137個國家，佔全球GDP 98%，在2025年積極探索區塊鏈技術，標誌著由試點轉向實際生產部署，涵蓋數碼支付、身份認證、選舉及公共記錄。
這種前所未有的推動力反映各國政府日益認同區塊鏈能提升透明度、降低成本、改善市民服務。轉變尤見於央行數碼貨幣（CBDC），全球有49個活躍的試點，展示對數碼貨幣體系的認真承諾，而土地登記和數碼身份系統的落地實例，證明區塊鏈在政府營運具實際價值。
地緣政治影響同樣重大，圍繞貨幣主權與跨境支付體系出現競爭願景。中國數碼人民幣累積交易額達9,860億美元，相反美國則於總統令明確禁止零售CBDC發展。歐盟的數碼身份錢包則是跨27國推動公民自主管理數碼憑證最具雄心的嘗試。
本篇分析剖析政府區塊鏈應用現況，揭示進展與挑戰。從愛沙尼亞的區塊鏈護理記錄覆蓋99%市民，到新加坡作為聯合國數碼公共財的開源憑證框架，各地政 府正實施具體成效的區塊鏈方案，同時面對科技、法規和政治的複雜考量。
央行數碼貨幣重塑全球支付
2025年全球CBDC出現重大突破，政策及科技革新重塑國際貨幣體系。據Atlantic Council官方CBDC追蹤數據，現時有137個國家及貨幣聯盟積極探索數碼貨幣，較2020年5月的35國急劇上升。當中包括72個已進入先進研發階段、49個現行試點及三個正式推出的零售CBDC。
中國數碼人民幣(e-CNY)持續展現全球領導地位，是全球規模最大的CBDC試點，覆蓋25個城市。2024年6月，交易量達7萬億數碼人民幣（約9860億美元），較前一年1.8萬億大幅增長。該系統在17個省區支援2.61億個數碼錢包，應用至教育、醫療和旅遊。IATA確認2025年底將e-CNY納入全球航空結算系統，跨境推動mBridge項目與泰國、阿聯酋、香港及沙特連結商業批發支付。
印度的數碼盧比試點為全球第二大CBDC，流通額由2024年的23.4億盧比（2,800萬美元）激增至2025年3月的101.6億盧比（1.22億美元），增長334%。印度儲備銀行已將零售及批發CBDC擴展至15城，涉及17間銀行參與零售試點、16間銀行參與批發。新發展包括離線支付、可編程功能、向農民直接分發碳信用及與統一借貸界面接軌，拓展金融服務。
歐洲央行的數碼歐元項目2025年進入關鍵決策階段，理事會預定於同年10月決定項目走向。2023年11月至2025年10月的準備期涵蓋用戶研究及技術開發。值得一提的是，ECB選用XRP Ledger作12個月的數碼歐元試點（2025年6月起），並有七大工作小組聚焦用戶體驗、風險管理及實施策略。創新平台邀請約70家市場公司參與條件付款技術試驗，為2026年正式發佈及歐盟立法修訂提供重要建議。
美國則採用根本不同策略，徹底逆轉CBDC政策。 特朗普總統於2025年1月簽署行政命令，禁止一切零售CBDC研發，參議院隨即提出「No CBDC Act」立法永久禁止，眾議院於2025年7月通過反CBDC監控法案，成為唯一明確叫停零售CBDC的大型經濟體。然而，紐約聯儲繼續以聯儲系統參與Project Agorá，專研跨境批發支付。官員強調參與僅限於研究和測試。
國際區塊鏈支付網絡勢頭漸起
2025年跨境區塊鏈支付計劃快速發展，mBridge項目從實驗轉為正式營運。BIS於2024年10月將管理權移交予參與央行，邁向獨立運作。現時有五名正式參與者：中國、香港、泰國、阿聯酋和沙特（2024年加入），另有31個觀察機構，包括多間央行、IMF及世界銀行。
mBridge已達最小可行產品階段，試點期間完成160+筆總值1.71億港元的支付與外匯交易，平台累計發行2,200萬美元，20家商業銀行參與。中銀香港成為首家全面接通mBridge的本地銀行，為企業客戶提供支付。平台自設區塊鏈兼容Ethereum虛擬機，支援批發CBDC智能合約的即時P2P跨境支付。
