测试发现,Ethereum缩放修复将创建一个块的时间缩短了一半

据第三方测试人员介绍,BloXroute Labs是一家专注于可伸缩性的区块链初创企业,它成功地将Ethereum mainnet上的块传播时间缩短了一半。


区块链咨询公司Akomba实验室跑bloXroute“区块链分布网络”(BDN) Ethereum节点在新加坡11月11日至11月27日,发现平均块传播时间——时间一块需要生产和共享整个区块链——降至172毫秒,不到一半的当前平均时间360毫秒。


Akomba使用了来自中国一个采矿池的数据作为为期两周的测试的一部分。


Akomba的结果表明,BDN可能对Ethereum mainnet中的块传播产生有限但潜在的级联效应,Ethereum mainnet是最大的公共区块链之一,也是交易成本较高的区块链之一,天然气价格约为20美分。它也是可伸缩性争论中的一个常见目标。


bloXroute首席执行官Uri Klarman表示:“Ethereum比其他任何区块链都更能感受到可伸缩性瓶颈的影响。”“它正在失去动力,失去市场份额。他们感觉到了问题。大多数人没有。”


BloXroute的方法是一个0层解决方案,它减少了事务大小,从而加快了块传播时间。例如,BDN可以为一个500字节的事务广播4个字节。


Klarman说:“我们不会发送整个数据块,因为如果其他网关知道那里的事务,你就不需要发送实际的数据本身——只需要指示那里有哪些事务的指针。”


BloXroute之前曾在9月份在以太网上测试过BDN,结果也类似。当时,它的块传播时间减少了25%。


Klarman表示,BDN已经在一些大型矿池中运行,并将继续逐步引入大型矿池。他表示,一旦建成,阻塞容量将增加,费用可能下降——如果新增容量超出网络需求的话。


去年9月,以太坊的矿工投票决定将天然气上限提高到1,000万桶,比之前的上限高出25%。此举是为了应对网络拥堵,卡拉曼表示,需求立即吞噬了额外的空间。


他表示:“我们知道这些交易有需求,这让我们走到了目前的位置。”

 

BloXroute Labs, a scalability-focused blockchain startup, was successfully able to reduce block propagation time on the Ethereum mainnet in half, according to a third-party tester.

Blockchain advisory firm Akomba Labs ran bloXroute's "Blockchain Distribution Network" (BDN) on an Ethereum node in Singapore between Nov. 11 and Nov. 27, finding that average block propagation time – the time a block needs to be produced and shared throughout a blockchain – dropped to 172 milliseconds, less than half the current average time of 360 milliseconds.

Akomba utilized data from a Chinese mining pool as part of the two-week test.

Akomba’s results indicate BDN could have a modest but potentially cascading effect on block propagation in the Ethereum mainnet, one of the largest public blockchains and one of the more expensive to transact on, with gas prices around 20 cents. It is also a frequent target in the scalability debate.

“Ethereum feels the burn of the scalability bottleneck more than any other blockchain out there,” said Uri Klarman, bloXroute CEO. “It's losing momentum, it's losing market share. They feel the problem. Most others don't.”

BloXroute’s approach is a layer 0 solution that reduces transaction size and thus speeds up block      propagation time. BDN could broadcast 4 bytes for a 500 byte transaction, for example.   

“We don't send the entire block because if the other gateways know the transaction out of there, you don't need to send the actual data itself – only pointers saying which transactions are there” said Klarman.

BloXroute had previously tested BDN on the ethereum mainnet in September to similar results. At the time, it clocked about 25 percent reduction in block propagation time.

Klarman said that BDN is already running in some large mining pools and will continue to be gradually introduced to larger pools. Once it does, he says block capacity will increase and fees could fall – if, that is, the added capacity outstrips network demand. 

In September, ethereum miners voted to raise the GAS limit to 10 million, up 25 percent from the previous ceiling. That move was made to combat network congestion, and Klarman said demand immediately ate the extra space up.

“We know there is demand for these transactions, which lead us to where we are right now,” he said.
