Litecoin Core v0.17.1 Release Candidate

Follow the Google+ page or Twitter for the latest dev news.

We are pleased to release Litecoin Core 0.17.1 release candidate. This is a new major version release, including new features, various bug fixes, performance improvements and updated translations.

It is recommended for power users to upgrade to this version. After sufficient testing, Litecoin Core 0.17.1 final will be released and is recommended for all users to upgrade.

If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/Litecoin-Qt (on Mac) or litecoind/litecoin-qt (on Linux).

If your node has a txindex, the txindex db will be migrated the first time you run 0.17.1 or newer, which may take up to a few hours. Your node will not be functional until this migration completes.

The first time you run version 0.15.0 or newer, your chainstate database will be converted to a new format. This will take anywhere from a few minutes to half an hour depending on the speed of your machine.

Note that the block database format also changed in version 0.8.0 and there is no automatic upgrade code from before version 0.8 to version 0.15.0. Upgrading directly from 0.7.x and earlier without redownloading the blockchain is not supported. However, as usual, old wallet versions are still supported.

The chainstate database for this release is not compatible with previous releases, so if you run 0.15 and then decide to switch back to any older version, you will need to run the old release with the -reindex-chainstate option to rebuild the chainstate data structures in the old format.

If your node has pruning enabled, this will entail re-downloading and processing the entire blockchain.

Litecoin Core is extensively tested on multiple operating systems using the Linux kernel, macOS 10.10+, and Windows 7 and newer (Windows XP is not supported).

Litecoin Core should also work on most other Unix-like systems but is not frequently tested on them.

From 0.17.1 onwards macOS <10.10 is no longer supported. 0.17.1 is built using Qt 5.9.x, which doesn’t support versions of macOS older than 10.10.

Known issues

  • Upgrading from 0.13.2 or older currently results in memory blow-up during the roll-back of blocks to the SegWit activation point. In these cases, a full -reindex is necessary.
  • The GUI suffers from visual glitches in the new MacOS dark mode. This has to do with our Qt theme handling impacting older versions of Litecoin Core, but is expected to be resolved in 0.17.1.

The listtransactions RPC account parameter has been renamed to label.

When litecoin is configured with the -deprecatedrpc=accounts setting, specifying a label/account/dummy argument will return both outgoing and incoming transactions. Without the -deprecatedrpc=accounts setting, it will only return incoming transactions (because it used to be possible to create transactions spending from specific accounts, but this is no longer possible with labels).

When -deprecatedrpc=accounts is set, it’s possible to pass the empty string “” to list transactions that don’t have any label. Without -deprecatedrpc=accounts, passing the empty string is an error because returning only non-labeled transactions is not generally useful behavior and can cause confusion.

  • -includeconf=<file> can be used to include additional configuration files. Only works inside the litecoin.conf file, not inside included files or from command-line. Multiple files may be included. Can be disabled from command- line via -noincludeconf. Note that multi-argument commands like -includeconf will override preceding -noincludeconf, i.e.

as litecoin.conf will still include relative.conf.

  • Block storage can be limited under Preferences, in the Main tab. Undoing this setting requires downloading the full blockchain again. This mode is incompatible with -txindex and -rescan.

The -wallet=<path> option now accepts full paths instead of requiring wallets to be located in the -walletdir directory.

If -wallet=<path> is specified with a path that does not exist, it will now create a wallet directory at the specified location (containing a wallet.dat data file, a db.log file, and database/log.?????????? files) instead of just creating a data file at the path and storing log files in the parent directory. This should make backing up wallets more straightforward than before because the specified wallet path can just be directly archived without having to look in the parent directory for transaction log files.

For backwards compatibility, wallet paths that are names of existing data files in the -walletdir directory will continue to be accepted and interpreted the same as before.

Previously, wallets could only be loaded or created at startup, by specifying -wallet parameters on the command line or in the litecoin.conf file. It is now possible to load, create and unload wallets dynamically at runtime:

  • Existing wallets can be loaded by calling the loadwallet RPC. The wallet can be specified as file/directory basename (which must be located in the walletdir directory), or as an absolute path to a file/directory.
  • New wallets can be created (and loaded) by calling the createwallet RPC. The provided name must not match a wallet file in the walletdir directory or the name of a wallet that is currently loaded.
  • Loaded wallets can be unloaded by calling the unloadwallet RPC.

