Recent data suggests that 2018 was a bad year for a large number of dApps. According to data from State of the dApps, around 17 percent of dApps have apparently been abandoned.
The data shows that 17.2% of the dApps on ETH, EOS, and STEEM networks have had no activity whatsoever in the last 12 months. This leads them to be classified as "abandoned" by the site.
After the huge success of CryptoKitties on the ETH blockchain back in 2017, the predicted explosion in the dApp market never really came about. Throughout the year there have been reports of how little activity many dApps are seeing, and the fact that gambling platforms with relatively basic mechanices are regularly the most popular dApps by a significant margin has also been a disappointment for what was supposed to be an exciting new avenue for the blockchain space.
December 2018 was a good month for the development of #dapps (decentralized applications). We received 179 new DApp submissions, an all time high! https://t.co/EF9GurjFBd (1/3) pic.twitter.com/M2Mb3R5wag— State of the DApps (@StateOfTheDApps) January 4, 2019
However, this recent data doesn't give the full picture, as many of the most popular dApps are now on the Tron (TRX) network, which isn't included in this anaylsis. Tron has reported growth across many of its decentralized applications recently, with dice game TronDice consistently ranking as the most popular dApp in the space. Also, the number of submissions for new dApps was at an all-time high in 2018, which suggests new software coming in to take the place of the less popular applications from previous years.
