Abstract

A comprehensive analysis is necessary for the implementation and use of smart contracts in companies. This overview clarifies how this technology is now being used and identifies problems that are preventing its usage in contemporary organizations. This paper offers an organized assessment of prior research that includes frameworks, techniques, functional prototypes, and simulations that show how smart contracts are used in businesses. This paper's main goal is to better understand how smart-contract technology is used in organizations today. While there is limited knowledge about how smart contracts are used in companies, there is significant progress being made in the development of the technology that supports them. In this work, we describe the characteristics of smart-contract applications in many current organization fields. We further examine and group issues that hinder the adoption of smart-contract applications.

Abstract

Sekarang ini orang tidak lepas dari internet, dari bangun pagi kebanyakan orang sudah disibukan untuk melakukan update status, browsing berita dan berkirim email. Dalam jejaring social seperti facebook atau yang lain nya kebanyakan orang menceritakan suasana yang dialaminya ke tempat jejaring sosial seperti menceritakan sedang liburan, makan, jalan-jalan pada facebook, twitter ataupun yang lainnya, sehingga dari data tersebut sekarang ini membentuk menjadi data yang sangat besar atau dikenal dengan “Big Data”. Media sosial seperti twitter banyak dipakai untuk mencurahkan isi hati pemakai nya, sehingga data tersebut dapat menggambarkan sentimen. Naïve bayes merupakan metode klasifikasi analisi sentiment yang banyak digunakan karena ketangguhan, sederhana dan akurasi yang tinggi dalam mengklasifikasi data. Pada penelitian ini menganalisis data dari twitter dengan pencarian merk mobil yang terlaris berdasarkan data dari GAIKINDO (Gabungan Industri Kendaraan Bermotor Indonesia). Dengan menggunakan tiga kelas maka dapat menghasilkan nilai akurasi sebesar 93%, dan tingkat precision positif sebesar 90%, precision negatif sebesar 90% dan sentimen yang netral 100% sehingga naïve bayes mampu menganalisis dengan akurasi yang tinggi.

Abstract

Due to the unavailability of issuing entities, the increasing number of valuable documents that are still being issued in printed form has an impact on forgery and cannot be verified.

These activities are listed as being able to identify, analyze, and try out any of the ledger options that are available. arise to provide greater efficiency, reliability, and a level of independence. By implementing a prototype that could issue, verify, and distribute certificates, the fact of the concept was proposed. The experimental test results are given, as well as the use of blockchain technology for the purpose of analyzing. Finally, this work outlines the current growth and maturity of equipment encountered, reports progress and limitations, and reveals issues that still need to be addressed.