This feature is currently only available through the RPC interface.

Partial spend avoidance

When an address is paid multiple times the coins from those separate payments can be spent separately which hurts privacy due to linking otherwise separate addresses. A new -avoidpartialspends flag has been added (default=false). If enabled, the wallet will always spend existing UTXO to the same address together even if it results in higher fees. If someone were to send coins to an address after it was used, those coins will still be included in future coin selections.

The default minimum transaction fee -mintxfee has been lowered to 0.0001 LTC/kB after relaxing the minimum relay and dust relay fee rates in prior releases.

It is now possible for a single configuration file to set different options for different networks. This is done by using sections or by prefixing the option with the network, such as:

If the following options are not in a section, they will only apply to mainnet: addnode=, connect=, port=, bind=, rpcport=, rpcbind= and wallet=. The options to choose a network (regtest= and testnet=) must be specified outside of sections.

A new ‘label’ API has been introduced for the wallet. This is intended as a replacement for the deprecated ‘account’ API. The ‘account’ can continue to be used in V0.17 by starting litecoind with the ‘-deprecatedrpc=accounts’ argument, and will be fully removed in V0.18.

The label RPC methods mirror the account functionality, with the following functional differences:

  • Labels can be set on any address, not just receiving addresses. This functionality was previously only available through the GUI.
  • Labels can be deleted by reassigning all addresses using the setlabel RPC method.
  • There isn’t support for sending transactions from a label, or for determining which label a transaction was sent from.
  • Labels do not have a balance.

Here are the changes to RPC methods:

GIBX Swap: Sky is the Limit for the Best Decentralized Exchange Platform

The era of decentralized exchanges has come with the maturity and application of digital technologies.

Published

on

The value of GIBX Swap, which focuses on mainstream cryptocurrencies, is predicted to continue growing, shortly after its recent launch, and its price has the potential to reach record heights.

The first and leading decentralized exchange platform in the world has been launched on Sep.14,2021. Two days later, it is announced that GIBX Swap has started trading.

Meanwhile, due to its reputation, it has officially been listed on CoinMarketCap, the world’s most-referenced price-tracking website for cryptoassets in the rapidly growing cryptocurrency space. 

Decentralized tech and business

DeFi, shortened for Decentralized Finance, has been catching on since 2020. GIBX Swap holds the view that being decentralized is prerequisite to DEX. Traditional exchanges tend to be centralized.

On the one hand, it serves as information intermediaries, solving the issue of asymmetry of information to some extent; on the other hand, it create a new information asymmetry in favor of itself by the monopoly and manipulation of information, sometimes at the cost of the legitimate interests of clients.

No matter how the stock market performs, centralized exchanges can rely on charges and fees to guarantee their revenues.

As far as GIBX SWAP is concerned, the era of decentralized exchanges has come with the maturity and application of digital technologies. As a new type of exchange, the decentralized exchange makes the fullest use of the decentralization of blockchain, building peer-to-peer trust and transactions, with no intermediary.

The transaction links are all on the chain and performed directly by the open-source smart contract. As long as the user has and keeps the private key, he/she doesn’t have to worry about property security.

GIBX Swap features decentralized technologies with its brand-new block chain trading underlying platform, new generation of trading contract and cross-chain decentralized exchange, and complete business model with asset safety, market liquidity, trading fairness, ecological openness and transaction experience.

It aims to become the benchmark for DEX platforms and the leading DEX platform for token swaps.

GIBX Swap is an automated market maker (AMM) that allows a user to exchange two tokens. The liquidity provided to the exchange comes from Liquidity Providers (“LPs”) who stake their tokens in Liquidity Pools. In exchange, a user gets LP tokens that can also be staked to earn X tokens in the “Pool”.

Blockchain security protection from inside and outside

GIBX Swap puts emphasis on blockchain security protection. For one thing, it strengthens its own security from inside; for another thing, it has its smart contract technology code audited. Certik, the world’s leading block chain security audit institution has provided an audit for the project.

