En cryptographie, un nonce est un nombre aléatoire, destiné à être utilisé une seule fois, qui est ajouté à une suite de caractères immuable pour trouver une nouvelle empreinte (hash) lors du passage par un logiciel de chiffrement. Comme la longue suite de caractères formée par un bloc est bien immuable, les mineurs n’ont d’autre choix que d’essayer des milliards de nonces pour chaque bloc, jusqu’à trouver celui qui permette d’aboutir à un hash satisfaisant le niveau de difficulté du moment pour que son bloc soit accepté par le réseau.
We're delighted to welcome StraitsX to the Polygon ecosystem and recognize the immense utility they'll bring -- particularly within Polygon's expanding DeFi ecosystem. We look forward to providing the infrastructure that allows the project to flourish in the coming months and years." Hamzah Khan, Head of DeFi and Labs at Polygon, said: "StraitsX's stablecoins are some of the most-utilized in the cryptocurrency
space, particularly outside the U.S.
Doing this has invalidated transactions made using this function from the earliest days of Bitcoin (transactions that could well be relevant to Satoshi’s and other early Bitcoiners’ coins, which is a whole other issue). The NLockTime function already existed on Bitcoin before then, but has been "broken" with other timed-transaction procedures added or removed.
Bitcoin mining, as per some estimates, consumes the same amount of electricity as whole countries. This is one of the reasons why many crypto experts and influencers are pushing for Bitcoin to change from Proof of Work consensus to Proof of State consensus mechanism.
Add: The [wallets_withdraw] shortcode can now scan addresses from QR code in devices that support it. Use theme templates instead to provide your custom markup. Add: The border radius of UIs (corner roundness) can now be controlled in Customizer. A template loader can load markup for these UIs from a theme or child theme, falling back to the plugin’s templates if needed. Improve: The UIs are now more easily overridable by themes. Change: The wallets_views_dir attribute and filter are removed. Add: The colors used in [wallets_transactions] shortcodes to signify transaction status can now be changed in Customizer. Add: Admin dashboard widget now shows multiple tabs with statistics on recent transactions. Improve: cryptocurrency All operations that modify transaction data now also refresh the time on the updated_time column. Add: When the plugin is network-active across a multisite install, the admin transactions list shows extra column Site . Transactions are now logged with clearer information, including links to user profiles and block explorers. Improve: The cold storage admin screens now also display the amount of funds locked in unaccepted & pending transactions. Improve: For Bitcoin-like adapters, the RPC secret is not shown in the markup, but bullets are shown instead. Add: The [wallets_api_key] shortcode can now be used as a widget.

Improve: When creating database tables for the first time, the WordPress default is used for character collation and encoding. Fix: Adapters for fiat coins are no longer shown in the cold storage section, as these adapters are not backed by wallets. Helps determine exchange rates in low liquidity markets. Fix: When Bittrex is used as an Exchange Rates provider, if the last price is not available, the plugin falls back to using the average of the Bid/Ask values, or one of the two values if only one is available. Useful for testing using testnet. Add: The opacity of UIs while loading data over AJAX can now be controlled in Customizer. Improve: In the [wallets_balance template="list"] UI, the text "Show zero balances" is clickable and toggles the checkbox. Improve: In the debug tab of the admin dashboard, memory values are now shown with thousand separators and units (bytes) for easier visual inspection. Improve: The plugin will now warn the user in the frontend if HTML comments have been minified, as this is a common pitfall for new users. Change: Tradesatoshi is removed from list of Exchange Rate providers as the service is shut down. This is a fail-safe mechanism that detects transactions that would otherwise slip through undetected if curl calls from walletnotify were to fail for any reason.
