Compressed XCP Transactions

This is a draft proposal for compressed Counterparty messages. The benefits will be: slightly reduced fees for ordinary XCP transactions. significantly reduced fees when bundling several XCP messages in one BTC tx. First let’s look at a typical Counterparty message: 434e5452505254590a000000000000000100000000ee6b28000000000001d6b896000000000bebc2001f800000000000000000 Prefix The first eight bytes, 434e545250525459, is the prefix. It translates to CNTRPRTY. All Counterparty transactions use this prefix. My proposal suggests an alternative prefix, 584350, meaning XCP. This […]

I suggest changing it to something like this: easyasset.art/j/24lf1HKGp_V3q5Jj5lMx.json This URL contains a hash. It makes the NFT permanent. Why it Matters EasyAsset repeats an old mistake made by Monegraph in 2014. Like many modern NFTs, MGAAAAAAAAAAA‘s metadata is a link to a json file. Open it and […]

OLGA on Dogeparty has all associated info in a json file. The only onchain data is a URL: olganft.com/i/olgaGzrKnjmRW6jrCoNo.json A simple link, yet sufficient to make the token perfectly immutable. Even if the .com domain expires, the NFT can be recreated by anyone with a copy of the associated files. Background & Update In 2014 I minted 1001 OLGA tokens.

SALVATION (2015) – Practical Joke NFT

Sometime 2015 I minted a few SALVATION tokens, made an anonymous announcement, leaned back and enjoyed the reactions. The Conception On August 4, 2015 I issued 7 indivisible SALVATION tokens with description: “SAVE UR SOUL FROM SIN & ITS CONSEQUENCES” A couple days later I transferred the issuance-right to 1SaLvationGodsMarveLousGracaLgYQS. If, by a miracle, this address has a private key, salvation can be bestowed upon every soul on the planet. […]

List of Historic NFTs With Scarce Initial Supply

This article is about Economic Grails – Historic NFTs that had their tokenomics set in stone already in 2014/15. In 2014 Counterparty jumpstarted the p2p economy by introducing custom ‘crypto currencies’ – or ‘crypto assets’ – on the Bitcoion blockchain.

Thousands of assets were created […]
