Information Density — The Lens

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Info Density Power-words vs. Substance ratio.

Information density is remarkably high due to a massive, granular changelog spanning from 2020 to late 2025. Headings such as [H3] Backup Seed Words to PDF and [H3] PIN protection are functional rather than promotional. The body text prioritizes technical disclosures, such as the specific warning that outgoing ZEC transactions are no longer supported, over generic marketing fluff.

Information Density is read straight from the body copy: how much of the text carries grounded, checkable substance versus hollow filler. Below is the clean text the engine analyzed, then the industry’s known generic-claim patterns to weigh it against.

[H2] Disclaimers
There are some known areas for improvement:
This app depends upon related libraries that it uses. There may be bugs.
The wallet only supports transactions between shielded Z-addresses, rendering it incompatible with wallets that cannot send to supported shielded pools.
Similar to other cryptocurrency wallets, traffic analysis can potentially compromise user privacy.
The wallet relies on the lightwalletd server to provide accurate transaction information, necessitating trust in the server.
This app has been developed and run exclusively on mainnet and may not function correctly on testnet.
For more information regarding the security and privacy limitations of the wallet, please refer to the Wallet App Threat Model.
