海外TECH	DEV Community	8 Best Blockchains that Support NFTs	https://dev.to/shtefcs/8-best-blockchains-that-support-nfts-199f	Best Blockchains that Support NFTs Best Blockchains that Support NFTsNon fungible tokens NFTs are the hottest digital investments out there today And people keep investing as the market grows Of course NFTs are cryptogenic assets and are only tradable in cryptocurrencies Hence they re only available in a blockchain Many more blockchain technologies keep supporting NFTs But whether or not you re new to NFTs our list of blockchains that support NFTs will give you a head start on which is worth your NFT venture Let s dive in right away EthereumEthereum is the earliest blockchain that supports NFTs Launched in Ethereum only falls in value behind Bitcoin the largest blockchain And it has a market cap of billion Indeed we ve seen many NFTs like Beeple Cryptopunk and more sell on Eth reaping millions of dollars for their creators Further it has a wide adoption among NFT traders And it s currently the biggest blockchain where people exchange NFTs and other cryptogenic assets Although Ethereum is reputable you might find its high gas fee unwelcoming ー this typically happens when more people transact at a time Indeed this has forced many NFT creators to opt for alternatives Nonetheless many marketplaces feature NFTs for sales in Eth Ultimately as Ethereum has gained ground in the crypto exchange market its value looks promising for the most part Some popular NFT Marketplaces that support Ethereum include OpenSea Rarible Nifty Gateway SuperRare and many others Ethereum Wallets MetaMask and Ledger are examples of wallets you can use to transact on the Ethereum blockchain ProsWidely adopted Many reputable NFT marketplaces support sales in Eth Value is rising Impressive market cap and NFT sales history The token is more stable and supported than other coins Interoperability with other blockchains It s a building block for many blockchains Many wallets support Eth ConsThe gas fee can be high Slow transaction time SolanaSolana launched in and has since never stopped gaining ground with NFTs It s notable for its faster transaction time and ability to accommodate high transaction volume coupled with low gas fees Solana s growth and adoption are impressive despite its recent launching In contrast to Ethereum Solana has a market cap of about billion and it s still rising And the blockchain trades in SOL Although it still pales behind in comparison to Ethereum many people take it as an alternative to Ethereum when trading NFTs Indeed we can safely accept that it s a top competitor of Ethereum As Solana is still a young blockchain dedicated NFT marketplaces for the platform keep springing But you ll still find a couple of reputable Solana NFT marketplaces to mint your digital assets To trade NFTs on top of the Solana blockchain wallets like Phantom CLV Slope Solflare and Math Wallet come in handy ProsLower gas fees Faster transaction rate Impressive growth and community support Ideal to start with if you re still new to NFTs Good community support Good support for NFTs Supported by many wallets ConsOnly a few reputable NFT marketplaces are currently available AvalancheAvalance is yet another blockchain that hits hard on the need for a fast transaction speed Moreover coupled with low gas fees Avalanche can run over transactions in a second Launched in it s one of the few recent blockchains with an impressive success record Avalanche trades in AVAX and as of mid March the blockchain has attained a market cap of billion At least at the time of writing its exchange value is up to per AVAX AvaxApes AvaxPunks ParticleCollections and more are NFT projects that reap the benefit of this blockchain And if you want to grab some fresh NFT mints on Avalanche you might want to look at marketplaces like NFTrade SnowFlakes YETI SWAP among others to sell your NFTs Avalanche wallet is the primary coin management platform that Avalanche provides for running AVAX based transactions However you can also use wallets like Ledger and Ledger Nano ProsLow transaction cost Fast and reliable Impressive value growth Good valuation and projections Interoperable with other blockchains ConsNo slashing protocol to check violations relating to frauds Binance Smart ChainBinance holds its reputation as one of the world s largest crypto exchange platforms The blockchain was launched in and has peaked in value up to per BNB It holds a spectacular market cap of more than billion Further the Binance Smart Chain is a subsidiary of Binance and runs together with the Binance Chain It uses Ethereum supported smart contract protocol to process transactions in BNB Binance Coins If you re looking for a way to exchange your NFT earnings without breaking into other apps you might want to stick with BNB NFTs Despite the high trading volume transactions on the Binance blockchain are superfast In addition to its dedicated NFT marketplace where you can mint and trade your collections Airnfts is also a notable BNF NFT marketplace For a choice of a coin wallet you might want to use MetaMask or Binance Chain Wallet NFT Projects like BakerySwap and Battle Pets use the