Ethereum: Byzantium Hardfork running smooth

in #ethereum3 years ago

Today Ethereum has launched the first Metropolis Hardfork - Byzantium !

The Fork went smoothly, all clients are updated, the old chain starved...

While the Bitcoin community is fearing another split by a hardfork, the Ethereum community once again "upgrades" through a hardfork in a comfortable way...

Byzantium, the first of the two Metropolis hardforks was activated today with block 4.370.000.
As it appears, the Fork was a complete success !

Every peer of Ethereum and anyone who runs a node - had to install an update to get on the right chain.
The updates are Geth 1.7.2, Parity 1.7.6,Harmony 1.2 .

Light wallets like Jaxx, Metamask, MyEthereumWallet or Exodus do not need to update, just as little hardware wallets as Trezor or Ledger.

Here you can monitor the Metropolis Byzantium Fork Status:

The Byzantium Fork mainly modifies some very technical parameters so that only the initiates will understand their full significance.

What changes are included in the Byzantium hard fork?

The following upgrades are included:

  • EIP 140 Addition of ‘REVERT’ opcode, which permits error handling without consuming all gas

  • EIP 658 Transaction receipts now include a status field to indicate success or failure

  • EIP 196 Elliptic curve addition and scalar multiplication on alt_bn128
    and pairing checks EIP 197, permitting ZK-Snarks -and other cryptographic mathemagic™

  • EIP 198Support for big integer modular exponentiation , enabling RSA signature verification and other cryptographic applications

  • EIP 211 Support for variable length return values

  • EIP 214 Addition of the ‘STATICCALL’ opcode, permitting non-state-changing calls to other contracts

  • EIP 100 Changes to the difficulty adjustment formula to take uncles into account (EIP 100)

  • EIP 649 Delay of the ice age / difficulty bomb by 1 year, and reduction of block reward from 5 to 3 ether

The second part of the Metroplis-Fork, "Constantinople", has not yet a fixed date, but is expected in 2018.
But It should be expected, however, that this fork at least partly build the foundations for the Casper Proof of Stake contract as well as Sharding.

So far, there is no sign of a minority fork according to current fork logs, and developers are celebrating the transition on social media.

Hard fork celebration!

I found you because I am investing a lot here in the form of technical knowledge, time, creativity and tech hardware as I am now a witness for Steem and I noticed that you are voting for @picokernel - but that picokernel's witness server is offline and of no use to Steem (for quite a long time as far as I can tell).
I would really appreciate if you would support me with a vote to give me a chance to show what I can do for Steem and Steemit. I have a long background in software engineering and also in running social networks.

My witness application post is here.


thank you for this note.
indeed i was very lazy with my witness nomination.
following and supporting.

Ah, great - thanks, I appreciate the support. :)
Followed back!

Yup so far so good, no split in the coin as of yet but we still have about a week for that to still be possible. From what I have found on their site however the conversion over to the new one is moving along quickly with mining power dropping out.

Next I will be very curious what wallets are going to allow the new POS

yes, you are right,... only time will tell.
PoS is not included in this hardfork.

congratulation, we should be expecting etherum to increasing anytime forward

the price will go up 500$

will it be much more difficult to mine ethereum???

yes. the mining block reward is reduced from 5 to 3 eth per block

so that means harder to mine, ups

I like that it didn't completely take off and will gradually show us its magic wonders . Patience is always rewarded

Thanks for giving the chance to enjoy this beautiful news!!

thanks for sharing, it's helpfull....

nice post and thanks for your vote
