Proof-of-publication systems are gaining attention in the blockchain industry as a solution to the double-spend problem. These systems utilize various proofs, such as proof-of-receipt, proof-of-non-publication, and proof-of-membership, to ensure the integrity of transactions. One example of proof-of-publication is the Torrens Title System, which operates similarly to the Bitcoin blockchain.However, there are some misconceptions surrounding proof-of-publication that need clarification. First, it should not be mistaken for timestamping, as it involves more than just adding a timestamp to a document. Additionally, it is not easily censorable and can be made expensive if necessary. Despite these misconceptions, proof-of-publication offers a practical solution and has applications beyond just timestamping.One advantage of proof-of-publication is that it does not bloat the blockchain like other systems, avoiding significant increases in transaction fees. However, some systems do contribute to the growth of the Unspent Transaction Output (UTXO) set, which may impact fees. The use of proof-of-publication systems in Bitcoin can also have varying effects on the cryptocurrency's price, depending on the specific use-case and features introduced.While proof-of-publication systems may seem inefficient from the perspective of simplified payment verification (SPV) clients, they provide accountability for trusted third parties. They address the issue of global consensus inefficiency in Bitcoin's architecture. Some proof-of-publication systems require limited-supply tokens, but whether these tokens are considered "scamcoins" is a subjective question. They serve technical purposes in enabling secure client-side validation and do not necessarily need to appreciate in value compared to Bitcoin. Furthermore, not all use-cases of proof-of-publication involve tokens or finance.In a 2014 email exchange, Peter Todd argued that using a limited-supply token in a proof-of-publication system enables secure client-side validation. This contrasts with the alternative of 2-way-pegging, which relies on trust in miners not to steal pegged funds. However, another participant challenged the notion of "secure" and "client-side validation" going hand-in-hand. They emphasized the importance of considering a transaction valid in the wider world and highlighted the value of validated data in the blockchain for distributed consensus.In conclusion, proof-of-publication systems offer practical solutions to the double-spend problem and have various applications. Misconceptions surrounding these systems need clarification, and scalability improvements are necessary to mitigate any negative impacts on Bitcoin's price. While they may be inefficient for SPV clients, they provide accountability for trusted third parties. The use of limited-supply tokens in these systems can enable secure client-side validation, but opinions on their classification as "scamcoins" differ. It is important to note that not all proof-of-publication use-cases involve tokens or finance.
