I am currently working on a program within the Near Protocol to generate user-specific Near token ownership statistics. However, I'm not sure how to obtain a list of all user accounts. Is there an indexer or any other method to obtain this?
NEAR recently launched a BigQuery Public Dataset and you could use this query to get a list of active accounts:
select account_id
from `bigquery-public-data.crypto_near_mainnet_us.accounts`
where is_active = true;
Here is the documentation that explains how to use the dataset https://docs.near.org/bos/queryapi/big-query
