 # Background
 The emergence of EOS has brought new imagination to the blockchain. In just a few months since the main network was launched, the version has undergone dozens of upgrades, not only the stability has been greatly improved, but also the new functions have been gradually realized. The node team is also actively involved in building the EOSIO ecosystem. What is even more exciting is that EOS has attracted more and more development teams. There are already hundreds of DApp running on the EOS main network. The transaction volume and circulation market value far exceed Ethereum, and the space for development is growing broader.

 1. Build from code : `bash ./eosio_build.sh -s BOS`

-1. Only allow Feature Branch or bug fix to submit PR to Develop Branch.

 EOS的出现给区块链带来了新的想象力，主网启动短短几个月以来，版本经历了几十次升级，不仅稳定性得到了很大提高，并且新功能也逐步实现，各个节点团队也积极参与建设EOSIO生态。让人更加兴奋的是，EOS已经吸引了越来越多的开发团队，当前已经有数百个DApp在EOS主网上面运行，其交易量和流通市值远超以太坊，可发展的空间愈来愈广阔。
