Proposal to solve the spam war: configurable data blob relay policy

The importance of proof-of-publication mechanisms, particularly within the context of blockchain technology, has been a subject of discussion and development over the years. Starting in 2013, significant contributions were made to understand and implement these mechanisms, with Bitcoin being highlighted as a premier platform for such activities. The utility of embedding data into the Bitcoin blockchain lies in its ability to serve as irrefutable evidence that the data has been observed by a substantial amount of computational power, essentially guaranteeing its wide dissemination and permanence. This characteristic makes Bitcoin an attractive layer for high-value applications, such as Citrea and Non-Fungible Tokens (NFTs), which demand robust security and universal accessibility to their published data.

Despite Bitcoin's proven effectiveness in this domain, there's an expressed interest in the exploration of alternative systems that may offer similar guarantees without necessarily matching Bitcoin's extensive security measures. For instance, Bitmessage emerged as an initiative to create a private messaging layer with some level of publication proof. However, its development stagnated, and the system suffered from significant operational issues, including the loss of previously published messages—highlighting the challenges faced by systems attempting to parallel Bitcoin's reliability over time.

For developers keen on innovating within this space, focusing on the cryptographic proof that ensures broad distribution of the published data is crucial. One suggested approach involves leveraging Bitcoin itself, by demonstrating that data is made valuable through a form of sacrifice and verifying the widespread publication of data through techniques like proof-of-possession. This could involve methodologies such as random sampling from a Merkle tree of previously published data to confirm its extensive reach. Such strategies underscore the need for a foundational level of proof to establish the viability and integrity of new proof-of-publication systems.
