verify ownership on-chain

Verify an OBJKT ID was issued by an address, by querying the on-chain data directly:

Take objkt ID, such as 72424 here: https://www.hicetnunc.xyz/objkt/72424
Place that into https://api.tzstats.com/explorer/bigmap/522/{id} such as: https://api.tzstats.com/explorer/bigmap/522/72424
Look at the "issuer" field and ensure the address matches exactly the profile you are trying to buy from.

e.g. My address is tz1XHADaUcMSkTN9gdmtRqcnrrZfs4tNkCPg and it matches, so we can verify that OBJKT has been minted by me.

Hicetnunc.xyz IPFS Pinning

💡 These steps will become easier, less technical, and more accessible as more open tools begin to emerge around Hicetnunc pinning. The steps below assume macOS but should work similarly across other platforms. This gist can be seen as a working draft toward more polished documentation; if you see any issues please post a comment below.

Basic Idea

Hicetnunc.xyz aims to be "decentralized" which means the OBJKTs are owned by the users, not the platform. So, in theory, if hicetnunc disappears, another marketplace could emerge on the same (user-owned) assets. But, this paradigm of decentralization means that you own the assets; so the responsibility to maintain them lies on the users, not the platform.

Of course, hicetnunc and some of its users will probably also make an effort to help maintain all the assets on its platform; but you should not rely purely on that, as it goes against the core ethos of dec

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

	// add script to a button inside Cryptovoxels to return a response

	feature.on('click',e=>{

	// Use GraphQL endpoint to pull data and make model that takes x,y Decentraland coordinates and returns prediction based on the latest 10 sales!

	fetch('https://api.thegraph.com/subgraphs/name/decentraland/marketplace', {
	method: 'POST',
	headers: {
	'Content-Type': 'application/json',

	query findSecondarySales($address: String = "tz1c2iwyckUCcicx2qxqtwLEartYFEHg1pvB") {
	hic_et_nunc_swap(where: {status: {_in: [1]}, token: {swaps: {trades: {buyer: {address: {_eq: $address}}}}}}, order_by: {price: desc}) {
	price
	status
	token {
	title
	mime
	description
	id

	# Uses ImageMagick to create an animated GIF from an image sequence and by using
	# a common palette.
	# Note: Providing a palette speeds up the encoding but can be disabled
	# by removing the “remap” option.
	# The resulting GIF is passed to “ImageOptim” for filesize reduction.
