysis还表示,Uniswap是全球领先的DeFi交易所之一,现在按交易量计算是东亚第二大加密交易所。

复杂的获利手续吓退投资者

然而,中国投资者不能将在DeFi的收益转到中国的银行账户中,但对于有钱的中国人来说,这不是问题,因为他们能够将加密收益转移到海外的银行账户,并绕过资本管制限制。

对于一般人,51比特币论坛上的几篇帖子建议,可以注册一家海外公司并申请公司交易账户,还有人提供了一份英国和美国金融机构的名单,这些机构允许中国人开设银行账户,以便将加密投资收益转为法定货币。

但对于许多人来说,投资数字货币需要这么多麻烦并不值得,区块链公司SpaceChain的创始人兼首席执行官Zee Zheng说:“中国不会瞄准在法律边缘交易的那百分之一,对他们来说,监管能够阻止99%的交易,那就够了。”

DeFi与监管的拔河

在DeFi的世界里,并没有像传统交易所一样的身份审核(Know your customer)机制,普华永道加密货币负责人兼合伙人亨利·阿尔斯拉尼安(Henri Arslanian)表示,虽然使用DeFi“在中国可能被禁止,但实际上很难监控”,因为其用户是匿名的。

大型交易所Kraken的全球业务发展负责人Miha Grčar说,DeFi 是“加密领域的蛮荒之地(wild west)”,他补充说,但政府正在考虑如何对其进行监管,例如通过要求某种形式的用户身份识别。美国证券交易委员会主席Gary Gensler就曾警告说,监管机构希望对DeFi平台拥有更多权力。

经营推特账号Wu Blockchain的独立记者Colin Wu说:“许多中国人现在正在研究如何使用DeFi,但这也存在不确定性,因为美国政府希望加强控制。”

What is Curve DAO Token (CRV)?

Curve DAO (CRV) is the utility token of the Curve.fi DeFi protocol for exchanging stablecoins and other ERC-20 tokens. Curve’s main goal is to connect users who want to exchange ERC-20 tokens and stablecoins with exchange protocols. Curve’s financial platform is non-custodial, which means that users are in charge of their own tokens.

The system makes sure to enable low slippage and low fees by finding the best routes for users’ exchange requests. To achieve this system of exchanging, Curve uses liquidity pools which are backed with liquidity tokens. Liquidity pools encourage liquidity providers to deposit their tokens into the pools, to keep the price at satisfactory levels so they can benefit as well. Liquidity providers are rewarded for depositing their tokens into pools.

CRV is the protocol’s utility token and is used to incentivize liquidity providers, while holders can also use CRV to participate in network governance.

How Does Curve DAO Work?

The Curve DAO token powers the Curve.fi financial platform, which acts as an exchange and automated market maker. AMMs enable a different model of trading where assets can be exchanged permissionlessly and in an automated manner. Instead of relying on order books, trading is conducted automatically through liquidity pools.

Liquidity providers are incentivized to create pools and deposit tokens. Each pool contains certain token pairs which are supported within that liquidity pool. Pools contain similar assets to minimize impermanent loss and provide greater chances for returns.

The exchange market is based on liquidity pools, while the protocol connects users to various exchange markets to find the best fee rates. That way, Curve.fi ensures low slippage and enables traders to maximize their returns. Every time a network user makes a trade on the Curve network, liquidity providers are rewarded with a share of the trading fee for their participation.

Who Are the Founders of Curve DAO?

Curve DAO was founded and launched in 2020 and is one of the latest projects in the sector of decentralized finance. The Curve DAO Token was developed and created by Michael Egorov, a Russian scientist.

Michael Egorov has experience with blockchain and cryptocurrency companies, as he co-founded NuCypher and served as its CTO. NuCypher is focused on building privacy-oriented protocols and infrastructure.

What Makes Curve DAO Unique?

The Curve DAO token is a relatively new project that has already achieved great success thanks to its utility. Curve DAO experienced serious growth in the second half of 2020, providing users with low slippage and low fees for exchanging similar stablecoins and ERC-20 tokens.

