|

# substr($0, length($0), 1)

- go over the paper to make sure we use active voice in most places (though passive is better sometimes)
|

- standardize when we say "we do X" vs "LBRY does X"
|

- check that all anchors work
|
||||
- check css across browsers/mobile
|
||||
- create links for [[terms]]
|
||||
- ensure that all italicized terms are defined before they are used, or if that doesn't work, that they are linked
|
||||
- don't say "the LBRY network". instead say "LBRY" or say nothing.

#### Design Notes
|
||||
|
||||
The most contentious aspect of this design is the choice to resolve names without modifiers (sometimes called _vanity names_) to the claim with the highest effective amount. Before discussing the reasoning behind this decision, it should be noted that _only_ vanity URLs resolve this way. Permanent URLs that are short and memorable (e.g. `lbry://myclaimname#a`) exist and are available for the minimal cost of issuing a transaction.

Permanent URLs that are short and memorable (e.g. `lbry://myclaimname#a`) exist and are available for the minimal cost of issuing a transaction.
|
||||
|
||||
LBRY's resolution semantics stem from a dissatisfaction with existing name allocation designs. Most existing public name schemes are first-come, first-serve with a fixed price. This leads to several bad outcomes:
|
||||
|
||||
1. Speculation and extortion. Entrepreneurs are incentivized to register common names even if they don't intend to use them, in hopes of selling them to the proper owner in the future for an exorbitant price. While speculation in general can have positive externalities (stable prices and price signals), in this case it is pure value extraction. Speculation also harms the user experience, who will see the vast majority of URLs sitting unused (c.f. Namecoin).
|
||||
|
||||
2. Bureaucracy and transaction costs. While a centralized system can allow for an authority to use a process to reassign names based on trademark or other common use reasons, this system is also imperfect. Most importantly, it is a censorship point and an avenue for complete exclusion. Additionally, such processes are often arbitrary, change over time, involve significant transaction costs, and _still_ lead to names being used in ways that are contrary to user expectation (e.g. [nissan.com](http://nissan.com)).

|
||||
|
||||
3. Inefficiencies from price controls. Any system that does not allow a price to float freely creates inefficiencies. If the set price is too low, there is speculation and rent-seeking. If the price is too high, people are excluded from a good that it would otherwise be beneficial for them to purchase.

Each opcode will push a zero on to the execution stack. Those zeros, as well as any additional parameters after the opcodes, are all dropped by `OP_2DROP` and `OP_DROP`. `<outputScript>` can be any valid script, so a script using these opcodes is also a pay-to-pubkey script.

A distributed hash table is a key-value store that is spread over multiple nodes in a network. Nodes may join or leave the network anytime, with no central coordination necessary. Nodes communicate with each other using a peer-to-peer protocol to advertise what data they have and what they are best positioned to store.

When a host connects to the DHT, it announces the hash for every [[blob]] it wishes to share. Downloading a blob from the network requires querying the DHT for a list of hosts that announced that blob’s hash (called _peers_), then requesting the blob from the peers directly.

|

#### Querying the DHT
|
||||
|
||||
Querying works almost the same way as [[announcing]]. A client looking for a target hash starts by sending iterative `FindValue(target_hash)` requests to the nodes it knows that are closest to the target hash. If a node receives a `FindValue` request and knows of any peers for the target hash, it responds with a list of those peers. Otherwise, it responds with the closest nodes to the target hash that it knows about. The client then queries those closer nodes using the same `FindValue` call. This way, each call either finds the client some peers, or brings it closer to finding those peers. If no peers are found and no closer nodes are being returned, the client determines that the target hash is not available and gives up.
