The BIW (BITWORLD) blockchain network is a solution for blockchain network scaling that utilizes layer 2 technology on the Ethereum and Bitcoin networks. BIW officially activated the BIW network hard fork at block BVW480000. The main purpose of the BIW hard fork network is to establish a layer 2 blockchain network within the Bitcoin and Ethereum networks, lowering the cost of BTC and ETH settlements. When users make small transactions or transfers on Bitcoin and Ethereum, they can choose to use the BIW layer 2 network for settlement. The cost is only 1% of the original cost. Meanwhile, BITWORLD has launched two professional mining machines, BITWORLD-90T and BITWORLD-120T, to provide the main computing power for the BIW network. When users use the BIW layer 2 network for BTC and ETH transactions, they need to pay BTC and ETH as mining fees for the layer 2 network. BIW miners will receive this portion of the rewards. The Pollux developer community is committed to continuously exploring the development and application of layer 2 and layer 3 in dapp applications under the premise of complete decentralization.
