What is the end result of the difficulty in scaling the Bitcoin and Ethereum Networks? It is expensive to transfer coins on the networks. The networks slow down and the time between blocks increases. The networks must move away from proof-of-stake. The networks are becoming more centralized. QUESTION 9 What does the Lightning Network do? It acts as a substitute for other blockchains like Cardano and Avalanche. It enhances security for the Bitcoin Blockchain. It reduces the load required to mine bitcoins. It speeds up the transfer of bitcoins. QUESTION 10 The layer 2 scaling solution known as a rollup helps blockchain platform scaling by Sharding the blockchain into smaller pieces.
