Ethereum [ETH] Ropsten Constantinople hard fork failure discussed by Foundation’s Hudson Jameson

Hudson Jameson, a member of the Ethereum Foundation, recently spoke about the major issues faced during Ethereum Ropsten Testnet Constantinople hard fork, during a discussion with EthHub. According to the latest announcement, the Constantinople hard fork is scheduled to take place on block #7,280,000 around February 27, 2019. The initial hard fork, which was scheduled to take place around January 16, 2019, was delayed due to issues with one of the five proposed Ethereum Improvement Protocols. EIP 1283: the net gas metering for SSTORE without dirty maps had potential of enabling a Reentrancy attack on smart contract after Constantinople hard fork. This lead to the Foundation concluding that it would be best to postpone the upgrade until a solution is found. Notably, this is not the first time Constantinople hit the pause button. The hard fork was initially scheduled to take place towards the end of 2018. However, the team encountered issues during the Ropsten Testnet hard fork launch. According to the post-mortem report of the Ropsten Constantinople Testnet, there was a bug identified in the Parity implementation of Ethereum. In addition, there were problems encountered with difference between Parity and Geth consensus. On this, Hudson Jameson stated that the Testnet split because of the issues between Geth and Parity, and that the fork occurred during the weekend, which was contrary to their planning. He stated that they timed it incorrectly as block times “can be tricky to nail down.” This, in turn, resulted in a delay in fixing the Testnet. According to him, one of the main reasons it failed was the lack of preparation. The absence of miners ready to mine the new chain was also one of the problems encountered during the fork, Hudson stated; “The circumstances around it and if you just go to the really deepest level of why things are the way they are and why there are so many inefficiencies, it’s because a lot of us are very developer heavy, within the core developer ecosystem and we don’t have a lot of people with traditional or enterprise management experience” He further stated: “But then once you start to plan things, we have other tasks that we’re dealing with than our respective foundation or respective jobs. So that makes it more difficult for us to go in and have the right skill set to actually organize appropriate hard fork. We don’t have project management experience in a traditional sense.” The post Ethereum [ETH] Ropsten Constantinople hard fork failure discussed by Foundation’s Hudson Jameson appeared first on AMBCrypto.

Ethereum [ETH] Ropsten Constantinople hard fork issues unveiled by core developer

Recently, Lane Rettig, an independent core developer of Ethereum [ETH] posted a “post-mortem” report and his concerns regarding the Constantinople hard fork on Ropsten Testnet. The report covered the various issues discovered during the hard fork, which was set to be implemented by the end of October 2018. According to the report, a consensus bug was discovered in Parity implementation of Ethereum. He explained the reasons why the bug was not discovered by the Ethereum testers and why the consensus bug occurred. Rettig added: “Apparently, in this case, there was some confusion over the meaning of terms like ‘transaction’ and ‘execution frame’ that may have contributed to the bug.” In addition, there were concerns regarding the absence of miners on Parity, Geth, or Aleth for Ropsten. During that timeframe, Afri Schoedon, a developer posted a Tweet asking for miners to reach out to run mining hashrate on Parity 2.0.7, 2.1.2 or Geth 1.8.17 “configured for Ropsten”. Rettig opined that there had to be a better understanding and control over mining on a Proof-of-Work [PoW] Testnet. He further stated that Parity had a limit on “how far back nodes could automatically reorganize themselves”. This was because the fork was too long for Parity Ethereum nodes, as stated by Afri Schoedon. Rettig added that understanding this mechanism was important as Parity has the limit, which is absent in Geth. Furthermore, Geth had a debug.setHead command which allowed users to manually force it onto the right chain whereas Parity did not have any such feature. He added: “Is this supposed to be a limit on ‘on chain governance’ [allowing nodes to automatically come to consensus on the canonical chain] that triggers the need for meatspace/developer intervention? Or is it more about resource constraints? What’s the limit and why is it set as such?” He added: “It’s possible for an upgraded node in fast sync mode (geth or parity, I believe) to fast sync over a bad block which caused a fork and keep following the wrong chain. This is clearly the shortcoming for fast sync but we should discuss this in the context of forks and long reorgs…” Furthermore, Rettig stated that Ropsten currently has four chains and that it is very difficult for a node to sync from scratch in order to find the right chain. This is due to the peering process occurring on the wrong chain. He stated: “In this case, it was necessary for nodes to turn off discovery entirely and manually enter a set of peers to get caught up to the right chain” Another concern raised by Rettig was that the AllCoreDevs channel on Gitter served as the primary means of communication throughout the hard fork but this was disorganized and had no threading. It was further difficult to find a canonical source of information. According to Rettig, it was necessary to create a core developer “War Room” where this information could be managed during an upgrade or any other emergent situation. He also stated that since the launch of Constantinople hard fork on Ropsten Testnet till press time, Ropsten was effectively unusable or very difficult to use. In addition, they were still expecting to have several active forks. He added: “This begs the question, what is a testnet? What is its purpose? Do we need stable, ‘production’ testnets and ‘staging’ testnets?” The post Ethereum [ETH] Ropsten Constantinople hard fork issues unveiled by core developer appeared first on AMBCrypto.

IOTA Introduces Permanode Tech For Long-Term Data-Storage

The IOTA Foundation is taking a major step towards ensuring permanency in the Tangle, announcing a “Permanode” technology called Chronicle. IOTA is designed as a protocol for the permissionless and frictionless exchange of value between machines and humans, with the Tangle acting as a distributed ledger. Using the new permanode technology, users will be able to securely store data, where it will be  “verifiable to third parties for free.”   While some data doesn’t need to be stored for years, decades, or lifetimes, certain sorts of data require greater permanence. “For example,” the IOTA blog explains, “financial data must be stored for 10 years in some cases, and identity data needs to be kept for the lifetime of the identity.”  The IOTA Foundation describes the new permanode technology as a “crucial building block” for enabling these types of use-cases. The Foundation describes Chronicle as the “official permanode solution,” enabling easy access to the Tangle’s entire history, which is stored indefinitely via the technology.  The system is described as a “distributed fault-tolerant permanode that scales out and up…”     source: IOTA Foundation   Chronicle has some unique and interesting use-cases for community members and businesses, such as offering “query as a service.” Node owners might find a new stream of revenue charging IOTA tokens to access Tangle data. Further services could be added through “Multiplex networks,” offering “microservices… that can communicate with public and private dataset(s) under different policies.”  Chronicle is due for a third-party audit to ensure it is ‘water-tight’ before it is released to the public. The IOTA Foundation invites community members to take part in the work, with grants available for “developing and expanding the notion of permanodes.”   source: CoinMarketCap   IOTA joined the altcoin surge today, enjoying a healthy bump of more than 14% in value against USD and BTC over the past 24 hours. The token has enjoyed a positive week, with over 10% growth in USD price over the past seven days.   The post IOTA Introduces Permanode Tech For Long-Term Data-Storage appeared first on Crypto Briefing.
