Title: How will new nodes be bootstrapped when bitcoin reaches VISA tx volume? Post by: Robert Paulson on March 15, 2014, 01:40:28 PM From what i understand when bitcoin reaches 7000tps each block will be around 1GB in size.
how will then new nodes be boot strapped from scratch? by the time the node finished verifying every transaction since bitcoin's inception the block chain would have already expanded by many new blocks ???

The max block size is currently a thousandth of that and only rarely do blocks even approach that size. Even so, there are already numerous development efforts aimed at reducing the blocksize and speeding up bootstrapping of new clients. Looking up "pruning" would be a good start if you are interested in more details. Title: Re: How will new nodes be bootstrapped when bitcoin reaches VISA tx volume? Post by: Robert Paulson on March 15, 2014, 04:11:39 PM I already read about pruning.
nowhere was it explained how the bootstrapping problem will be resolved. a new node will still have to download the whole unpruned blockchain from an archive node.

That is they only download the block headers (80 bytes each) for the chain, then observe only transactions they care of and validate that they are getting included in new blocks (confirmed). Added: Nodes that want to mine will start up with SPV then upgrade gradually to full node while also pruning spent transactions.

Bitcoin is capable to deal with VISA's volume. https://en.bitcoin.it/wiki/Scalability Title: Re: How will new nodes be bootstrapped when bitcoin reaches VISA tx volume? Post by: Robert Paulson on March 15, 2014, 08:38:00 PM I read the scalability article in the wiki and i understand that most clients will be SPV in the future.
but none of that answers my original question of how new full nodes will be bootstrapped in the future. Title: Re: How will new nodes be bootstrapped when bitcoin reaches VISA tx volume?

If we're only talking a minority of nodes, it would make sense that they would have a decent connection. And it's not like 100 Mbps is exotic right now and we're only at 15 GB total for the blockchain. Title: Re: How will new nodes be bootstrapped when bitcoin reaches VISA tx volume?

I answered your question. Full nodes will start with SPV and upgrade to full verification. Why is the time of convergence to full node important at all?

Full nodes will download all the blocks from the genesis block to the current block. |
