$BTG testnet upgrade spec and guide
1. Hardfork height: 14300 (2 days)
2. Difficulty reduced by 100x
3. PoW validation & DAA has been changed
4. Full node available at `master` branch

@PhalaNetwork
As an effort to fully switch to
@buildwithsygma
, we have just moved all the $PHA liquidity to the Sygma bridge pool. Now the Sygma bridge pool is the sole biggest $PHA token holder!
Comparing the hashrate of different PoW just like comparing the cores of CPU and GPU. Equihash-BTG is 15x harder than before. Our hashrate was 30M-ish pre-fork and 2M post-fork. It means nearly all the miners didn't leave $BTG.

Totally agree with Coprocessor = Oracle = Rollup = Bridges, etc. You can say by definition, anything running off-chain is an oracle. After all, "Off-Chain Compute Is All You Need" (, kudos to
@0xkrane

But your understanding to
#TEE
is fundamentally…
@WeissRatings
3/ A company can even control 90+% of the hashrate for some coins. The security of them is based on the trust of the company. Are them still decentralized? Oh, my bad -- Weiss Rating is never about decentralization. If I am you, I'd rather rate WeChat Pay and AliPay A+++.
@WeissRatings
2/ What do you mean by "the network is too small"? The number of full nodes is unrelated to the hash power, though we have hundreds nodes on avg. Hashrate is directly proportional to "block reward * coin price". It makes no sense to rate a coin based on the price or block reward.
Awesome analysis on the efficiency of ZKP! I used this chart to explain

Wonder why? 👇
Original question: "TEE coprocessor vs ZK coprocessor, which is better and efficient?"
My answer:
- Efficient: TEE is…
3/ Based on my (very rough) measurements, kappa is anywhere between 10^4 to 10^6 for current systems.
- Theoretical lowerbound from operation counting is about ~1 order of magnitude lower (~10x).
- Abstraction of VMs imposes ~2 order of magnitude overhead (~100x).
@WeissRatings
Very biased. I doubt if your team is professional.
(1) The dominance of the hashrate matters, not abs value.
(2) The upgrade brings the unique PoW, dominate the hashrate, and thus enhance the security.
(3) ETC is just 3.4% of ETH. Don't you think any big ETH pool is a threat>
So many attacks happened in the Ethereum ecology in the past few years show that we urgently need a more safe language to write smart contract. I personally think Rust it’s a good choice, here is why:
container2wasm is a container-to-wasm image converter that enables to run the container on WASM. It converts a container to WASM with TinyEMU-based emulation. Runs on WASI runtimes (e.g. wasmtime, wamr, wasmer, wasmedge, wazero)

The new CAP paradox: centralized operation, dev ecosystem, autonomy system. Apparently Dfinity is following the footsteps of EOS - they have chosen centralization and heavily subsidized dev eco. But how can Dfinity or EOS compete with more centralized AWS or Azure?

More vulnerabilities found and patched by microcode update. It shows how hard the system security is, and how important the TCB recovery mechanism is. Thanks to the great work by researchers, we will have a even more secure computer system.
ÆPIC Leak: Check out our newest attack on Intel SGX. We found that non-aligned reads from the APIC registers reveal stale data, including data processed inside Intel SGX enclaves. We demonstrate the impact by leaking SGX's attestation, AES-NI, and RSA keys and more.

Did you count how many $BCH blocks are “stolen” by the scamming DAA? How many blocks are mined by Bitmain? $BTG’s endowment is time-locked and everyone can check the balance. How the amount of these “stolen” $BCH compared with $BTG?

- The call includes the JS code and the raw request
- The worker hosts a JS engine. It loads the code, executes it, and returns the the result
- Gateway replies the http req…
Bitmain's Equihash ASIC can be an on-chip solver or with advanced memory module (e.g. HBM). A change of Equihash parameter can invalidate it, which is Zcash's and our plan.

$BTG was born in the era of the first Bitcoin civil war,
#UASF
, when people fought against the centralized miners. We believe decentralization is the fundamental of all cryptos. That’s why we have killed ASIC twice and why we decided to develop a new roadmap unlike other coins.
Chainlink is always a closed business. It’s rather a Web2 business feeding data to Web3. I doubt they have any idea what the real permissionless development and composability is.
"Switching off of this time-tested reliability and choosing to connect to contracts run by centralized infrastructure from third-party OEV systems introduces a number of risks"
AKA Chainlink being salty.
Maybe

wrote a great article highlighting how proof of stake is inferior to proof of work when handling the worst case scenarios. IMO, for a robust and decentralized cryptocurrency, PoW is the only way to go.

Paper wallet & blockchain toolbox Coinbin for $BTG is updated. Now supports full transaction signing and even loading from files. (Don't use it as a online wallet unless you know the risk!)
@cryptodavidw
But it just delegates the verification of ZKP to a MPC group, which is usually just 3 peers. It’s like using the worst trust assumption to accommodate the best just in order to run it on Bitcoin.
@NervosNetwork
No, you cannot, blockchain is not made for everything. Is blockchain really necessary for your business? Think twice before making anything on blockchain
IMHO, it would be really nice if some limited

We discussed different approaches (TEEs, FHEs, MPCs, ZK).
