How do you keep your digital currency safe? Jerry Brito, Executive Director of the Coin Center, explains how multisignature technology provides increased security for digital currencies such as Bitcoin. As always, the Federalist Society takes no position on particular legal or public policy issues; all expressions of opinion are those of the speaker.

How to create and use Multi Sig Bitcoin Wallets
 
10:23
This is useful if you want more than one person to be required to 'sign off' or 'authorize' any outgoing Bitcoin wallet transaction. This is also a great security measure for your own personal wallets, as you could store each wallet separately. In this video we are using Electrum so the process would be identical for Litecoin as well. You can subscribe to our youtube channel here, we also have a telegram channel we chat and communicate through: Hodl Hodl Exchange: https://hodlhodl.com Hodl Hodl Exchange TESTNET: https://testnet.hodlhodl.com/ Follow us on Twitter: https://twitter.com/hodlhodl Join our Telegram chat: https://t.me/HodlHodl Read our Blog: https://medium.com/@hodlhodl Email: [email protected]

Bitcoin Q&A: Multi-signature and distributed storage
 
17:58
What happens when wallets (personal or at an exchange) are hacked? What is "sweeping" with regards to private keys? After a hack, is it possible to track the stolen bitcoin and identify the hacker? How do you keep bitcoin safe in a group / corporate environment? Is it possible to create a multi-signature setup with Trezor and Electrum? Could passphrases be brute-forced? What is happening with browser extension deprecation? You will have to evaluate which tools are the best based on the amount of cryptocurrency you own, your circumstances, and your threat model.

Bitcoin 101 - Multi-Signature Addresses pt1 - Coding This Major Security Improvement
 
21:45
Just like the Wright brothers, on those first flights at Kitty Hawk, didn't concern themselves that much with landing. And improvements like anti-lock brakes and seat belts help protect passengers in cars. Bitcoin is now in that 'second phase' where security is becoming massively important. Fortunately, because the currency is programmable, anything is really possible. Originally introduced into the bitcoin client a few years ago, multisignature addresses massively more secure than regular ones. Their adoption by all wallet manufacturers is coming. But, for you techies and voyeurs, we'll jump inside the ideas of multi-sig and even program the stuff. Hope you enjoy. All the public and private keys are at the bottom of this description James' code can be found here: https://github.com/wobine/blackboard101 there, you'll see the code for part one and two of this video Jeff Garzik's Bitcoin python library is here https://github.com/jgarzik/python-bitcoinrpc remember to replace his connection.py file with ours for multisigs And a little bit about bitcoind is here https://en.bitcoin.it/wiki/Bitcoind but remember that it really is the most bare-bones bitcoin wallet software, but the one which allows the most programming. we love it. A multisig wallet is already in production: Check it out https://www.bitgo.com/ We're still waiting to see how they use multisig to see if it really works for the end user. And finally, here's our lovely multisig address http://live.bitcore.io/address/35Z3xG92YkW5Xo4ngQw6w5b3Ce6MDw94A8 So cool to see it live and in action.

Advanced Bitcoin Scripting -- Part 1: Transactions & Multisig
 
59:58
This is the first part of a more technical talk where Andreas explores Bitcoin script, with examples from the 2nd edition of Mastering Bitcoin, focusing on the use of conditional statements, flow control, guard clauses and time locks. The examples will include advanced multi-signature scripts, hash time lock contracts and asymmetric revocable commitments. Then he answers questions about Bitcoin's quirky bugs, where Bitcoin differs from Ethereum at a scripting level, how SegWit works, how consensus rules change, and whether Bitcoin is more than just a currency.

Биткоин кошелек с мультиподписью | Electrum Multi-Signature Wallet
 
09:30
Что такое биткоин кошелек с мультиподписью? Как создать биткоин кошелек с мультиподписью в Electrum. Multi-signature биткоин кошелек - это кошелек, для отправки средств с которого требуются подписи с нескольких приватных ключей. Например, можно создать общий биткоин кошелек с 3 участниками, у каждого из которых будет по одному приватному ключу. Для совершения транзакций с этого кошелька, будет достаточно двух подписей. То есть, два участника смогут спокойно снять средства с адреса, так как они вместе подпишут транзакцию. Кошельки с мультиподписью используются для обеспечения лучшей безопасности средств. ☑️Наш канал в Telegram: https://t-do.ru/crypt0inside ☑️Самый безопасный кошелек Trezor - https://goo.gl/KBUAvQ ☑️Поддержать автора(Bitcoin): https://tallyco.in/Crypt0_Inside/ ☑️Поддержать автора(Фиат): https://yasobe.ru/na/cryptoinside Вы находитесь на канале CryptoInside.