Project Agorá作為BIS創新樞紐最大項目，由七間主要央行和40多家私營機構（如JPMorgan、德銀、瑞銀、Visa及Mastercard）參與。設計階段於2024年9月展開，年內預計發佈報告，重點研究如何將批發央行資金及商業存款以代幣形式於統一賬本上運行，並示範與批發CBDC整合，或打破現行國際支付架構。
其他跨境項目亦持續發展實際應用。例如Project Dunbar於2022年3月完成多CBDC原型，涵蓋澳洲、馬來西亞、新加坡、南非，利用Corda及Partior平台。Project Icebreaker於2023年3月成功示範以不同DLT平台進行零售CBDC跨境支付，以自動選擇最便宜匯率供用戶。
這些發展的地緣政治重要性不容忽視。金磚國家正以CBDC及區塊鏈支付減少對美元依賴，現亞洲及中東38%國際貿易經人民幣系統結算。13個批發CBDC項目致力建立替代SWIFT的體系，區域聯盟擴充如mBridge亦開闢新支付通道，有潛力重塑全球金融架構。
數碼身份系統大規模落地

Challenges and regulatory considerations
Government blockchain implementations face significant technical, regulatory, and operational challenges requiring careful navigation. Privacy and data protection present complex issues with GDPR compliance, as blockchain's immutability conflicts with GDPR Articles 16 and 17 requiring data modification and deletion rights. Decentralized systems complicate identification of responsible data controllers, while cross-border blockchain networks create jurisdictional challenges for international implementations.
政府區塊鏈在技術、監管及營運上均面臨重大挑戰，需審慎處理。私隱及數據保障尤其複雜，因區塊鏈數據不可更改性，與 GDPR 第16及17條賦予的數據修改與刪除權有所衝突。去中心化網絡令負責數據管理者身份難界定，跨境區塊鏈則造成司法管轄權爭議，令國際落地更具挑戰。
Technical solutions emerging include Zero-Knowledge Proofs (zk-SNARKs) for privacy-preserving verification, Privacy Pools protocols enabling compliance demonstration without revealing transaction history, and cryptographic methods for data obscuring rather than deletion. NIST leadership on standards development published comprehensive guidelines including NISTIR 8202 "Blockchain Technology Overview,"
技術應對方案包括零知識證明（zk-SNARKs）用於保護私隱驗證、Privacy Pools 協議展示合規但無須公開交易歷史、及以密碼學將資料模糊而非刪除。NIST 主導標準制定，並發布沿蓋全面指引，例如 NISTIR 8202《區塊鏈技術總覽》，NISTIR 8301關於代幣設計及管理、區塊鏈身份管理系統的網絡安全白皮書，以及IR 8403有關區塊鏈存取控制系統。
