1 transaction block how its possible?

[picolo]

I've seen 0 sent blocks on blockchain

I thought there was always at least one transaction : the transaction to send the mining reward.

Random algo starts at 0, so we can expect blocks with 0 transactions or just a few transactions with low amounts, yet the reward is still there. Ones all coins get found, things change, miners get rewarded with the fee, so not sure what will happen by then (on 2050 approx.).

You are mistaken.  The last block subsidy won't occur until 2140.

It's a network consensus rule that all blocks have to have at least one transaction (the coinbase transaction), and the first transaction has to be a coinbase transaction (1 input with a Null previous output). The relevant code: https://github.com/bitcoin/bitcoin/blob/v0.10.0rc3/src/main.cpp#L2462-L2465

Also, for anyone interested, I did a writeup on the reasons that miners would be incentivized to only include their reward transaction on the Bitcoin Stack Exchange. The link is below. I found that of recent blocks, 1.3% have only the reward transaction, and 1.6% have fewer than 10 transactions in them.

Miners can choose what transactions they want to include. If they don't want to include any transactions other than the one that pays them their 25 BTC, then that's their choice.

Haha what an effective and good answer! Good job.

PS. Why don't we have a tip bot for comments on this forum?

There is no tip bot, but I guess the Bitcoin address of the users are listed on their profile page, so we can tip anyway.

It takes a bit longer than tipbot, but if you really want to tip, that works.
