Title: The fastest altcoins; Blocks in less than 30 seconds. Post by: Revelation 22:13 on June 04, 2013, 01:59:34 AM Memecoin: (https://bitcointalk.org/index.php?topic=217526.0) 30-second blocks
Digitalcoin: (https://bitcointalk.org/index.php?topic=209508.0) 20-second blocks Worldcoin: (https://bitcointalk.org/index.php?topic=204894.0) 15-second blocks Fastcoin: (https://bitcointalk.org/index.php?topic=218852.0) 12-second blocks Flashcoin: (https://bitcointalk.org/index.php?topic=222450.0) 6-second blocks How fast can we get before it stops working altogether? Title: Re: The fastest altcoins; Blocks in less than 20 seconds. Post by: Foxpup on June 04, 2013, 04:20:30 AM Not very. Fast confirmation times do not improve security at all (assuming equal difficulty, one 10-minute block is as secure as thirty 20-second blocks), and in fact security is reduced significantly by wasting hashpower on more orphaned blocks since network lag is a much bigger factor. The result is that it is possible to do a 51% attack with significantly less than 51% of the hashpower, if the attacker can maintain a low-latency connection to many nodes.

Besides that, how fast can blocks be while still having a stable blockchain?Title: Re: The fastest altcoins; Blocks in less than 20 seconds. Post by: jeannie on June 04, 2013, 06:45:34 AM I think Flashcoin nearly reach the limit. Can't imagine anything faster than that.

Title: Re: The fastest altcoins; Blocks in less than 20 seconds. Post by: muddafudda on June 04, 2013, 08:51:35 AM Memecoin is 30 second blocks, 12 1/2 minute confirms, just nice (25 blocks).
Deliberately kept it up for reasons listed. Title: Re: The fastest altcoins; Blocks in less than 30 seconds. Post by: Revelation 22:13 on June 04, 2013, 08:55:54 AM Added.

Post by: ezcoin on June 04, 2013, 08:59:19 AM Although I think smaller block times are possible, there's the problem of the block chain growing too quickly. For that reason I chose 60 seconds for EZCoin. Personally I think it is a nice balance.
