Bitcoin Gold team finally fixed one of the biggest issues of BTG - according to official Twitter, replay protection is fully implemented.

Bitcoin Gold has just implemented a solution called SIGHASH_FORK_ID replay protection. It is an effective two-way replay protection mechanism that enforces a new algorithm to calculate the hash of a transaction so that all new Bitcoin transactions will be invalid on Bitcoin Gold blockchain and vice versa. This makes replaying transactions impossible.

According to official statement, these are the next steps:

  • Launch public testnet
  • Adjust network parameters
  • Prepare for mainnet launch
  • Deploy mainnet
  • Electrum fork
  • 3rd party Wallets and Exchanges integration
  • Decentralized mining start

 

Bitcoin Gold Hardfork to be Implemented

Modified Equihash-BTG algorithm was launched on block 536200

On block 536200 Bitcoin Gold network was transferred to the modified Equihash-BTG algorithm, not supported by classic ASIC-miners. This is the developers of crypto-currencies reported in the official blog.

Thus, the project promotes one of its main ideas, which consists in avoiding ASIC-mining.

According to the developers, the new algorithm includes personalization, which makes it difficult to redirect the power of mining through the markets of hashing capacities, which guarantees greater network security.

Also in the course of the hack, an improved difficulty adjustment algorithm (LWMA) was added, which will allow BTG to work faster, providing a more stable flow of blocks.

We thank them all for their hard work in recent days getting ready for this upgrade… and for dealing graciously with the few snags and hurdles that will inevitably come after an important Upgrade like this.

We know that this milestone isn’t an endpoint… it’s just a waypoint we pass along the way to better things. First, we’ll make sure everything continues to function as expected, and we’ll help the inevitable stragglers get on board with the new code… and then we have a whole bunch of new things we’re looking forward to sharing with the Community!

In early June, the Bitcoin Gold team said that updating the network will make the cryptocurrency less vulnerable to various hacker attacks. In May, an unknown miner, through a "51% attack" on the BTG network, stole about 388,000 coins from the exchanges.
