 # Gaze Indexer

-Gaze Indexer is an open-source and modular indexing client for Bitcoin meta-protocols with **Unified Consistent APIs** across fungible token protocols.
+Gaze Indexer is an open-source and modular indexing client for Bitcoin meta-protocols. It has support for Runes out of the box, with **Unified Consistent APIs** across fungible token protocols.

 Gaze Indexer is built with **modularity** in mind, allowing users to run all modules in one monolithic instance with a single command, or as a distributed cluster of micro-services.

-# Compare this benchmark to go-ethereum/common.Address utils
- go-ethereum/common.HexToAddress speed: 45 ns/op, 48 B/op, 1 allocs/op
- go-ethereum/common.IsHexAddress speed: 25 ns/op, 0 B/op, 0 allocs/op
-
-It's slower than go-ethereum/common.Address utils because ethereum wallet address is Hex string 20 bytes,
-but Bitcoin has many types of address and each type has complex algorithm to solve (can't solve and validate address type directly from address string)

-	Idea for solving this:
-		- When trying to find the best UTXOs to use, we:
-			- Will not reject when user's balance is not enough, instead we will return all UTXOs even if it's not enough.
-			- Will be okay returning excessive UTXOs (say we predict we need 10K satoshis, but actually we only need 5K satoshis, then we will return UTXOs enough for 10K satoshis)
-		- And then we:
-			- Construct the actual PSBT, then select UTXOs to use accordingly,
-			- If the user's balance is not enough, then we will return an error,
-			- Or if when we predict we expect to use more UTXOs than the actual transaction, then we will just use what's needed.
