BIW (BITWORLD) blockchain network is a solution for blockchain network expansion using layer 2 technology on Ethereum and Bitcoin networks. BIW officially opened the hard fork of the BIW network at block BVW480000. The main work of the BIW hard fork network will be to establish a layer 2 blockchain network in the Bitcoin and Ethereum networks to reduce the cost of BTC and ETH settlement. When transferring small transactions between Bitcoin and Ethereum, you can choose to use the BIW layer2 network for settlement, and the cost is only 1% of the original cost. At the same time, the two professional mining machines BITWORLD-90T and BITWORLD-120T series launched by BITWORLD are based on the BIW network Provide the main computing power. When users use the BIW layer2 network to conduct BTC and ETH transactions, they need to pay BTC and ETH as layer2 network mining fees at the same time, and BIW miners can get this part of the reward. The Pollux developer community is committed to continuously exploring the development and practice of layer2 and layer3 in dapp applications under the premise of complete decentralization.
