Litecoin
Litecoin is often referred to as the silver to bitcoin’s gold. Albeit not everyone may see it that way, Litecoin brings some very intriguing developments in the world of cryptocurrency, that much is certain. Compared to bitcoin’s block time, Litecoin generates network blocks 4 times as fast on the network. It takes an average of 2.5 minutes for this process to complete, which is quite an improvement.
Monero
For a cryptocurrency that offers privacy and anonymity features, Monero has proven to be quite a “quick” altcoin when it comes to generating new blocks on the network. With an average block time of just two minutes, Monero succeeds in providing users with anonymity features at 1/5th of the time bitcoin generates a block, which does not include any anonymity features.
It is interesting to note Monero used to have an even faster block time at one point in time. The developers decreased the block time to 60 seconds when Monero was first launched, yet they reverted it back to 120 seconds once the network started to settle. While 60 second block times may sound more preferable, 120 seconds does the job just fine for Monero.
Ethereum
Many people believe Ethereum is the world’s fastest cryptocurrency in terms of block generation time, but that is not the case It has to be said, Ethereum is somewhat in a league of its, with the average block time sitting at the 14 second mark ever since April of 2016. It is quite an impressive feat to see Ethereum keep the block time so low. Bitcoin users would like to see a similar strategy introduced by the developers, albeit it is doubtful that will happen anytime soon.
Ripple
When it comes to generating blocks quickly, there is no competition for Ripple right now. Although Ripple is targeting a very different crowd compared to bitcoin, Monero, or the other coins mentioned above, the technology powering this network has proven to be quite solid. The average Ripple network block is generated in as little as 3.5 seconds.
Considering how Ripple is aiming to change the world of finance by collaborating with financial institutions all over the world, that 3.5 second mark is quite important. Blockchain-based assets are designed to make transactions more efficient. Ripple succeeds in allowing for very fast transfers at minimal fees, whereas bitcoin seems to get slower and more expensive until the scalability issue is addressed.
