I am interested in the case where a fixed pool of signers will sign a series of many messages. As I understand it, musig2 would allow pre-processing, whereby a signature aggregator could collect a list of public nonce pairs from each signer in advance, and then consume one pair from each signer for each message to sign. Signers would need to save the private key associated with each public nonce, and the aggregator would need to signal which one to use for each signature. I wonder, could the public nonce list be generated from a chain code in the same manner that BIP-32 allows a list of public keys to be generated? So, signers would commit to "extended public nonces" (R,c),(S,d), and then the signature aggregator would include a sequence number with each message, to define the nonce key pair in the manner of BIP-32? Or, better, could the BIP-32 sequence number be replaced with some deterministic function of the message being signed? from Recent Questions - Bitcoin Stack E...

Bitcoin funding rates have remained low even when the price of the digital asset has rebounded. The trend for the previous week showed that investors remained extremely wary of the market, and there has not been a change for the new week either. This coincides with the general market sentiment falling back deep into the fear territory. This report takes a look at where the bitcoin funding rates are currently and what it says about the market. Funding Rates Remain Below Neutral Back at the beginning of August, the bitcoin funding rates had finally recovered to neutral, speaking some hope in the market. However, this was only short-lived as the funding rates had declined below neutral the following week. Since then, there has been no significant positive change in the funding rate. Rather, it has continued to plummet, with only a few slight recoveries here and there. The last week was no different in this regard, as funding rates dropped below 0% once more. It was most prominent on th...

Ethereum has been stealing more market share from bitcoin over the last couple of weeks. This is a result of the Merge announcement that took the space by storm about a month ago. Since then, interest in Ethereum has skyrocketed. But with the decline in price, investors are becoming warier about investing in the market. However, that does not mean that Ethereum is no longer a good buy. The Upcoming Merge For many, the news of the Merge is one that has been a long time in the making. This is why when developers announced that the Merge would be happening sometime around September 15th, the community erupted in joy. But besides just being an important upgrade, the upgrade has also served as a good buy signal for the digital asset. Firstly, with the move to proof of stake, Ethereum will consume about 99.95% less energy than it used to. This means that the concern of environmental pollution is eliminated for the digital asset and takes it off the radar of governments who are looking to s...