Established by the research team from Yale University and Columbia University with a decade of research, Certik has been providing code security audit services for blockchain applications and smart contracts, and the highest level of code security solution.

It is announced that GIBX Swap has passed the Certik security audit, which is carried out in a comprehensive review from Static Analysis, On-chain Monitoring, Social Sentiment, Governance & Autonomy, Market Volatility and Safety Assessment in search of potential safety hazards and possible production vulnerabilities.

It is confirmed once again after the audit by Certik that the technical code delivered by GIBX Swap is at a very high level of security, and GIBX Swap has the initiative to perform security tests.

Price predicted to reach new high 

GIBX Swap is highly committed to the supplier of true value, fairness, and innovation to decentralized finance through high-quality products and services.

It aims to become a benchmark for DEX platforms and take up the mantle of becoming the leading DEX platform on the market for token swaps. GIBX Swap is fast, secure no which anyone can swap and earn tokens.

A growing number of people has been paid attention to GIBX Swap ever since its launch. There have been over 46,000 followers in twitter, and more than 90,000 members in its TG.

GIBX Swap has shown strong potential lately and this could be a good chance to invest. Its value is expected to continue to expand, as shortage tends to encourage price rise.

In terms of price, GIBX Swap has an outstanding potential to reach new heights. X is forecast to increase in value. GIBX Swap can hit the highest price of $23.62 till 2030.

GIBX Swap is affiliated to GIBX, an international comprehensive Internet brokerage firm created by GIB Global Investment Bank & Capital Trust and a digital asset trading platform covering forex functions. GIBX has teamed up with world-renowned cryptocurrency platforms and top liquidity providers, including but not limited to: CoinMarketCap, CoinGecko, JPMorgan Chase, Goldman Sachs etc. in order to provide users a more transparent and convenient trading experience. As a financial trading platform regulated by international authorities such as FCA, ASIC, NFA, GIBX strictly follows all rules and regulations and uses reliable risk management solutions to ensure the safety of users’ capital.

Solana, Polkadot, Algorand: What is the Bitcoin effect on these altcoins

Published

on

With the market trading in red today pretty much all coins including Bitcoin and Ethereum are falling. However, there are some coins that made excellent gains in the last 2 months which are now facing huge price falls as well.

Which alts though?

Solana, Polkadot, and Algorand were three altcoins that successfully rallied between July and August. Polkadot rose from $12.34 all the way to $34.45 registering a 214.33% growth. Similar gains were observed for Algorand as the coin breached $2 and marked a 230.26% rise. 

The most gains were seen by Solana holders though mainly because the altcoin shot up 713.94%. An increase this high was the result of the NFT hype which took it up from $26.68 to $191.07

In fact, Solana and Algorand even registered new all-time highs during this time period. But each of these coins is now observing significant price falls as well. 

In the last 24 hours ALGO fell by 15.26%, DOT came down by 14.37% and SOL lost 16.8% of its price as of press time.

A huge reason behind this fall is also their exhausted momentum since even after the September 7 fall, DOT and ALGO witnessed another price rise before they finally hit a slowdown.

Owing to this investors are possibly getting rid of their holdings in both spot and derivatives markets. Sell volumes at the time of this report have increased and liquidations rose to millions for all 3 altcoins. Since SOL gained the most, it lost the most as well and its liquidations touched $25 million.

Can Bitcoin save them?

Well since Bitcoin’s price movement commands the market’s movement it is obvious that BTC needs to reduce losses first. But more importantly, these assets’ correlation to Bitcoin will determine how much they will be affected by BTC. Right now Algorand is at the lowest at 0.57, followed by Solana at 0.7, and at the highest is Polkadot (0.88)

However, surprisingly, investors are most positive about Algorand of all three hoping for a recovery soon.

Once Bitcoin and Ethereum change their movement, other coins would follow suit. And that’s when some recovery can be expected.

Trading Volume by Asset


The figures below break down the trading volume of the largest, mid-size, and smallest assets. Cryptos are in purple, fiats are in blue. For each asset, the chart contains the daily trading volume in USD, and the percentage of the total trading volume. The percentages for fiats and cryptos are treated separately, so that they both add up to 100%.
