This means that each satoshi (the smallest unit of bitcoin) can have its own unique identity and meaning through these inscriptions.

For example, let’s say you want to create an NFT of a picture of your cat. Instead of storing this image off-chain like traditional NFTs on other blockchains, with Ordinals protocol you would actually embed the data within a Bitcoin transaction using an inscription. This means that not only is the metadata stored directly on the Bitcoin blockchain (making it more secure and decentralized), but also each satoshi used to pay for this transaction can have its own unique identity through the inscription.

Recently, several Ordinals collections have gained popularity, such as “On The Edge Of Oblivion” which bridges ETH NFTs to Bitcoin NFTs and has recorded 1,158 sales in the last week alone. Another collection called “Bitcoin Orbs” is also gaining traction, clgoaling to be the first Manifold NFT Edition on the Ordinals protocol. These collections allow for unique identities and meanings to be embedded within each satoshi used to pay for transactions using inscriptions, making them more secure and decentralized than traditional off-chain storage methods.

In terms of the specific context provided, this article discusses a recent paper by Yackolley Amoussou-Guenou et al., “Committee-Based Blockchains as Games between Opportunistic Players and Adversaries,” which was published in The Review of Financial Studies (June 2023). This research explores the use of committee-based blockchain systems, where a group of nodes is responsible for validating transactions. By modeling this system as a game between players with different incentives, the authors are able to analyze its security and efficiency properties in various scenarios.

In contrast, Arbitrum’s “Nitro” upgrade goals to improve the scalability and performance of their layer-2 Ethereum scaling solution by introducing several new features such as a faster execution engine, improved storage architecture, and optimized data availability protocols. These changes are expected to significantly reduce gas costs for users while maintaining high levels of security and decentralization.

Overall, the Ordinals protocol is a pretty cool development for the crypto world since it allows for NFTs to be created directly on the Bitcoin blockchain without sacrificing security or decentralization. And with over 58 million inscriptions already minted as of January 2024, it’s clear that this technology has caught on quickly and is here to stay!
