"The largest barrier right now for Blockchain in Indonesia is scalability," explained Imron Zuhri, the chief technology officer of HARA Token , a startup trying to get the country's rice growers on Blockchain, at a recent Blockchain conference held in Jakarta, Indonesia. "It provides the alternative infrastructure for a frictionless society, but the first thing we have to do is to socialize it."

Can the Blockchain turn around Indonesia's ailing agricultural sector? One tech startup thinks so—as long as it can get tens of millions of farmers living in rural communities with little-to-no broadband connection to adapt a technology few of them ever heard of before. Easy, right?

There's a reason why so many startups are obsessed with tech like Blockchain. The digital ledger system first reached a level of mass consciousness with the rise of cryptocurrencies like Bitcoin. Blockchain was the totally transparent ledger that made a decentralized currency possible. It's basically a never-ending list of all transactions, ownership, and related data constantly updated by a network of individual computers and servers all over the world. It's a "block" of data in a long, unbroken "chain." And it's applicable to way more than just cryptocurrency.

Watch: What Is Blockchain?

Just recently Blockchain has been used to coordinate the distribution of electricity to energy-poor regions of Thailand, reduce instances of voter fraud in Sierra Leone, and run the entire government in Estonia. Here in Indonesia, there's discussions to roll out a Blockchain system that allows all 92 million Nahdlatul Ulama (NU) members in Sumatra to vote—with the hope that it could be a test study to support expanding the system to the national elections.
