****Blockchain Technology, Vulnerable, Full of Potential.****
In the midst of emerging resistance in the country, technology has proven to be successful in attracting the attention of the public, so that it is still able to develop with all its limitations in certain aspects.
Various virtues such as a very transparent system and the permanent nature of the data which makes it difficult to hack become one of the attractions for the parties to start using the Blockchain in its performance system.
However, as a new system, Blockchain also supports being very vulnerable.
This view was conveyed by professor of computer science from the Massachusetts Institute of Technology (MIT), Professor Stuart Madnick, to the Wall Street Journal, some time ago.
According to Madnick, based on the results of research on hacking cases against the Blockchain system that occurred between 2011 and 2018 with the contribution of aspects.
Starting from approving, arranging distribution, anonymity to technical excellence. "Although the Blockchain is called having a transparent character, where participants can choose within the system, there are still those who have bad intentions and make it possible to hack it," Madnick said.
He said the nature of the Blockchain whose control system is distributed to many parties is a weakness because it cannot be taken when whenever there is an indication of interference.
In the stock exchange system in the capital market industry, for example. There is a central entity that is in control and at any time can take compilation actions that occur, which is by changing the system to a large extent.
"With the Blockchain system that is spread to many points, decentralized, it will be shifted to illegal logging," he said.
Madnick challenges, the community and all parties who are resistant do not rule out various advantages that become the Blockchain's potential to continue to be developed in the future.
It is precisely with the increasingly massive use in the community that it is expected to help the blockchain to improve its security system so that it can reduce the potential for hacking.
"Still, it must also achieve that Blockchain is a new product that promises security and encryption techniques, so that it is feasible to continue to be developed. But don't forget as a new system, Blockchain remains vulnerable, all users need to be vigilant, "Madnick stressed. Two Sides of the Blade of Blockchain Technology
