The overcoming of the block height 20,000,000 on the Tron blockchain was announced today.
The first block was validated on June 25th, 2018, just under two years ago, but at the rate of a new block every few seconds, tens of thousands are validated every day.
So it is not surprising that more than 20 million blocks have been validated in less than two years, compared, for example, to the approximately 630,000 Bitcoin blocks in more than eleven.
The curious thing, however, is that the Ethereum blockchain, whose blocks are validated in less than 15 seconds, the mined blocks are only just over 10 million, despite the fact that the first block was mined on July 30th, 2015, just under five years ago.
The thing is that the TRON blockchain is not based on Proof of Work, like that of Bitcoin or Ethereum, and so it is much quicker in validating blocks.
This is one of the reasons why Ethereum is planning to move to Proof of Stake as soon as possible, so that it can handle many more blocks and much faster, in order to support a higher volume of transactions.
For example, more than one billion transactions have already been recorded on the TRON blockchain in two years, whereas on the Ethereum blockchain just over 700 million and on the Bitcoin blockchain, about 530 million.
Therefore, from a strictly technical point of view, it is possible to say that the TRON blockchain is supporting a higher volume and speed of transactions than those of Ethereum, or Bitcoin, even though Bitcoin is not comparable in almost anything to TRON. Instead, its real competitor is Ethereum.
Of all the major blockchains, only EOS supports a higher transaction volume of over 2 billion and probably not by chance, since EOS, TRON and Ethereum are the preferred blockchains for dApps.
XRP also supports a very high number of transactions but is not particularly used for dApps.
