When I run bitcoin-qt, I noticed that it is taking lot of time to download recent blocks. It gives me impression that the more transactions, the bigger the blockchain. Even today the download is taking around a day. What happens after a year?
It may easily take more than 5 days. If it grows huge, can the current software handle it?
What is the estimation of the blockchain to grow in next 10 years? Is it possible to split the blockchain into multiple blockchains? Could it become a blocker for Bitcoin adoption?
