We are pleased to release Litecoin Core 0.15.1 release. This is a new minor version release, including new features, various bug fixes and performance improvements, as well as updated translations. It is recommended for all users to upgrade to this version.

A number of changes to the way Litecoin Core deals with peer connections and invalid blocks have been made, as a safety precaution against blockchain forks and misbehaving peers.

  • Unrequested blocks with less work than the minimum-chain-work are now no longer processed even if they have more work than the tip (a potential issue during IBD where the tip may have low-work). This prevents peers wasting the resources of a node.
  • Peers which provide a chain with less work than the minimum-chain-work during IBD will now be disconnected.
  • For a given outbound peer, we now check whether their best known block has at least as much work as our tip. If it doesn’t, and if we still haven’t heard about a block with sufficient work after a 20 minute timeout, then we send a single getheaders message, and wait 2 more minutes. If after two minutes their best known block has insufficient work, we disconnect that peer. We protect 4 of our outbound peers from being disconnected by this logic to prevent excessive network topology changes as a result of this algorithm, while still ensuring that we have a reasonable number of nodes not known to be on bogus chains.
  • Outbound (non-manual) peers that serve us block headers that are already known to be invalid (other than compact block announcements, because BIP 152 explicitly permits nodes to relay compact blocks before fully validating them) will now be disconnected.
  • If the chain tip has not been advanced for over 7.5 minutes, we now assume the tip may be stale and will try to connect to an additional outbound peer. A periodic check ensures that if this extra peer connection is in use, we will disconnect the peer that least recently announced a new block.
  • The set of all known invalid-themselves blocks (i.e. blocks which we attempted to connect but which were found to be invalid) are now tracked and used to check if new headers build on an invalid chain. This ensures that everything that descends from an invalid block is marked as such.

The minimum relay fee -minrelayfee has been lowered to 0.01 lites per kB (0.00001 LTC). This is to prepare for dropping the minimum transaction fee to 0.1 lites per kB (0.0001 LTC) in the next release.

Mempool replacement --mempoolreplacement has been disabled by default.

Though blockmaxweight has been preferred for limiting the size of blocks returned by getblocktemplate since 0.13.0, blockmaxsize remained as an option for those who wished to limit their block size directly. Using this option resulted in a few UI issues as well as non-optimal fee selection and ever-so-slightly worse performance, and has thus now been deprecated. Further, the blockmaxsize option is now used only to calculate an implied blockmaxweight, instead of limiting block size directly. Any miners who wish to limit their blocks by size, instead of by weight, will have to do so manually by removing transactions from their block template directly.

The GUI settings will now be written to guisettings.ini.bak in the data directory before wiping them when the -resetguisettings argument is used. This can be used to retroactively troubleshoot issues due to the GUI settings.

Previously, it was possible to open the same wallet twice by manually copying the wallet file, causing issues when both were opened simultaneously. It is no longer possible to open copies of the same wallet.

A hidden debug argument -minimumchainwork has been added to allow a custom minimum work value to be used when validating a chain.

  • The “currentblocksize” value in getmininginfo has been removed.
  • dumpwallet no longer allows overwriting files. This is a security measure as well as prevents dangerous user mistakes.
  • backupwallet will now fail when attempting to backup to source file, rather than destroying the wallet.
  • listsinceblock will now throw an error if an unknown blockhash argument value is passed, instead of returning a list of all wallet transactions since the genesis block. The behaviour is unchanged when an empty string is provided.

Bitcoin Price to $1 Million in 10 Years ‘Very Reasonable’ Says Kraken CEO

Republished by Plato

Published

on

With bitcoin currently enjoying a near 70% YTD increase, bullish predictions see the asset topping into a six or even seven-digit territory in the following decade. These projections came recently from Kraken’s CEO, Jesse Powell, and the Managing Director of Magnetic, William Quigley.

Bitcoin to $150K in the Next Year

Founded in 2010, Magnetic is an investment firm with a pro-cryptocurrency approach, having allocated funds in the industry as well. In a CNN appearance, the company’s Managing Director and Co-Founder, William Quigley, spoke about bitcoin’s future, price performance, and the impact of the COVID-19-induced financial crisis on the asset.

By referring to historical price developments after each halving, the executive forecasted a somewhat bullish projection that can take the cryptocurrency up to $150,000 in the following months.

“We are about half-way through the post-halving bull run, so, by my judgment, we have a lot more to go with bitcoin. Certainly – $100,000 and quite possible $150,000 by the end of this year or maybe Q1 next year.”