EB53 – Arianna Simpson: Security and Usability with BitGo's Multi-Signature HD Wallets
 
01:02:30
Support the show, consider donating: 3ESkdAFgxLez6VEo6AfxJVNPi475mdk5WS (http://bit.ly/1AH9WR1) Keeping Bitcoins safe from theft is probably one of the things Bitcoin holders worry the most about. Historically, there have been a number of recommended best practices like paper wallets, BIP 38 wallet cards and cold storage. Although these remain relatively safe ways to store Bitcoins, implementing these solutions can be complicated and difficult to manage for day-to-day transactions. Recently, some companies have begun introducing multi-signature HD wallet services, where 2-out-of-3 signatures are required to sign transactions. These solutions offer security and usability, with the assurance that Bitcoins will remain safe, and the ability to transact with ease. In fact, the website P2SH.info tracks the adoption of multi-sig, and it has been growing exponentially in recent months. Which brings us to our guest: Arianna Simpson, an Account Specialist at BitGo, a company that provides a simple multi-signature HD wallet solution for individuals and businesses. We talked to Arianna about BitGo and the services they offer, discuss different use cases for multi-sig HD wallets and make projections about the evolution of the wallet space from different angles.

Bitcoin M-of-N Multisig Addresses - Well Tempered Hacker
 
20:40
Standard bitcoin transactions involve payment to an address which requires a signature from one private key to spend. With multi-signature addresses, M of N transactions are possible. In this episode we will create a multi-signature address which requires two of three signatures to spend. This could be useful for securing bitcoin in multiple locations reducing the "all or nothing" risk of loosing a private key. One example use of this is in securing some amount of bitcoin offline. You might first generate three private keys and from them generate a 2 of 3 multisig address. At this point, the address is worthless. Then you might print out those private keys and the redeem script onto three separate pieces of paper and destroy any digital copy. Next you might send two of those pieces of paper to two different friends of yours and keep the third in a safe place yourself. Remember, there is no value on the multisig address yet so if they get lost in transit or for some reason you believe the papers didn't make it to their destinations safely, you just start over. With our keys safely in three separate locations, you might transfer some bitcoin to the multisig address, loading up your offline wallet. Some time goes by and you might want to gain access to your bitcoin. You create a spend transaction sending the value to some other online wallet. This transaction isn't valid yet because nobody has signed it so it is safe to send via email to one of your friends. They pull out the piece of paper you sent them, type in the private key adding their signature to the transaction. The transaction is still not yet valid so they email it back to you without worry. You then might decide to add your signature to the transaction making it valid. Again, the transaction would be safe to email because any attempt to change the transaction redirecting it to some other address would invalidate the whole thing. After deciding this is still what you wanted, you might decide to transmit this previously completely offline transaction on the network which would spend the funds away from the multisig address. This is very similar to how many online wallet provider's "vault" features work. However, doing this yourself removes the requirement to trust a possibly disinterested third party. As with anything you do yourself, however, there wouldn't be a third party to blame if you messed things up. (I'm not responsible for any bitcoin you loose trying to get this working!) There are risks in either strategy. The software used in this demo is available here: https://github.com/anders94/bitcoin-2-of-3-multisig

A 3-of-5 Multisig Wallet with Copay
 
04:09
Copay is a multisignature wallet being developed by BitPay's bitcore team. Copay has a number of innovative features that make it unlike any other wallet: * It is inherently multisignature, meaning more than one person (or device) must sign outbound transactions. This makes it next to impossible for someone to steal funds from the wallet. If one person has their private keys stolen, the funds are still safe. * It is decentralized and does not rely on centralized servers. There is a small dependence on two servers (PeerJS and Insight), both of which can be run yourself. The wallet files are stored locally in HTML5 local storage, and communication is p2p using WebRTC. * The wallet uses BIP32, which, in a nutshell, means it's really easy to back up your wallet. Back it up once, and it's backed up forever. * It is 100% open-source, both client-side and server-side. We encourage outside contributors in every aspect Copay, as well as with our other projects, Bitcore and Insight. The source code is available here: https://github.com/bitpay/copay The transaction created in the video can be seen here: http://test.insight.is/tx/10a7c5fa0eccb075fc7dc38b146b07b980a3dc95794878db3a7151571922fcdf

