Ethereum block time change

The above discussion is related to the homestead ethereum release — not the frontier. Following shows the difficulty calculation used in frontier. So, to keep ethereum block time at a considerable level, the computational power also must increase with the time to match the difficulty bomb — if not, it will be hard to mine ethereum, which will result in a ethereum blockchain freeze — also known as ice age.

The Ethereum Difficulty Bomb The ethereum difficulty bomb, which makes mining harder with an exponentially increasing difficulty level over the time was introduced to discourage the miners to continue mining with proof of work mining, when the ethereum serenity release in the future introduces proof of stake mining.

The difficulty level was introduced with the first patch to the ethereum frontier. Frontier was the initial release of ethereum, pushed live in July Anyway, between these two releases, even though the difficulty algorithm got changed, there was no change to the difficulty bomb part.

With the changes to the ethereum difficulty algorithm to support the difficulty bomb, starting from block , around Sept, , the difficulty increased exponentially, but only became noticeable in about a year later. At that point onwards there is a significant increase in difficulty which started pushing the block resolution time upwards.

As we go on like this, due to the harder mining targets the network will continue to be useful for roughly few months, but eventually will reach an ice age, where the difficulty will simply be too high for anyone to find a block. The plan was to introduce proof of stake at that point with the ethereum serenity release. As the plans for the serenity release got delayed, there is a hard fork expecting with the byzantium release still with proof of work , in the ethereum network, in couple of days time between UTC and UTC on Monday, October 16, , at the block number 4,, Byzantium is part of the metropolis ethereum development phase that includes two hard forks: byzantium and constantinople.

Constantinople does not currently have a release date, but is expected in With the EIP proposal, which includes in byzantium, the ethereum difficulty bomb is further delayed. Now, the average block time is This EIP Ethereum Improvement Proposal is suggesting to delay the difficulty bomb significantly, to reduce the average block time below 15 seconds, and to allow more time for serenity development.

Bitcoin tries to maintain its block time to be around 10 minutes with its difficulty algorithm. Why it is 10 minutes? Why not 2 or 20 minutes? The very first reference of having 10 minutes as the bitcoin block time comes from the original research paper , which introduced bitcoin in , by Satoshi Nakamoto.

It has only one reference, and 10 minutes is not a concrete suggestion, but takes as an example. A block header with no transactions would be about 80 bytes. This value of latency is independent of the block time. All the miners in the network mine simultaneously and independently. So, in the above function of wastage, the number of is will go down — so the wastage.

If the value of t is 2 minutes, and then every miner who completes mining a block before 3 minutes time period with 1 minute network latency will only contribute to the waste except the miner who finishes very first and gets the reward. Here you can see, there is a Considering all the other factors, Satoshi Nakamoto thinks the wastage at the 10minutes block time is acceptable.

Along with the wastage, if multiple nodes start generating the same block simultaneously or within a short period of time, this will lead into multiple and more frequent bitcoin forks. Frequent folks, will make the bitcoin network less healthy, and the transaction confirmation time will increase, as everyone has to wait till the bitcoin network becomes eventually consistent. Note: In the above calculation 1 minute of network latency was taken just as an example to make the math easier.

A paper by Decker and Wattenhofer in Zurich measures bitcoin network latency, and determines that If the the story we built in the previous section is true, how would ethereum reduce the wastage with such a low block time — and also reduce the chance of multiple, frequent forks. The GHOST is an innovation first introduced by Yonatan Sompolinsky and Aviv Zohar in December , and is the first serious attempt at solving the issues preventing much faster block times.

As discussed in the previous section, the main challenge in shorter block time is, there will more miners producing the same block, and end up with no economic incentives — and waste a lot of computational power with no impact towards the stability of the network.

Further, this will result in more frequent forks. When a fork happens, the network proceeds by finding the longest blockchain and every miner will switch to it. In ethereum these blocks are known as uncle blocks. An uncle block receives some percentage of the normal block reward — so the computational power spent on mining the stale blocks are not wasted with no economic incentives.

Then the question is, why it is not 1 second? Ethereum picks the block time be between 10 to 19 seconds because that is as fast as possible, but is at the same time substantially longer than network latency. Another reason is, in ethereum not all uncle blocks are rewarded — and the block time should not encourage more uncle blocks than what can be rewarded.

Before the Merge, Ethereum only knew probabilistic finality. This means that changing a block becomes exponentially more difficult over time but is never impossible. Post-Merge, Ethereum now offers deterministic finality. After every 32 blocks 6. Only exception: Should an actor own one-third of the total staked ETH, he or she can change justified blocks despite transaction finality.

It will be triggered by a metric called terminal total difficulty TTD. Once this metric surpasses a certain height, Ethereum will switch from building blocks using PoW to building blocks with PoS without interruption. All this is assuming that the transition works according to plan and with no unexpected interruptions. Ether that has been staked directly on the Ethereum Beacon Chain cannot be withdrawn after the Merge.

Only after the release of the Shanghai update, which is scheduled to take place a few months after the Merge early , will stakers be able to withdraw their staked ETH. Nevertheless, there exists the possibility to trade some of the staked Ether coins. Lido is a decentralized staking Protocol that allows investors to pool their ether. This allows users to stake ether without having to come up with the 32 ether required to run a personal validator node.

Note: Investors staking their ether through centralized exchanges CEXs might be subject to different withdrawal conditions and can potentially withdraw their staked ether earlier, depending on the exchange. Pre-Merge, the Ethereum network had to pay its miners for their energy-intensive and costly work.

For this, the network issued approximately 13, additional ETH per day. As miners are no longer needed post-Merge, the daily ether issuance will drop to 1, ETH per day, which adds up to a yearly inflation rate of approximately 0. Additionally, the Ethereum network has introduced a burning mechanism, which burns destroys a fraction of all gas fees. Depending on the average network usage, Ethereum could even become a deflationary currency in the future. Everyone can run a node in the Ethereum network.

No ether ETH is required to participate in the Ethereum network and sync a personal self-verified copy of the Ethereum blockchain.
