Hi.

I am currently working on a Bitcoin Protocol presentation and I have to start from the basics. Someone told me, while going through my presentation, that the reward system has changed from 210,000 blocks / 2 weeks with the last of the bitcoins being released into the system in 2140. He informed me that the process of mining is now faster and that the last bitcion may be released sooner than 2140. I would like my presentation to be as up-to-date as possible but I keep getting my initial find when I search the internet. Articles are however 2 or more months old and a lot could have changed from that time. If anyone knows of these changes, could you please enlighten me? A reference would be awesome in this case. Thank you in advance.

Cheers,
Lista.
