區塊鏈應用（僅部分）：
1. 蘭嶼達悟族數位身份，通過以太坊區（Ethereum）塊鏈，只要「蘭恩基金會或是臺灣說蘭嶼環境教育協會等原住民自治組織」認證，就獲得自己的數位身份。
其他報導：區塊鏈的應用 - 數位身份證（專利與產品）（http://enpan.blogspot.com/2017/09/blog-post_18.html）。
專利參考：微軟US9477832
1. A stand-alone computer outside of a domain defined by a plurality of clients, the stand-alone computer comprising:
at least one processing device;
memory coupled to the at least one processor; and
an application program stored in the memory that, based on execution by the at least one processing device, configures the at least one processing device to:
access a Digital Identity Management System (DIMS), the DIMS including an abstraction layer configured to abstract a digital ID associated with the application program as an abstracted digital ID;
search for credentials based on one or more attributes;
return results of the credential search to the DIMS, the DIMS being configured to open the credentials based on a cryptographic key and to return an object reference to the application program; and
use the object reference to perform an operation on the stand-alone computer.
2. 蘭嶼觀光護照，也是數位身份的一種，在以太坊區塊鏈上，被永久保存且不能被竄改與偽造。

1. A computer-implemented method comprising acts of:
generating a badge for use in attesting to an identity of an identity owner, wherein the act of generating comprises:
identifying a plurality of values, each value corresponding to an attribute of a plurality of attributes;
generating an attribute attestation for each attribute of the plurality of attributes, the attribute attestation comprising at least one cryptographic proof of the value corresponding to the attribute of the plurality of attributes; and
identifying an entity as being responsible for verifying the badge;
publishing the badge to a distributed ledger system, wherein:
the badge includes the attribute attestation for each attribute of the plurality of attributes;
the distributed ledger system comprises a digital identity representation associated with the identity owner;
the digital identity representation comprises program code that implements rules for attestation; and
for at least one attribute of the plurality of attributes, the program code, when executed, allows access to a cryptographic proof in the attribute attestation for the at least one attribute only when the attribute attestation is in a VERIFIED state; and
sending, via the distributed ledger system, a request to the responsible entity to verify the badge; and
sending, via a channel outside the distributed ledger system, to the responsible entity, the plurality of values corresponding respectively to the plurality of attributes.
3. 虛擬貨幣，DTCO（Digital Treasury Corporation）發表達悟幣（TAO Coins），預計初期發售價格是1ETH=1000TAO（以太幣以1:1000的比例來綁定達悟幣），不僅可以成為蘭嶼的流通貨幣，也可以讓觀光客擁有與使用。
4. 供應鏈追溯，從DTCO網站上可以略虧一二，這與過去曾經提到的「數位金庫」有關，可以通過區塊鏈追溯鑽石、黃金這些貴重物品的來源，避免不明來源。
5. 智慧財產權交易，DTCO的網站上提出「P2P智慧財產公證交易平台」，光看這名稱，這是個很棒的交易方式，因為官方不容易要求每筆智慧財產的交易都要在官方網頁上登錄（否則不能主張權利），但通過區塊鏈，就更便民，更公正（不得竄改）。

my two cents:
用在蘭嶼的區塊鏈應用是個小規模的實驗，成不成，不曉得，但是卻是十分有未來性，不會沒有意義。從區塊鏈學到一件事，就是「認同」，包括身份認同、護照、虛擬貨幣（代幣），不用政府承認，兩個人以上認同，這事就成了。
其他應用還有：錢包、文創授權（版權交易）、電交易、碳交易、證物管理、飛行里程、保險、訂房、貨品運輸管理、跨境轉帳、打擊盜版、捐款（款項應用追蹤）、合約、防洗錢...。
