➡️LEVEL 10 - BLOCKCHAIN INTERFACES & UTILITIES
_ platforms aggregate and interpret vast amounts of on-chain data to produce useful metrics and insights about network health, economic activity, market sentiment, and more.
B. On-chain Analytics
Which statement best describes the differences among lightweight wallets, full-node wallets, and third-party wallet applications in the context of blockchain?
C. Lightweight wallets don't store the entire blockchain but allow transactions, full-node wallets store and verify the entire blockchain, and third-party wallets are applications developed by external entities to manage keys and transact.
_ are blockchain systems that run parallel to a “mainchain" or L1 blockchain providing a mechanism to offload transactions from the mainchain, while performing their own consensus mechanism to reduce congestion and allow for faster processing times and interoperability.
D. Sidechains
