Voyager had reportedly lent 3AC US$350 million in USDC and 15,250 Bitcoin, all up totalling more than US$673 million. • Crypto brokerage Voyager Digital is no longer playing softball regarding its hefty loan to the VC hedge fund Three Arrows Capital (3AC). It’s now issued 3AC with a default notice in an attempt to recover its funds.
The respected on-chain crypto
analytics firm released a report titled ‘A Bear of Historic Proportions‘ on the weekend, crypto breaking down several broken-down metrics related to the latest blockchain-investment mauling.
No programming experience required, but it will be helpful for some of the exercises. Anyone with a slight technical background can benefit from this course. Our goal is to provide educational material (and the correct mental model) to allow bystanders to join the cryptocurrency community.
A user is still able to run only the sidechain-only node (rskj), but he will be unable to validate peg-ins and peg-outs. In that sense, it automatically becomes an SPV "lightweight" node, with the same security model as SPV clients get, as soon as there is a peg-in or peg-out transaction.
Therefore we must assure that whatever blocks the bridge accepts to validate a peg-in or peg-out, those blocks are fully exposed (both header and transaction payload) and can those blocks can be included in the Bitcoin blockchain as defined by Bitcoin Core reference software. A SyncChain requires that each sidechain client runs both an instance of the mainchain node and the sidechain-specific node. The main reason we invented the SyncChain is to prevent an invalid Bitcoin blockchain branch to be presented to a SPV-based bridge contract as a valid SPV (header-only) chain, because a SPV proof can be hidden from the honest network, and that reduces M.A.D. Therefore a SyncChain node should run the mainchain reference node, together with the sidechain-only node. In other words, a synchain node runs an instance of bitcoind, and an instance of rskj. To maximize the tension, we want the transparency detect, judge and eventually punish miners as soon as they start mining block for an attack, and before the attack finishes.
Patrick is the United Kingdom’s first PhD graduate in cryptocurrencies. His expertise is cryptocurrencies, smart contracts, applied cryptography and decentralised systems. His work has appeared at Devcon, Scaling Bitcoin, Breaking Bitcoin, CESC, BPASE and SBC alongside numerous academic events. Patrick McCorry is an intern engineer at Infura after Infura acquired his startup, any.sender. Previously, he was an Assistant Professor at King’s College London and an accomplished researcher at University College London, University of Illinois at Urbana-Champaign and Binance Newcastle University.
Our goal is to help bystanders join the cryptocurrency community and Binance provide a level playing field for all. It is very possible this venture makes no money, but who cares when we are all having fun. There is no fee to participate.
There will be no additional lectures or workshops from external companies during the 8 week course. We may include some interactive panel sessions with industry experts to discuss some of the material presented. This is to avoid over-exhausting the participants or presenting content in a way that confuses the participants.
The SyncChain also has some minor downsides. For example, SyncChain cannot provide short settlement finality. Considering pros and cons, SyncChain is certainly a superior protocol for Bitcoin sidechains.
We'll study how something like Bitcoin can work, the implications and beauty of self-enforcing smart contracts, and focus on bringing all students up to date with state-of-the-art research in this emerging area. This includes the history of payment channels (the lightning network) and validating bridges (rollups). There is a special focus for off-chain protocols. This course is taught in the style of an MSc module.Bitcoin
is infamous for its volatility, meaning that its valuation, or price, often swings drastically up and down over relatively short periods of time. This is what makes it an attractive speculative asset for some, but also is a barrier to its adoption as a widespread currency used for exchange.
