Cogent SOL ($CGNTSOL) is a tokenized representation on Solana of a stake account delegated to the Cogent Crypto validator. It uses the audited spl stakepool program to implement this representation. After each epoch, cgntSOL’s underlying stake accounts increase in value and subsequently the amount of SOL each cgntSOL represents increases.
With tokenized stake accounts, e.g. cgntSOL, you can use almost any Solana program while holding onto an asset that is increasing value relative to SOL. That alone can be quite compelling but net new use cases utilizing the composability of tokens will bring even more compelling possibilities in the future.
