Too Long; Didn't Read
Blockchains are extensive, distributed, and encrypted, which can be slow and inefficient. They take longer to process as the number of users increases in the network. As the network evolves, there should be more participants and greater competition for computational power, which uses energy. New blockchain protocols like Slice Ledger can handle up to 2000 transactions per second. Despite the issues it may currently have, there will inevitably be more reasons to embrace blockchain as a solution as our lives become more digital. Developers will uncover dozens more applications for blockchain technology as the market and technology advance.
