Transactions are considered having occurred when they’re included in a brand new web page within the checklist of all Bitcoin transactions.
Every web page within the checklist is known as a “block”. The checklist itself is a transaction journal referred to as the Bitcoin “blockchain”.
Each Bitcoin pockets that works as Bitcoin’s inventor initially supposed will speak to a couple close by wallets (or different “nodes” within the Bitcoin community) to search out out about new unconfirmed transactions and new pages (blocks) within the transaction journal (blockchain). They every hold their very own copy of the entire checklist from the start of Bitcoin in 2008. This course of is known as “synchronising”.
Some wallets might discard previous blocks which are now not of curiosity. That is referred to as pruning. It is not actually related to your state of affairs but when I do not point out it, somebody might really feel the necessity to level this out.
By speaking with others on the community, a pockets might uncover that it lacks particulars of some current transactions and inform you it’s “synchronising”.
Once you ask a pockets to pay somebody. the pockets creates a transaction we name an unconfirmed transaction. This is sort of a draft transaction.
The unconfirmed transaction is just considered having actually occurred when it’s added to a brand new web page (block) of the transaction checklist (blockchain) by a miner. That is referred to as a affirmation of the transaction.
Till a pockets is synchronised, it might not find out about particulars of current transactions and so might not but know the end result of current transactions it has created.
