We May Think by Vannevar Bush A record if it is to be useful to
science, must be continuously extended, it must be stored, and above all
it must be consulted.

The
Anatomy of a Search Engine Currently, the predominant business
model for commercial search engines is advertising. The goals of the
advertising business model do not always correspond to providing quality
search to users. For example, in our prototype search engine one of the
top results for cellular phone is “The Effect of Cellular Phone Use Upon
Driver Attention”, a study which explains in great detail the
distractions and risk associated with conversing on a cell phone while
driving. This search result came up first because of its high importance
as judged by the PageRank algorithm, an approximation of citation
importance on the web [Page, 98]. It is clear that a search engine which
was taking money for showing cellular phone ads would have difficulty
justifying the page that our system returned to its paying advertisers.
For this type of reason and historical experience with other media
[Bagdikian 83], we expect that advertising funded search engines will be
inherently biased towards the advertisers and away from the needs of the
consumers.

Web5 notes
A block contains a list of claims and a list of parent blocks. In order to check if a block is valid, you also need a block with a claim “[blob] is a valid signature for [block]” and a copy of the signature. You can’t check a block’s validity in isolation.
When choosing among blocks to form a chain, choose the oldest. When choosing which of two conflicting blocks to remove in order to make a chain valid, remove the oldest. The older a block is, the more likely that other nodes will already have a copy.