Curve DAO is unique thanks to its technology and technical capacity, which makes Curve.fi an attractive exchange in the sector of DeFi. Instead of relying on order books, Curve forms liquidity pools based on smart contracts that work as an automated market maker. Users are connected with the best routes for their exchanges, while trading of tokens and stablecoins is conducted between traders and exchange protocols. Thanks to its technology and capacity to exchange tokens and stablecoins at the best rates, Curve has become synonymous with decentralized finance.

What Gives the Curve DAO Token Value?

The Curve DAO Token derives value from its technology, technical capacity, use cases, and mainstream use, i.e., popularity among crypto users and traders. The intrinsic value of CRV and Curve.fi is defined by its technology and features that enable traders to get low slippage and low trading fees for their exchanges. The overall functionality and utility are what provide Curve DAO Token with a real-life value. Factors such as upgrades, updates, developments, an increasing number of users and other important news and events can also affect the value of CRV and define its market value.

The intrinsic value often doesn’t match the market price of CRV. CRV is subject to frequent changes much like any other digital asset, except stablecoins which are pegged to fiat values. This is why CRV price can change dramatically in a relatively short period.

How Many Curve DAO Tokens (CRV) Are in Circulation?

There are currently 391,958,099 CRV in circulation out of a max supply of 3,303,030,299 CRV CRV. Curve DAO Token has a limited supply, much like Bitcoin, the original cryptocurrency. Cryptocurrency assets often limit the total supply of tokens to create an anti-inflation mechanism, which means they may be a good store of value in the long term.

Network participants may be able to propose changes to the total supply through decentralized governance of the network. The number of coins in circulation multiplied by the current CRV price equals the market cap. The market cap ranks the crypto in comparison with its peers and determines its market share.

Other Technical Data

Curve consists of liquidity pools that are created with smart contracts hosted on Ethereum. Many liquidity pools on the Curve.fi protocol are supplied to other liquidity protocols such as Compound. That is why liquidity providers may receive additional interest aside from the trading fees paid to the Curve.fi network.

When explaining the technical anatomy of liquidity pools, it is important to note that liquidity pools are actually smart contracts that contain tokens. If you were to create a pool with two similar tokens where the comparable value of these tokens is in a 1:1 ratio, DAI and USDC for example, when someone exchanges a certain amount of DAI for USDC, the USDC balance would be decreased by that amount. Despite the fact that there is less USDC, the difference in the amount would make USDC slightly less valuable in comparison. This mechanism encourages traders to exchange USDC for DAI, which is how the value will become even.

How is the Curve DAO Token Network Secured?

Curve DAO Token is secured through regular audits of smart contracts that are used for creating liquidity pools. The smart contracts are hosted on the Ethereum network while being operated by the Curve.fi protocol.

Curve DAO Token runs on the Ethereum network, which is currently transitioning from Proof of Work to Proof of Stake. PoS is a more cost-effective and energy-efficient protocol than PoW. CRV tokens can be staked and locked for voting to enable holders to participate in network governance.

How to Use Curve DAO Token

Curve DAO Token is the utility token of the Curve.fi protocol that powers the network. Curve.fi is used as an automated market maker and a decentralized exchange based on liquidity pools to allow users to easily swap tokens and stablecoins.

Curve DAO Token can be used as a governance token to take part in the voting process on the network but is also used as an incentive for network participants and liquidity providers. CRV can be traded in the crypto market, while traders may make a profit based on the difference between the buying and selling prices.

How to Choose a Curve DAO Token Wallet

As an ERC-20 token, CRV can be stored in any wallet that supports Ethereum and the type you choose will likely depend on what you want to use it for and how much you need to store.

Hardware wallets or cold wallets like Ledger or Trezor provide the most secure option for storing cryptocurrencies with offline storage and backup. However, they can require more technical knowledge and are a more expensive option. As such, they may be better suited to storing larger amounts of CRV for more experienced users.

Software wallets like Lumi provide another option and are free and easy to use. They are available to download as smartphone or desktop apps and can be custodial or non-custodial. With custodial wallets, the private keys are managed and backed up on your behalf by the service provider. Non-custodial wallets make use of secure elements on your device to store the private keys. While convenient, they are seen as less secure than hardware wallets and may be better suited to smaller amounts of CRV or more novice users.

Online wallets or web wallets are also free and easy to use, and accessible from multiple devices using a web browser. They are, however, considered hot wallets and can be less secure than hardware or software alternatives. As you are likely trusting the platform to manage your CRV, you should select a reputable service with a track record in security and custody. As such, they are most suited for holding smaller amounts of cryptocurrencies or for those making more frequent trades.