互通性與標準挑戰需要協調解決方案。 主要問題包括由封閉技術平台創建的「圍牆花園」，阻礙跨鏈通信，標準在多種競爭協議和資料格式之間分裂，以及將區塊鏈網絡連接現有政府IT基礎設施時的舊系統整合困難。國土安全部強調應聚焦於以開放標準及可互通的基線安全為基礎的解決辦法，確保各項實施可兼容協作。
可擴展性和效能障礙包括多數區塊鏈網絡每秒處理的交易量比傳統資料庫少、工作量證明機制對計算資源需求高致使耗能大，以及整條區塊鏈在節點間的完整複製導致儲存成本上升，增加了可擴展性挑戰。政府面臨的特殊挑戰包括美國海關與邊境保護局（CBP）因區塊鏈入口追蹤系統的擴展限制及與既有高流量政府系統整合的複雜性，而放棄有關計劃。
聯邦層面的規管缺口包括證監會（SEC）、商品期貨交易委員會（CFTC）及銀行監管機構間的職權界線不明、跨國區塊鏈網絡橫跨多地區時的協調難度，以及有關智能合約在法庭的執行力和區塊鏈證據法律效力的疑問。州層面的差異造成監管套利，企業遷往對區塊鏈友善的州份，不同解讀的資金傳輸法例導致執法不一致，以及多州區塊鏈應用在州際商業層面的複雜性。
未來展望及策略意義
預計到2027年，政府採用區塊鏈的速度將大幅提升，數個主要趨勢將會影響發展路向。政府效能部門正在探索全面性的區塊鏈應用，以提升聯邦開支透明度及壓減成本。多個平台，包括Cardano、Hyperledger及Hedera等，正參與以區塊鏈為基礎的電子投票系統開發。財政部計劃將資助支付代幣化擴展至概念驗證階段以外。
全球央行數碼貨幣發展持續，截至2024年有49個試點項目，11個國家已完全推出數字貨幣，而中國數字人民幣以9,860億美元的交易額展示了強大可擴展性。印度的電子盧比流通量增長334%，預計至2025年3月達1.22億美元，顯示採納力度強勁。數字身份系統與人工智能結合提升身份驗證能力，自主身份解決方案亦令市民能控制個人數據。
新興應用場景反映政府區塊鏈應用逐步擴展。 如杜拜的智慧城市計劃，以全面區塊鏈政府為目標，尋求全數字化，並與大型科技企業合作。供應鏈透明度應用加強了政府採購、防衛合同及公用資源分配的追蹤能力。自動化合規系統運用智能合約實現監管合規自動化，降低政府部門的行政負擔。
技術進步推動更廣泛採納，包括零知識證明在保障敏感政府數據私隱下同時維持可審核性、互通性解決方案提供跨鏈協議使不同政府部門可於不同區塊鏈平台協作，以及抵抗量子計算的加密技術，為政府區塊鏈基建預備後量子時代的安全威脅。
AI整合涵蓋自動數據分析，AI算法可分析區塊鏈數據以檢測詐騙、提升效率，預測性分析讓政府部門更準確決策及資源分配，以及通過AI驅動威脅檢測加強區塊鏈基建的安全保障。
市場預測顯示，2025年全球政府區塊鏈開支將由20億美元增至2032年的70億美元。零售及消費品將於2024年領先區塊鏈開支增長，政府行業則在銀行、電信及製造業之後穩步採納。區塊鏈即服務（BaaS）市場將由2024年的32.5億美元擴展至2033年的1,991.5億美元，年複合增長率達58%，反映企業及政府積極採納。
成功推動政府區塊鏈的策略建議包括：分階段推展，先以低風險高影響的應用作為起點，繼而擴展至關鍵系統；聚焦互通性，優先解決跨部門協作與數據共享；私隱為先，設計時即納入零知識證明等私隱保護技術；規管配套，於大規模部署前擬訂完整法律框架；人才發展，加強政府人員區塊鏈素養及技術培訓；並以公開透明的溝通機制促成市民信任和採納。
區塊鏈技術帶來的政府運作變革，是公共部門現代化最重要的轉變之一，2025年將見證由試驗性方案邁向多種應用的正式部署。成功的關鍵在於解決互通性問題、實現規範明確、兼顧安全及私隱要求下擴展應用。研究指出，政府區塊鏈系統正由試驗階段進入營運階段，未來數年有望大幅提升公共部門效率、透明度及服務質素。
2025年政府區塊鏈應用證明這項技術已超越投機應用，轉向為市民、企業及政府部門帶來實質效益的實用方案。結合政治領導、技術成熟度及明確價值定位，區塊鏈正成為電子政府轉型的基石，預示其影響遠超個別應用，有潛力徹底重塑全球政府運作及市民獲取公共服務的方式。
