The problem PageDAO Books solves

The NFT Book market is fragmented and siloed to separate blockchains. While there are many creator profiles and marketplaces, there is no singular location to find all things literary. We wanted to create a hub for literary activity that provides:

Censorship Resistance
Decentralized encrypted and gated content
Private purchase, lending, and selling
Secure royalties
Multichain markets
Crowdsourced quality assurance for content

Challenges I ran into

We wanted to create a chain-agnostic and frictionless social login that allows authors to seamlessly create profiles that automatically update with their onchain activity. This required finding a web3auth provider that supports multiple chains and smart contract/account abstraction wallets. We ended up using a conglomeration of tools including dynamic.xyz and magic.link.

While there are many token gating solutions, most are chain-specific and require a third-party host/api to remain available to access the underlying asset. We wamted to bring the rights management closer to the chain so the content would survive any one organization's hostname. To solve this problem, we looked at privacy-chains in the cosmos ecosystem. While Namada looked promising, it was still early in testnet phase. We ended up working with Secret Network using Privacy-as-a-Service (PaaS). The concept we came up with is a sister-contract that exists on Secret Network for each asset with protected data on a variety of other chains.
