What is blockchain?

A blockchain is a distributed database that is used to maintain a continuously growing list of records, called blocks. Each block contains a time stamp and a link to a previous block. A blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks and a collusion of the network majority.

Functionally, a blockchain can serve as “an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way. The ledger itself can also be programmed to trigger transactions automatically.” This makes blockchains potentially suitable for the recording of events, medical records, and other records management activities, such as identity management, transaction processing, and documenting provenance.

    • Alve Lundqvist We are sure you have such an impression because of Bitcoins which is the most famous thing about the Blockchain. The industry has moved much more further and now the technology is used not only by well-known banks as Deutsche BankHSBCKBC, one of Baltic States Estonia is planning to use it in securing its citizens’ medical data. Even more, Burger King in Russia launched their crypto-currency and it will be in blockchain ecosystem. Hope that convinced you that don't want to steal anyone's money!

  • Publica's main idea is that Blockchain tokens can represent something more than a record in the public ledger. We use READ tokens not only to prove your ownership of a copy of an ebook but also to grant you the actual access to ebook contents. E.g. you want to support your favorite author? Buy his book before it is written (and while it's cheap)! Once it is written your wallet & e-reader app will allow you to access book contents (while you have it in your wallet, e.g. own that book). After that or before that you can trade your tokens on an exchange, because these are well known ERC20 tokens. We want to give you just the same experience you get with paper books, you can sell them after you read them, or you can give them away etc, when you actually OWN something (this is what Blockchain is built for, right?) is opposite to have a license.

  • You know what!? I am taking a leap of faith and believing in this company and the blockchain/cryptocurrency concept. (I wish I could invest, but I wouldn't even know where to begin with that.) I truly believe this is the next logical step in an evolving ebook industry.

    I have been publishing my work in the ebook industry since 2006 -- back when the Big 5 were still snubbing ebook technology, and tech savvy readers were still reading off Palm Pilots. (Does anyone remember Fictionwise? lol. Or Microsoft  .lit files?) I wanted creative control over my work, so I avoided the traditional NY publishing route. You learn a lot when you lack resources and are forced to learn to do it yourself. For example, back in the day, it wasn't easy to find a book cover artist for ebooks--so you learned how to make a an e-cover.

    Anyway, at this point in my career, I can take a book from start to finish: I can write it, edit it, create a beautiful cover and all the associated promotional material, format the document for publication, convert the file into EPUB, EPUB3, Mobi, PRC, PDF and HTML formats, and upload these files to third party bookseller websites. I can also format and release a print edition. I can write copy and book descriptions, create author websites, write content for blog posts, and create graphics for all the social networks. However, I'm excited about the possibility being able to take my writing career to another level. Imagine all the writing I can do if there were other resources on hand?

    Anyway, I'm hopeful. :)
