This article delves into the exSat project, an innovative solution supported by the EOS Foundation, designed to break Bitcoin’s scalability limitations through decentralized data indexing and trustless cross-chain functionality. exSat combines Proof of Work (PoW) and Proof of Stake (PoS) into a hybrid consensus mechanism to ensure secure synchronization of Bitcoin data. Fully compatible with the Ethereum Virtual Machine (EVM), it supports smart contract capabilities. The article provides a detailed overview of exSat's architecture, participation model, and tokenomics, revealing how this project is bringing revolutionary changes to the Bitcoin ecosystem while offering new opportunities for investors and developers.