Waves Smart Contracts: Multisignature Example
 
35:45
In this tutorial, the use case supposes that there are 3 people in a team and they hold common funds for corporate purposes. It is convenient for the team to make a decision about the allocation of common funds according to the majority decision, and they use a multi-signature account to do this (smart account). They create an account and do SetScriptTransaction with the multisig account. The idea here of a smart account is the following: before the transaction is submitted for inclusion in the next block, the account checks if the transaction meets certain requirements, defined in a script. The script is attached to the account so the account can validate every transaction before confirming it.

Bitcoin Q&A: Key management and inheritance planning
 
20:12
How does the average person solve the "$5 wrench problem" / prevent rubber-hose cryptanalysis? What is the easiest way to do a multi-signature or multi-factor set-up? Could timelocks and smart contract solutions be used for inheritance issues? The technology and educational resources around key management need to mature first. There needs to be a pragmatic balance between legal and technical plans, with human-based processes and controls. Take an entrepreneurial perspective and you will help overcome the barriers to adoption!

Batch Verification, Signature and Optimization of Schnorr BIP ~ bitcoin-dev Mailinglist
 
31:12
Here are two BIP drafts that specify a proposal for a Taproot softfork. A number of ideas are included: * Taproot to make all outputs and cooperative spends indistinguishable from eachother. * Merkle branches to hide the unexecuted branches in scripts. * Schnorr signatures enable wallet software to use key aggregation/thresholds within one input. * Improvements to the signature hashing algorithm (including signing all input amounts). * Replacing OP_CHECKMULTISIG(VERIFY) with OP_CHECKSIGADD, to support batch validation. * Tagged hashing for domain separation (avoiding issues like CVE-2012-2459 in Merkle trees). * Extensibility through leaf versions, OP_SUCCESS opcodes, and upgradable pubkey types. The BIP drafts can be found here: * https://github.com/sipa/bips/blob/bip-schnorr/bip-taproot.mediawiki specifies the transaction input spending rules. * https://github.com/sipa/bips/blob/bip-schnorr/bip-tapscript.mediawiki specifies the changes to Script inside such spends. * https://github.com/sipa/bips/blob/bip-schnorr/bip-schnorr.mediawiki is the Schnorr signature proposal that was discussed earlier on this list (See https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2018-July/016203.html) https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2019-May/016914.html https://twitter.com/pwuille If you have learned something valuable, donate a couple sats to Max as a thank you note: 3Fe6dcwhkLnMo7c2FrkYduR5xJgo38dTTS https://tallyco.in/HillebrandMax Support the show by buying bitcoin on https://hodlhodl.com/join/ERCT Listen to WCN Audio Podcasts: https://itunes.apple.com/us/podcast/the-world-crypto-network-podcast/id825708806 Check out the brand new http://WorldCryptoNetwork.com/ Find out more about Max https://towardsliberty.com Follow WCN on Twitter: https://twitter.com/WorldCryptoNet Follow Max on Twitter: https://twitter.com/HillebrandMax Contribute to Max’s Bachelor Thesis on Multi Signature in the Lightning Network: https://towardsliberty.com/multisig https://www.youtube.com/playlist?list=PLPj3KCksGbSaBmpAmdp_icu2PkywjeUI6 Bitcoin to the Max: https://youtube.com/playlist?list=PLPj3KCksGbSZtGhC7nIr_Mf1oCeP8U1tV Bitcoin Only: https://www.youtube.com/playlist?list=PLPj3KCksGbSYX2cNoOaV-w-9QuZ62LDk_ Read Rothbard ~ Use Bitcoin: https://youtube.com/playlist?list=PLPj3KCksGbSafpOorg0NdeVXGIPNqV_8a Open Source Everything: https://youtube.com/playlist?list=PLPj3KCksGbSb1h33FZbsrtr1feIIwTBHt Breaking Bitcoin 2019: Hackers Congress Paralelni Polis 2018: https://youtube.com/playlist?list=PLPj3KCksGbSY8xt-x-KoDb6L380odP_qu Baltic Honeybadger 2018: https://youtube.com/playlist?list=PLPj3KCksGbSZsgH48ZDxNdzRXbg_pvMnz Understanding Bitcoin 2019: https://www.youtube.com/playlist?list=PLPj3KCksGbSYnUncEaz5SM0ihfjPtGTvO Bitcoin-Dev Mailing List: https://www.youtube.com/playlist?list=PLPj3KCksGbSZWpXUZAp2y0ftJsjXPWdtO Schnorr: https://www.youtube.com/playlist?list=PLPj3KCksGbSbUYnzXthFazpUw6ZJCUKOu Nodl Personal Bitcoin Assistant: https://www.youtube.com/playlist?list=PLPj3KCksGbSYvbhhUpIehNqnXFLkz1AD1 Bisq Decentralized Exchange: https://youtube.com/playlist?list=PLPj3KCksGbSZR33X7kJmDMwIEH-wrrpCJ ColdCard Wallet: https://youtube.com/playlist?list=PLPj3KCksGbSZJzC4besvtu8CSroBosrdt GPG + Yubikey: https://www.youtube.com/playlist?list=PLPj3KCksGbSZkVpgAZjAFfFp4D0SHLnFw Purism: https://youtube.com/playlist?list=PLPj3KCksGbSZm6k6GlJRhY6T7wSvoEWbG Bitcoin Op Tech Newsletter: https://youtube.com/playlist?list=PLPj3KCksGbSY9pV6EI5zkHcut5UTCs1cp The Ethics of Money Production: https://www.youtube.com/playlist?list=PLPj3KCksGbSZFi81lduijpsmkhxQv2Gm8 What Has Government Done to Our Money?