Buying and selling CRV, or trading it for any other cryptocurrency, is done in mere moments when you choose our secure platform as your storage solution.

Curve DAO Token Staking

Curve DAO Token can be locked into the Curve DAO to receive vote escrowed CRV, or veCRV. Holders of veCRV can participate in governance and receive staking rewards. Users can decide how much CRV to lock up and for how long, receiving more veCRV for locking up larger amounts for longer periods. Once the CRV is locked, these parameters can’t be changed.

Conclusion

Curve DAO and Curve.fi have become an important part of the decentralized finance sector in a relatively short time since the project’s inception in 2020. Curve.fi makes exchanging ERC-20 tokens and stablecoins easy and cost-effective as users can take advantage of some of the best fee rates and low slippage.

As the DeFi sector becomes more popular, Curve DAO might become an integral part of the growing crypto economy.

What is Fantom (FTM)?

Fantom is a decentralized, permissionless, open-source smart contract platform for decentralized applications (dApps) and digital assets — one of many blockchain networks built to provide an alternative to Ethereum. The Fantom blockchain mainnet went live in December 2019 and its network architecture intends to provide a viable solution to the blockchain trilemma by providing a steady balance of scalability, security, and decentralization.

Like other Ethereum alternatives, Fantom intends to provide more scalability and lower costs than the legacy first-mover smart contract platform is able to provide in its Ethereum 1.0 iteration. Fantom’s infrastructure is tied together through its Asynchronous Byzantine Fault Tolerant (aBFT) Proof-of-Stake (PoS) consensus mechanism, which maintains the operational efficiency of the entire network. The aBFT network structure is designed to preserve network security while maximizing speed.

Fantom Network Structure

Fantom operates atop a bespoke “leaderless” PoS consensus mechanism dubbed Lachesis that secures the Fantom network and ensures both transactional speed and security. Lachesis is an aBFT consensus mechanism, which means that network data can be processed at different times, and the network can tolerate up to one third of participants engaging in faulty or malicious behavior without causing undue harm to network processes.

Lachesis also boasts near-instant finality. This means that transactions are confirmed and finalized in an average of one second, without the need to wait for laborious block confirmation as experienced in Proof-of-Work (PoW) networks. By avoiding the relatively lengthy block confirmation process, this aBFT system is much faster and more scalable than many of its Byzantine Fault Tolerant (BFT) counterparts.

Diving deeper into how Fantom’s Lachesis functions, we see how each network node contains its own Directed Acyclic Graph (DAG), which records the chronology of “event blocks” and respective transactions, with each node achieving internal consensus independently. Confirmed batches of events blocks are then compiled into finalized blocks that are confirmed on the wider Fantom network. Finalized blocks, which form the base layer Fantom blockchain, are composed of confirmed event blocks from the independent nodes.

While independent Fantom nodes will occasionally communicate with one another about transactions and events, they do not confirm finalized blocks or the overall state of the network. This architecture results in a system that processes transactions quickly, and achieves finality within seconds. Fantom stresses that its PoS mechanism is leaderless, which means there are no block leaders and no participants have a special role in its operation. Anyone can join or leave the node network at any point, and all nodes hold equal weight in the consensus protocol.

Fantom Blockchain Mainnet: Opera 

The Lachesis consensus apparatus servers power Fantom’s mainnet deployment platform — Opera — which hosts dApps operating on the network. Opera is a permissionless and open-source environment for development. It boasts the full range of smart contract capability that Ethereum has due to its support of the Solidity programming language and integration with the Ethereum Virtual Machine (EVM). Applications built on Fantom can be designed to be interoperable with platforms built on Ethereum, while still maintaining the transactional efficiency of the Fantom network.

A proprietary software development kit (SDK) known as the Fantom Virtual Machine will eventually be released for native Fantom-based development alongside continued support for the EVM — a strategy meant to entice Ethereum-based dApp developers to make an easy transition over to building applications on Fantom.

