Ep. 167 – Empowering individual’s consent using NFTs and blockchain – insights from Acoer

NFTs have been a cultural phenomenon throughout , constantly making headlines as celebrities dabble in the space and as shenanigans , scams , and legal fights ensue.

We have an entire explainer going into NFTs and the culture around them, as well as an explainer on the blockchain technology that NFTs use. NFTs, or non-fungible tokens, are digital tokens stored on the blockchain.

Rather, a link to the file is stored, along with the token that acts as proof of ownership over whatever that link points to. With that said If you just have the vague idea that you want to make an NFT because seemingly everyone is doing it, there are a few considerations you may want to take into account.

The first big one is transaction fees. You can pay more to give yourself a higher chance, but it is never a sure thing. To be clear, most transactions are likely to go through. Lazy minting lets you create an NFT and put it up for sale without it actually being written to the blockchain, thus avoiding any fees. When someone actually buys it, the fees for writing your NFT to the blockchain will be bundled with the fees to transfer it to the buyer. Both Rarible and OpenSea will take a 2.

There are, however, alternatives to the Ethereum blockchain. Both options have much lower fees than those you pay for using the Ethereum blockchain, if any fees at all, so we will at least touch on using them. While both platforms do let buyers add funds to their wallet to complete a purchase, having to convert or outright buy another cryptocurrency to nab your NFT may put some collectors off.

You can directly transfer Ethereum from its main blockchain over to Polygon and transfer back, but doing so will incur gas fees. Technically, no. You can create your own smart contract , deploy it to the blockchain of your choice, and then mint your own tokens using it.

Most people will want to use one of the platforms discussed above. Wallets are the applications you use to store your cryptocurrencies, as well as any NFTs you end up minting or buying. MetaMask will ask you to repeat the phrase back, while Coinbase Wallet will ask you if you want to store an encrypted copy of it on the cloud if you set it up using the app.

So seriously, keep your password and secret phrase safe. OpenSea and Rarible make this easy — clicking the Create button in the top left prompts you to connect your wallet. But if an unknown site asks to connect to your wallet, you should probably think twice before accepting.

Before we start creating our NFTs, a word on collections — both platforms support collections, which are pretty much what they sound like. You can also use the External Link field to add a URL pointing to, say, your website or Twitter account, and you can use the Description field to give potential buyers a better idea of what your NFT is.

However, all these fields are optional, so a lot of people will probably be able to ignore them. You could use this toggle-able field to include something like an invite link to a private Discord, a code to redeem something on an external website, or even just a message thanking them for buying. Like OpenSea, Rarible may ask you for a separate preview image for certain types of media, like videos or music — think of this as a video thumbnail or album art, which will display whenever your NFT shows up on the site.

This could be something like an invite link to a private Discord, a code to redeem something on an external website, or even just a message thanking them for buying. You then give your NFT a name — or title — and a description if you want. Finally, you can choose the royalty percentage. This will change how much of each subsequent sale goes back to you in the future. For example, if someone purchases your NFT for 0. The last option is the Advanced Settings, which lets you add properties to your NFT which is completely optional but could be useful if you were creating a series of characters with different properties and alternative description text, which will help make your NFT more accessible.

A new proof-of-work mechanism for bitcoin

These are the core obsessions that drive our newsroom—defining topics of seismic importance to the global economy. Our emails are made to shine in your inbox, with something fresh every morning, afternoon, and weekend. While at least 26 publicly traded companies hold bitcoin , just one owns more than half of all cryptocurrency on corporate balance sheets. The biggest corporate bitcoin holder is the Virginia-based business intelligence software maker MicroStrategy, according to a database from the crypto analytics firm CoinGecko. MicroStrategy bought its first tranche of bitcoin in August , citing worries that the US dollar would lose value thanks to the pandemic , financial stimulus measures from governments around the world, and global political uncertainty. Most publicly traded companies holding bitcoin already deal in cryptocurrency: They run exchanges, mining operations, or digital asset investment firms. But firms in unrelated industries are betting their balance sheets on the volatile asset class, too.
