<prompt> Fana ka tlhaloso ea blockchain.nan  <response>: Instruction in English: Provide a definition of a blockchain. . Response in English: A blockchain is a decentralized, distributed ledger that records transactions on multiple computers in a way that makes it virtually impossible to alter, hack or cheat the system. It is a growing list of records, called blocks, that are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Blockchains are used to securely store and transfer data, and are commonly used in cryptocurrencies like Bitcoin. They offer a high level of transparency, security and immutability, since all participants have access to a real-time record of transactions and once a block is added to the chain, it cannot be altered. . Response in Sesotho: Blockchain ke ledja e arolelanoang, e ajoang e tlalehang litšebelisano ho likhomphutha tse ngata ka tsela e etsang hore ho se khonehe ho fetola, ho qhekella kapa ho qhekella sistimi. Ke lenane le ntseng le hola la lirekoto, tse bitsoang li-blocks, tse hokahantsoeng ka mokhoa oa ho ngola mongolo. Sebaka se seng le se seng se na le cryptographic hash ea block e fetileng, setempe sa nako, le data ea transaction. Li-blockchains li sebelisetsoa ho boloka le ho fetisa data ka mokhoa o sireletsehileng, me hangata li sebelisoa ho li-cryptocurrencies tse kang Bitcoin. Ba fana ka boemo bo phahameng ba ponaletso, tsireletso le ho se fetohe, kaha barupeluoa bohle ba na le monyetla oa ho fumana tlaleho ea nako ea sebele ea litšebelisano me hang ha thibela e kenngoa ketane, e ke ke ea fetoloa.