Binance Smart Chain to process decentralized transactions ProsCompatible with Ethereum virtual machine EVM You can easily switch between blockchains Crypto exchange is easy The transaction is fast despite high trading volumes Rapidly evolving ecosystem Low transaction fees Stable BUSD available ConsMost of its backend functions hang upon Ethereum TerraLuna is Terra s cryptocurrency and the blockchain comes with a new goal in mind And that s to couple Fiat s stability with the volatility of cryptocurrencies One would wonder how Terra aims to achieve this as value fluctuation is one of the many attributes of cryptocurrencies But its goal result is evident in its immense support for many stable coins like UST Notably there weren t many activities on Terra between when it was launched and mid But its market value hit the market towards the end of when it started recording a market cap of over million At the time of writing Terra has a market cap of billion Undoubtedly the blockchain has received a wide range of adoption among investors Of course many upcoming and existing NFTs are available Galactic Punks and Luna Bulls are examples of top NFT projects on the Terra blockchain Marketplaces like Knowhere Art Gallery Breach gg and Luart io are notable for trading Luna NFTs Nonetheless Terra receives support from wallets like Trezor Ledger etc ProsFast transaction rates Lower gas fees Impressive growth rate and valuation Support for several stable coins ConsHave strict regulations Cardano Ada The light of Cardano beamed in And while it supports NFT trading its value growth hasn t been spectacular Further Analytics Insight projected that the value of Ada might rise to by Given a human look at the volatility of cryptocurrencies though ーwe can t be sure whether Cardano will rise beyond or even fall short of this projection But its security reputation and full support for the proof of stake protocol contribute to its projected bright future However Cardano fits the choice if you want to pay lower gas fees and transact faster as its transaction volume is low Galaxy of Art jpg store CNFT and Tokhum are notable marketplaces to mint Cardano based NFTs ProsCheap transaction fees Low volume of concurrent transactions It has credible security Support for proof of stake means you can stash your NFTs in the decentralized financial system and keep earning even without selling ConsValue is still poor Not so popularly adopted NEARNEAR is one of the recent blockchains that runs through a non carbon initiative Its popularity gained spectacular traction within a short time Since its launch in its market cap keeps climbing up the chart and currently flickers between billion and billion plus In value NEAR is even more credible than most launched before it Indeed this track record of wide adoption between investors makes it one of the most targetted potential spots for NFT investment NFT projects like Mintbase NFT HIPHOP and more are worth mentioning within the NEAR Cryptoverse Further Paras and Near NFT Club are popular marketplaces built upon the NEAR blockchain Here you can buy and mint NFTs based on NEAR exchange ProsIt supports the non carbon initiative Fast and efficient transaction protocol Few competitions due to lower transaction volume ConsA few NFT marketplaces are available FlowFlow is another blockchain you can leverage to sell your Non Fungible Tokens It s not surprising that Flow focuses on decentralized games apps and assets Besides the blockchain was developed by Dappa Labs the owners of CryptoKitties a popular NFT based game collection Despite only being launched in it records a market cap of over billion and exchanges for per FLOW at the time of writing This stat recorded a spike in October last year though And the market value went as high as billion With that said Flow also supports proof of stake protocol which lets you stash your coin on the blockchain and trade it whenever you wish This revolution of Flow s purpose around NFTs makes it an explicitly valuable tool for trading NFTs Want to transact your NFTs based on the Flow blockchain Look up to a marketplace like TopExpo ProsPrimarily built for NFTs Faster concurrent transaction time Intuitive platform It provides a framework of development for other decentralized apps and games It supports proof of stake protocol ConsYou ll have to pay a couple of transaction fees Conclusion Invest In a Profitable BlockchainThe need to add more value to the crypto world has brought about technologies like NFTs Decentraland and many others Unfortunately cryptocurrencies are volatile and keep fluctuating regardless of the blockchain Although experts might know the trend and invest in promising ones it s often futuristic gambling for beginners Generally a blockchain s gas fee might increase with high concurrent transactions And a lot more determines whether you should use a blockchain for NFTs However a blockchain s market cap growth history adoption gas fees transaction speed and more are indicators that it s worth your investment	2022-05-10 10:27:15