Fantom Staking, FTM Token, and DeFi Suite

Fantom’s native utility token — FTM — powers the entire Fantom blockchain ecosystem. FTM tokens are used for staking, governance, payments, and fees on the network. There is a total supply of 3.175 billion FTM coins, with 2.5 billion in circulation as of March 2021. The remainder will be distributed as Fantom staking rewards. FTM is available as a native mainnet coin, an ERC-20 token in the Ethereum ecosystem, and a BEP-2 token in the Binance ecosystem.

Anyone can participate in Fantom staking with a minimum stake of 1 FTM by using Multichain to swap their ERC-20 FTM or BEP-2 FTM tokens for Opera FTM coins. Also, to operate a validator node on Fantom’s permissionless network at least 1 million FTM must be staked (valued at over $1 million USD as of March 2021).

Fantom provides a fairly dynamic and lucrative staking structure for users. Users can stake their FTM at-will with a validator node for a 4% annual percentage yield (APY) staking reward, which is a common staking model. However users can also take advantage of Fantom’s Fluid Rewards by choosing to lock up FTM for a predetermined period of time — ranging from two weeks up to a year — to secure higher reward rates up to 12% APY.

Fantom also employs a feature called Liquid Staking, whereby stakers can mint sFTM at a 1:1 ratio to their staked FTM to be used as collateral in Fantom Finance, which is a suite of DeFi apps provided by Fantom, thus allowing users to get more use out of their staked FTM. Some of the DeFi offerings that Fantom provides include:

  • fUSD: a Fantom-based stablecoin that’s pegged to the U.S. dollar 
  • fSwap: a synthetic asset decentralized trading platform
  • fLend: a liquidity pool from which users can lend or borrow

Fantom’s approach to the DeFi and dApp landscape is innovative — as is its staking reward program structure. Further proposed use cases for Fantom’s highly scalable smart contract platform are dApps related to supply chain management, payments, and smart city programs, some of which are already being piloted around the world.

As the first of its kind with its complex and unique infrastructure, Fantom’s approach to fast, scalable dApp development is still establishing its place in the wider blockchain ecosystem. Although there is already much competition in the burgeoning dApp sector, the speed and interoperability benefits that Fantom offers dApp developers are notable, and the platform is poised to gain further traction.

Coinbase currently doesn’t support Fantom trading. However Coinbase confirmed the integration of FTM and now the wallet enables users to carry out transactions in one second with near-zero fees. Over a million users have installed the wallet app and this integration will give them access to Fantom’s secure and fast DeFi ecosystem.

Fantom has extended Coinbase Wallet support within the Fantom fWallet. Users can sync their Coinbase Wallet account to their Fantom fWallet and conduct a number of activities such as stake FTM and earn rewards.

Coinbase Wallet users can easily access and use the Fantom network, and engage with a number of Fantom dapps. Coupled with the streamlined interface of the Coinbase Wallet, fast transaction speeds and low fees on the Fantom network ensure an excellent user experience.

VISA、NIKE将在北京冬奥会前接受数字人民币支付

中國正在推動麥當勞、Visa、耐克等美國大公司在明年北京冬奧會前接受數字人民幣的支付。

數字人民幣也被稱為E-CNY,是一種中國中央銀行的數字貨幣(CBDC),中國人民銀行在推出該項目方面遠遠領先於其他主要經濟體的同行。金融時報稱,麥當勞已經允許顧客在其上海的270家餐廳使用數字人民幣支付,但中國政府希望麥當勞將數字人民幣支付方式推廣到中國更多地方。一位熟悉情況的人士告訴金融時報,Visa和耐克也遇到了來自政府的壓力。

當商業內幕聯系麥當勞公司後,麥當勞表示它已向中國的顧客提供了一系列的支付選擇。“目前顧客可以在上海的麥當勞餐廳使用數字人民幣,這是我們的試點城市,我們將從顧客的反應中進行再調整。接受數字人民幣是在考慮顧客利益的情況下做出的商業決定,沒有任何壓力。”

當商業內幕聯系Visa時,Visa拒絕發表評論,而耐克公司則不願意發表評論。

三位熟悉情況的人士告訴金融時報,中國政府已經向美國公司施加壓力,要求它們安裝允許用數字人民幣付款的系統。這些消息人士告訴金融時報,中國的目的是確保數字人民幣支付系統在明年北京冬奧會開幕前可以投入使用。

