Abstract: Aiming at the characteristics and pain points of the Internet of Things, it is proposed to take the blockchain technology as the core, combine the Internet of Things technology and use the RISC-V architecture to realize the sinking of the blockchain function to the terminal. The function of carrying the blockchain through the chip makes each terminal become a node of the blockchain, and the distributed characteristics of the blockchain are used to meet the terminal node functions of the Internet of Things. The chip is used to solve the credibility of the data on the chain from the source, and the existing blockchain functions are light-weighted to make it conform to the hardware characteristics of the chip. Through RISC-V′s modular, high-performance, and customizable instruction set, the chip carries the blockchain function. After reasonable analysis and examples, the terminal can be used as a blockchain node to solve the diversified application scenarios of the Internet of Things, which can improve performance and reduce costs while satisfying security and credibility.
Key words : blockchain,;RISC-V,;Internet of Things;function sinking

    根據(jù)統(tǒng)計(jì)和預(yù)測(cè),,2020年全年中國(guó)物聯(lián)網(wǎng)連接數(shù)量達(dá)到40億,,到2025年將增長(zhǎng)至80.1億次,5年增長(zhǎng)2倍左右,。全球物聯(lián)網(wǎng)市場(chǎng)支出將從2020年7 420億美元增長(zhǎng)至2024年的1.138萬(wàn)億美元,,復(fù)合年均增長(zhǎng)率為11.3%[1]。大量的連接數(shù)意味著數(shù)據(jù)價(jià)值作用凸顯,,我國(guó)推動(dòng)數(shù)字經(jīng)濟(jì)發(fā)展的一個(gè)關(guān)鍵方式是合理利用價(jià)值化數(shù)據(jù),,加快推進(jìn)數(shù)據(jù)價(jià)值化進(jìn)程是發(fā)展數(shù)字經(jīng)濟(jì)的本質(zhì)要求[2]。但數(shù)據(jù)要素的價(jià)值實(shí)現(xiàn)依賴于對(duì)數(shù)據(jù)資源的深度整合開(kāi)發(fā)和利用,,而“數(shù)據(jù)孤島”妨礙了數(shù)據(jù)的整合,、共享與互通。

    為了解決“數(shù)據(jù)孤島”的問(wèn)題,,推動(dòng)數(shù)據(jù)的整合共享與利用,,推進(jìn)數(shù)字經(jīng)濟(jì)發(fā)展,國(guó)內(nèi)諸多專家進(jìn)行了多方的研究與探索[3-7],。然而,,研究方向集中在大數(shù)據(jù)應(yīng)用、數(shù)據(jù)挖掘,、數(shù)據(jù)可視化等顯性方面,,而從數(shù)據(jù)源頭出發(fā)進(jìn)行物與物的數(shù)據(jù)共享互聯(lián)有助于實(shí)現(xiàn)真正的物聯(lián)網(wǎng)終端應(yīng)用場(chǎng)景。

    物聯(lián)網(wǎng)的蓬勃發(fā)展帶來(lái)了終端的多樣性,,這也造成物聯(lián)網(wǎng)應(yīng)用的碎片化,,碎片化的應(yīng)用恰恰與區(qū)塊鏈的去中心化思想一致,利用區(qū)塊鏈能夠滿足物聯(lián)網(wǎng)碎片化應(yīng)用的需求,。終端與數(shù)據(jù)作為物聯(lián)網(wǎng)的兩大基石,,通過(guò)數(shù)據(jù)與數(shù)據(jù)的交換能夠產(chǎn)生數(shù)據(jù)的價(jià)值,終端與數(shù)據(jù)的安全,、可靠,、可信是靠芯片發(fā)揮關(guān)鍵的作用。芯片與區(qū)塊鏈的結(jié)合,,能夠從數(shù)據(jù)源頭構(gòu)建更安全可信的物聯(lián)網(wǎng),。芯片自主安全的目標(biāo)需要開(kāi)源的RISC-V內(nèi)核,其在性能,、DSP指令,、緩存配置、算法執(zhí)行性能上能夠滿足區(qū)塊鏈應(yīng)用的要求,,進(jìn)而通過(guò)區(qū)塊鏈與RISC-V實(shí)現(xiàn)數(shù)據(jù)價(jià)值的作用,,推動(dòng)數(shù)字經(jīng)濟(jì)的發(fā)展。
