An Strategic Context and Activation Timeline

The implementation of the BIP-110 soft-fork represents a critical adjustment in consensus rules impacting block validation via bit 4 of the version field. For a Lightning Node Runner, this event must not be viewed as a simple upgrade, but rather as a UASF (User-Activated Soft Fork) mechanism, where strict enforcement of consensus rules by nodes can force a network split if mining hashrate does not converge on signaling. Starting from the start block, any node running RDTS will reject blocks lacking bit 4, transforming network architecture into a dual-channel system with immediate bifurcation risks.

Here the operational timeline based on the parameters of version v29.3.knots20260508:

Operational Milestone | Block Height | Estimated Date (2026)

Mandatory signaling start (MUST_SIGNAL) | 961,632 | ~August 8–9

Signaling window close | 963,647 | ~August 22–23

Maximum activation limit (RDTS ACTIVE) | 965,664 | ~September 5–6

Bit 4 Evaluation and Split Risk

The mechanics are relentless: miners' failure to comply on this specific bit directly impacts convergence. If the chain with the most accumulated work produces a block without bit 4 after block 961,632, RDTS nodes will split from the main network. This divergence is not merely a software discrepancy, but a fragmentation of Bitcoin's accounting "truth," demanding operational readiness for various fork scenarios.

Fork Scenario Analysis and Hashrate Dynamics

The fate of the network (and yours) is not binary; it depends on Proof of Work (PoW) accumulation and economic incentives. As infrastructure leads, our strategy must anticipate the fragmentation of the original chain (Chain A) into an RDTS chain (Chain B) and a potential emergency response (Chain C).

The resolution scenarios are:

Immediate Activation (RDTS Wins): Hashrate unanimously signals. RDTS activates and the network remains unified. Minimal orphan risk.

Stagnation (RDTS Stall): RDTS nodes find no valid blocks upon reaching block 961,632. The chain freezes for them while the legacy network continues.

Temporary Fork (Deep Reorg): Hashrate splits. If Chain B (RDTS) eventually overtakes Chain A in total work, non-enforcing nodes will suffer a massive reorganization, invalidating prior transactions.

Persistent Fork with Hard Fork (Chain C): If Chain B remains stalled, a new client is launched executing a Hard Fork off Chain B. This introduces a Difficulty Adjustment Algorithm (DAA) and a change of PoW algorithm.

The Difficulty Trap

Chain B's viability is compromised by inherited difficulty. If it retains only 1% of the total hashrate, the average block time would stretch to 16h 40m, taking approximately 3.8 years to reach the first difficulty retarget. This technical paralysis freezes assets and justifies the creation of Chain C, but it also creates a critical vulnerability: indefinite exposure of Lightning channels.

Risk Mitigation Protocol for Lightning Network (LN)

Primary Architectural Recommendation: Cooperative channel closure is the only option that does not sacrifice assets. Lightning channels are 2-of-2 contracts whose validity depends on the immutability of the underlying base chain; a chain split breaks this core premise.

Operational Channel Management Guide (Pre-Block 961,632)

Disable Management Agents: Disable Autopilot (LND) and CLBOSS (CLN) immediately. Automated liquidity provisioning during a split constitutes operational negligence.

Cooperative Close with Safety Margin: "Broadcasting is not closing." A transaction sitting in the mempool at the time of the split is useless if the chain stalls. Closures must be confirmed prior to block 961,632.

Escalation to "Force Close": For inactive peers, initiate a force close taking into account the csv_delay (typically between 144 and 2,016 blocks). If remaining time is less than csv_delay, execute the closure anyway; a frozen asset is preferable to a stolen one.

Critical Risk: The Threat of Chain C (Hard Fork)

If Chain C implements replay protection by modifying the Signature Hash (Sighash), pre-signed commitment transactions (our sole unilateral exit path) become cryptographically invalid. This means funds would be permanently trapped in a 2-of-2 contract, requiring voluntary cooperation from the counterparty (who may be anonymous or non-existent) to be recovered. Chain stagnation does not eliminate "Revocation Attack" risk; it merely postpones it until the chain revives, making it an indefinite liability.

On-Chain Asset Management and Replay Protection

Transaction hygiene is vital. Lacking native protection between Chain A and Chain B, any transaction on one chain can be "replayed" on the other, leading to accidental loss of funds.