Quigley also touched upon the growing number of companies putting BTC on their balance sheet, which he classified as “huge.” He believes that the general narrative for corporations to allocate some of their trillions of dollars currently held in cash in government bonds is fading. Instead, they will continue to look for an asset with a finite supply, namely bitcoin.

He noted that the most critical issues for corporations are inflation and the diminishing of the dollar. In contrast, being a limited-supply type of asset, BTC could serve as a hedge with its decreasing inflation.

BTC to $1M, Says Kraken CEO

In another widely-bullish prediction, Jesse Powell, the CEO of the US veteran crypto exchange Kraken, said that the asset price is going to “infinity.”

When asked to specify in dollar terms what that amount would represent, Powell said that even reaching $1 million per bitcoin sounds “reasonable.”

“People that are believers in bitcoin see it’s going to replace all of the world fiat currencies, so that means basically whatever the market cap of the dollar is, the euro, all of that combined is what bitcoin could be worth.

In the near time, people see it surpassing gold as a store of value. So, a million dollars as a price target within the next ten years is very reasonable.”

He justified his quite optimistic prediction with the excessive amounts of fiat currencies printed by the US and other global superpowers following the COVID-19 pandemic. Additionally, Powell believes that the younger generations are keen to adopt the primary cryptocurrency, which could skyrocket its price.

First Major Rug Pull on Binance Smart Chain? Over $30 Million Drained

Republished by Plato

Published

on

  • Binance Smart Chain has become somewhat of a hot topic amid DeFi gem seekers in the past few weeks.
  • The network saw an influx of new projects, reminiscing of the early days of the DeFi craziness last summer.
  • In any case, hours ago, the community was shocked earlier today when news broke out that one of the newer protocols, Meerkat Finance, was drained.
  • Meerkat Finance is a yield farming protocol that runs on Binance Smart Chain, and a few hours ago, the team revealed that it was “hacked” and drained by 73,000 BNB and 13 million BUSD. The total number amounts to roughly over $30 million at the time of this writing.
  • It appears that the alleged hacker stole the money by changing the protocol’s smart contract using the original deployer’s account. In other words – the private key of the deployer contract must have been compromised.
  • The Twitter account of the project, as well as the website, have also been taken down, causing some to believe that the team rug pulled the entire thing.
  • Meanwhile, the official account of Binance prompted the community to provide any additional information they may have on the case.

Parity To Educate Berkeley Students on Developing Blockchain Projects on Polkadot

Republished by Plato

Published

on

The popular DLT protocol Parity Technologies has partnered with Berkeley’s Blockchain Xcelerator program to provide educational panels for students in the university’s blockchain curriculum.

As part of the collaboration, Polkadot’s co-founder Gavin Woods will be a guest lecturer in the A. Richard Newton Distinguished Innovator Lecture Series.

Parity to Educate Berkeley Students About Blockchain

Parity Technologies, a core DLT infrastructure company, announced its latest partnership in a press release shared with CryptoPotato.

According to the document, Parity will employ its substrate blockchain-building framework to educate and work together with the university to raise “the overall awareness of next-generation blockchain technologies in order to promote adoption among students and the community at UC Berkeley.”

For the ongoing 2020-2021 academic year, Parity’s developer education team will collaborate with the faculty, students, and the community studying blockchain technologies in their respective coursework. This includes involvement in curriculum preparation, project ideas, and resources to “enrich the educational experience.”

Furthermore, Parity and the university’s DLT-oriented program called the Berkeley Blockchain Xcelerator will advise students and entrepreneurs on how to develop and eventually launch blockchain startups on Polkadot and Web 3.0 ecosystem.

Jocelyn Weber, an executive at the Berkeley Blockchain Xcelerator, said that the “work with parity and other Polkadot ecosystem startups had demonstrated the potential of this technology in educating our community.”

“We strive to expose our students to the tools and skills they will need to enter this space and immediately start making significant contributions – which is why improving their knowledge with tools such as Substrate and networks like Polkadot will be an important part of our curriculum development.” – Weber added.

Gavin Woods to Give a Lecture

The statement also outlined that Dr. Gavin Woods, the co-founder of Ethereum, Polkadot, and Parity, will give a lecture in the A. Richard Newton Distinguished Innovator Lecture series this month.

Wood commented that blockchain innovation is expanding at a rapid pace and has advanced “beyond legacy networks into next-generation, production-grade blockchains like Polkadot.” This makes it “critical” for the newer coders, engineers, and entrepreneurs to be able to take on the growing competition and develop ground-breaking projects.
