The white paper of TRON was accused of plagiarism. Researchers from Digital Asset Research (DAR) discovered multiple instances of code copied from other projects in the Tron code base. It is also accused of violating the GNU Lesser General Public License v3.0 (LGPL) because the project does not mention that its client was derived from EthereumJ, a Java implementation of Ethereum. These accusations were denied by the TRON Foundation, the organization behind the design of the system.
In 2018, TRON switched its protocol from an ERC-20 token on top of Ethereum to an independent peer-to-peer network. On 25 July 2018, the TRON Foundation announced it had finished the acquisition of Bittorrent, the biggest peer-to-peer file sharing network. Upon this acquisition, in August 2018, BitTorrent Founder Bram Cohen also disclosed that he was leaving the company to found Chia, an alternative to bitcoin created to be a less energy-intensive cryptocurrency.
By January 2019, TRON had a total market cap of about $1.6 billion. Despite this market performance, some authors viewed TRON as a typical case of the complex and disordered nature of cryptocurrencies. In February 2019, after being acquired by Tron Foundation, BitTorrent started its own token sale based on the TRON network.
In May, 2019, the cyber-security testing service HackerOne revealed that just one computer could have brought TRON’s entire blockchain to a halt. The revelation showed that a barrage of requests sent by a single PC could be used to squeeze the power of the blockchain's CPU, overload the memory, and perform a distributed denial-of-service (DDoS) attack.
The TRON protocol, maintained primarily by the TRON Foundation, distributes computing resources equally among TRX holders with internal pricing mechanisms such as bandwidth and energy. TRON provides a decentralized virtual machine, which can execute a program using an international network of public nodes. The network has zero transaction fees and conducts approximately 2,000 transactions per second.[additional citation(s) needed][verification needed]
The implementations of TRON require minimal transaction fees in order to prevent malicious users from performing DDoS attacks for free. In this respect, EOS.IO and TRON are quite similar, due to the negligible fees, high transactions per second, and high reliability, and as such are regarded as a new generation of blockchain systems. Some researchers[who?] defined TRON as an Ethereum clone, with no fundamental differences. The transactions per second rate on Tron's blockchain was questioned because it was far below its theoretical claim.