EVERYTHING about Schnorr Signatures ~ Jonas Nick ~ Understanding Bitcoin
 
01:10:52
Jonas and Max cover EVERYTHING you need to know about the incredible potential of Schnorr signatures! - Key aggregation for efficient MuSig, - Signature aggregation for cheaper coin joins, - Taproot and Graftroot for infinite scripts hidden in keys, - Scriptless scripts for atomic and coin swaps for enhanced privacy, - indistinguishable lightning opening transactions, - and the nuances of the cryptography! Understanding Bitcoin conference is organized with a focus on the non-technical, non-developer users that want to increase their knowledge and technical participation in the Bitcoin network. Not everyone has the skills to take full advantage of what Bitcoin has to offer, so this event will help the average user be more familiar with best practices and understanding all aspects of interacting with the Bitcoin network. There will be practical hands on presentations of how to set up features, along with theoretical discussions removing the FUD and misconceptions surrounding the current state of Bitcoin’s Trustless Network. https://understandingbtc.com/ If you have learned something valuable, donate a couple sats to Max as a thank you note: 3DqEnU6dW6bZesrVdThrrQjQKgN7dpY5vv https://tallyco.in/HillebrandMax Support the show by buying bitcoin on https://hodlhodl.com/join/ERCT Listen to WCN Audio Podcasts: https://itunes.apple.com/us/podcast/the-world-crypto-network-podcast/id825708806 Check out the brand new http://WorldCryptoNetwork.com/ Find out more about Max https://towardsliberty.com Follow WCN on Twitter: https://twitter.com/WorldCryptoNet Follow Max on Twitter: https://twitter.com/HillebrandMax Follow Jonas on Twitter: https://twitter.com/n1ckler Contribute to Max’s Bachelor Thesis on Multi Signature in the Lightning Network: https://towardsliberty.com/multisig https://www.youtube.com/playlist?list=PLPj3KCksGbSaBmpAmdp_icu2PkywjeUI6 Bitcoin to the Max: https://youtube.com/playlist?list=PLPj3KCksGbSZtGhC7nIr_Mf1oCeP8U1tV Bitcoin Only: https://www.youtube.com/playlist?list=PLPj3KCksGbSYX2cNoOaV-w-9QuZ62LDk_ Read Rothbard ~ Use Bitcoin: https://youtube.com/playlist?list=PLPj3KCksGbSafpOorg0NdeVXGIPNqV_8a Open Source Everything: https://youtube.com/playlist?list=PLPj3KCksGbSb1h33FZbsrtr1feIIwTBHt Hackers Congress Paralelni Polis 2018: https://youtube.com/playlist?list=PLPj3KCksGbSY8xt-x-KoDb6L380odP_qu Baltic Honeybadger 2018: https://youtube.com/playlist?list=PLPj3KCksGbSZsgH48ZDxNdzRXbg_pvMnz Bitcoin-Dev Mailing List: https://www.youtube.com/playlist?list=PLPj3KCksGbSZWpXUZAp2y0ftJsjXPWdtO Nodl Personal Bitcoin Assistant: https://www.youtube.com/playlist?list=PLPj3KCksGbSYvbhhUpIehNqnXFLkz1AD1 Bisq Decentralized Exchange: https://youtube.com/playlist?list=PLPj3KCksGbSZR33X7kJmDMwIEH-wrrpCJ ColdCard Wallet: https://youtube.com/playlist?list=PLPj3KCksGbSZJzC4besvtu8CSroBosrdt GPG + Yubikey: https://www.youtube.com/playlist?list=PLPj3KCksGbSZkVpgAZjAFfFp4D0SHLnFw Purism: https://youtube.com/playlist?list=PLPj3KCksGbSZm6k6GlJRhY6T7wSvoEWbG Bitcoin Op Tech Newsletter: https://youtube.com/playlist?list=PLPj3KCksGbSY9pV6EI5zkHcut5UTCs1cp The Ethics of Money Production: https://www.youtube.com/playlist?list=PLPj3KCksGbSZFi81lduijpsmkhxQv2Gm8 What Has Government Done to Our Money?