斯坦福大學胡佛研究所(Stanford University’s Hoover Institution)開展的電子人民幣項目的聯合負責人達雷爾-達菲(Darrell Duffie)告訴金融時報:“大多數大型零售商將面臨提供數字人民幣支付的壓力,美國公司也不會被豁免。”

中國政府幾乎禁止了比特幣等去中心化的加密貨幣,限制了加密貨幣采礦和交易等活動。然而,中國也一直在大力推進官方的數字貨幣。自2019年以來,中國一直在試行數字人民幣。它進行了多次測試,包括向中國居民發放數字貨幣。據彭博社7月報道,數字人民幣的一項試驗已經積累了53億美元的交易額,這使中國比其他國家開發數字貨幣的努力領先了許多。

加拿大ETF已经领先美国

美国的加密货币投资者周二正在庆祝一个里程碑,因为纽约证券交易所的第一个比特币ETF正式交易。实际上,加拿大比美国已经领先了一段时间,它们早就为美国投资者提供了比特币ETF的选择。

周二在纽交所上市的是ProShares公司基于期货合约的比特币策略ETF(BITO)。然而,期货合约并不总是很好地追踪比特币的实物价格,美国证券交易委员会(SEC)到目前为止还没有批准一个直接持有实物比特币的ETF。

加拿大监管机构今年早些时候批准了直接持有比特币的ETF。第一个加拿大比特币ETF在2月由Purpose Investments推出,在多伦多证券交易所进行交易,该ETF以加元计价的交易代码为BTCC.B、以美元计价的交易代码为BTCC.U。

Purpose Investments的创始人兼首席执行官Som Seif说:“正式的ETF结构规定了每日的流动性和每日的标价以及做市商,他们唯一的工作是确保ETF的价格和ETF的净资产价值直接挂钩,并以这种方式全天交易。如果投资者只是持有比特币相关的期货和展期期货,随着时间的推移,它会有表现不佳的风险,因为它的价格是期货价格,而不是当前价格。”

另外,Evolve公司在也推出了ETF,加元交易代码为EBIT,美元交易代码为EBIT.U。CI Galaxy公司也有比特币ETF,加元交易代码为BTCX-B,美元交易代码为BTCX-U。加拿大的Greyscale公司持有一个信托(GBTC),实际持有比特币资产。由于信托结构可能会导致基金的净资产价值和比特币价格之间的差异,周二,Greyscale公司申请将其转换为ETF。

然而,Nimbus DeFi资本市场副总裁Waseem Mamlouk说,有许多因素可能会阻碍美国投资者投资加拿大的比特币ETF。Mamlouk说:“围绕着实际资产通过外资投资公司为他们进行交易的想法,可能会有托管方面的担忧。目前一直存在与加密货币托管有关的安全问题,所以这将是最突出的脏耐。当然肯定还有其他原因,包括访问的便利性。”

在加拿大,还有一些以太坊ETF的投资,如(ETH)、(ETH-U)、(ETHR)、(ETHR-U)、(ETX-B)、(ETX-U);以及比特币和以太坊的组合(ETC)、(ETC-U);甚至还有一个反向比特币ETF来赌比特币看跌(BITI)。

What is FLOW (FLOW)?

  • Created by NBA Top Shot developer Dapper Labs, Flow is a proof of stake blockchain designed for NFT collectibles and crypto games.
  • Dapper’s CryptoKitties clogged up Ethereum in 2017, prompting the development of Flow as an alternative.

When CryptoKitties, one of the very first non-fungible token (NFT) projects, brought the Ethereum blockchain to a halt in late 2017 due to immense congestion, developer Dapper Labs learned firsthand that current-gen blockchains weren’t built to handle such demand.

With NFTs—provably-unique tokens that can be linked to digital content—becoming increasingly popular, something needed to be done.

Rather than simply find another home for its decentralized app (dapp) or wait for Ethereum scaling solutions to mature, Dapper decided to build the kind of blockchain that it and other developers could rely on.

The result is Flow, a blockchain purpose-built to support things like NFT collectibles and large-scale crypto games.

CryptoKitties will soon migrate to Flow, and with the surging success of Dapper’s NBA Top Shot, and many other developers signing on to build with Flow amidst the NFT boom, it could prove to be one of the leading blockchains for such creations.

Here’s a look at what Flow is, how it works, and how to get ahold of the FLOW token.

