Transakcij

Transakcij is a term used in several languages to denote a transaction — the act of exchanging goods, services, or value between two or more parties. In many contexts, transakcij refers to the recording of such exchanges in ledgers or records and may describe a transfer of ownership, funds, or rights.

In finance and commerce, a transaction is any event that changes the financial position of an individual or organization, such as a payment, purchase, sale, or investment. Transactions generate evidence in the form of receipts, confirmations, and ledger entries, and may be settled or cleared through banks, payment networks, or intermediaries. Transaction costs cover fees, spreads, and time spent processing the exchange.

In information technology and databases, a transaction is a unit of work that must be completed completely or not at all to preserve data integrity. The classical ACID properties define Atomicity, Consistency, Isolation, and Durability. In distributed systems, coordination may rely on mechanisms such as two-phase commit or compensating transactions to ensure reliability across multiple components.

In blockchain and digital currencies, a transaction records a transfer of value or state between addresses on a distributed ledger. Each transaction is cryptographically signed and added to a public history; nodes validate transactions and reach consensus to confirm them, after which they are typically considered final and irreversible on most networks.

Legal and regulatory aspects of transactions include contract and commercial law, documentation, auditing, taxation, and compliance with anti-money laundering rules and consumer protections. Clear records support dispute resolution, financial reporting, and regulatory oversight.
