What is blockchain technology?
It’s a shared ledger for recording the history of transactions – that cannot be altered.
Why we need it?
Transactions take place every second — orders, payments, account tracking. Often, each participant has his own ledger — and, thus, his own version of the truth. Having multiple ledgers is a recipe for error, fraud and inefficiencies. The goal is to see a transaction end-to-end and reduce those vulnerabilities.
