STAMPS: A Protocol for Storing Images On-Chain in Transaction Outputs Immutably on Bitcoin
IMPORTANT NOTICE: STAMPS IS A BLOCKCHAIN-AGNOSTIC PROTOCOL.
FOR RULES SPECIFIC TO THE BITCOIN STAMPS PROJECT, PLEASE VISIT:


Storing "Art on the Blockchain" as a method of achieving permanence is often a misnomer in the NFT world. Most NFTs are merely image pointers to centralized hosting or stored on-chain in prunable witness data. We propose a method of embedding base64-formatted image data using transaction outputs in a novel fashion.

The means by which this is achieved is encoding an image's binary content to a base64 string, placing this string as a suffix to STAMP: in a transaction's description key, and then broadcasting it using the Counterparty protocol onto the Bitcoin ledger. The length of the string means that Counterparty defaults to bare multisig, thereby chunking the data into outputs rather than using the limited (and prunable) OP_RETURN. By doing so, the data is preserved in such a manner that is impossible to prune from a fullnode, preserving the data immutably forever.

Given the cost of preserving data in this manner, we suggest the following guidance: 24x24 pixel, 8-colour-depth PNG or GIF. The constraints of this "canvas" are ideal for pixel art. In particular, the CryptoPunks use a native resolution of 24x24 pixels.

STAMPS will be numbered based on the transaction timestamp. This is to ensure that the STAMPS directory is ordered chronologically. The first STAMP will be the first transaction to include the STAMP: string with a valid base64 string appended in the description key, and so on. A transaction with an invalid or indecipherable base64 string will not be considered a STAMP. The STAMP number will begin at zero and continue indefinitely.

VIDT DAO is a cutting-edge blockchain project that leverages timestamping technology to restore digital trust using its Web3 ecosystem. It operates as an open-source platform, using its unique blockchain technology to ensure the authenticity and integrity of data and documents. Using the VIDT DAO timestamping technology anybody can timestamp  any document or data, making its authenticity verifiable at any moment.

The core of VIDT DAO's offering is its $VIDT Utility Token, which facilitates the timestamping process. Each timestamp requires only 1 $VIDT, allowing all holders to seamlessly secure their digital documents. This simple yet powerful mechanism positions VIDT DAO as a vital player in the blockchain space, with over 25 real-life integrators already utilizing its technology.

MAGIC is the utility token that connects gaming communities in the Treasure Metaverse: a decentralized NFT ecosystem which sits on Arbitrum, one of Ethereum’s Layer 2 scaling solutions.

MAGIC is a cross-game currency that connects games, players, metaverses, and communities, all within Web 3.0. The token was launched in September 2021 so its community could buy and sell in-game NFTs on Treasure. It also acts as a reserve currency for Treasure’s metaverse.

Players can earn MAGIC tokens by gaming, mining, and participating in Bridgeworld, Treasure’s flagship game. Treasure now hosts twelve other games on its platform, some of which allow you to use and generate MAGIC tokens like in Bridgeworld. These include Beacon, a free-to-play fantasy action rogue-lite RPG; and Realm, a world-building and exploration game.

Arkham is a blockchain analysis platform that uses artificial intelligence (AI) to deanonymize the blockchain and on-chain data.

The platform’s two main components are the Analytics Platform and Intel Exchange. The Analytics Platform covers analytics on various entities, exchanges, funds, whales and tokens. For instance, you can check the portfolio holdings, transaction history, exchange flows, network relationships and other on-chain analytics. The Intel Exchange allows anyone to buy and sell address labels and other intelligence, either through bounties, auctions or the DATA Program.

Arkham uses an in-house AI engine with various sources of data, such as public records, social media, web scraping and user submissions. The data is used to label addresses and provide entity analytics for ULTRA, the company’s AI algorithm.

Arkham’s platform can be used for various purposes, such as tracking stolen funds, identifying fraudsters, verifying counterparties, auditing transactions, investigating hacks, and more. Arkham claims that its platform can help combat the proliferation of crypto crimes and scams by incentivizing on-chain research.

However, Arkham’s platform has also raised privacy concerns among some crypto users and advocates, who argue that deanonymizing the blockchain violates the principles of anonymity and censorship-resistance that underpin the crypto movement. Arkham has defended its platform by saying that it does not collect or store any personal data from users, and that it only provides publicly available information that can be verified on the blockchain.

Metis is an Ethereum Layer-2 scaling solution aiming to solve the blockchain trilemma: that blockchains cannot be decentralized, secure, and scalable simultaneously. It also strives to solve Ethereum's biggest challenges: speed, cost and scalability.

Metis wants to help developers create and manage existing decentralized applications (dApps), while also supporting developers and entrepreneurs who want to build and launch new dApps. It also integrates the Decentralized Autonomous Company (DAC) framework into its Layer 2 infrastructure to help developers and businesses move from Web 2.0 to Web 3.0.

Centrifuge is a decentralized asset financing protocol. It connects decentralized finance (DeFi) with real-world assets (RWA) while trying to lower the cost of capital for small and mid-size enterprises (SMEs) and provide investors with a stable source of income. The main goal of the project is to generate profits that are not tied to volatile crypto assets; the developers are pursuing the task of transferring real monetary value from fiat to cryptocurrencies.

Companies are using Centrifuge to access the liquidity that DeFi has to offer. They can tokenize real assets and use these tokens as collateral to access financing through Tinlake, a decentralized application (DApp) lending protocol. The Centrifuge blockchain is built on Polkadot (DOT) for speed and low fees, while its financial DApp Tinlake is built to access Ethereum (ETH) liquidity.

Centrifuge provides liquidity to everyone and investors receive income and rewards in the form of CFG tokens. Centrifuge links assets such as invoices, real estate and royalties with decentralized finance (DeFi). Additionally, borrowers benefit from the fact that they can finance their real assets without banks or other intermediaries.
