On December 7, Atomicals proposed an innovative split scheme for ARC-20 tokens in the official document, aiming to solve the dust limit problem in the BTC network. In the BTC network, the minimum unit of a single UTXO transmission is 546 satosher shares, which limits the use of ARC-20 tokens in microtransactions. Atomicals' proposed scheme overcomes this limitation by introducing a Substantiation Factor (SF) that redefines the number of satoshis required to support a single ARC-20 token. The core of the scheme is to allow token holders to convert their token units from 1:1 to smaller ratios such as 1:10, 1:100, etc., effectively splitting or subdividing their token units to arbitrary precision. It's worth noting that doing so requires a regular satoshi to be collateralized as a token unit accordingly. By default, the operation of ARC-20 is 0 decimal places, which is the materialization of 1:1. By varying the exponent to obtain decimal places, different proportions can be rescaled or re-substantiated. For example, to trade 1 token unit while respecting the dust limit, simply materialize each token unit with 1,000 satoshis and then execute a transfer of 1,000 satoshi with an index of 3. This solution not only maintains the fungibility and liquidity of ARC-20 tokens, but also greatly improves the flexibility and precision of transactions.
