DAPP合約挖礦/質(zhì)押挖礦/流動性挖礦/算力分紅項目系統(tǒng)開發(fā)成熟技術(shù)/案例項目/方案源碼
區(qū)塊鏈作為一種新型的技術(shù)組合，綜合了P2P網(wǎng)絡(luò)、共識算法、非對稱加密、智能合約等新型技術(shù)，是一種在對等網(wǎng)絡(luò)（也稱分布式網(wǎng)絡(luò)、點對點網(wǎng)絡(luò)）環(huán)境下，通過透明和可信的規(guī)則，構(gòu)建可追溯的塊鏈式數(shù)據(jù)結(jié)構(gòu)，具有分布式對等、鏈式數(shù)據(jù)塊、防偽造和防篡改、可追溯、透明可信和高可靠性的典型特征
數(shù)據(jù)作為新型生產(chǎn)要素，能為實體經(jīng)濟帶來放大、疊加和倍增作用，是做強做優(yōu)做大數(shù)字經(jīng)濟的關(guān)鍵。
Establishing a reliable data circulation system to enhance the availability,credibility,circulation,and traceability of data is an important way to activate the potential of data elements and empower the real economy.區(qū)塊鏈技術(shù)具有去中心化、共識機制、不可篡改、可以追溯、規(guī)則透明等特點。
