    Solidity

    Solidity

    The Smart Contract Programming Language

    Solidity is a statically-typed curly-braces programming language designed for developing smart contracts that run on Ethereum. Solidity 0.8.4 adds custom structured errors, allows more flexible configuration of the SMTChecker and fixes a bug in the Solidity ABI decoder v2. Read more about the bug here. With v0.8.4, errors can be defined inside and outside of contracts (including interfaces and libraries). This provides a convenient and gas-efficient way to explain to users why an operation failed. As a relatively young language, Solidity is advancing at a rapid speed. We aim for a regular (non-breaking) release every 2-3 weeks, with approximately two breaking releases per year. You can follow the implementation status of new features in the Solidity Github project. You can see the upcoming changes for the next breaking release by switching from the default branch (develop) to the breaking branch.

    LBRYcrd

    LBRYcrd

    The blockchain that provides the digital content namespace for LBRY

    LBRYcrd uses a blockchain similar to bitcoin to implement an index and payment system for content on the LBRY network. It is a fork of the bitcoin core. In addition to the libraries used by bitcoin, LBRYcrd also uses icu4c. What if anyone in the world could publish digital content, anyone else in the world could access it (for free or for payment), and that entire system worked without any centralized authority or point of control? LBRY uses a public, proof-of-work blockchain that is very similar to Bitcoin. The blockchain is the foundation of the protocol stack. The most salient feature of the LBRY blockchain is the association of a normalized string of characters (a “name”) with a structured set of metadata. This coupling is called a claim. The LBRY blockchain stores names and metadata in a parallel Merkle tree, separate from the tree used to store transaction data. This allows LBRY URLs to be trustfully resolved even without a full copy of the blockchain.

    Krypto-trading-bot

    Krypto-trading-bot

    Self-hosted crypto trading bot, automated high frequency market

    K is a family of (very customizable) very low latency market-making trading bots with a fully featured web interface. It can place and cancel orders on one of the several compatible exchanges in less than a few milliseconds per order on a decent machine. If you don't want to configure or hardcode your own trading strategies in your own machine, you can run strategies from someone else at kryll.io (or at any other trading community out there). Our bots run on unix-like systems. Persistence is achieved through a built-in server-less SQLite C++ interface. Data transfers are directly done from your machine to the exchange using the latest CURL and OpenSSL versions. Installation in a dedicated Debian, Raspberry, Red Hat, CentOS or macOS instance without Docker is recommended. The web UI is compatible with most web browsers/resolutions, but Brave or Firefox at 1600px are recommended. Doesn't require configuration of any web server (unless installed behind your own reverse proxy).

    Zcash

    Zcash

    A privacy-protecting, digital currency built on strong science

    Zcash is the future of money-- digital, decentralized and private. It is an implementation of the "Zerocash" protocol; a digital currency based on Bitcoin's code, but with a higher standard of privacy. Like Bitcoin, Zcash transaction data is posted to a public blockchain. However unlike Bitcoin, your personal and transaction data stay completely private. Thanks to a sophisticated zero-knowledge proving scheme, transactions can be verified without showing any information at all about the sender, receiver or transaction amount. Selective disclosure features are available for users who may need these for compliance or audit purposes. Zcash was built by top cryptographers, with an underlying protocol based on the research of scientists from MIT, Technion, Johns Hopkins, Tel Aviv University and UC Berkeley.

    SuperEnalotto

    Combina statistiche classiche con metodi di entaglement quantistico

    SUPER ENALOTTO QUANTISTICO. La password è string18, tutto minuscolo. Negli ultimi otto mesi ho realizzato un programma che si basa in parte sulle informazioni di entanglement quantistico per alzare di molto le probabilità di vittoria al super-enalotto. In questo ambito il programma elabora centinaia di migliaia di serie casuali per ricercare la serie piu prossima allo storico reale e poi su questa esegue le sue previsioni. Il programma elabora anche tre giocate secondo le statistiche classiche determinando i migliori numeri in funzione di frequenze di uscita e ritardo ed escludendo quelli fuori dal range con la regola dei tre sigma (dev.std.). È intuitivo e facile da usare, ho scritto il codice partendo da zero incluse le routine di input e del controllo del mouse, così non dipende da copyright, librerie o frameworks e può essere usato liberamente anche in sistemi non windows. Non son un giocatore ma un matematico, ho testato il programma e in molti

    Monero

    Monero

    Secure, Private Digital Currency

    Monero is a secure, private, untraceable cryptocurrency. It is decentralized-- dependent on a distributed peer-to-peer consensus network where every transaction is cryptographically secured. With Monero you are your own bank, you control your funds and can spend safely. No one else can see your balances, track your transfers or any other transactions unless you allow them to. Monero uses ring signatures, ring confidential transactions, and stealth addresses making it absolutely private and untraceable. No transactions can ever be linked to a particular user or real-world identity. And because it is private by default, it is fungible or mutually interchangeable, and cannot be blacklisted due to their association with previous transactions.
