$LAYER The term "layer token" can have different meanings depending on the context (e.g., blockchain, machine learning, networking). Here are the most common definitions:

1. In Blockchain / Web3:

A Layer token often refers to a cryptocurrency or token associated with a blockchain layer:

Layer 1 Token: A token that operates on the base blockchain (e.g., ETH for Ethereum, BTC for Bitcoin).

Layer 2 Token: A token on a protocol built on top of Layer 1, meant to scale or enhance the base layer (e.g., MATIC for Polygon, which is a Layer 2 of Ethereum).

2. In Natural Language Processing (NLP):

A layer token may refer to:

A token (word or subword) being processed through multiple layers of a transformer model (e.g., BERT, GPT).

Each layer transforms the token representation to capture more abstract features.

3. In Networking:

It might refer to a security token or authentication token used at a certain layer of the OSI model (e.g., token used in the application layer).
