  A   blockchain game   is a  video game   that includes elements that use cryptography-based  blockchain   technologies. Blockchain elements in these games are most often based on the use of  cryptocurrency   or  non-fungible tokens   (NFTs) which players can buy, sell, or trade with other players. While blockchain games have been available since 2017, blockchain games have only gathered the attention of the video game  industry  in 2021, with several  AAA publishers   have expressed strong intent to explore their potential, as well as criticism from players, developers, and companies within the game industry. Blockchain technology, such as cryptocurrencies and NFTs, are seen as additional monetization routes for video games. Many live-services game offer in-game customization options, such as character skins or other in-game items, which the players can earn and trade with other players using in-game currency. Some games also allow for trading of virtual items using real-world curren

  Teleportation   is the hypothetical transfer of  matter   or  energy   from one point to another without traversing the physical space between them. It is a common subject in science fiction  litrature   and in other popular culture. Teleportation is often paired with  time travel , being that the travelling between the two points takes an unknown period of time, sometimes being immediate. There is no known physical mechanism that would allow for teleportation. Frequently appearing scientific paper and media articles with the term  teleportation  typically report on so-called "quantum teleportation", a scheme for information transfer which, due to the no-communication theorem, still would not allow faster-than-light communication. The use of the term  teleport  to describe the hypothetical  of material objects between one place and another without physically traversing the distance between them has been documented as early as 1878. American writer is credited with having co

  A   blockchain   is a growing list of  records,  called   blocks , that are linked together using  cryptography   Each block contains a  cryptography hash   of the previous block, a  timestamp , and transaction data (generally represented as a  Markel tree ). The timestamp proves that the transaction data existed when the block was published in order to get into its hash. As blocks each contain information about the block previous to it, they form a chain, with each additional block reinforcing the ones before it. Therefore, blockchains are resistant to modification of their data because once recorded, the data in any given block cannot be altered retroactively without altering all subsequent blocks. Blockchains are typically managed by a peer-to-peer network for use as a publicly distributed ledger, where nodes collectively adhere to a protocol to communicate and validate new blocks. Although blockchain records are not unalterable as forks are possible, blockchains may be considered
