Bitcoin Maturation
Posted:Thu 01 of Oct, 2009 (14:12 UTC)

From the user's perspective the bitcoin maturation process can be broken down into 8 stages.

1. The initial network transaction that occurs when you first click Generate Coins.
2. The time between that initial network transaction and when the bitcoin entry is ready to appear in the All Transactions list.
3. The change of the bitcoin entry from outside the All Transaction field to inside it.
4. The time between when the bitcoin appears in the All Transfers list and when the Description is ready to change to Generated (50.00 matures in x more blocks).
5. The change of the Description to Generated (50.00 matures in x more blocks).
6. The time between when the Description says Generated (50.00 matures in x more blocks) to when it is ready to change to Generated.
7 The change of the Description to Generated.
8. The time after the Description has changed to Generated.

Which stages require network connectivity, significant local CPU usage and or significant remote CPU usage? Do any of these stages have names?

As far as I know, there's no network transaction when you click Generate Coins - your computer just starts calculating the next proof-of-work.  The CPU usage is 100% when you're generating coins.

In this example, the network connection is used when you broadcast the information about the proof-of-work block you've created (that which entitles you to the new coin). Generating coins successfully requires constant connectivity, so that you can start working on the next block when someone gets the current block before you.

It's important to have network connectivity while you're trying to generate a coin (block) and at the moment it is successfully generated.

1) During generation (when the status bar says "Generating" and you're using CPU to find a proof-of-work), you must constantly keep in contact with the network to receive the latest block. If your block does not link to the latest block, it may not be accepted.

2) When you successfully generate a block, it is immediately broadcast to the network.  Other nodes must receive it and link to it for it to be accepted as the new latest block.

Think of it as a cooperative effort to make a chain.  When you add a link, you must first find the current end of the chain.  If you were to locate the last link, then go off for an hour and forge your link, come back and link it to the link that was the end an hour ago, others may have added several links since then and they're not going to want to use your link that now branches off the middle.

After a block is created, the maturation time of 120 blocks is to make absolutely sure the block is part of the main chain before it can be spent.  Your node isn't doing anything with the block during that time, just waiting for other blocks to be added after yours.  You don't have to be online during that time.

Warning: necro

Remember when it was as easy as "click generate?" Even then, very few people did, and often those that did, like myself, didn't do it for very long.

It has taken enormous amounts of work to make Bitcoin into something worth the serious effort of miners. Bitcoin still has a long way to go to grow into a robust high volume transaction network affordable by all. I hope we get there. I think we will.

Being able to say I was in this thread and got to read these words == better than any bitcoin I could ever earn or receive.  We hope you're just one guy or perhaps a small group among us.  Seems from your writing that you're just one guy, you probably never check these stomping grounds out anymore.  I wouldn't expect you to.