Asymmetric Replay Analysis

RDTS introduces new output size rules that allow post-activation coin splitting (block 965,664):

// Post-Activation Splitting Logic (Chain A -> B Only)

IF (Transaction violates RDTS output rules) {

    Confirmation = Chain A Only;

    Replay_on_B = Blocked (Invalidated by Consensus);

}

Critical Note: This asymmetry operates in one direction only. There is no native method to craft a transaction that is valid on B but invalid on A. Furthermore, on a stalled chain (B), coin splitting is impossible because no blocks confirm.

Mandatory Self-Custody Policy

Trusting exchanges is delegating rights over assets on new chains. Institutional policy must mandate: Absolute self-custody prior to the signaling window. Only holding private keys guarantees control over assets across all resulting branches (A, B, and C).

Operational Monitoring and Anomaly Detection

A node may report a "Synced" status while trapped on a dead chain. Surveillance must be multivariate.

Health Diagnostics via bitcoin-cli

getdeploymentinfo: Verify that reduced_data is set to MUST_SIGNAL. Note that the consensusrules parameter in bitcoin.conf is for consent logging only and does not enforce rule execution.

getchaintips: The definitive split indicator. If this command shows a branch with invalid status at a height equal to or greater than the current tip, a split is a physical reality.

getblockchaininfo: Monitor mediantime. A Stale Timestamp (time reference point frozen for several hours) indicates the node is on a minority chain lacking hashrate.

Critical Error Mitigation Guidelines

In periods of technical uncertainty and caos, planned inaction is a defensive virtue. The operational cost of closing channels is finite; the risk of mismanaging a fork is total loss.

⚠️ Anti-pattern Checklist (Prohibited Actions)

❌ DO NOT leave Lightning channels open: This is the most probable and severe loss vector.

❌ DO NOT rely on low confirmation counts (1-conf): Reorganizations are highly probable during signaling.

❌ DO NOT switch software versions (Core - Knots) with active channels: A deep reorg during a software switch can force channel closures and loss of funds.

❌ DO NOT assume a running node is processing the correct chain: Always verify block height against external sources.

❌ DO NOT execute critical transactions: Until coins are split, assume every expenditure will be duplicated across all chains.

 Asset integrity during BIP-110 activation depends on strict execution of this plan prior to block 961,632. Bitcoin's architecture rewards preparation and punishes complacency.

Tokyo ₿ P2P is an actively managed Lightning Network node focused on reliable routing, disciplined liquidity management, and long-term channel health.

- From now on, part of the node’s operation will be assisted by a trained artificial intelligence, especially in two important areas:

Routing fee management.

Channel liquidity analysis and rebalancing.

The goal is not to automate blindly, but to make better operational decisions using current channel balances, routing history, fee performance, liquidity distribution, and recent network behavior. Fee policies will be reviewed with profitability in mind, and rebalances will be considered only when they make economic sense.

Tokyo ₿ P2P will continue to prioritize:

Sustainable routing over short-term volume.

Careful fee adjustments based on real liquidity and demand.

Selective rebalancing instead of unnecessary circular payments.

Healthy channels with active and reliable peers.

Transparent communication with channel partners.

I also want Tokyo ₿ P2P to be a node that is easy to contact. For that reason, there is now a SimpleX group for the node. You can use it to contact me if you want to learn, discuss opening or closing channels, coordinate mutual liquidity, or report any issue related to the node.

TokyoP2P is an actively managed Lightning Network node focused on reliable routing, liquidity discipline, and long-term channel health.

The node currently maintains several active channels with a mix of well-known peers and newer routing partners. Recent management has focused on improving profitability rather than simply chasing a perfect 50/50 balance. Channel fees are adjusted based on actual liquidity and routing behavior: channels with scarce local liquidity are priced more defensively, while high-local channels are kept cheaper to encourage organic outbound flow.

Current node priorities:

- - Keep channels active and monitored.

- - Adjust routing fees according to liquidity and demand.

- - Prefer sustainable routing over short-term volume.

- - Rebalance selectively when it makes economic sense.

- - Build useful paths between peers with real payment flow.

TokyoP2P is especially interested in peers who want mutually useful liquidity, stable uptime, and channels that can support real routing activity over time. If you are looking for a node that is actively maintained and managed with profitability in mind, opening a channel with TokyoP2P can help create more useful routes across the network.