海外TECH	DEV Community	useMindMap	https://dev.to/benweier/usemindmap-1j3f	useMindMap Overview of My SubmissionuseMindMap is a mind mapping application backed by Appwrite It leverages Users Teams Database Realtime and Functions to provide a basic mind mapping service for yourself or a team Live Sign up sign in forgot password and team invitesPersonal and Team workspaces for your mind mapsCollaborative mind mapping powered by Appwrite RealtimeMind mapping functionality built on top of React Flow Building useMindmapThe first step was to deploy Appwrite I ve used Digital Ocean for some time and I love their single click app marketplace This got me a cheap droplet running Appwrite in about min Using an existing domain for testing purposes I set up a subdomain for the Appwrite instance played around with the admin console and thought Hell yeah this is awesome I created a Web project configured environment variables and did all the housekeeping necessary to prepare for full scale development After two days getting acquainted with Appwrite I was ready to build FRONTENDI started the frontend with a simple React project template webpack babel eslint typescript and blocked out the page routes I would need Home Auth sign in sign up etc Dashboard profile teams etc Mindmap maps Using inspiration from Chakra UI Pro and Tailwind UI I then created the sign up sign in pages and integrated with the Appwrite SDK to create a user and a logged in session The Dashboard followed with the sidebar and content Logged in user detailsMain activity viewProfile and Teams view Workspaces list and viewFrom some tinkering around with Appwrite s Database and SDK I settled on making each workspace a Collection and each Mindmap a Document with attributes name stringdescription stringnodes string edges string tags string After a couple weeks fleshing out the UI and getting intimate with the Docs and SDK I was finally tackling the MIIINDMAAAP spooky music When a user creates a mindmap for a given workspace a document is created in the associated collection and the user is launched into the maps id path Once inside the Mindmap view the React Flow instance is used to create nodes moved them around save a label attach edges and delete them React Flow represents its nodes and edges as objects with attributes like id position width height source target there are many many more properties but these ones are the important bits so they can be saved restored and propagated to other connected clients Each one of these events triggers a Function execution with a payload of the new value a node move event sends the updated position a label update sends a new data object etc From this point it s up to Appwrite Functions to resolve the mutation on the mindmap document Onward to the Backend BACKENDI wanted the concept of a group of mindmaps to be something the user or team doesn t even need to manage To support this using Appwrite Functions every user create or teams create system event creates a new collection only that user team has access to In effect this produces a scoped workspace of sorts for the user team to call their own and is entirely automatic As a side note I also use a Function to generate a gravatar URL for each user upon registration When a user opens a mindmap the client fetches the initial state of the document while also subscribing to document changes with the Realtime endpoint Realtime changes received by the client are then merged to the React Query cache to keep them in sync honestly React Query isn t even needed to push Realtime data from the callback response to React Flow but it s just so damn easy to use for handling server state that I can t not use it moving on With clients listening to documents for changes what s left is for Appwrite Functions to resolve updates to nodes and edges To do this I created two Functions to handle nodes and edges whose responsibilities are Accept the incoming payload from a HTTP eventPull the most up to date document from DatabaseInsert merge remove the changed attribute into from the original attributeSave the new document attributes back to DatabaseExit gracefully stage right grab a coffeeThis all seems like an oversimplification and while it s rather straightforward I did get inside my own head for a few days considering all sorts of funky solutions like CRDTs and custom WebSocket servers with Yjs I d like to thank the invaluable support offered by the Appwrite Team in the Office Hours channel on Discord Submission Category Web Wizards Link to CodeProudly open source on GitHub Additional Resources Info Tech StackAppwrite duh ReactDigital Ocean x droplet x static site app Key Dependencies React RouterReact FlowReact QueryReact Hook FormChakra UI Future PlansObviously this is a pretty quick n dirty mind mapper but I loved the experience of combining Appwrite with React Flow that I plan to take this further and develop it into a fully fledged app The mindmap experience right now is basic and rough and there s not a lot of expressive features to make a mindmap your own Having options like colours and shapes for the nodes at least as well as making editing seamless like opening the node edit panel above the selected node shortcut keys to add a pre linked node an automatic layout engine with elkjs would all go a long way	2022-05-10 10:23:43
