euBRASIL, construindo a Bit(*)moeda no Brasil.
✔ O que é o Dinheiro ?
O dinheiro é um valor qualquer baseado numa condição de escassez a nível matemático.
Número Primo
Algoritmo de Assinatura Digital de Curvas Elípticas (Elliptic Curve Digital Signature Algorithm) ECDSA,
que gera o desafio computacional a nível matemático.
Chave de 256 bits
Utilizando a Base16 (Hexadecimal) SHA256 gera através diversas operações aritméticas com bits uma chave que sempre terá 256 bits.
Espelhamento.( x-, y+ )
Dentro de um Plano Cartesiano (LinhaX e LinhaY) as coordenadas são refletidas de cima para baixo e vice-versa de acordo com ( y² = x³ + 7 ) gerando as coordenadas de uma Chave Pública "gigantesca".
Cryptografia
Operação Aritmética de adição, subtração, multiplicação com números primos gigantescos na ordem de 32 bytes, construindo índices matemáticos complexos de 64 casas hexadecimais dentro de um Universo de possibilidades.
Frase Mnemônica
Através de um consenso denominado BIP39, foram construídas 2.048 palavras inglês e outros idiomas BIP39. Toda chave privada que gera a chave pública,
pode ser interpretada através de 12 palavras ou mais.
New Address create a new address
Any keys used you will need to manually store safely as they will be needed later to redeem the bitcoins.
Address Options
You can use the advanced options below to generate different kind of keys and addresses.
New SegWit Address Smaller & Faster Transactions
Any keys used you will need to manually store safely as they will be needed later to redeem the bitcoins.
Address Options
You can use the advanced options below to generate different kind of keys and addresses.
New Multisig Address Secure multisig address
Public keys can be generated in your browser or from your bitcoin client.
Enter the public keys of all the participants, to create a multi signature address. Maximum of 15 allowed. Compressed and uncompressed public keys are accepted.
Enter the amount of signatures required to release the coins
New Time Locked Address Coins can be released only after a certain date
Use OP_CHECKLOCKTIMEVERIFY (OP_HODL) to create a time locked address where the funds are unspendable until a set date and time has passed.
Public keys can be generated in your browser or from your bitcoin client.
Enter the public key that will be able to unlock the funds after the a certain date.
Enter the or required to release the coins:
New HD Address making bip32 even easier
Use the form below to generate a master hierarchical deterministic address.
Address Options
You can use the advanced options below to generate different kinds of master addresses.
Transaction Create a new transaction

Address, WIF key, Redeem Script or Transaction ID:Bitcoin Fee Calculator
This page will give you a guide on the lowest fee to use to get your transaction included within the next few blocks. It works by predicting the size of a transaction and comparing it to another transaction in a recent block to determine an appropriate fee.
Recommended Fee: 0.00000000 BTC
for a transaction of 0 bytes

What is Bitcoin?
Bitcoin is a type of digital currency in which encryption techniques are used to regulate the generation of units of currency and verify the transfer of funds, operating independently of a central bank. See weusecoins.com for more information.
Information
Coinb.in is a free and open source project released under the MIT license, originally by OutCast3k in 2013. Discussion of the project can be found at bitcointalk.org during its early testing stages when its primary focus was to develop a proof of concept multisig solution in javascript.
Coinb.in is run and funded by the generosity of others in terms of development and hosting.
Coinb.in is kindly hosted by BitVPS.com.
Privacy
Coinb.in believes strongly in privacy, not only do we support the use of TOR, the site does not collect and store IP or transaction data via our servers nor do we store your bitcoins private key. We do route traffic via cloudflare using an SSL certificate.
Support
We recommend that you first check our service status page and then blog page which has multiple guides. However if the problem persists you can contact us by emailing support{at}coinb.in.