Bitcoin backed banks will solve these problems. They can work like banks did before nationalization of currency. Different banks can have different policies, some more aggressive, some more conservative. Some would be fractional reserve while others may be 100% Bitcoin backed. Interest rates may vary. Cash from some banks may trade at a discount to that from others.

Use a Multisig Wallet to Protect your Bitcoin Transactions
 
03:27
As Bitcoin and other cryptocurrencies gain popularity as a mode of payment transfer, it has become common for the average Bitcoin user to be scammed by an anonymous identity who requests payment for some work is then never heard from again. . The decentralized nature of cryptos certainly has a tradeoff – unlike a credit card or bank transaction that can be reverted, a cryptocurrency transfer once confirmed is permanently recorded on the Blockchain. This is where multi-signature (multisig) wallets come to our rescue.. A multisig wallet is a special bitcoin wallet that requires more than one private key to sign transactions. Most multi-signature setups usually involve three parties – the sender of the payment, the recipient, and an escrow agent. Each of the three parties holds one private key, and to send any transaction, at least two private keys must be used.. Typically, escrow agents are trusted members of the Bitcoin community or registered entities who arbitrate any disputes that may arise. Therefore, the buyer is protected in case the seller turns out to be fraudulent, and the seller, too, is assured of payment even if the buyer refuses to pay.. CREATING A MULTISIG WALLET. There are many ways to create a multisig wallet. In fact, most Bitcoin clients support the multisig protocol. Electrum and Armoury are used by many crypto holders because they have provisions for advanced settings like custom fees etc. which are great for power users. . BitGo is another popular option for those who prefer a web-based client. In my opinion, however, CoPay offers the most streamlined, easy to use interface, that is usable by anyone, even a new Bitcoin user. So for the purposes of this tutorial, I will be using. Step 1: Download CoPay. Head over to the CoPay website and download the appropriate installer for your platform. A great advantage of using CoPay is its support for nearly all desktop and mobile platforms (iOS and Android included).. Step 2: Start by setting up your personal wallet. Open the installed app, and run through the quick setup to create your personal wallet. This will involve typing in an email address for transaction notifications, and noting down a mnemonic phrase that can be used as a backup in case CoPay is accidentally deleted from your computer.. Step 3: Create a Shared Wallet. Multisig wallets are called ‘Shared Wallets’ in CoPay. Once your personal wallet is set up, click on the shared wallet option on the CoPay home screen to create a multisig wallet. You will be presented with a screen where you can configure the wallet with the number of co-payers, the number of signatures required etc. depending on your needs.. Step 4: Share the CoPay invite with others. The last step is to share your multisig wallet with the 2 other parties. Send them the CoPay code displayed or ask them to scan the QR code. That’s it! Your CoPay escrow is set up! Now everytime someone requests a payment, you will receive a notification to confirm the transactio