What is Flow?

Flow is a blockchain that is designed for extensive scaling without the use of sharding techniques, providing fast and low-cost transactions that make sense for dapps such as NFT marketplaces and crypto-infused video games.

As mentioned, Flow hails from Dapper Labs, which decided to solve its blockchain congestion problem head-on by building one primed for games and other interactive experiences. Dapper is now using Flow for all of its own projects, including NBA Top Shot, but it’s open to other developers as well.

How does Flow work?

Flow uses a proof of stake consensus mechanism that requires validators to stake a certain number of FLOW tokens to participate in the network.

However, the way that validation works is unique amongst blockchains, as Flow splits validation tasks into four separate types of nodes: consensus, verification, execution, and collection. All four node types participate in the validation of each transaction.

Dapper says that splitting up the tasks makes processing transactions more efficient than on rival blockchains. It’s an alternative option to sharding, or spreading out the storage and computational needs of a blockchain across numerous nodes. Flow does not use sharding, and by doing so, Dapper says that Flow keeps transactions atomic, consistent, isolated, and durable (ACID), and allows developers to build on each others’ work.

Flow also features upgradeable smart contracts, allowing smart contracts to be deployed in beta and then enhanced or fixed before being finalized and made immutable.

Did you know?

CryptoKitties will migrate from Ethereum to Flow, with Dapper promising new features for the breedable digital cats as well as use in future games running on Flow.

What’s so special about Flow?

Flow is built for the kind of collectible and interactive crypto experiences that are quickly growing in prominence, and could find much larger audiences in the years to come. NBA Top Shot has already demonstrated the potential for a blockchain-driven collectibles experience to generate huge sums of cash and find major mainstream attention. That’s just one experience built on top of Flow, with many more to come.

Flow + NBA + UFC

NBA Top Shot has already been an enormous success, but Dapper Labs has other high-profile partners in its stable, including the likes of Ultimate Fighting Championship (UFC)CNN and Dr. Suess. Besides those brands, Dapper also has partners like gadget giant Samsung, game publisher Ubisoft, and Warner Music Group.

What can you do with Flow?

Right now, as a user, you can interact with Flow via NBA Top Shot or by buying artwork from the VIV3 NFT marketplace, as well as other working apps built on the blockchain. Developers can begin using the various built-in tools to experiment with Flow and start building their own dapps.

Did you know?

Dapper Labs raised a $12 million investment round in August 2020 that featured participation from several current NBA players, including Andre Iguodala and Spencer Dinwiddie.

Where to buy FLOW

Flow’s native FLOW token was initially offered to the public in October 2020 through CoinList, but was unavailable within the United States and Canada. Tokens sold through the offering were locked up for at least a year thereafter, which means they can’t be circulated until they’re unlocked.

On the other hand, FLOW rewards paid to validators can be transferred and sold, so there is some FLOW out on the market, and some exchanges—like Kraken and Huobi—let users transact FLOW. However, major exchanges like Coinbase do not currently handle FLOW. Binance recently listed FLOW.

The future

NFT collectibles blew up in a big way in late 2020 and early 2021, and Flow has been one of the biggest beneficiaries of that surge. Not only has Dapper Labs’ own NBA Top Shot been one of the most successful crypto dapps, but Flow reported a significant uptick in developer requests during the early weeks of 2021. In short, NBA Top Shot has been a successful proof of concept for Dapper’s custom-built blockchain, and now other developers want to tap into that infrastructure.

With developer interest comes commercial interest, too; in June 2021, NFT marketplace Rarible, which has to date focused on Ethereum-based NFTs, announced that it would expand its offering to Flow with the proceeds of its $14.2 million Series A fundraising round. Dapper has its own additional collectibles platforms in the works, as well.

Flow’s also building out its infrastructure. In June 2021, Dapper Labs launched FUSD, which it described as the first U.S. dollar-backed stablecoin on Flow; the stablecoin is backed one-for-one by U.S. dollars deposited at financial infrastructure provider Prime Trust.

That’s part of Dapper Labs’ wider ambitions for Flow, which envisage it being used for more elaborate game experiences beyond NFTs: Dapper calls it the “blockchain for open worlds.” On one hand, “open” implies decentralization—but it may only be a matter of time before it plays host to large-scale crypto games, as well.
