  1. A DHT is a hash table that partitions the keyspace and distributes the parts across a set of nodes. For any new content added to the network, a hash (k) is calculated and a message is sent to any node participating in the DHT. This message is forwarded from node to node until it reaches the node responsible for k.

  2. ... The key feature of the Cosmos Blockchain is its attempt to provide a solution to one of the major challenges in the blockchain space: the lack of interoperability. Cosmos is specifically designed to enable different blockchains to communicate, share data, and transact with each other.

    The simplest topology is a permanent link between two endpoints. Switched point-to-point topologies are the basic model of conventional telephony. The value of a permanent point-to-point network is the value of guaranteed, or nearly so, communications between the two endpoints. The value of an on-demand point-to-point connection is proportional to ...

    - Linear Bus: The type of network topology in which all of the nodes of the network are connected to a common transmission medium which has exactly two endpoints (this is the 'bus', which is also commonly referred to as the backbone, or trunk) – all data that is transmitted between nodes in the network is transmitted over this common transmission m...

    The type of network topology in which each of the nodes of the network is connected to a central node with a point-to-point link in a 'hub' and 'spoke' fashion, the central node being the 'hub' and the nodes that are attached to the central node being the 'spokes' (e.g., a collection of point-to-point links from the peripheral nodes that converge a...

    The type of network topology in which each of the nodes of the network is connected to two other nodes in the network and with the first and last nodes being connected to each other, forming a ring – all data that is transmitted between nodes in the network travels from one node to the next node in a circular manner and the data generally flows in ...

    The value of fully meshed networks is proportional to the exponent of the number of subscribers, assuming that communicating groups of any two endpoints, up to and including all the endpoints, is approximated by Reed's Law. - Fully Connected: The type of network topology in which each of the nodes of the network is connected to each of the other no...

    (also known as Hierarchical): The type of network topology in which a central 'root' node (the top level of the hierarchy) is connected to one or more other nodes that are one level lower in the hierarchy (i.e., the second level) with a point-to-point link between each of the second level nodes and the top level central 'root' node, while each of t...

  3. 2020年10月1日 · Description. Jess Scully: "Taiwan’s civic hackers were organized around a leaderless collective called g0v (pronounced “gov zero.”) Many believed in radical transparency, in throwing opaque processes open to the light, and in the idea that everyone who is affected by a decision should have a say in it.

  4. 2009年6月30日 · Because of its two defining characteristics, a common-pool resource is subject to problems of congestion, overuse and potential destruction. Access to, withdrawal from, management and ownership of such a resource can be in the form of a common property regime, but it need not be.

  5. 1. "Welcome to Blockchain Commons: Creating Open & Interoperable, Secure & Compassionate Digital Infrastructure: "Advocating for the creation of open, interoperable, secure & compassionate digital infrastructure to enable people to control their own digital destiny and to maintain their human dignity online.

  6. OneSwarm is a new peer-to-peer tool that provides users with explicit control over their privacy by letting them determine how data is shared. Instead of sharing data indiscriminately, data shared with OneSwarm can be made public, it can be shared with friends, shared with some friends but not others, and so forth.
