Crypto-Blogging
OpenTimestamps, IPFS, and NFTs for the blockchain era of blogging.
Since the end of 2020, the cryptocurrency market has gained, once again, mainstream attention. All-time high prices for Bitcoin and Ethereum, recognition of Decentralized Finance systems (DeFi), rise of Non-Fungible Tokens (NFTs), and more institutional investors jumping in the cryptocurrency market are some of the traits of the new cryptomania wave.
In this post, I will try to adopt some of the applications of these technologies, with the eyes of a researcher and (when I have time ) a blogger.
Blogpost Timestamping
A known application of blockchain-based Distributed Ledger Technologies
is trusted digital timestamping
OpenTimestamps is an open-source project that implements this idea. In particular, it uses Bitcoin block headers as time attestations: proof that a notary that we trust attested to the fact that some data existed at some point in time.
For bloggers, a timestamp of their blogposts would be useful to prove that
the post was not created after the date that the timestamper certifies.
For example, this post is timestamped using OpenTimestamps.
The timestamp is produced against the PDF version of the post.
The links to the PDF version and the timestamp file are reported in the header of the post.
Anyone can verify the correctness of the timestamp either
by using the CLI tool ots verify
,
or by relying on a third-party service like this.
I will try to keep this habit in the next posts.
As a reseracher, one could also timestamp PDF versions of his publications; however, it is less necessary as the published papers are already disseminated on the web by trustworthy (but centralized) aggregators, publishers, and search engines, e.g. Google Scholar, DBLP, ArXiv etc.
IPFS
The InterPlanetary File System (IPFS)
is a peer-to-peer distributed file system that seeks to connect
all computing devices with the same system of files
An entire website could be easily hosted on the IPFS network, like Juan Benet’s website, the creator of IPFS. All is needed is to either run a local IPFS node on your machine, or to rely on remote pinning services, like Pinata, to improve the availability of your files. At the moment, I have only uploaded some of my documents (see the IPFS links in publications page), but eventually I will run the entire website on IPFS, so to not rely on any third-party services.
Unstoppable Domains
Unstoppable Domains is a company building blockchain-based domains to replace cryptocurrency addresses with human-readable names. Being decentralized, such domains are inherently unstoppable (as long as the Ethereum blockchain and the transport layer it builds on are operational), and the sole owner is the owner of the private key associated with the domain. The system works thanks to the Crypto Name Service (CNS) built on Ethereum, and consists of a bundle of smart contracts. See the architecture documentation page for more details.
I set up my Unstoppable Domain marcofavorito.crypto that currently redirects to marcofavorito.me (see transaction here), hosted on GitHub Pages. I also have associated to it my email address, and my BTC and ETH addresses.
An easy way to navigate in the decentralized web is by means of this browser extension. If I had deployed the website on IPFS, I could have set up a redirection from my crypto-domain to the IPFS address of the website.
Blogposts as NFTs
Non-Fungible Tokens (NFT),
proposed in ERC-721
This post is associated to this NFT, that represents the ownership of this post. Who knows, it could be the next Beeple’s Everydays!
Conclusions
As a technology at its early stages, when it comes to applications of blockchain systems, the sky’s the limit. In this post, I wanted to play with several crypto-based services and see how they could be used for blogging.
Among other ideas not explored in this post, there are:
- Tokenize yourself as a professional/researcher/blogger. That is, make the token to represent something, material or immaterial, that you have or you can provide. For example, your working hours can be tokenized and then sold to people who’d like you to work for them, or to write the next blogpost . The token can be provided on DeFi exchanges like Uniswap.
- NFTs can be a way to post anonymously and still receive compensation for the work.
- NFTs allow for crowfunding writing in which an author can be supported in advance by contributors that in turn receive equity ownership from the writer’s work; everything coordinated by a smart contract in a trustless setting.
