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. -

Bitcoin
Bitcoin Core integration/staging tree
Bitcoin Core connects to the Bitcoin peer-to-peer network to download and fully validate blocks and transactions. It also includes a wallet and graphical user interface, which can be optionally built. Bitcoin Core requires a one-time download of about 400GB of data plus a further 5-10GB per month. By default, you will need to store all of that data, but if you enable pruning, you can store as little as 6GB total without sacrificing any security. For more information about setting up Bitcoin Core, please read the full node guide. Download verification is optional but highly recommended. Performing the verification steps here ensures that you have not downloaded an unexpected or tampered version of Bitcoin, which may result in loss of funds. Experienced users who don't mind performing additional steps can take advantage of Bitcoin Core's reproducible builds and the signed checksums generated by contributors who perform those builds. -

Qtum
Qtum Core Wallet
Qtum is a decentralized blockchain project built on Bitcoin's UTXO model, with support for Ethereum Virtual Machine-based smart contracts, and secured by a proof of stake consensus model. It achieves this through the revolutionary Account Abstraction Layer which allows the EVM to communicate with Qtum's Bitcoin-like UTXO blockchain. Welcome to the Qtum Ignition Main Network. This is the main network where the tokens hold value and should be guarded very carefully. If you are testing the network or developing unstable software on Qtum, we highly recommend using either testnet or regtest mode. A Proof of Stake consensus system which is optimized for Qtum's contract model. Any user can stake and help to secure the network. There is no voting, master nodes, or minimum amount required. There have been transactions as small as 2 Qtum that have created blocks in the past. Staking from smart contracts is under development. -

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
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. -

Trust Wallet Core
Cross-platform, cross-blockchain wallet library
Trust Wallet Core is an open source, cross-platform, mobile-focused library implementing low-level cryptographic wallet functionality for a high number of blockchains. It is a core part of the popular Trust Wallet, and some other projects. Most of the code is C++ with a set of strict C interfaces, and idiomatic interfaces for supported languages: Swift for iOS and Java for Android. Wallet Core supports more than 50 blockchains, Bitcoin, Ethereum, Binance Chain, and most major blockchain platforms. For new coins, you need to implement address handling and signing functionality in the wallet-core. For new coins on already supported blockchains or variations of already supported blockchains, please consider proper reuse of existing implementation. The Trust Wallet development team is always striving to add more blockchains that will be essential for developers and wallet users. We choose blockchains carefully based on the impact they will have for our community. -

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 -

BlockSci
A high-performance tool for blockchain science and exploration
The Bitcoin blockchain, currently 280 GB and growing, contains a massive amount of data that can give us insights into the Bitcoin ecosystem, including how users, businesses, and miners operate. BlockSci enables fast and expressive analysis of Bitcoin’s and many other blockchains. Current tools for blockchain analysis depend on general-purpose databases that provide "ACID" guarantees. But that’s unnecessary for blockchain analysis where the data structures are append-only. We take advantage of this observation in the design of our custom in-memory blockchain database as well as an analysis library. BlockSci’s core infrastructure is written in C++ and optimized for speed. (For example, traversing every transaction input and output on the Bitcoin blockchain takes only 1 second on our r5.4xlarge EC2 machine.) To make analysis more convenient, we provide Python bindings and a Jupyter notebook interface. -
