<prompt> Hlalosa tsebetso ea ledger ea blockchain.nan  <response>: Instruction in English: Explain the working of a blockchain ledger. . Response in English: A blockchain ledger is a digital record of transactions that is maintained in a decentralized manner across a network of computers. It is secured through the use of cryptography, where each block in the chain contains a number of transactions and a reference to the previous block.At its most basic level, a blockchain ledger works by recording a series of transactions in bundles, which are also termed as blocks. Each block contains several transactions, the details of which are verified by participants in the network, typically through a consensus mechanism. This ensures that the transactions are valid and in line with the rules of the blockchain. Once a block has been verified, it is added to the record of previous transactions, creating a chain of blocks or a blockchain.Each block contains a cryptographic hash of the previous block, along with the transaction data, which ensures that any changes to the transaction data will result in a change in the hash of the block, making it clear that the data has been tampered with. In addition, blockchain networks often use a consensus mechanism to ensure that only valid blocks are added to the ledger. These mechanisms can vary, but one common approach is proof-of-work, where participants in the network compete to solve complex mathematical problems, verifying transactions and adding new blocks to the chain. Once a block is added, it is considered to be a permanent part of the ledger, making it difficult, if not impossible, to change.By maintaining a decentralized record of transactional data, a blockchain ledger provides a secure, transparent, and tamper-resistant way to track and verify the transfer of assets, whether that is cryptocurrency or other forms of valued information. It eliminates the need for intermediaries, enabling direct peer-to-peer transactions and increasing the efficiency of the entire process. . Response in Sesotho: Ledger ea blockchain ke rekoto ea dijithale ea litšebelisano tse bolokiloeng ka mokhoa o ikhethileng marang-rang a likhomphutha. E sirelelitsoe ka tšebeliso ea li-cryptography, moo sebaka se seng le se seng sa ketane se nang le palo ea litšebelisano le ho bua ka thibela e fetileng. Boemong ba eona ba mantlha, ledger ea blockchain e sebetsa ka ho rekota letoto la litšebelisano ka mekotla, tseo hape li bitsoang li-blocks. Sebaka se seng le se seng se na le litšebelisano tse maloa, tseo lintlha tsa tsona li netefalitsoeng ke barupeluoa marang-rang, hangata ka mokhoa oa ho lumellana. Sena se tiisa hore litšebelisano li nepahetse ebile li lumellana le melao ea blockchain. Hang ha thibela e netefalitsoe, e kenngoa tlalehong ea litšebelisano tse fetileng, ho theha ketane ea li-blocks kapa blockchain. Sebaka se seng le se seng se na le li-cryptographic hash tsa block e fetileng, hammoho le data ea transaction, e tiisang hore liphetoho leha e le life ho data ea transaction li tla etsa hore ho be le phetoho ea hash ea block, ho hlakisa hore data e senyehile. Ho phaella moo, marang-rang a blockchain a atisa ho sebelisa mokhoa oa ho lumellana ho etsa bonnete ba hore li-blocks tse nepahetseng feela li kenngoa ho ledger. Mekhoa ena e ka fapana, empa mokhoa o le mong o tloaelehileng ke bopaki ba mosebetsi, moo barupeluoa ba marang-rang ba hlōlisanang ho rarolla mathata a rarahaneng a lipalo, ho netefatsa litšebelisano le ho eketsa li-blocks tse ncha ho ketane. Hang ha block e kenyelelitsoe, e nkoa e le karolo ea ka ho sa feleng ea ledger, e leng ho etsang hore ho be thata, kapa ho ke ke ha khoneha, ho fetoha. Ka ho boloka rekoto e pharalletseng ea data ea transaction, blockchain ledger e fana ka mokhoa o bolokehileng, o pepeneneng, le o hananang oa ho latela le ho netefatsa phetiso ea thepa, ebang ke chelete ea crypto kapa mefuta e meng ea tlhaiso-leseling ea bohlokoa. E felisa tlhokahalo ea bakena-lipakeng, e nolofalletsang litšebelisano tse tobileng tsa lithaka le ho eketsa katleho ea tsebetso eohle.
