It’s a complicated topic, but we can return to Bitcoin as an example of decentralized blockchain security. Gas fees refer to payments made to crypto miners whose computing power processes transactions on the blockchain. This would allow Alice, Bob, and Carol to spend the group UTXO at any time without Dan’s cooperation by creating a transaction with the output Dan previously signed, providing Dan’s signature for that output, and providing a signature Alice, Bob, and Carol dynamically created over the entire spending transaction (which would cover the fees they chose to pay and https://youtu.be allocate the remaining funds however they chose). In a separate schnorr-related topic, ZmnSCPxj wrote a post about the challenges of safely using the MuSig signature aggregation protocol with sub-groups. ● Optech dashboard: a blog post by Marcin Jachymiak introduces the live dashboard he developed for Optech during his internship this summer, providing not only an overview of what information the dashboard makes available to you but a description of how he built it for anyone who wants to independently replicate the data or otherwise extend the dashboard using their own full node. ● Bitcoin Core 0.21.0 is a the next major version of this full node implementation and its associated wallet and other software.
Previously, when your node received an announcement of a new transaction from one of its peers, it requested that transaction from that peer. 1 hundreds of “btcwire 0.5.0/neutrino” connections are downloading TB from my Bitcoin node While running Bitcoin Core 0.21.0 with compact block filters enabled, qertoip notices a large number of connections (75%) and bandwidth usage (90%) from btcwire 0.5.0/neutrino user agents. This allowed the lightweight client to only receive the transactions it was interested in (plus maybe a few extra false-positive matches), reducing its bandwidth requirements. This will help implementers to identify flaws or sub-optimal requirements in the current proposals that might be missed by people who only read the documentation. Implementing transparent and auditable frameworks for the tokenisation of assets on blockchains can help address significant inefficiencies found in traditional means of settlement. This feature was requested to help improve integration between BTCPay Server’s default hot wallet and the optional LN server.
Importantly, the sidechain can operate under different rules, allowing for greater speed and scale. Users on the sidechain can then send sidechain bitcoins to a special contract that destroys them and releases a corresponding amount of the bitcoins previously deposited to the contract on the Bitcoin block chain. ● Upgrade to Bitcoin Core 0.16.3 to fix denial-of-service vulnerability: a bug introduced in Bitcoin Core 0.14.0 and affecting all subsequent versions through to 0.16.2 will cause Bitcoin Core to crash when attempting to validate a block containing a transaction that attempts to spend the same input twice. They keep getting more complex in attempts to abstract away the underlying pyramidal structure, and are coated by – once again – what seems to be an infinite supply of newly produced meaningless jargon. We struggle to even observe – let alone forecast – these complex interactions: replicating and codifying them in a generalised context is a doomed endeavour. 1852 accepts a feerate increase proposed by a channel peer even if that feerate isn’t high enough to safely keep the channel open at present.
The network-wide HTLC limit of 0.043 BTC prevents payments greater than that amount over a single channel. Implementing interactive funding moves Eclair closer to support for dual funding which allows funds to be contributed to a new channel by either of the nodes participating in that channel. ● UTXO ownership proofs or other alternatives: although not necessary for Riard’s initial proposal, some forwarding nodes may experiment with giving credentials to everyone who proves they own a Bitcoin UTXO, perhaps with modifiers that give older or higher-value UTXOs more credential tokens than newer or lower-value UTXOs. I understand some of these changes may be very difficult, especially given the low memory and computational power of secure elements. This may improve privacy, especially when used with unannounced channels. CHECKMULTISIG (less fees, more privacy), and schnorr considerations (lack of accountability, no need to reconstruct the secret key on one machine, less fees, more privacy, additional complexity).
